Sudoku.com - Number Games for Negative User Reviews

Way too confusing to play.When I first started playing the game, I clicked the tutorial on how to play, as I read the text, it was quite confusing to figure out on how to actually know why placing this number would be a mistake or not. The tutorial was too little for me to actually understand the concept and it’s confusing on how to know what the order of the numbers is supposed to be. I hope you can read this and possibly, make the tutorial understandable and clearer for players who are new or have never played any type of Sudoku game before. At last, the game does have alot of potential, I just think your developers should try work on how to make the tutorial easy enough to understand for new players..Version: 5.9.0

Free, but a few frustrationsLike paper sudoku EXCEPT—NUISANCES 1. You need to be very careful to tap accurately. Tapping an adjacent number counts as an error and you are locked out after 3 errors. Would be better if you were allowed 15 seconds to correct typos. 2. Lots of advertisements, and some are hard to get out of. BENEFITS 1. You get one clue before advertisements intervene—save it until you are stuck 2. Optional locations are deleted for you as soon as they become illogical. The player doesn’t have to notice..Version: 5.0.0

Ad raging / horrible hintsI am in no need of a sudoku game. I do enjoy it, but I do not enjoy 15-30 second ad pop ups interrupting my experience. It was actually taking away from my time to do other things so in a way, I thank you for helping me remove this app from my phone. Also what’s up with the hints? I was playing on expert and trying to get the hang of little to no details, I narrowed down the 3rd row from the top running horizontal. 4/7 in left box, 3/6, 3/6 in middle section, 4/7 in right box as well as other areas. I hit the hint and it wanted to say I didn’t have enough info in the inner boxes and added back the 4/7 in the middle. If I could show a pic I would. The horrible hint wanted to further confuse what I had simplified. How is someone to be more “advanced” if the hints are the opposite of useful? I later solved the puzzle with no thanks to the hints and also proved that only 3/6 would fit in those middle boxes. This wasn’t the first time I noticed this garbage hint. Though there were some moments when it would help me see where I messed up and how I should have reasonably seen a number I missed. So if the “hint” wants to add numbers to the uncertain boxes, you’d better screenshot it and double check. It sent me backwards on my progress.Version: 5.4.1

Stupid gameEvery time I press a number a mistake shows up I did not even put a anwser yet why is this happening.Version: 5.5.1

Too many adsFirst of all I would like to say, I have had this game for quite a long time, longer than I keep most apps on my phone. I enjoy the daily challenges, event puzzles, and the free play option. My biggest concern is the number of ads that I am having to watch in order to complete one challenge. They are now before, in the middle of, and after every challenge I attempt/complete. After reading other reviews I see that you promised another user that the mid-challenge ads would be removed, OVER A YEAR AGO. I understand that there is an option to buy the ad free version for $5; however, I play this as a way to wind down and it’s not something I play very diligently. I can not justify spending $5 just to remove ads for a game that I might open once or twice a week. I do also understand that ads are how you make your revenue on a free to play game, but it is getting excessive at this point. My fiancé recommended a sudoku app in the Apple Arcade, and I have been hesitant to switch because I have had this one for so long, but I am honestly very tempted to make the change now..Version: 5.3.0

MOST ADS OF ANY GAMEI’ve never played a game with so many ads. The game itself is decent though. The ads affect playability.Version: 5.4.1

Used to be good but now it’s too easyI needed a game to play offline on the underground and chose sudoku because I am genetically predisposed to alzheimer’s and I thought it was good exercise for my brain. I was happy with it and bought it, and I got rather good at it but couldn’t always solve it (I could never spot an X or Y wing), which was fine with me, I liked the challenge, the reasoning and the fact that winning wasn’t a given. I stopped playing when my commute moved to the overground and I could read the news instead. Two years later I came back to this game and was very excited to see that they had added a difficulty level (evil until the last update, now master). However all the difficulty has gone. Master level is now barely what medium used to be. I have solved it in 10 minutes without even a hint of reasoning, just by exclusion. I have played quite a few times now and every game is like that. They have improved the functionality but ruined the game. What used to be a good sudoku is now boring and unchallenging, therefore pointless unless you’re a total beginner. But I suppose if you are, it’s good for learning with the hints explaining how it’s solved, only you’ll get bored soon and I doubt any new players will keep it long enough to want to pay for it..Version: 5.8.1

Annoying features without configuration optionsEdit 1 month later: still freezing. Lately the app is freezing on an iPhone 12 Pro Max which should be one of the best in performance. They implemented some features that you can't shut off, like adding boosters. And keep popping up in front of you. Also, for some reason, once you place a number, you can place a wrong number at the same cell and it will simply fail your game. This is specially problematic when it's freezing because it will delete the correct number and place another one. Edit: as per developer response to open tickets. I did it twice, and they were simply closed with some unhelpful responses..Version: 3.8.0

A great sudoku app - when it works!I’ve played this app regularly over the past couple of years, and can recommend it as one of the best - I’ve previously rated it 5 stars. The reason I’m downgrading my rating now is that, over the past few weeks I’ve noticed an increasing number of ads in this App that “time out” with no exit option (ads normally have an “X” in the top right corner to close them after they’ve run). This leaves the player no option to return to the game in progress but to hard re-start the device and lose any progress made. It’s becoming such a frustrating aspect of using this App that I’m considering changing my allegiance to one of the other Sudoku Apps out there….Version: 4.9.1

FreezesScreen freezes and unable to progress . Uses a lot of battery playing.Version: 4.9.1

SomePuzzles are incorrectI’ve come Across quite a few puzzles that are incorrect. Even when I use the hints, the number they show me doesn’t fit..Version: 5.5.1

PLEASE READThe 2 starts missing are because of my brain tells me to change the number so I can do this one but I’m on a correct number but I click the number I want and it just goes red then my face goes red so if you could make when you finish a spot make so you can choose the number while the search is off That’s all I need thanks..Version: 4.11.0

SudokadThe sudoku works great. The ads are obnoxious. More so than ads usually are.Version: 2.3.4

Forced to play certain levelsI used to love this app and played it daily several years ago but now it forces me to play easier levels before I can get to the harder ones. I already completed 287 hard levels and 41 expert levels years ago. I have limited relaxation time and don’t have the time to play through and reach the harder (and more fun) ones. Seems easier to just install another app. I really used to love it and I don’t know who thought this was a good idea..Version: 4.12.0

Plagued with adsApp works well, not a good tool for people trying to upskill as any time you need a hit you have to watch a 30 second ad. Many other apps do not have this ad spam. Cheers.Version: 4.11.0

Evil puzzlesEvil puzzles, not evil. Too easy.Version: 5.5.1

Fun game, but lots of adsI love sudoku and have since I was younger. I downloaded this app a couple years ago. When I first downloaded it, the ads weren't too bad. They only came at the end of a game, which is reasonable for any free download. Now I get at least 2 during a single game and it's really annoying. It's annoying to the point where I will go weeks/months without playing on this app, only due to not wanting to deal with all the ads that interfere with my game. It gets so obnoxious that I will quit playing in the middle of a game, when an ad pops up, just so I don't have to waste my time watching it. The other thing that bugs me is that when I win a game, it will say that the time I finished at was my fastest time (for that particular level) when I know for a fact I've gotten faster times at said level. I don't really play to keep track of my times, so it's not too big a deal. I mostly just wish it only did that when it really was my fastest time, instead of seeming to circle through "achievements". I don't need a participation trophy 😂 Other than that I love that I can customize my settings. I love that there's no wasted paper. I love that I can turn off the setting that tells me if I got something wrong, but can turn it back on if I'm stumped about where I made a mistake. I love that I can challenge my brain on my phone instead of always mind-numbingly scrolling social media. Get rid of all the ads during games and I'd probably play more..Version: 4.14.0

Too easyMost of the puzzles are too easy even in the ‘extreme’ mode. The monthly challenges/events start off with 10 or so easy puzzles which just take up all my time trying to reach the more difficult puzzles. I do like the ability to add pencilled numbers in multiple squares, and 3 errors limit for additional challenge. The hints don’t feel like hints as they only add a number and I have no idea how it got that number, or whether that was the next step or just a random number I hadn’t figured out yet. Would also be good to have a catalogue of the puzzles to pick a particular one to do. And maybe extra types of sudokus like thermo sudokus or killer sudoku..Version: 2.8.0

Keeps CRASHING since update!!!😡Fantastic game, can’t stop playing!!! It’s my go to game! However since your latest update while in the middle of playing the game, it keeps crashing.. the screen goes completely black except for the advertisements at the bottom of the screen! I’ve tried closing the app and restarting the game but it happens again immediately after opening up the game. I’ve tried starting a new game and again the screen goes black all except for the advertisements at the bottom. Then I tried deleting the app and reinstalling it and guess what? It happens again! No other apps do this on my iPad so I know it’s not the problem, plus if it were my iPad then the advertisements would go black too and they don’t. Every single time the screen goes black it still shows the advertisements at the bottom and the rest of the screen is black! I pray you get this fixed ASAP! This is my favorite game to play on a daily basis and since I couldn’t play using this app anymore, I was forced to download another sudoku app in order to get my daily sudoku fix. I will however continue to check this app regularly to see if the problem has been resolved or not but in the meantime I’ll be using another sudoku app!.Version: 2.3.0

Crashes nowSince aug 26 update it crashes an unable to use.Version: 1.1.1

Ads interrupt game playOpen app, watch an add, start a game, watch an add, finish a number, watch an add, yea, every time you knock out a number, they play an add. Finish a game, watch an add, start a new game, watch an add. <edit> Latest set of ads full of bugs, 1 in 7 freeze, eventually crashing app. Just lost 30mins progress, not happy but recognise not directly dev’s fault. <reply> Thanks Dev, well aware how ad supported apps work, and have dozens of payed apps, but I’m a firm believer in paying for well made apps, not paying simply to remove ads. The game is good, simple and intuitive. The issue is not the ads themselves, simply how frequent they are shown and how they are placed. Specifically, long add shown on placement of correct number, lost train of thought by the time it’s over. Rating increased from 1 to 3 stars for 2 reasons, 1 for taking the time to reply to a critical review, should be commended, thank you (albeit scripted and missing the point, but points for trying)! And the other because the horrific onslaught of ads initially is a function of speed progressed through low levels. Once settled into longer games, it’s not 5 ads a minute, but original point remains, they interrupt train of though this gameplay. Banner add at top or bottom of game board would work, cycle every minute or more, still gets eyes on it without interrupting..Version: 5.3.0

Too many ads! Deleting the app…For at least two years reviewers have been telling you that there are too many ads, they are extremely intrusive and spoil the game experience. You promised to reduce the numerous number of in game ads, but this is hasn’t happened as I have recently experienced. Why have you not removed these ads as you promised so often in the previous reviews? Seriously consider making the ad free cost a bit cheaper and you might get more uptake instead of turning people off the app. After such a poor experience I am deleting the app..Version: 5.6.0

Too many adsEvery time you do anything its rewarded with an add, finish a sequence of numbers = ad, finish a game = ad, want to undo a move = ad, Apart from the mass amount of ads swarming you every single thing you do, game works fine and smoothly, but too many ads makes a person change apps,.Version: 5.4.1

Bad, this games sucks for beginnersNumber one, I don’t understand. why is it telling me i’ve made mistakes when I haven’t (ex. I put the number 7 down and it said I made a mistake even though the square and the columns showed no 7 in them). number two, what am I supposed to do when there’s literally every number in a column (I was looking for a number to choose, but after counting 1 through 9 I realized those numbers are already in the columns and square) like, make your rules more clear not everyone has played sudoku before.Version: 5.5.1

Too many adsI have loved using this app for years but will be deleting as I can’t take the incessant ads that keep popping up! In 1 game roughly 4 ads will take you away, making you wait about 10 seconds before being able to click out of them. Absolutely shocking and completely ruins the apps experience..Version: 5.5.0

Hints are a hindranceWhat set this app apart from the numerous other sudoku apps was the amazing educated hints. They’ve updated it now where the hints are useless. It’s tries to undo the work you’ve done, suggesting you’ve missed notes when actually I’ve removed them for a reason and there is no way to reject this hint other than closing the app. It renders the hints redundant because it’s actively undoing the progress you’ve made. I’m really disappointed, I really enjoyed this app and it made me better at sudoku but now that’s gone I may as well use another app with less ads. I’ve read what the developer has replied to others with the same complaint but it doesn’t really make sense to me. Implement an option to turn off educated hints if it’s such a problem. Why ‘fix’ something that isn’t broken?.Version: 5.1.1

Best sudoku app; but very glitchy, crashes my phone and freezesThe gameplay itself is really great when it works well; the only thing that I would recommend to the developers is to lock in a correct answer when it’s been entered. It’s very frustrating when you’re finishing a game and get a “mistake” when you click an already found answer - it can be undone and count against you, which just makes no sense. But the major issue with the game is that it has frozen my phone twice (so I can’t even lock it or turn it off; I had to figure out how to restart without using the screen). It also often generally freezes and slows down (so when I click on a box it takes about 5 seconds to react). It’s unfortunate; I hope these things are fixed in future iterations. But thanks for the great gameplay all the same!.Version: 4.9.1

Keeps giving me impossible puzzles!!For months, even after updating this app, I keep ending up with puzzles where the same number appears twice in the same column or row - as in I’ll go to add the final number to a row (so I already know the other 8 in the row are correct) and that final number already appears either in the corresponding column or box!! It’s infuriating, I have to keep abandoning puzzles. I know I can’t have made a mistake because none of the boxes flash up red until I put that erroneous double-number in there. And it happens very frequently, it’s not an occasional one-off. It does this on medium and hard, I don’t play easy so haven’t seen it there, and can’t remember if it’s happened on expert. A big shame as otherwise a really great app..Version: 5.1.0

Obnoxious adsI started playing this game in 2019. I’ve always loved playing it. Compared to most apps the ads have always been short compared to a lot of different games I’ve played. Within the last year, however the developers have changed it so that the ads now pop up a few different times in the middle of the game. It has decreased my enjoyment immensely and I have been playing a lot less..Version: 5.5.1

Recent Update to featuresThe most recent update makes all the numbers highlighted when you use “first-number input” setting. It was not like that before the update. As well you have a setting that highlights same numbers. So could you please remove that feature of the “first-number input” or keep the settings separate like before. I will wait for what happens next. Whether you see it or not meh. Just makes me not want to play sudoku for while. Thanks.Version: 3.8.0

Too much battery drainFor a simple game it takes too much battery. Had to delete it and downloaded a different app.Version: 1.2.7

Ads are really annoyingAds are 30 seconds a piece and if you move out of the app, you gotta watch an ad AGAIN before resuming your play. I listen to music on my phone while I play, so this has been SUPER annoying anytime I have to change a song. Deleting for this reason..Version: 5.5.1

FrustratingI can put up with adds at the beginning of the game, I can put up with the adds that take up some screen realestate. But stop interfering with full screen adds in the middle of the game. Three to four interruptions in the space of one game. The browser version has become my game of choice due to the excessive advertising..Version: 5.6.0

Annoying addsToo many ads while playing.Version: 5.4.1

Too long -and midd game- adds.Interface is 5 star with its easy to use design but the adds are way to long - and in the middle of the game so you loose focus. Very disappointing. $9 for add free is a bit to much for a casual user..Version: 5.0.0

Good you may need a pen and paperI was really disappointed to find an expert puzzle that suggested ‘Bowman’s Bingo’ as the means to solve. This is a brute force method that basically entails trying an option then working the puzzle to success or failure. The problem is the interface has no mechanism to allow for advanced markup to facilitate this, if you choose an incorrect number in a cell it will tell you straight away if it’s wrong. We need a mechanism to checkpoint and return. Or, copy it to paper and solve outside of the app. Also it is not possible to add pencil marks to the outside of columns and rows which is a practise I sometimes like for a different viewpoint. It would also be nice to block select cells by hold and drag to mass edit pencil marks..Version: 4.14.0

BadThe instructions/rules made no sense at all, and you only get 3 lives😤.Version: 5.5.0

Update changesI don’t like the new updated version, the letter fonts are different and not as good as it was before, very unhappy.Version: 5.5.1

Stop interrupting my gameI’m taking off one star for the inability to mute ads and one giant star off for interrupting my game multiple times with an ad. Seriously? In the MIDDLE of a sudoku game you throw in ads?.Version: 5.5.0

Obnoxious and deceitful ads. Play on the web instead.The game is interrupted every time you finish a number, box, or line and after the ad your flow is gone cause you’ve lost track. Some of the ads don’t play out like commercials but instead present a screen that’s designed to trick you into thinking it’s interactive so you’ll click it and be kicked out of the game completely. On top of that there’s always an ad bar at the bottom that never stops moving and it’s hard to ignore. The ad that made me delete the app was a banner with a fake, bright, strobing message notification. On top of being the most distracting and annoying ad I’ve seen in my life, it’s also terrible cause those kinds of ads are deceitful and are how people get viruses. It’s a shame cause the app is built well otherwise and I would have put up with the ads if they didn’t feel like a punishment and weren’t designed to manipulate people by lying to them. I’m not falling for it but there are plenty of people who will and in the future it will lead to them having their identities stolen. Shame on you for allowing those kinds of ads..Version: 5.0.0

Was perfect, now barely playable* I appreciate the devs responsiveness, upped the rating by a star. This was the perfect balance of everything before. Recently I updated and now anything I do results in advertisements. If I just pause the timer willingly, I can’t return to the game without an ad. Any time I finishing finding all of one number on a board I get an ad??? Completely ridiculous. Just too many examples of ads interrupting a game where I’m trying to get a good time on the board but interrupted over and over. Awful now. Looking for a new app. *Developer response: It is completely understandable that the app has ads, we all know that free apps need to run ads to sustain them. The problem isn’t just the fact that there’s ads, it’s the frequency and the timing of when the ads are interrupting the experience of the application. If during 1 game of sudoku (roughly 5-10 min on average I’m guessing) there are ads interrupting anytime a user needs to pause, completes a box, or completes all instances of a number on the board, it becomes a pretty sizable time of the gameplay and pretty much ruins any momentum for people playing the game, which as we all know is part of sudoku as exponentially things get quicker the more you figure out. It’s not really just about ads existing on the app..Version: 5.5.1

Painful!!Not really special. Extremely irritating with the ads at the bottom and full page when finishing. To remove the ads the cost is ridiculous at $12! I have another purchased Sudoku at much less that I can Family Share. This is just not worth it! As I said the price is too high else I would have. However. It can't be shared on Family Share..Version: 1.2.1

AdsThe game changed today and I spend more time waiting for ads to finish than I do playing. I have been playing for many years and now will likely delete the game..Version: 5.5.1

It’s just sudoku....Sudoku, it’s an age old game. Countless apps on the App Store for it. So please tell me WHY ON EARTH there needs to be so many ads??? I hope the developers know that there is NOTHING special about this app’s game play that would warrant me sitting through a 10-20 sec ad after every game (regardless of whether or not I win). The UI of the actual game is clunky: I constantly mistype numbers bc they’re so close to each other, accidentally tap the ad banner at the bottom (redirecting me to a whole different screen), nothing special or catchy about number input, too many steps to switch from notes to numbers (important for when ur trying to beat a time), the list goes on. I know there isn’t a perfect app, I get it. But with all this in mind, devs continue to shove the most LITERALLY THE MOST ANNOYING ads Ive ever seen down our throats. Instead I can and I will go download one of the numerous sudoku apps at our disposal currently available on the App Store that actually PRIORITIZES user experience over $$$$$$..Version: 2.2.2

SlowOnce the app got to a higher level ads started to freeze or were slow. Plus instead of ad at beginning and the end now have ads in middle now too. Dropping this game too frustrating. Feels like to me, if you don’t pay you don’t play. I don’t know which advertised app is freezing as all I see is am black screen and a white x appears in upper right corner. I have already deleted this app. No further action required.Version: 4.11.1

Rewarded with more adsI get the free games have ads and I understand that , but when I’m in the middle of a game and finish eliminating one number from the board , and get a reward of it breaking away to another ad even though I just watched one , is not only really annoying but greedy and unnecessary. I can’t get over that , the reward is another ad . It def makes it difficult to concentrate, when I get going and I get in a zone and start breaking it down , to have it cut in the middle of my game for every number eliminated smh there is a very basic process in getting a game to be addictive and that’s the reward mechanism in your brain . If every time you achieve something , you get interrupted, it’s like Pavlov’s dog, you are conditioning me to be repelled against achieving any numbers to completion . If it was just ads before each level I could deal with that but I cannot play a game with this many interruptions . Idk how this is so highly rated , maybe it didn’t used to be this way . Part of why I like sudoku is getting into a meditative state while solving . That’s just not achievable here, there are better options ..Version: 5.3.0

Do not download!!If this app operated correctly it would not drain your battery by 20% in 9 mins.. if the developers try and tell you to buy the ad-free version then this would be blackmail with your battery health at ransom!! I have disabled the app from using data but it continues to make my antenna red hot.. my phone is pretty new and don’t have any other problems with other apps and battery issues. Just this app!! I will find a way to notify Apple store and I might even seek compensation for damages to my battery health! There are other apps out there that still have ads and do not drain your battery. It’s almost like this sudoku app want you to spend money on their app.. this has gone long enough!.Version: 1.2.7

Too many intrusive adsThe games itself is good but the ads are too intrusive, they fill the whole screen, you can't skip for a while and they come up very often..Version: 5.6.0

Too Many AdsUsed to be my favourite puzzle app. Very satisfying to complete a puzzle. Unfortunately the ads have gotten out of control. There used to be one ad in between games but not there about 5 ads during each game which ruins your train of thought and the satisfaction when trying to complete a puzzle as quickly as you can. You have driven away your most satisfied users with the increased ads. I have uninstalled the app and won’t reinstall it until this issue is fixed. The developer please actually respond to this review with something other than generic PR speak..Version: 4.11.0

Great game ruined by adsThe game itself is really good, and I don’t mind ads in a free game, but allowing ads to interrupt your game midstream and ruin the flow of the game is terrible. I’ve also found the ads are able to change the orientation on my iPad and sometimes even bypass the orientation lock too. I’ve seen comments from the developers that they will remove mid-game ads but those comments are now more than 6 months old. I hope they will reconsider..Version: 4.12.0

A weird update that never went awayThis is by far the best sudoku app on the appstore. Its simple, clear and fun with the events. But this one update that they did a while ago haunts me. The fact that you can’t press hold and lock a number in without highlighting the location of every other place that number is. They used to let you turn that setting off and you could just lock numbers, making it a lot easier to play with one hand on the train or when walking etc. I use the app regularly so this kind of change made me play a little less. Its almost perfect other than that one issue. I don’t know why not just add a setting to let us turn off that feature? Its really really bad :(.Version: 4.8.0

Too Many AdsThe ads pop up after you pause a game, when you’re on a winning streak, if you make a mistake. The ads are also a couple minutes long and that is super annoying especially when you’re doing well and then an ad interrupts. All the ads take the fun out of this game..Version: 5.5.1

Terrible UISo many UI frustrations! I’d turn on notes, make some and then turn it off so I could mark a different square with a number - and all my notes would be marked as wrong answers! No, no, no, they’re still just notes! I also had to be very careful to start my game by clicking on an existing number. If I clicked on an empty square the game would fill it with a number - when I didn’t mean to fill it with anything yet - and more than likely it would be wrong. And once I made a wrong guess on the last instance of a number. The game hides the number in the navigation row at the bottom when you’ve finished marking every instance of that number, and that’s exactly what it did even though my last guess was marked wrong. Absolutely no way to fix it! I gave up after two games that end early simply because I clicked in the wrong way. Deleted app but would be willing to try it again (and re-rate) if these problems were fixed. Confirmation asks or toggles would be nice and greying out the nav numbers instead of disappearing them would be helpful. Ignore notes as guesses in any mode..Version: 4.12.0

The latest update made the game worse.I have been playing sudoku on this app for a long time, so long that i’ve completed every single daily challenge available. I loved the mechanics of the app and the simplicity. I really didn’t mind the ads either. The latest batch of updates not only added ads in the middle of the levels, which wrecks the flow of the game, but they also removed the most novel part of the game, which was the hint button. It used to SHOW you, step by step, how to improve your gameplay and give you a helping hand. It would allow you to see where you need to go next to solve the puzzle. Now, all it does is fill in a random box without even showing you where it filled in. If you blink you’ll miss it, and it seems to have no rhyme or reason to it. ik these are all trivial, but I loved the aspects of the game before the updates, and now it feels a lot less like it was made by someone who actually plays the game and wants others to enjoy it, but by a company who wants to run as many ads as possible to make money. Just bring back the helpful hints feature at LEAST..Version: 5.4.1

Expert games full of impossible gamesThe game play of this Sudoku is excellent. Really easy to populate the board, erase mistakes and the gaming levels validity set correctly. There is a major issue with Expert level though - as others have reported. For example, I had one new board that did not have a single move. The “hint” showed nothing to fill. I logged a help ticket for this. Another instance of the issues is that when you believe there are no more moves, press hint - you get a resolution that says, for example, put 7 in this square. When quite clearly the 7 could have also gone in another square in the same section. Again a ticket raised for this. Too often you get a Hint that simply shows all the possible numbers that can go in each square given the progress you’ve made. Again this can be multiple options for every square so you have to guess at one with only 2 numbers in. Not good enough. You never ever get this in a hard copy expert book so why on here? The Helpdesk do respond quickly but have a denial slant to them. Worth the purchase if you can cope with the frustration of knowing that if you start an Expert game there is no resolution..Version: 3.3.0

Horrendously Bogged down with adsI have been considering purchasing the app just until recent. Lately I've been turned off all together with the absolutely obnoxious amount of ads. Previously ads use to pop up after finishing a puzzle, so I figured I'd buy it and be rid of them but I've been getting them after nearly every move I make now. Will be looking to purchase another sodoku app - the Overly aggressive and constant bombardment of ads to the point where it's unusable is just a gross way to get you to buy. Can't support a business practice like this..Version: 4.13.0

If it ain’t broke….Was a great app before update 1.5.0 in February. Changed the style and font type, plus holding down the number to highlight the one you want to repeatedly use is now slow and clunky (annoyingly so). In addition, when trying Expert to build my skill, if I use “hint”, it now asks which cell I want the answer to….I don’t as I won’t learn anything. Poor “improvements” in the eyes of a paid up customer. Having just read some of the other recent reviews, I have no doubt I’ll receive the exact same dry response from the developer about going into their website for tips. I don’t want to log onto a website mid game 🙄 UPDATE: Reduced to two stars. Received a message to my original review stating that they were disappointed by my review and to email them directly, with the suggestion of looking forward to my response….so I did …received a ridiculous email in return as to all the other responses they put on here. Why as me to contact you if you’re just going to continue to fob me off??? Not only taking the enjoyment out of their game but wasting my time too…thanks! Biggest bug bare on tips is “these cells are filled out incorrectly”, when they’re not! If you pay for something and the service breaks through designer fault, in many instances they’re at liberty to fix or refund…will I be refunded for a increasing poor app???.Version: 5.2.0

Advertising AppAds ads ads. Ads before each game. Ads every 2mins. Ads when you finish a game. Ads you can’t skip. Ads which hide the x to close them. Some ads require 3+ taps to get rid of. Want hints? You’ll have to watch ads for 30+ seconds. Really takes you out of the flow of solving..Version: 5.6.0

Getting tired of same adsSame ads repeatedly coming up and tired off losing so much time fighting to close them down. One huge pain wouldn’t buy products you force me to watch..Version: 5.5.1

So many adsI have just played today’s daily challenge and the game was interrupted numerous times by ads. Until recently there was maybe one at the beginning and another at the end. Lately the games have been interrupted in the middle with another ad. Today’s challenge I’ve done in between visits and chores during the day. Every time I open it up, another ad. I’ve just spent the last ten minutes (or less) completing the challenge and in that time, there was an ad on opening, an ad on finishing, and at least another two ads during play. What’s with that? Is it even worth playing anymore?.Version: 4.7.1

Game itself good, but ads are ruining itThe game itself is really good, easy to use layout and probably my favourite Sudoku game on iPhone. It has been ruined by the ads though. I’m more than happy for ads to be included in game to ensure it stays free, that is a fair price to play but they have introduced ads mid-game which totally ruins it. Adverts before and after the game, no worries, go for it. Ads in the game menu would even be fine. Ads along the bottom of the screen during play don’t bother me. But full screen ads popping up right in the middle of the game is so frustrating. They’re skip-able after five seconds but even so they ruin an otherwise really solid game. It feel as though they’re just trying to irritate you enough that you give in and pay for the ad less version..Version: 4.15.0

Stop forcing new features on usResponsible developers introduce new features with at minimum an alert panel identifying changes. Even better developers add features with option switches to turn off the new coolness. This developer does neither — adds things their team can’t resist and surprises us with added crap or lost functionality. I’d give this game zero stars if I could. This developer, in their infinite wisdom, just killed a major nicety of this game: Until today, if I wanted to add multiple numbers to the notes for a cell, say 1, 4 and 7, I could just swipe down that column. Learning the various swipe patterns was fun and useful. Gone as of today. I’d give this game zero stars if I could for stupid project manager decisions. Overall, pretty good game. But there are issues: First, the constant “play Killer Sudoku NOW!” is getting really old. Tried it, hated it. Enough. I should be able to say no thanks once and be done. Second, the developer just introduced their new “Evil” level. Fine. But they also changed the game so that you have to “earn” a level by completing a certain number of lower games. Sigh. Okay, fine. But the developer also forced this new regime on those of us who’ve been playing all levels before, and locking us down to the “Easy” level to work our way up. Which is such a lame, boneheaded move I may delete the app so that I don’t tacitly support this crap..Version: 5.5.1

Very sluggishMy iPhone X gets hot and the game freezes for several seconds at a time trying to enter numbers. Seems to be getting worse but quitting the app didn’t help, a reinstall helped but I lost all trophies, so not much incentive to keep playing..Version: 4.11.1

Ad riddled, and only way to solve is by watching them.Medium level is too easy, hard level not possible to solve without pressing “hint” button. The solution given states the square as the only possible one left for a particular number, when it clearly isn’t. So in order to solve the grid, you either have to guess or press the hint button and watch a 30 second ad. Hard level should still be able to be solved with logic, thinking multiple steps ahead. Leave expert for guessing the unknowns. Medium level is too easy, so of course most people play hard. And that’s where all the ads are. Find a different sodoku app, skip this one..Version: 4.16.0

Far too many adsI used to play this game a few years ago and it would show an ad maybe before or after a game and if you need a new hint which was okay. Now, there are ads everywhere, when you enter a game, too many mistakes, need a new hint, filling in all of one number(this can apply to multiple numbers in a single game), exiting the game. Really kills the game, I also read a review that you replied too and you stated you would remove mid game ads. If anything it is worse now..Version: 4.12.0

Great Sudoku app, but the ads served up are false and misleadingThis is a really great Sudoku game. I play on easy mode against the clock to give my brain a quick workout, or expert mode when I want a long challenge. Game implementation is strong. However the ads are a problem. I don't mind ads, I understand that this is an important revenue stream, but I do have two pieces of feedback. Firstly, I would prefer to see an ad before my hame starts than at the end when I have succeeded with a puzzle... It feels like my reward for winning is to watch an ad, instead of celebrating a good result. I think i would be more tempted to play again if things worked this way around. Maybe worth trying? Second, I am really put off by clearly misleading ads for games like gardenscapes, Fishdom and now Envoy. The ad agency supplying ads to your game depicts these games as logic puzzles where you move barriers to help a character escape or find treasure. These are nothing like the actual game play at all. I appreciate that some of this is not your direct responsibility but the ads are showing up in your game, and not elsewhere. I strongly doubt that the ads would be permitted in the App Store, for example. Sorry for the negative review because it is a great and well written game, but people should be aware of the ad situation..Version: 2.5.0

So many adsThis is a fantastic app and I have enjoyed playing it. There are however far, far too many ads which break the players thought pattern and hinder progress. Yes, there is a way to remove ads for real money but there shouldn't be this many ads to begin with. You get one ad at the start of a game, three during the game and another at the end. I don't mind some ads but seriously? Five ads a puzzle? Please review the ad situation..Version: 4.13.0

Frozen after playing for 2minIt's soooo frustrating that you are trying to break your fastest record, but the game gets slower and slower after the first 2min of playing, and finally, complety frozen. Trying to restart the game? Nope, because your whole phone is frozen from this game! One extra star is for the game itself when it's playable, although the technical issue just makes everything meaningless: why bother considering if a game is fun to play or not when you cannot even play it for more than 5min?.Version: 4.12.0

A Good game ruined by adsThey interrupt gameplay with ads..Version: 4.13.0

Too much pop-upsHad to delete because the ad popping up got INTENSELY annoying. Like sudoku is meant to be a calming and thoughtful game, and getting interrupted by pop-ups just ruined it. By the 4th expert puzzle I attempted, I couldn’t even complete it because I was too frustrated with the pop-up. Like this isn’t supposed to be some cheap kids money making ad generating app. Like you could get away with ads in between puzzles. But during the puzzle no way. Sorry had to delete. I remember having this app on an old iPhone a year ago and not having this problem. But now I’ve come to realise that you can’t download any apps anymore because it’s just ads..Version: 4.9.1

Annoying advertsI’ve been doing the daily challenge on both my iPhone and iPad for over a year and just recently it’s become intolerable because of all the interruptions and time wasted while ads for mostly stupid games are run for about 30 seconds. Now, whilst in the middle of a puzzle, ads are being run, which can interrupt a train of thought and are very annoying. It never used to be like this - there were some ads but nothing like you have now. It is ruining the game for me, and I will be deleting both at the end of the month if things remain the same. I used to enjoy doing the daily challenge but I’m finding it annoys me more now instead of being fun..Version: 4.7.1

LevelsAdds that stop you playing half way through the game are distracting. Not consistent at each level.. some are easier/harder than the level you choose.Version: 4.8.0

Good but drains too much batteryThis is a very good sudoku game app. I find it very easy to use, with many sudoku puzzles available. Ads are not too bothersome. Main problem is that it drains ridiculous amounts of battery at a time. I don’t understand why, considering the game doesn’t look very demanding battery-wise. For example, my phone battery went from 60% down to 26% in only 3-4 minutes of playing the game. Impossible to play without a charger, and a shame since it is a good way to pass the time if I want to, for example, go on public transport..Version: 2.1.1

Too many adsThe volume and frequency in which ads interrupt your game play (also the super fun unskippable ones) makes for a frustrating experience with this game. Not only should you avoid this game but I imagine everything from this developer is going to be ad ridden and nearly unbearable to play..Version: 5.5.0

Way too many adsI love this game and have had it for many years and I’ve completed well over 22,000 games in medium difficulty but the ads have now gotten completely out of control. Ads used to be played between completed games but for the last month or so the amount of ads have dramatically gotten worse. It went from a 30 second ad between games, then a ad was played every time you completed a line and/or a number and now I’m getting all of the above and ads every 45-60 seconds. Often 2 ads will play at the same time. This has now made the game completely unusable. Really disappointed I’ve lost my favourite game until this gets fixed..Version: 4.9.1

Bad ChangesI knew something felt wrong with the last update. I know the design has been overhauled but there are some things I’m really upset about. The notes/hints being changed telling me that I have missing notes when I’ve intentionally removed numbers. I’m really upset about this because I’ve gained so much of my knowledge and tricks from this app. How will new players understand hidden doubles/bowman’s bingo, y-wings, etc if the “hints” are just filling in random squares. That’s not hinting, it’s solving. Also, I really loved going back and playing previous monthly challenges. You used to be able to hit the trophy button and click on the month you want to complete. Now you have to go to daily challenges, and swipe backwards to try and get to the month you’re completing. Super frustrating. It seems that the update also reset my average scores and winning streaks. And the timed challenges I love so much are 50% easy/medium when they used to be mostly hard/difficult. I hope some positive changes come soon, because I spend way too much time on this app, but I can feel it dwindling..Version: 5.1.1

Decent, but the mistakes limit is awfulI like brain games and this app is a decent digital version of sudoku but there are some strange problems. Example being the "limit mistakes" setting which does nothing; you can restart the game, wait, restart the app, no matter what you'll get screwed over by the mistakes. Hit one wrong button and the game boots you, and by mistake I mean hitting the wrong button, because sometimes the notes are off and you're just trying to mark a possibility, nope, you're a dunce for not seeing the slight difference in colour. To be fair, this might just be me but the fact that I can't let myself make a few mistakes more than the crazy difficult tiny three limit is upsetting. The setting is there; why doesn't it work. This is a big drawback for me but besides that the app is just fine: good UI design, nice looking, it's easy to tell when you've done right and what you started with, generally pretty good. But that one problem that I presume to be a glitch or a miscommunication really takes a lot out of it..Version: 2.7.2

LaggyThis Sudoku game used to be awesome. I could play a few quick games most days and it worked very well. Unfortunately with the last update and adverts it’s become very laggy during actual game play which is really effecting my finishing times. It’s no where near as responsive as it used to be. Sometimes it can take any where up to a full second to register your input which really slows you down and causes you to second guess and make more errors. It’s quite frustrating especially when you’re trying to speed run Easy.Version: 4.12.0

Be prepared.After reading through a lot of the reviews and focusing on the ones with developer comments it’s clear that the developer writing the comments hasn’t actually seen any of the ads that they keep saying “ads can be skipped after 5 seconds” some probably can, but for the most part attempting to hit the small area that says it will skip the ad will just send you to the App Store to download whatever random thing, and most of them won’t even allow you to skip for at least 30 seconds. Closing the app out when you get an ad that you are having difficulty closing/skipping and loading back in, you are met with another ad… this loop is what makes this very irritating, turning a once ok experience seem now very predatory and greedy. I used to have fun with this app, but have since deleted it. Ads were way to irritating now. And I’m not willing to spend money on something that I may only play for a few hours over the course of a year. Hopefully this changes. I’ll be back in a year or so to see if it has..Version: 4.15.0

AnnonceUn jeu vraiment le fun, mais trop d’annonce bidon.Version: 5.5.0

Mostly good, annoying bits don’t compensateI’ve been using this app for a while but am finding another now as their latest change in adverts is just too annoying! I could cope with a permanent ad bar at the bottom flashing away at me, I could cope with having to watch ads between games and on achieving certain things within a game, however now, an ad pops up randomly which has to be swiped away, sometimes several times within a minute. Too much!! Plus, even though it’s not possible to put the wrong number in a box, it is possible to accidentally change that number to something else and lose a life. Why, when such a move would clearly only ever be an accident?! And I’m not on board with bowman’s bingo being a method of solving a puzzle when there is no way to write notes to assist with that..Version: 4.16.0

Ad placement lousyFirst, with a couple exceptions I really like the app. It has great features. For the challenge I like to play it with no extra tools or hints that I’ve made a wrong entry. At times I get to the end and there’s a problem I can’t undo easily so I just want to start over. I can’t see how to do that without “un-doing” every move, or selecting each square and hitting erase. Please add a button to clear the puzzle to start over. My second concern is irritating enough to delete the app and find another game. On my IPhone 6s it’s the tight placement of the ad banner next to the number entry at the bottom of the screen. If I play with two hands inevitably I miss the number and hit the ad banner which takes me to another page. I understand the need for ads with a free game. But, that placement is so close that I mistakenly hit the ad many many times during a puzzle and I lose my place or thought process. It is maddening. I don’t even look at the ad, I get frustrated and immediately hit the button to return to sudoku. I’m glad you get the clicks for the advertising revenue but it feels like a setup with the layout so you get those clicks. Please fix these. It would be a 5 Star review otherwise!.Version: 1.1.10

App is excellent except the hint mechanismI’ve been using this app for at least two years (hey, I want that trophy at the end of the month/year!) and it has been appealingly consistent with updates and the ad placement doesn’t bother me in the slightest, mostly because it’s unobtrusive and doesn’t get in the way. Edit 1: Still a great app and I do at least the daily challenge every day, if not more. That being said, with this most recent update (today is 20 May 2021), the style and buttons all changed. Normally this is fine, but in dark mode (which i have to use for my eyes ) where the background is dark grey and the numbers are white and pale blue, this most recent update means that the pencilled in numbers grey out to invisibility instead of highlighting brightly like they used to. Before, when I’d choose a number for final input (where it would go blue and easy to see), every other identical number on the entire board would be bright white. Now, it greys out and it’s impossible to see where matching numbers are across the board..Version: 4.3.0

Best features but latest version is brokeUpdate after developer response: so a working feature that I use was deliberately broken because no one else uses it, so get with the program. Even tho there are multiple reviews complaining about it. OK. Dropping a star and continuing my quest for a replacement. Original review: This version of Sudoku is worth paying the $5 no-ad fee in my opinion - it has the best features and is the easiest layout on the eyes that I have found. However, the latest version (5.1.1) is broken in at least one way - the hints no longer work consistently. Hidden pairs are not seen and asking for a hint after clearing notes once a hidden pair is found results in the game forcing you to add back in the notes you cleared. Asking for a hint at that point gets you a “pick a cell to solve” response, which just puts the correct number in the cell you choose without explaining why it is correct. And maybe it’s just me, but I’m seeing others saying the same thing here in reviews - the new “evil” difficulty level seems to be easier than “expert” on previous versions, as I am solving them much faster than before. I will update this review if things get better, but I’m looking around for another version in the meantime….Version: 5.1.1

Annoying adverts that interfere with the gameAnnoying in-game adverts that interfere with the flow of the game. While the game itself generally works ok, although it can be a bit laggy, the adverts (full page and usually for other games) pause the game until you watch them; some lasting for up to a minute. I’m deleting the app now as I’ve had enough. In a previous review I said “I'd give it more stars (then 3*) if the ads were less obtrusive.” But as I’ve said I’m deleting the app. New app users beware and be warned! A response to my review from the app Development team said you can close adds after 5secs by pressing the “X”. I often tried stabbing at the screen to find a non-existent X to no avail! You often have to “play” the ad game before the X appears, so I’m not convinced the ads do have a 5secs X. It was often up to minute before I could resume the game. I’ll try the app again but I’m still not convinced this issue is a simple as the developer response..Version: 4.12.0

DeletedJust deleted my other sudoku game because they doubled the ads, your app has even more, and I can’t even play at a decent difficulty with having to sit through the beginner levels. Perhaps the ads would be less annoying if they didn’t expect me to interact with them. That’s not your fault, but having to sit through two ads between games and multiple ads during the game is just too much. I’d probably have paid to unlock a ad-free version, but there didn’t seem to be an option. So I’m off to find another game..Version: 5.4.1

DisappointedI love Sudoku; it is one of my favorites and I play it quite a bit from many sources so I thought I would give your app a try. I chose easy for first game to allow me to see how your app operated in terms of filling in the grids. I had a bit of trouble with the game placing numbers in the chosen square; they landed in a square adjacent to where I chose. Quickly the game ended saying I had made three mistakes and game was over. They were not mistakes I made by choosing the wrong square intentionally but rather by a square inadvertently being touched or my not knowing exactly how your game operated. I do not like the feature where the game ends if 3 mistakes are made; especially on the very first game when a player is still trying to understand how your app functions in terms of number placement. In fact, I like to work my sudoku puzzles to completion and if I make an occasional mistake, I like the challenge of finding and fixing it. I do not want the game to kick me out. As a result your app is gone. I have plenty of other sudoku games to play that are both challenging and fun and they do not aggravate me with unnecessary restrictions..Version: 3.9.0

Getting worseI got a reply about the constant adverts popping up during the game. It is a tiny bit better, but still happening all the time. But this morning I was really cross. I had this installation, that I got this three mistakes when I had a number wrong. This morning I thought I was doing quite well, everything worked out until I went with the last two numbers and obviously there was a mistake somewhere and the whole game did not work out. So obviously something has changed as I didn’t get the three wrong attempts. I’m so done with this game. I started to play it in November 2018 and pleaded daily. I think that is to be quite a loyal customer. But I’m thrilled with that. It will be the second game this month that I will delete and not replace. It is annoying and I’m a bit disappointed, but I’m done with it.Version: 4.9.0

Too many lengthy adsFun, but too many lengthy ads interrupt my concentration..Version: 5.5.0

AdsWas so good and didn’t mind the ads but now it’s before and after every game and once or twice just annoying. Have to move to a different app because the ads are on 100% sound. Can’t listen to music and play with them popping up all the time even if you mute it when it starts.Version: 4.14.0

Evil easier than expert :(Hi, this is a good app but why is the evil level easier than the expert level? There are occasionally really hard ‘expert’ ones but these come inconsistently. It would be nice if those ones could be put in ‘evil’ because right now evil is too straightforward..Version: 5.5.1

Spend more time watching ads than playingI’ve never left a review on an app before but the ads are so excessive on this app that I decided to go out of my way to come on the App Store and give it a bad review. Literally spend more time watching ads than you do playing the game..Version: 5.5.0

ConfusionExample today l have completed 3 games on your New games expert grade the first game completed in 6 m 59 second game 2 7 m48 s which was my best time third game 7min1 sec was labeled at better than 93%of other players now how can 7.48be better than the others This is a problem every day explanation please.Version: 4.9.1

My go-to sudoku app, I just wish they got rid of Bowman’s Bingo hintsI got this app a few months ago, having never played before. After playing for countless hours, I’m up to doing the expert puzzles. Much of my strategies have been from methods from the hints. However, sometimes the hint is to use “Bowman’s Bingo” which is basically guess and check, and it’s extremely impractical and rarely used. It gets kind of annoying when I get stuck and get this hint as it makes me feel like some puzzles are impossible without using this method. I’ve asked a few sudoku experts about some of these puzzles and they all have been able to find a much easier technique to solve them (even as simple as a skyscraper). I hope in future updates the app will incorporate more techniques into the hint system and eventually be able to get rid of Bowman’s bingo. Edit: I don’t know when they added this, but there’s now horrendously offbeat music. It’s horrid to listen to and I can’t even focus on the puzzle. Please fix this ASAP!!! And I’ll put my rating back up to 4 stars when you do.Version: 3.3.0

InterruptionOn est interrompu à toutes les 30 secondes par des publicités. C’en est fatigant. Moi je cancelles..Version: 5.5.1

Turn offI enjoy playing a little sudoku to help divert my mind and find a little peace. This version of an artful mind exercising route to tranquility is RUDELY interrupted by loud unrelated advertisements! There’s no setting in which you can turn the annoying sounds OFF unless you turn off the advertisements which is a pay for option. So sorry Developers, any class you gained through pleasant typography and a dark mode is utterly lost in crass kiddie cartoon colour and nasty fake horror scream audio. TURN IT OFF!!!.Version: 1.3.1

Used to be betterThis used to be my favourite app - but the most recent update (with “evil” being a new level) has made all the levels waaay to easy. It used to be a challenge but now it’s not as stimulating..Version: 4.15.0
