Classic Sudoku! for Negative User Reviews

✓ Battery hogAbsolutely kills battery life on IPad Pro!.TdbiiiVersion: 1.01

✓ Good puzzles, problematic functionI love watching the Cracking the Cryptic YouTube channel so I had high hopes for this app. However I have had nothing but trouble with it! First, the code to supposedly transfer the app data from one device to another does absolutely nothing. I started a puzzle on one device but can’t continue on my other device. Also on several puzzles, the hints were completely wrong. One hint said that R8c9 was a 1, but the puzzle already had a 2 in that square to begin with… Also sometimes the pencil markings don’t allow both the centre numbers and corner numbers, they just switch all the marks to one or the other. Overall, pretty disappointing..BallerinadanceVersion: 2.1

✓ Good puzzles but too many locked puzzlesEnjoyable puzzles so far — I especially liked the initial hint after the first game, and hoped there might be more after each game, but not yet. I am disappointed that, with a paid game, I must (I assume) work my way through the easier puzzles to get to the “locked” ones. I would rather attempt some of the more challenging ones. I don’t want to play a game that feels like busywork! Oh, I forgot to say that the notation features are terrific — fairly intuitive (except perhaps for how to “get out” of the multiple selection tool) — and clearly made by puzzle-solvers. Other popular apps don’t have nearly so many tools that allow you to use your own notation style..Nico-suaveVersion: 2.0

✓ Save your moneySome of the puzzles have incorrect hints associated with them. They are all ultra-hard and sometimes you can spend hours and hours looking for a solution that just isn’t there and only can you make progress by guessing. The functionality is absolutely fantastic, but due to incorrect hints and getting stuck on puzzles with no chance of making progress without guessing I can only give one star. I cannot justify $5 for this app. This would be better if all of the sudoku apps by cracking the cryptic were combined into one. Then I could justify $5. Maybe if they updated it and added more puzzles then I could also justify the $5. It’s just a waste and I’m sorry I blew $5 on this. I will add it seems only the cracking the cryptic puzzles seem to be flawed, the other writers puzzles are fun and solvable..Steve.kcVersion: 2.1

✓ Good puzzles but could improve hintsI find the puzzles nice but I bought the app hoping it would teach me some advanced logic solving more than it does. There are no tutorials on what X wings or other solves actually look like. I was hoping that the hints would be a bit more relevant plus the hint box is right in the way. For instance it has told me there’s a triple which I’ve annotated already but won’t tell me why that’s helpful. I often have to use more than 1 hint. Maybe it’s set for some one more ahead in their sudoku game than me. One or 2 optional ‘practice’ puzzles which have annotated advanced techniques would improve it for me..Peagreenboat167Version: 1.07

✓ You are only paying for 100 puzzlesPurchased thinking more puzzles will be eventually added… NOPE!!!.DGmissbumpVersion: 2.1

✓ GlitchyPuzzle 9 has multiple working answers but will only complete if given the correct answer. This is the problem with handmade sudoku. Can provide photos as evidence.FlabradoodelVersion: 1.07

✓ Need moreI think the games are some of the best out there. And the actual design and usability are great. However, aside from a couple of niggles that others have mentioned, my problem is that when I paid for the app I understood we’d be getting five new puzzles each month. It looks that’s happened until this month. We’re now on the August 16th and no new puzzles. What’s going on?.@josephhugVersion: 1.08

✓ Good Game a little frustrating.I like the game but I find the hints very frustrating. They are either wildly wrong, often contradicting the given numbers or require reasoning that if you possessed you obviously wouldn’t require the hint..Bright_waterVersion: 2.1

✓ Great app, but the hints aren’t greatHonestly the puzzles are great and a ton of fun to solve, but the puzzles are hard so a beginner like me needs a few hints. Some hints are great and help you progress the puzzle or show you a technique to advance your skill, but others tell you things you’ve already done or things that help narrow down options but don't actually progress the puzzle. In one or two cases Ive seen the hints just be completely incorrect as well..HeyitsyanoyVersion: 1.07

✓ Not entirely what I had expectedI frequently visit the Crack The Cryptic site on YouTube. On the back of Simon’s recommendation I thought I’d try this app. Most of the puzzles I get. But the more complex ones from which I had hoped to learn advanced techniques remain a mystery to me. The Hints are helpful in the main but due to size limitations in the dropdown box fail to adequately explain the logic leading to a specific number being placed in a square. In addition I find I have to keep switching between the Hint box and the puzzle to try to understand the solution. The puzzles are certainly more challenging than your average Sudoku app but the abridged nature of the hints leaves me none the wiser when it comes to solving the more complex ones..NidostarVersion: 1.07

✓ FantasticThis is the best sudoku app I’ve found. I consider myself an intermediate solver, often stumped by the harder sudoku puzzles. I love that the difficulty of each puzzle builds nicely off the previous ones, slowly incorporating more advanced logic techniques. For example, I am about a third of the way through the puzzles and was just stumped; however, I was able to use the “hint” button to explain to me the y-wing logic needed to complete the puzzle. Hopefully, I won’t miss the next one! I love that the app is challenging and helping me to improve. The user interface is well done. I highly recommend this app..Gigantor2100Version: 1.01

✓ Serious quality issuesGiven the level Cracking the Cryptic operates, I would expect a higher degree of care put on the puzzles and hints on how to solve. Puzzle #60 is not unique. Reading other puzzles are also not unique. As mentioned by others, many of the hints are incorrect as well. The app is great. The puzzles are what we’re here for, however..The A DudeVersion: 2.1

✓ Don’t bother with the hintsThe game itself is great; a very nice setup for everything. And the landscape orientation in the latest update is great. However, the difficulty of the puzzles skyrockets after just a couple puzzles. And the “hints” they give you RARELY do any good. Either it’s something blatantly obvious that you already have, or it’s incredibly vague like “the options in row 6 should help.” (An actual “hint” I got). If you’re not already an expert at soduko, this might be a very frustrating app that leads you to just guessing, which defeats the purpose of the game..Anonymous1776Version: 1.07

✓ Great puzzles, but coloring of squares really confusingI love this curated list of puzzles, but the UI for coloring of squares is extremely confusing (or buggy). I am able to solve complicated sudoku puzzles, but I really struggle with how to, for example, mark these three squares in yellow, and these other four in blue. Everything else in this UI is relatively intuitive, but not the coloring of squares. Just the UI for picking a color is weird. I should be able to tap on the three colored circles on the left to change color, but nine times out of ten, it doesn’t change color. (And it has white outline around two colors ... what does that mean?!?) And even when I have a color selected, for the life of me I can’t consistently say “ok, make these three squares yellow.” Other than that, the game is great, but this feature makes it super annoying, should one want to color squares....Robert RyanVersion: 2.0

✓ Very buggy on iOS. Ok on iPadOSToo many bugs. Unsolvable puzzles where the only number missing in a box doesn’t fit. I’ve run into this on multiple puzzles but didn’t have the same issue on the iPad. Just iPhone. Also on iPhone the numbers don’t gray out once you’ve filled in every grid with that number. Again this works on iPad. Not sure why it doesn’t come across on iPhone..EastSideHornsVersion: 1.08

✓ Love the software But.... NEED MORE PUZZLES !!!Love this software it’s awesome, really helps on solving the puzzles. The only downside is once you have solved all the supplied puzzles and at least half are too easy, the software is completely useless without more new puzzles or the ability to upload other puzzles either by manual entry or from photo..Wattsy99Version: 2.0

✓ Mostly GoodThe app itself is very functional and the puzzles are interesting. The problem with this app is that some of the puzzles are unsolvable and the hints that are included with those puzzles are incorrect. They seem like they might refer to other puzzles or simply don’t take the actual board state into account. If this problem was fixed, the app would rate a 5..VirginiaGamerVersion: 1.09

✓ Lacks polishThe app lacks a lot of polish, I would not recommend it. Hints, which are meant to teach you more, use shorthand which is not explained anywhere. They don’t even just highlight on the board, instead they cover it up so you have to remember what it says OR keep flipping between the board and the hint. And often times the hint assumes you were able to get to a certain point in the puzzle, so it might not even help. Other apps can give you a hint based on the current position in the solution where you are at. The text for instructions is too large and does not respect the default text size on the phone and the scrolling is wrong (does not behave like other windows on the phone). There is no pause button if you need to step away for a few minutes, you have to exit the puzzle. The numbers to select are smaller tap areas and feel like they are an after thought in the design. There are multiple ways to mark the puzzle and the description for how to use them talks as if you know a lot about Sudoku. Overall, does not feel like an app built for iOS and definitely not for beginners..Ryanjm33Version: 1.08

✓ Terrible controls!The controls are terrible. It took me the better part of 5 minutes to even get it to let me enter a firm number, not a pencil mark. Even after re-reading the instructions, I can only reliably get it to take entries if I don’t switch between options. Also after any touch of the color choice highlight tool, it simply will not let me enter anything into the boxes unless I go back to the highlight tool and toggle it around to regain any ability to continue the puzzle. I’m not sure how the 5 star reviews got here as I can’t even reliably get numbers entered into the grid..Kai-FengVersion: 1.01

✓ Bad hintsThe annotation features are top notch, but the hints are difficult to process and—at least for level 16—wrong. It says a pair in one row constricts an unrelated value in a different row. Having solved it now, I understand why the hint made no sense, that’s not where the 9 goes. It would be nice not to have the hint block the puzzle and to be more graphical, not textual (maybe then they would have caught the error in hint 1). The text in general in the app is HUGE..Daryl ZeroVersion: 1.07

✓ No more new puzzles?Good app with excellent puzzles but the updates stopped 5 months ago. I bought this app on the understanding that there would be 5 new puzzles each month, they stopped at 100. Such a shame, would not have minded buying the app if I had known this and could have made an informed decision. Now playing other sudoku app with daily challenge which is great..Pav_cVersion: 2.1

✓ A few tweaks neededOne you close an unfinished puzzle there is no way to find which one you were just working on without searching all to find it! Hints in middle of puzzle so can’t refer to grid as the hint gets in the way.SleepymonsterVersion: 1.08
