You can’t pick up at the last puzzle you finished. There’s 2k puzzles but you really have to start at #1 every single time you open the app. Worst of all the update deleted all of your progress. ### 1/5 — Just bad - too simple *2019-11-19* Bad app - no undo, no hint, no number highlighting ### 1/5 — No save function *2018-09-15, version 3.0* Can’t save game progress which makes this app completely useless. ### 1/5 — Can’t win *2018-04-06* I tried four different puzzles and they all ended in errors, not by user error. Even before you start the puzzle, the verification button results in error. ### 1/5 — Not fun *2017-08-20* No way to pencil in numbers or change difficulty levels. I am deleting this app. ### 1/5 — Needs work *2016-09-02* The app does not save your progress, it also needs the ability to pencil in the smaller numbers. ### 1/5 — Very disappointed *2016-08-08* The puzzles are nice but you have to complete the whole puzzle in one sitting. If you leave the app and come back all of your progress is erased. ### 1/5 — D: Real shame... *2014-07-01* This was my favorite sudoku apps, but with the update, it is lacking. Ads are so annoying, on top of a app that crashes after completing one puzzle? And then it doesn't open period. Other thing is that I wish I could used the app in portrait or landscape mode not locked to portrait. I really hope this gets fixed!!! ### 1/5 — Horrible update! *2014-06-28* Oh no! My fav game is ruined. No more landscape orientation? Really? Goodbye, old fav :-( ## Most praised reviews (10 highest-rated) ### 5/5 — A wonderful challenge! *2024-09-01, version 3.2* I love having the 16 squares to work with. I also was surprised by having to fill in all the squares before you can use the verify button, but I like it. There are no hints. No helping you along. It’s become my favourite, most frequently used puzzle. I’ve solved so many puzzles that I’m absolutely confident that they all have a solution. I sometimes have to start over with a puzzle but it’s so satisfying when I do finally succeed. ### 5/5 — Love it! *2022-08-22, version 3.0* I’ve solved every one I’ve tried, but often need to do some guessing by the end. It’s true that you get Incorrect if you push the Verify button before all squares are filled in - you can’t check your progress. That just makes it more challenging though. Recommend this app to anyone who wants a tougher, more time consuming puzzle. ### 5/5 — Sudoku *2013-03-21, version 1.0.1* I like the challenging aspect of the 16 x 16 as opposed to the typical 9 x 9 games. I recommend this to everyone . ### 4/5 — Problem *2022-12-30* The game doesn’t stay open and kick me out. Since the version 16 update. ### 3/5 — Clears progress unexpectedly *2017-03-20* Interesting variation of Sudoku...but confirmed the game clears any partial progress after awhile...even if left Open in the background!! No Save feature either. But free, so mid range rating. Deleting it though; impossible in one sitting. ### 3/5 — Locks Up *2014-03-01* Game 37 can't be finished. Main window opens to black but restores to a screen where touches don't work and the app quits. Great up to this point, however, but real Sudoku puzzles have only one solution and the games numbered over 30 appear to have more than one. Can't wait for version 2! ### 3/5 — Keeps Crashing *2012-11-11* I love these puzzles but after I play somewhere between 5-7 games, it wont start up the next time I want to play. I have to re-download to play... Very frustrating. I am playing on Ipad2 with most recent operating system.... Please fix!!!!!! I have done 20 puzzles and this is the 4th time I've downloaded...THX Would give five stars if it didn't crash ### 2/5 — So limited *2019-02-27* No way to pencil in numbers, and since puzzles are computer generated, there’s no rating for difficulty. Basically, it’s a bummer. ### 2/5 — No pencil option *2017-11-21, version 3.0* Missing the pencil option most Sudoku have. Puzzles are too easy. Not enjoyable. ### 2/5 — Unable to save progress *2017-09-22* Love the puzzles but need to be able to save a partial puzzle of work already entered. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
