It is probably really easy to implement this, and would be a great addition. ### 4/5 — 3.1 broke after PadOS 14.2 update, but reinstall fixed it *2020-11-13, version 3.1* This was a decent little app (after glitches a few years ago) until I updated my IPad Pro to OS 14.2 Following the upgrade the app shut down almost immediately. However, deleting the app and then reloading it (and then restoring the payment recorded by Apple) seems to have fixed it. So, one more tiny glitch, but back to being handy for those times when you’re stuck in the middle of nowhere with nothing to occupy your mind. ### 3/5 — Crashes with 14.2 update *2020-11-12* This is my favorite app on my iPad, the only problem is that with the 14.2 u[date the app crashes every time that I try to start it. ### 3/5 — No highlighting *2017-06-25* Without highlighting, this is just another clone. It has a nice clean interface, but lacks features to make it competitive. So many better puzzles out there. ### 2/5 — Can't Delete Now! *2017-05-12* Now can't delete saved puzzles, only save additional ones! Horrible situation! please fix this ASAP. Happened with new version allowing light dark option. ### 3/5 — Don't like the new look *2017-04-29, version 3.0.1* Why did you mess with a good thing? Even now that the numbers are bolder, it was much better before, too much bright white. Still works, I love being able to enter my newspaper puzzle. ### 2/5 — How to mess up an app *2017-04-29, version 3.0.1* The UI is a huge step back. Unreadable and too bright. Please allow the option to change colours or revert UI to what it was. From 5 to 2 stars. ### 5/5 — Hate the new look. *2017-04-28, version 3.0.1* I love the game but hate the new look. Everything is too light to be noticed. The old look was much better to differentiate the status of the cells and their content. Update: thank you for bringing back the readability of the game. ### 3/5 — New look... *2017-04-28, version 3.0.1* The new look is nice a clean, the recent font update is a great improvement, however when selecting a cell the watermark shows through and is very distracting. ### 1/5 — This used to be a great app *2017-04-28, version 3.0* The new interface has very little contrast, so it's very difficult to see the numbers. ## Most critical reviews (10 lowest-rated) ### 1/5 — Problem! *2022-05-25* It freezes when I try to choose a version to play ### 1/5 — Restore old newspaper mode *2022-03-19* Can you please go back to the old method. This new technique is super inefficient. Dont fix what is not broken! ### 1/5 — Latest release newspaper mode is super clumsy to use *2021-12-29* I am a freeloader so I do not have a real right to complain. But I have been using the app for many years and the new interface when in newspaper mode cannot seem to be turned off. Being forced to pick a number in the pad, then tapping it in the grid, forcing me to turn off the number selected in the pad to change to the next number is a terribly inefficient and non-intuitive design. I am not pleased. I hope I can restore to an earlier version. The prior version I would rate a solid 4 plus. ### 1/5 — SudokuTablet *2017-06-07, version 3.1* I like your app but it gives me invalid puzzles. ### 1/5 — Delete No Longer? *2017-05-13* What happened to the edit/delete tool for saved puzzles? Now must just continually add? Pretty ugly!! ### 1/5 — It's Ruined! *2017-05-10, version 3.1* I used to play this all the time but since the latest "updates" it useless. It either cycles through the set up or doesn't respond at all, when it does it has duplicate numbers in adjacent cells and removes numbers when you click on an empty cell. All very disappointing. ### 1/5 — Update stinks! *2017-05-03, version 3.0.1* The new update is very hard on my eyes and i hate it. I played this game all the time and loved it but now its not something i will play very often. Please bring back the original which was much easier to work with. ### 1/5 — Terrible update *2017-04-30, version 3.0.1* This update ruined my favorite game app. Update destroys readability. What were they thinking? ### 1/5 — Unfortunate update *2017-04-30, version 3.0.1* I wish there were some way to return to the former version. The contrast is too high for me to enjoy using this app now. Also, the lack of color makes it more difficult to read. I have enjoyed this app for years, but will now be deleting it due to the changes. ### 1/5 — Update *2017-04-28, version 3.0.1* I hate new update. Hard to see. ## Most praised reviews (10 highest-rated) ### 5/5 — Fun and challenging *2023-11-05* I enjoy the many ways this game can be played. I am not sure what other reviewers had reason to be so negative, tho I do notice most are more than a year old. ### 5/5 — Different levels *2022-05-07* Different levels are available starting easy to tough. 4 different types. ### 5/5 — Wonderful app *2022-04-24* Wonderful app. I like the following. One, I can choose which sudoku game to play. Two, it gives me the option to choose between a dark or light design. ### 5/5 — Great app *2022-04-23* Great app. I like the options to select the level of difficulty and color the wrong numbers red. ### 5/5 — iPhone Version? *2018-03-06* Excellent App. Want to be able to find a version for my iPhone, tough. Is there a version of this App for the phone? ### 5/5 — Thank you for the new update *2017-05-17* The new update is has addressed my complaints. In fact it is now better. ### 5/5 — Dark design returns *2017-05-04, version 3.1* Good. I was disappointed when the 'brown paper' background vanished, but it's back now. ### 5/5 — Classic option restored *2017-05-04* Thank you for listening and restoring the original design. Best sudoku game for iPad or iPhone. ### 5/5 — The white is optional now *2017-05-03* Thanks for allowing the darker background again, much easer on the eyes, once again a wonderful 5 star game. ### 5/5 — Great update *2017-04-29, version 3.0.1* I love the clean simple design. Thanks for making the numbers a bit thicker. Certainly the best program out there to do the newspaper's sudoku. Thank you. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
