Some sites automatically increase difficulty based on how much you play. On this site, I can play any time and as many times a day as I’d like at whatever level I want at that time.

So if you’ve ever copied or cut from safari or anywhere, the app pastes that each time you open it. Whatever you have copied or cut last. Be it passwords, credit cards, etc. There is no way to revoke the apps permission to do this. It’s unfortunate because I paid 99 cents to unlock ad free. ### 2/5 — didn't have the feature I needed *2018-01-19* I will only play sudoku if the game has a feature that fills in the notes automatically when turned on. I'm not going to go through by hand and fill them all in before I play. Not when the app should be able do that part for me. Nothing I tried produced that result for me, so I deleted this right away. ### 3/5 — Cuz *2023-11-21, version 1.7* Color is annoying ### 3/5 — New game *2020-06-05, version 1.7* I am used to a different sudoku game. I need to get used to this one. ### 3/5 — Soduko *2019-09-01, version 1.7* Trying it out. Easy first game for learning. Used the show error button to assist. ### 3/5 — May Be Good, Ads Are Abusive *2016-11-21* I only played for a few minutes before the constant ads drove me away. I love Sudoku, but not enough to pay this price when excellent play is available elsewhere for a good price, even for free. **Developer response:** Hi Geekausaurus, thanks for your review.

Happy Solving! ### 4/5 — Fun and minimal ads *2024-12-23* Love the different modes: easy, medium, hard and expert. Saves paper and erasers! Really enjoyable. Sudoku doesn’t evolve math, there is no adding or subtracting. If you haven’t played it yet and love puzzles, give it a try. This game makes filling in and deleting candidates so easy. I love how when you select a number, all those numbers highlight so it’s easy to see. Very enjoyable interface. ### 4/5 — Good one *2021-08-21, version 1.7* There are so many different sudoku apps it’s very time consuming but this one is one of the good ones.. Trace ### 4/5 — PennyDellSudoku *2020-07-01, version 1.7* Your constant long ads kept you from earning five stars ### 4/5 — Different sequence *2020-03-22* I really enjoy sudoku, especially ones in which you can set a level of difficulty. This one does that well. The problem I have is with the sequence of inputting the digits. All of the other 4 sudokus I work on inputs the blank space followed by the number. In this version, you must first tap the number, then the corresponding space. When it’s done in the wrong order, it results in an error. It’s a good challenge and keeps my brain hopping! I think it adds to the brain connections being built. If the sequence could be the same as all of the others I have seen, it would have gotten 5 stars. ## Most praised reviews (10 highest-rated) ### 5/5 — Love this game *2026-03-13, version 1.7* Always loved sudoku ### 5/5 — Great game! *2025-09-29* Best site for playing sudoku.
