Thanks ### 5/5 — Fantastic app. *2025-05-21, version 4.54* This is a great app, I use it daily. ### 5/5 — Нормально *2025-05-20* Мастер пропал после определенного кол-ва сеансов, но увеличилась скорость таймера в очень трудных в 2-3 раза. Наверное так задумано? **Developer response:** Здравствуйте, проблема со скоростью все еще наблюдается в последней версии? Мы проведем расследование. ### 5/5 — 2000 and counting *2025-05-16, version 4.54* Love Sudoku I’ve solved over 2000 and going!!! ### 2/5 — Review of Sudoku by Mastersoft *2025-05-15, version 4.54* I wish there was sn expert class to compete in. ### 5/5 — Great sudoku! *2025-04-20* Good to train and develop. You can choose the level of each round and then the app will record your results and levels you completed. ### 5/5 — Sudoku *2025-04-19* Sehr gut ### 5/5 — Bug *2025-04-16, version 4.51* “Hard” level has bug in 7’s making it unsolvable. ### 5/5 — Fantastic! *2025-04-15, version 4.51* Stimulates the mind. ### 5/5 — Very best sudoku online game *2025-01-02* This is the Cadillac of sudoku puzzles. I have been playing this for more than 10 years, and it gives you challenging puzzles, variety in grid and number options, and even the chance to work on sudoku puzzles from your own sources. You can also “rewind” the puzzles, to correct older mistakes. ## Most critical reviews (10 lowest-rated) ### 1/5 — Toolbar is non-responsive *2026-07-23, version 4.67* v4.69 (33) installed on MacOS Ventura yields no response from icons within toolbar below the sudoku puzzle matrix. In game Help and Menu are therefore not accessible. One puzzle can be solve but no further progress is possible after that. ### 1/5 — Sudoku *2026-07-10* I’m mad! I bought the full version years ago and then it was changed and I could no longer do the master level puzzles, now you’ve changed it again and not only can I not do the master level puzzles, but I can’t even do the very hard level puzzles either. Why did I buy it in the first place, and why would I purchase it again if you’re just going to change it again and make me buy it again. It’s criminal! This will be the third time I’ve bought this game! CRIMINAL **Developer response:** Please contact support so that we can get you a full version. ### 1/5 — Sudoku *2025-08-27, version 4.57.01* This sudoku is the best by far. Color coding makes me easy. ### 1/5 — One Game? *2025-05-24, version 4.64* I played and finished one game and can’t get it to do anything else. I clicked on menu beneath the puzzle but it did nothing. ### 1/5 — Game centre not updating score *2025-03-09* I have used this app for many years, almost to an addicted level! 2 current issues. App currently started preventing new games being created & only giving update to pro option. But not actually let you do it and I am convinced I had already done this. App has to be deleted and reloaded to allow further app use. 2nd issue is that even though I am signed in to Game centre and my all time score is displayed when I complete a new game the new score is not being added to the total. Very frustrating and annoying! **Developer response:** Thank you for letting us know. We will fix it. ### 1/5 — Upset *2025-01-01* This was a great game and I’ve had it since my first iPad unfortunately I accidentally updated this app and now there is nothing to play. As usual greed gets in the way of everything. Will be deleting this app now. **Developer response:** Should be okay now. ### 1/5 — Excellent app - was *2024-11-08, version 4.40* This app has proved to be great entertainment and quite a challenge at times. But although I have paid to upgrade it now keeps asking me to upgrade again. ### 1/5 — Sudoku *2024-10-28, version 4.40* I’m mad!

This used to be a great app. Now it is useless. ### 1/5 — The levels have disappeared, only ‘Simple’ shows now. *2024-10-10* I would also like to enter two numbers in one square to keep track of possible entries. my favourite game ## Most praised reviews (10 highest-rated) ### 5/5 — schöner Sudoku löse *2026-07-21* Es gibt, es gibt verschiedenste Vorschläge für Lösungsmöglichkeiten, die man ausprobieren kann. ### 5/5 — Unterhaltsam *2026-07-12* Weiter so ### 5/5 — Five Stars!!!!!! *2026-07-08, version 4.59.01* Excellent!!!!! ### 5/5 — Best Ever *2026-01-22, version 4.57.01* Since iPaq time.
