This is a new app for me. ### 3/5 — Very good but… *2025-04-08* When you make a mistake and put a false number, all the marks you have made are erased, and can’t be recovered, even when stepping backward. ### 4/5 — Kamil *2025-01-05, version 5.18.2.0* M ### 4/5 — bug 卡顿 *2024-06-22, version 5.17.2* 玩几年了，该修复bug了，现在卡的不能玩了。ios 17.5.1。 何时才能修复？现在根本没法玩…. 不是卡就是被强退😢 ### 4/5 — Muito bom *2024-04-07* O jogo e muito bom ### 3/5 — Freezings *2024-03-25* The game sometimes freezes for a 10-20 secs ### 5/5 — Fun *2024-02-23* This version for iPad is extremely useful. While recuperating from surgery and on heavy pain meds, Soduko helped me to focus my concentration and shortened my recovery. ### 5/5 — Top *2024-02-07* kaum Werbung, technisch gut ### 4/5 — Version 5.17.2 *2024-01-06* I had been very happy with this app. However recently it started to freeze after a few seconds. Even with this update the sudoku continues to freeze on my iPhone 12. ### 4/5 — Top hyper satisfaisant *2023-12-18* Juste super. Un jeu qui donne entière satisfaction si vous aimez les chiffres ### 5/5 — Sudoku Word-Brainstorming!! *2023-12-17, version 5.16.1* Super ### 5/5 — Super *2023-11-25* Ich habe noch die alte Version und die ist gut und nicht verbesserungswürdig! Never change a running system! ### 5/5 — Can’t save your game in the middle *2023-10-02* Difficulty levels are good but the only drawback is that you can’t save your game and start again from same place. It always begins from start, which is very frustrating. ### 5/5 — Great ! *2023-04-11, version 5.16.1* Just love it! ### 5/5 — Excellent game that doesn’t jam ads down your throat *2023-02-02, version 5.14* Yup! ### 5/5 — Best sudoku on the web *2022-11-04* This is both offering most forms of sudoku wit, jigsaw, classic, X, super and samurai it’s easy to operate as well. ### 5/5 — Has all features I want! *2022-10-21* I wanted a sudoku that had 16x16 plus all the other types of sudoku. I like that I select the levels I feel like playing at the moment. It also gives me the option of receiving reminders for the daily game. Plus they have bonus games at all times. Complete sudoku package! ## Most critical reviews (10 lowest-rated) ### 1/5 — It constantly freezes *2024-05-28* This game was great when I got it for the 16 x 16 sudoku. But for the last few months it freezes for about 5 mins everytime it restarts. Now it's freezing whenever it wants too. I got on the ad in the app store to report a problem but that won't let me continue past selecting the issue. When I try to go to the developer site it just opens Facebook to my feed. This seems to be the only way to tell someone (hopefully) about my issue and GET IT FIXED! Help! **Developer response:** Hi, Thank you for the feedback. Would you please let us know what is the device and iOS version you play on it? ### 1/5 — Much better, but... *2023-11-12, version 5.16.1* This app is terrible. It continues to freeze up on me, the app suddenly closes while I’m playing a game (and often deletes the current game) and now I have a screenshot of a game that refuses to accept the correct number ### 1/5 — Cannot delete *2023-01-01, version 5.8* I have this game on an old iPad 2. It won't load and I can't delete it! ### 1/5 — Much better, but... *2022-08-11, version 5.14* This app is terrible. It continues to freeze up on me, the app suddenly closes while I’m playing a game (and often deletes the current game) and now I have a screenshot of a game that refuses to accept the correct number ### 1/5 — Not user friendly *2021-04-03* I work quickly when doing a sudoku puzzle and this game doesn’t allow for you to quickly review numbers and turn on and off notes. This wasn’t enjoyable to play. ### 1/5 — Glitchy game *2020-03-13* There are times when I’m zoomed in on a samurai sudoku and it keeps zooming out when ever I press a number to highlight that number. Though I love that game I’m defeating because of this glitch. ### 1/5 — Mieses Spiel *2019-08-12* Schlechtestes Spiel ever!! Bei jedem anderen Spiel gleicht sich Glück und Pech bei falsch gewählten Lösungen aus! Bei diesem Spiel nicht!! Ein Schelm wer schlechtes dabei denkt, so wie ich!!! ### 1/5 — Keeps kicking me out after last update !! *2019-03-26, version 5.6* please fix ### 1/5 — Updated today *2017-05-12, version 5.1.0* Update to review: Now working. Features I loved are back. One issue still - the auto fill does not update (remove the numbers as they are used). Original review: Hoping that all the features I loved would return -- this edition won't open. Using on IPad. ### 1/5 — Crap *2017-05-10* Doesn't run anymore since last updates under iOS 9.3.5 ## Most praised reviews (10 highest-rated) ### 5/5 — Constant freezing. Wont respond to touch. *2025-10-13* I really hate to leave a negative review. My husband and I enjoy this game very much. We play it on his iPad regularly. It works perfectly on his. But, for some reason on my iPad and my phone this game keeps freezing up. It will let me put in a few numbers and then it won’t respond to touch anymore. It’s very frustrating. I wish there was some fix for this. But there’s no means of communicating with the makers of this game that I know of. ### 5/5 — Great Game *2025-10-08* The only problem is they don’t have an auto finish ### 5/5 — Helpful *2025-08-12* I love sudoku , when you put a number in the wrong place, the number turns red so you know it , so you can just put a number on whatever place and you just do it until you get it right, I have been using this as an average, it also has a mark which is a pencil and two pluses , if you press it, it shows you the choices of each square so you can just put the numbers it shows and finish another game, it also has different levels to suit you , its really fun so five stars. ### 5/5 — Great app *2025-04-17, version 5.18.2.0* Zero complaints. Solid and great challenge. Good for your brain health. ### 5/5 — Sudoku *2025-03-12* I’ve been doing these puzzles for years now. And I still enjoy working them out. Got to keep them brain cells working. ### 5/5 — Mrs.El *2024-09-24, version 5.17.2* A very good game, interesting and challenging. ### 5/5 — The Pumpkinpie-KittyCats a greatful customer *2024-06-10* I have always loved sudoku of every type And now especially this application style and expansive options of all types and ways my thanks to this company! ### 5/5 — The Pumpkinpie-KittyCats a greatful customer *2024-05-02* I have always loved sudoku of every type And now especially this application style and expansive options of all types and ways my thanks to this company! ### 5/5 — The Pumpkinpie-KittyCats a greatful customer *2024-04-26* I have always loved sudoku of every type And now especially this application style and expansive options of all types and ways my thanks to this company! ### 5/5 — Fun *2024-04-07, version 5.17.2* Great game!
