Not many apps are consistently updating their app I have all the sudoku apps and I enjoy playing daily. I’ve managed to go from beginner to master in regular sudoku. I look forward to new updates for puzzles and I’ve been hoping for themes, especially the new purple. Thank you so much **Developer response:** Thank you so much for your review. We really appreciate the feedback and your kind words. ### 5/5 — Highly recommend! *2026-06-27* Like another reviewer mentioned, I was a long time Enjoy Sudoku user and needed a replacement after it stopped being available. This app is pretty much perfect. Dual number pads, highlighting for easier pattern recognition, cross platform sync (!) and buy once to play on every platform (!!!). Only small complaint is I wish there was a way to draw filled in rectangles when highlighting candidates but the normal cell highlighting does mostly what I need anyways. I like that you can buy the unbundled or bundled games and they have the same interface and engine. If you're picky like me and find 99% of sudoku apps to be trash then try this one. **Developer response:** Thank you so much for this wonderful review. We're very glad the dual number pads, highlighting, and cross-platform sync have worked well for you. Thank you also for the suggestion about filled rectangle highlighting, we've noted it. ### 5/5 — Most Flexible Options *2026-05-04* Love this version of Sudoku. I have been able to set it up the way I like and have tried different settings outside of my comfort zone that have actually helped me explore new ways to play. The hints are very helpful to learn more complex moves. Love the ability to select multiple boxes, undo AND redo, etc. Overall, my favorite sudoku app that I found through MANY different options. **Developer response:** Thank you so much for the wonderful 5-star review. We’re really happy to hear that you’re enjoying the app. ### 5/5 — Great App - Great Customer Service *2026-04-14* I had a Sudoku app (Sudoku+ released in 2008), for more than 15 years, playing over 2000 games. I upgraded my phone in May 2025. When I upgraded my phone, I found my app had been discontinued. I tried unsuccessful to get it back. I started a search for a new app. I tried 23 different apps. None of them are even close to having all the features in my app. Until I found, Logic Wiz Classic Sudoku. This app had more features and tools than my previous app that was discontinued. Except for one that I liked. When a digit was selected, it was highlighted. As soon as you select coloring mode, the digit was no longer highlighted. I sent a note to the developers. Approximately two weeks later, THE FEATURE WAS ADDED. This app has all the features as my previous, plus a few more. **Developer response:** Thank you so much for the wonderful 5-star review! We’re really happy to hear that you’re enjoying the app. ### 5/5 — Great game *2026-04-05, version v4.0.25* I have played many different Sudoku games. This is the best and it’s worth the price. ### 1/5 — Horrible interface *2026-03-31* The clean and elegant lines of the previous interface have gone - replaced by busy colours and backgrounds . Hate it. **Developer response:** Thank you for your feedback. To revert to puzzle interface similar to the previous version, please download the most recent update and follow the next 2 steps: 1. Turn On: 'Game Settings'=> 'Legacy Keypad'. 2. Turn OFF: 'Game Settings'=> 'Show Keypad Tabs'. I hope this helps. ### 5/5 — Great new interface! *2026-03-27* I’ve been playing all your games for some time. I love the recent changes to the interface! 😁 **Developer response:** Thank you so much for your review. We really appreciate it. ### 5/5 — Love the new look Amazing *2026-03-27, version v4.0.12* I’ve reviewed this game a few times since it first came out and have never had a bad thing to say. Not many apps are consistently updating their app I have all the sudoku apps and I enjoy playing daily. I’ve managed to go from beginner to master in regular sudoku. I look forward to new updates for puzzles and I’ve been hoping for themes, especially the new purple. Thank you so much ### 1/5 — Unplayable *2026-02-11* Ads don't go away! They open up Amazon store. The last over a minute with no way to stop them. Sometimes I have to restart the app. Fix the ads! Horrible! **Developer response:** Thank you for your review. We haven't change anything with our Ads. We have received few complains about this type of ads and approached all our Ad vendors to stopped showing this type of Ads in our app. I believe the problem is solved now. Please let us know if it isn't. ### 5/5 — Wonderful *2025-12-18* An excellent app to help learning to solve sudokus. **Developer response:** Thank you so much for your review. We are very glad that you enjoy our app. ## Frequently asked questions about Sudoku Classic ### What is Sudoku by Logic Wiz?
