We are very glad that you enjoy our app. ### 4/5 — No sounds *2025-08-31, version v3.4.1* No sounds!! I miss the clicks. ### 5/5 — A well-designed app for higher level players *2025-08-10* I lost my long-term sodoku app (Enjoy Sodoku - the one with the Thinker icon) with my recent iPhone update. It took me several days of searching and trying to find this worthy successor. Thank you Logic Wiz! The app has a nicely designed and intuitive user interface with many customization settings, including autopencil, which I use when working tougher grids so I don’t have to grind through that step. The Expert level puzzles require basic “next level” solving methods such as unique rectangles. I’ve not tried the Master level, so I don’t know how complex they can get yet. A true 5/5 app that I was very happy to pay for. **Developer response:** Thank you so much for your review. We are very glad that you enjoy our app. ### 5/5 — Autofill at end *2025-07-24* score would be very close to 5 if an automatic finish was available when most of remaining cells wee naked single and a very small no of cells that would collapse to naked singles as others were solved. I wonder if. It is copyright issue. Still, best one I’ ve found. **Developer response:** Thank you for your review. I'm please you like our app. Automatic finish ( Auto Complete) is available. You can find it in 'Game Settings'. Turn on the 'Auto Complete' slide bar. ### 5/5 — The Best *2025-06-04, version v3.2.14* I am a Sudoku fanatic and this is simply the best sudoku app for iOS/iPadOS that I have come across. ### 4/5 — Level sehr leicht *2025-06-02* Ich mag die App wirklich sehr und finde sie ist gut gestaltet. Es gibt ein gutes Level-Prinzip, Statistiken und Tipps falls man mal nicht weiterkommt. Ich bin gerade Sudoku Anfänger und brauche deshalb die Erklärhilfe. Allerdings finde ich, dass sogar die Experten Sudokus sehr einfach zu lösen Windhund ich habe davor Apps getestet, wo ich es als schwerer empfand (habe mich aber trotzdem bewusst für diese App entschieden wegen den Tipps und der Level-Struktur) Ich fände es cool, wenn die Level ein wenig schwerer gemacht werden könnten und vielleicht sogar ein paar Meisterlevel kostenlos wären. **Developer response:** Thank you for your detailed feedback. We're glad the level structure, statistics and hints have been helpful while you're learning. We've noted your suggestion about harder Expert puzzles and free Master levels. ### 5/5 — Very good app *2025-05-28* No bugs very smooth. Certainly worth the price **Developer response:** Thank you so much for your review. We are very glad that you enjoy our app. ### 5/5 — The best sudoku app *2025-03-12* I have tried many apps, this is with out doubt the best sudoku app. The puzzles are art, the controls are amazing, the hint are actually teach you how to become a better player. You can also learn all the strategies of sudoku. The weekly challenges are very entertaining. **Developer response:** Thank you so much for your review. We are very glad that you enjoy our app. ### 5/5 — Simple and great *2025-02-23* Great app! I find that good level progression is great for someone who has never done sudoku before. On other apps and site I struggled to understand the basics, here I’ve been able to flourish better and gotten a hang of the game. The ads are not very intrusive if you decide to stay on the free version. **Developer response:** Thank you so much for your review. We are very pleased that you enjoy our app. ### 5/5 — Excellent! *2025-02-08* As far as I can tell this seems to be THE sudoku app you’re looking for **Developer response:** Thank you so much for your review. We are very pleased that you enjoy our app. ### 5/5 — the very best sudoku app! *2025-01-31* I was using one that had long ads with pop up's every time i filled a new number, phone would get hot and die fast. this app was recommended highly on Reddit and everyone was right—it’s the best! love the design, the tools and the instructions. highly recommend! **Developer response:** Thank you so much for your review. We are very glad that you enjoy our app. ### 5/5 — Best iPhone Sudoku, hands down! *2025-01-10* Great difficulty levels, great highlighting settings, great help system, but the very best is the candidate handling: mark 2 or more fields, and tapping a number will add/remove it as candidate, this is so fast and actually fun! First iPhone app I paid for! **Developer response:** Thank you so much for your review. We are very pleased that you enjoy our app and thank you for being a premium member. ### 5/5 — Best sudoku app *2024-12-10* Amazing **Developer response:** Thank you so much for your review. We are very glad that you enjoy our app. ### 5/5 — Great features and tips *2024-12-07, version v2.9.3* The features are great, especially the ability to use Apple Pencil and sketch out certain tactics without creating an error. The learning hints are great ways to learn advanced strategies. ## Most critical reviews (10 lowest-rated) ### 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. ### 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. ### 1/5 — Unplayable *2025-12-08, version v3.5.20* Ads don't go away! I have to restart the app. Fix the ads! Horrible! ### 1/5 — Unplayable *2025-11-14, version v3.5.20* Ads now pop up every 15 seconds and I can't play it anymore. Fix the ads! ### 1/5 — New ads make it unplayable *2025-11-14, version v3.5.20* Pop up ads cover ⅔ of the screen and make it unplayable. ### 1/5 — Data mining *2025-09-06, version v3.4.1* I open the app and am immediately asked for my consent to allow hundreds of companies access to my data!! There is no simple way to say no so you have to spend 10+ minutes turning all the ones you can off, be aware there are a number that you cannot disable. It's disgraceful. Any app that tries this hard to scrap your data is bot worthy the risk. ### 1/5 — Game-play itself is OK, but it far exceeds my tolerance for ads *2024-10-19, version v2.9.3* The game-play is decent, but not my favorite. I would have considered paying for the upgrade if the free version hadn’t been so annoying with the ads. I’ll pay for an app if I think it’s good, but, on principle, not just to make it stop ticking me off. ### 1/5 — Way too many ads *2024-02-14, version v2.5.23* The ads in this app are ridiculous. You start a new sudoku, you get an ad. You auto fill the candidate pencil marks, you get an ad. You start a new sudoku, another ad. It’s insulting ### 2/5 — Ads are fine, malicious pop-ups go too far *2023-11-12, version v2.2.55* I understand that as a free app user I should expect ads. While somewhat pervasive they had not gotten in the way of enjoying the game. More recently there is a repeated pop up in Safari leading to a malicious site that is designed to look like Amazon. That goes too far for me. I am removing this app. ### 2/5 — Ads need to be fixed *2023-11-10, version v2.2.55* Awesome app all around. Been using it for a about a week. Now when I choose a hint, an ad pops up. Not a problem, but it’s never ending. No ability to skip or close out and it just continues from ad to ad. Force closing does not work as it just comes back. ## Most praised reviews (10 highest-rated) ### 5/5 — Love the new look Amazing *2026-08-04* 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 **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. ### 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 ### 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. ### 5/5 — Ads cover game! *2025-11-14* I understand that ads are the way to make money but these are too aggressive. I’m filling in a puzzle and an ad will cover half the screen. It used to cut to an ad once in a while but now I spend half the time closing ads so I can see the puzzle. **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 — Others *2025-10-16, version v3.5.6* The other Sudoku games don’t even compare to the thoughtful design of this one. Love it. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
