May be wonderful, but couldn’t get past two distractions!

Impressed that this developer focuses on pure Sudoku, without ads. His privacy policy is also superb — no data collected. That should be federal law. However, before I could even get started, I encountered two major obstacles! They may not matter to you, so give the app a chance. What were the issues? 1️⃣ An on-screen timer with, apparently, no option to turn it off. That’d a distraction, pure and simple. I play for the intellectual challenge, not as a race. Others must, too. 2️⃣ Several squares that were colored, with no borders. Why? Again, apparently, no option to turn off the coloring and simply see a board. That was also distracting. No doubt, there's a reason for this, but give users the option to skip it! OK, so I figured out it's a focus device. But most of us don't need that! We know how Sudoku works. RECOMMENDATION 3️⃣ A suggestion. My favorite Sudoku game — :) Sudoku (Enjoy Sudoku) is no longer available — but got the design 💯% correct. Two numeric keypads, one to enter the number and the other to pencil in a possibility, was a brilliant design. 4️⃣ In any event, please do not let my review, and my idiosyncrasies, deter you from trying this app. Any developer willing to give to the community, eschew ads, and NOT collect data needs to be given a chance. 5️⃣ Tried it again, but couldn’t figure out how to pencil in possibilities. Then, all of a sudden, the app booted me out of the game, saying I had run out of chances. Whoa, was that off-putting! 6️⃣ Finally, apologies as this review ended up with sentences run together. The App Store review system is broken and dysfunctional. On my iPad and iPhones, I always put in paragraph breaks in my reviews, and they show up on my device, but the App Store consistently removes them and mashes everything together into one MASSIVE paragraph. That’s ridiculous! It's hard to write a coherent, legible review and hard on the readers to process reviews that a mass (mess) of text — and glean the points. This has been going on for years, Fix it, Apple!

Thank you for your thoughtful and detailed review — and for recognizing our ad-free, privacy-focused approach. That truly means a lot.Based on feedback like yours, we’ve made several improvements:• You can now turn off the timer from Game Settings if you prefer a distraction-free experience.• We’ve added a clean black & white theme for a more traditional board look without colored highlights.• We’ve also introduced Number-First Mode, which allows faster multi-cell entry and smoother pencil marking.Regarding chances and pencil marks — the game does support note entry, and we’re continuously improving clarity so these features are easier to discover.We truly appreciate players who take the time to share constructive feedback. If the recent updates address your concerns, we’d be honored to earn that 5th star from you ⭐Thank you again for supporting independent, privacy-respecting apps.

Great App, One Suggestion

This has very quickly turned into my go-to game app. Overall, the developers have done a beautiful job. This app is intuitive, the sudoku puzzles are enjoyable and it's fun to look at the stats and see gradual improvements over time. My only qualm is that I wish that correct answers would lock into place. There have been a fair number of times where I accidentally clicked a correctly filled cell and selected a number intended for the cell above or below causing a mistake to be registered. Using a smaller screened device, this happens enough to cause notable inconvenience. That said, this still knocks every other sudoku app out of the water for me. It has very quickly turned into one of my most used apps. Huge thank you to the developers!

Developer Response
Thank you for the kind words and for taking the time to share such detailed feedback. We're really happy to hear the app has become one of your go-to games — that means a lot to us!Based on feedback like yours, we’ve added a new “Lock Correct Cells” option in the game settings. When this setting is enabled, correctly filled cells are locked so they can’t be accidentally changed. This should help prevent mistakes, especially on smaller screens.We truly appreciate players like you who help us improve the game. If the new feature solves the issue for you, we’d be very grateful if you updated your review — and hopefully gave us that 5th star ⭐.Thanks again for your support!

Undo button is useless
11/30/2025

This is a mobile game. It’s very easy to just accidentally tap the wrong thing. That should be something you can undo with the undo button. But the undo button doesn’t affect notes. Accidentally put a note where you’d put a number you’d figured out? Undo button doesn’t work. Accidentally put a number where you meant to put a note? There go all your notes. If you’d already done any advanced solving techniques, you’re screwed. Might as well give up on the puzzle because you accidentally tapped the wrong thing just once. I’m uninstalling. Maybe I’ll find another app that doesn’t track me, doesn’t require a subscription fee just to play, and actually has a functional undo button.

Developer Response
Thank you for your feedback. We understand how frustrating accidental taps can be, especially on mobile devices.Based on feedback like yours, we improved the system so that both numbers and notes can now be undone, and the undo feature is completely free and unlimited. This means you can safely undo mistakes whether they involve notes or numbers while solving a puzzle.Our goal has always been to keep the game simple, private, and fair for players. If you’re willing to give the latest version another try and the new undo behavior solves the issue, we’d truly appreciate it if you could update your review — and hopefully give us that 5th star ⭐.Thanks for helping us improve the game.
