I've got nearly 1M points in this game. I've been playing it for years, i love that i was able to buy a no ads version. However, it looks like it got a total rewrite. The checking logic has gotten bad. When I'm pencilling things in, sometimes it checks, sometimes it doesn't. it just let me pencil a 4 in a column that already has a 4. It used to clear out pencils where that number was committed in a row or column, but it no longer does that reliably. it's very disappointing.

Good but glitchy. I tried multiple, & what I like about this one is beautiful themes/customization, & an excellent hint system for a little nudge. Importantly, we don't have to watch an ad! But I'm still not satisfied. For whatever reason, I usually have to click SEVERAL times to get the game to register that I'm trying to enter a number (whether entering it directly or adding a note). Literally have to click 5-6x!! This detracts from it being relaxing! This is on a new phone, too. Annoying.

9 April 2025: After installing the mandatory update, there is now a time lag when selecting numbers and the choice appearing on screen. Also, number selections are not always recognized which requires selecting the number again. It slows game play way down. Didn't experience these issues before the update, very irritating. Playing on a Galaxy S24 plus.

I've used this app to play sudoku for a few years now, and it has been a mixed experience. The buttons will randomly decide to be "sticky," meaning you'll click them, and they'll appear to be selected, but they actually aren't. After clicking the same number over and over again for it to actually be selected, it feels pretty obvious that the developers wanted to make the free version as inconvenient as possible. Now, the pregame ads don't have an exit button either! Garbage experience.

The hints on this app are much better than others since they teach you how to solve. I play on expert, and a few years ago, i could solve the puzzles about 60% of the time. And the ones I could not, I could click hint and at least see a pattern that I missed (usually a complex line or a fish). Now I get stuck a lot more, and when I get stuck and click hint, it usually tells me trial and error shows the answer to a square. It was much better when you did not need trial and error.

I played this all the time last year and recently came back to it, and something changed for the worse. I used to love using hints on Expert mode because it showed a detailed breakdown of how to apply advanced methods. However, now whenever I get stuck on an Expert puzzle, 99% of the time the method to use is "trial & error." It used to walk me through exceptionally complex methods, but I have yet to even see an X-Wing come up in the hints. This is very disappointing.
