Good Sudoku by Zach Gage

The app pretty much functions as intended, there are ads which can be annoying but it’s to an acceptable degree. What really grates on my nerves while playing is that the background music can be super buggy. It sometimes will play the music for the game selection screen, but when you start playing a puzzle the music will cut out, or it will work fine but then cut out after an ad plays, or it will be silent but will come on for a few seconds and be silent again, and sometimes it will play both the music for the game selection screen as well as for the puzzle at the same time. I have to close and reopen the game multiple times to try to fix it but sometimes this doesn’t work either. This was not really an issue at first but has gotten so persistent to the point that I now avoid playing the game because it’s so frustrating. Still, it’s otherwise a decent app so I don’t have much else to complain about. For me personally though, this may be enough to drive me to uninstall it altogether. Also, I wish there was some kind of dark mode that wasn’t locked behind a paywall, because it honestly hurts my eyes & I hate the color palette, but I’m not willing to spend money just to change that. I’d rather just not play it. But that’s just me.

UPDATE: I messed around with the settings and disabled most of the hand-holding things I disliked. The level of customization is really amazing. Changed from 3 stars to 4 stars. User interface takes a little to get used to, but is pretty good. OLD REVIEW: I could see how this would be helpful for someone learning how to play sudoku, but as someone who’s used to pen and paper, this seems too easy. You can tap on the numbers to show you what squares could possibly be that number, which takes away the “aha!” moment from me and just makes me feel like the computer is doing all the work. Add that to the auto-enabled “feature” that only lets you put a note of a number if it’s possible with your current. Board state. Sounds good at first, but it takes most of the fun out of it for me. Could be good for others, but way to many crutch features for me.

Hi Zach and Jack, I hope you guys read these reviews. I’m a sudoku junkie and you fellas have yourselves a very nice little app here. I have 2 issues to report, one, kind of a big deal, the other not so much. The one that’s not a huge issue is a graphical issue: on phones that have the notch at the top of the screen like the iPhone X, Xs and 11, there is a graphical glitch that makes the “horns” of the screen white while the rest of it yellow. Now the 2nd issue: related to the Techniques functionality. When browsing a given technique, and then clicking Hint to get more info about the technique, you’re then given an option of Show Me. The issue is that when you click Show Me, there is hardly any time (about a split second) to see what the system is showing you. Almost immediately after clicking show me, the screen gets covered by another dialog box and it’s only options are to go back to the main menu, or try another example. For people to be able to learn, the screen that results from pressing Show Me needs to persist for as long as the user needs it, and further, you should be able to toggle back and forth between the before and after of the number changes. This is the other Sudoku apps do it. Great work so far and hope to see that update soon!
