Great port of Sudoku! I am not being bombarded with ads or fake clicks which is an issue i found on other apps. I really enjoy the helper setting and other personalizations as I am a beginner at Sudoku and it's helping me learn much quicker. I'm grateful for the different level challenges too. I only wish there was a setting to turn off (or maybe make invisible) the timer, as I like to play casually not competitively. Though, maybe the setting is there and I've missed it.

Sometimes the game squares opens in a smaller window similar to 1 handed version of the phones regular screen. But it is not in that mode. The touch doesn't line up with the smaller version. I have to guess where to hit yes to exit. I doesn't do it all the time but when it does it will never open full screen again. I uninstall and reinstall until it does it again. It only started doing this 4 to 6 months ago. Samsung S20 Feb

Hi! Thanks for your feedback, and sorry to hear that you are experiencing issues. But issues you have aren't related to any specific application, and most likely to AMOLED display and how you use your device (brightness, screen timeout, light modes etc), I would suggest you to check more about why and how it is happening to prevent that. Regards.

The only thing I don't like is if you exit out of game or take a break, you can't go back and finish it. It'd be helpful to be able to change color pallet fir the numbers during note writing. Thanks
