Excellent controls for entering numbers in the way you want. Puzzles are properly formatted (symmetrical) unlike so many other games available. Love this! *** notice, when opening the app, there is a notification coming up saying you need to install the new version. Pretty sure that it's spam.

The "search" button is too close to number 9, end up clicking it by mistake and it ruins the entire experience because it shows ir highlights mistakes I.e. gives the wrong answers when I'm trying to solve the game myself. Especially hard and above. It should be placed elsewhere other I can just get another Sudoko that won't reveal answers to me and deny me using my brain. Not sure why it's there to begin with. (Memo) one should either be able to solve or not without solutions or mistakes.

Perfect app except for a few bugs: - Sound is set to off, yet everytime I restart the app the sounds are playing. In the settings, they are still off... In the dark theme the sudoku board is much darker than the rest of the app, almost invisible - it's unplayable this way... Thank you for your response!
