Response from developer

Hi thank you for your review and for using my game. I fixed the bug in version 5.17.

Outstanding accessibility!

This app works great with VoiceOver and my braille display. I like how it notes "given" or "conflict" next to a number, rather than depending on the color of the number to communicate its status. The only suggestion I have is to make the announcement that it is solved automatic, as soon as the final number is in place. The only way I have found to confirm it is by tapping one of the numbers below the board.

Too many bugs for voiceover users.

Etc.

sudoku is one of my favorite solo games. This one is particularly nice. It's easier on the eyes than most and is straight forward in how it works.
