Irritatingly poor interface

I loaded, tried, and deleted. Compared to other Sudoku apps I find this user interface to be downright irritating. So who knows; if you think the way this programmer does then you will like it. Otherwise just delete it and move on.

Fun game!!

I had never played sudoku before but I found this game really fun and it’s a really good puzzle game! I recommend this to anyone who gets bored really easily, likes puzzles and is generally creative! My only issue is that there probably should have been a tutorial screen as the controls can be a bit confusing but you’ll get used to them..
