Great looking, sleek Sudok with no ads. The difficulties in this game are harder than in other games, at least in my experience, as I actually had to learn some more advanced Sudoku tactics to solve a board. 5/5 with one minor complaint/feature suggestion: After filling in notes on the board and then writing a number, the notes that cannot be true anymore are not automatically removed. While this is not a necessary feature, it would be nice if this was implemented.

This is much the best sudoku, I have found. No annoying ads, no silly gimmicks just Sudoku with notes possible and lots of levels of game. Just one fault: I found the background far too light, and the figures a bit too small for me. There needs to be more contrast between the notes and correct figures. But I think this game much better than others I've tried.

Like that you can set up your own puzzles. will use this due to this feature since most apps don't have this. Wish the undo button would undo the note numbers you put in, instead of just undoing the solved numbers. Also, when leaving the app and returning without closing, it saves my created game but not the penciled in numbers-- which is a bigger pain,l. I can't leave a puzzle now unless I have enough filled in to not be bothered by redoing the fill ins.
