There's a plethora of sudoku games out there for Mac, most of them more or less the same. zonSudoku makes no exception.
The game will offer you the expected 4x4, 9x9 and 16x16 grids, all three of varying difficulty obviously.
You can also set the difficulty via the slider, which does feel a little imprecise yet clearly offers a difference in difficulty, based on where you set it.
For those of you that aren't so much experienced sudoku players, zonSudoku can display hints and show your errors, so you learn as you play.
We recommend using these at the beginning, however the game will be much funner once you can solve sudokus on your own.
zonSudoku takes up very little place and you can leave it open anytime without worrying about it slowing down your Mac.
It can be good to have on your computer if you're looking for a simple timewaster for taking a break every now and then.
Nothing too surprising in zonSudoku.
