pretty....but

this is very pretty, but this doesnt work easily. I tried the undo button to clear a square, when I accidently hit a square I did not mean, and it did not work on the cell I wanted it to, but took everything else off. I tried doing the instructions again to undo, didn't work. I want to be able to click on a number, then go click all the squares I want for that number, not go back and forth each time. This did not have that option, unless it is hidden.

So simple and calming!

I wanted to play a sudoku game with no flashing ads or unnecessary parts, and this game is perfect. The background images are very relaxing and the game is so simple. Really recommend this!

Decent app

But I would like to be able to turn off the color change when I correct numbers are placed on the board.
