Nice app. A great way to wait. Helps keep your mind sharp when you have time to kill. When hilited number can't be seen, rotate the screen.
Love it! Great way to waste time.
Good one! You can disable the timer and everything! However, when I hit undo, pencil marks that had been eliminated by the entry I just undid need to be restored.
Sudoku A good little app

Great One of the best sudoku apps I've ever played :)
