Addiciting Fun... Fun... Fun
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.
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.
Very challenging to a guy who thought this would be just a time waster. Very addictive if you hate to be beat!
It works but sometimes gets stuck. Good level of challenge in the puzzles.
It Works Extreme is a bit wobbly, not always offering solvable puzzles
