Isaac 1.1 - Isaac is the type of game that takes a minute to learn how to play, but can keep you occupied for hours. Just hit the start button and repeat the sequence back to Isaac by tapping each piece as Isaac did. You can choose to work with from 2 to 10 pieces. You can also choose to finish at 8, 20, 30 or more levels (of course if you mess up, the games over!). Fun Newton game.
