This is a simple game like you used to play. The board has 21 different cards with duplicates for a total of 42. Turn them over one at a time to match pairs. If the two cards don't match they are flipped over. You need to try and remember where they are on the board. 

Continue matching pairs until the board is cleared. Try to clear the board in the least amount of tries as possible.  Matched pairs are saved.

Lowest tries is saved in iCloud
