Zozzle

Zozzle challenges players to complete a nine-piece puzzle before any opponent, but players will need a good memory to put all the pieces in the right place.

To start the game, the 45 tiles – five tiles each of nine different images, with the nine images combining to form a 3x3 square – are placed face down and shuffled. On a turn, a player turns over two tiles. If the images match and that player doesn't already have that image in her puzzle, she claims one of the tiles, turns the other face down, and takes another turn. If the images don't match or the player has previously claimed that tile, she turns the two tiles face down and ends her turn. Finish your image before anyone else, and you win.
