This game is all about matching the colors. A "quartet" is a block with 4 colors on each side. The goal is to place matching-color sides of the quartets next to each other as much as possible. The larger the matching-color regions, the higher the score! If there's no matching-color side for the incoming quartet, that's an illegal move and you lose the point for that quartet. You'll be scored based on the percentage of the number of matching-color sides plus the number of completed full rows and columns of quartets to the total number of quartets attempted. Just like the IQ, a percentage score of 100% means you're average, 200+% means you're a genius! You can rotate the colors in the incoming quartet using the buttons at the bottom of the screen.
