From the packaging: "The game consists of 36 square tiles with between 1 and 6 dots on each side. The object of the game is to place all of your tiles, ensuring that the numbers on any touching sides are matched, while scoring as many points as possible. Points are scored according to the number of sides matched, with the number of points awarded being the square of the number of sides matched." This game is different from Quad-Ominos which has numbers in the corners instead of dots on the sides of the pieces.
