Behind each numbered square is an object. Each player takes a turn by choosing two matrix squares (on a 16 or 30 square board). When a player chooses a square, an object is revealed. If the two squares' objects are identical, the player scores one point. You also receive another turn. When you select two squares that are not identical, in two player games, the other player makes a selection. In one player games, the computer scores one point and you select another two squares.
