Equipment consists of a 7x7 board and watermelon shaped pieces in Green and Red. There are 24 pieces of each color. The board starts off empty. Green goes first. For his first move, Green is not allowed to place any piece in the center space. Players take turns placing a piece on any empty space. They are attempting to form squares using their tokens to mark the 4 corners of the square. Squares can be any size and any orientation. Which sometimes makes them difficult to perceive. It is possible for a single piece to complete the corners of several different squares. After a player sets a piece, they check to see if any new squares were formed. They make note of how many and keep a running total. A player is given a reasonable time to count up all the new squares, and then the next player may take his turn. If a player spots any new squares after the other players sets a piece, that player loses those points. After the last piece is set, the scores are tallied. High score wins. -description from designer
