A 2 player game. Players take turns placing tiles into the grid trying to form squares. Completed squares are marked, and the player gets another turn. When the board is filled, the person with the most squares wins. This game is the same as the paper and pencil game "Dots and Boxes" played on a 7x7 box grid. The title of the German edition is just "Square". The German word for the traditional paper and pencil game is "Käsekästchen".
