The game board consists of a square grid with 400 spaces, and each player has a set of 21 uniquely-shaped pieces, each with a different combination of squares. The pieces come in four different colors: blue, yellow, green, and red. The objective of the game is to place as many of your pieces on the board as possible while blocking your opponents from doing the same.

To start the game, each player chooses a color and takes all of the corresponding pieces. The first player places a piece of their choice in one of the four corners of the board. The next player must place their first piece so that it touches the corner of their color on the board, but does not touch any other pieces of their color. Players take turns placing pieces until no more pieces can be placed on the board.

The game ends when all players are unable to place any more pieces on the board. Players then count up the total number of squares on the pieces they have left and subtract that number from their total number of squares placed on the board. The player with the highest score wins the game.
