Blokus game

BLOKUS
Play Blokus with the whole family! Learning the rules takes less than a minute, and the fun of strategizing never ends! Players receive sets of 21 pieces in red, blue, green, or yellow, which they place on the board in turn.
One rule applies: each piece must touch another piece of the same color, but only at the corners! The goal is to place as many pieces on the board as possible.
The game ends when no more pieces can be placed, and the winner is the player with the fewest remaining pieces.
