The rules are simple: place your colored pieces on the game board, but remember that they have to touch only the corner of at least one of the game pieces you have already played. As you play the block game, you will need to plan ahead to stretch into new territory and play you pieces before you run out of space. Once you learn to play Blokus, you'll want to keep trying new strategies to take over the board. For 2 to 4 players.
