Blokus

Blokus is a fast-paced 2-4 player strategy board game where players compete to place all 21 of their colored, Tetris-shaped pieces on a 400-square board. The sole rule is that each new piece must touch at least one other piece of the same color, but only at the corners. The game ends when no more pieces can be placed, and the player with the lowest score (fewest squares remaining) wins.
