Welcome to Genius Square, where there are tens of thousands of possible challenges and always at least one solution. Roll the dice to place your blockers, then be the first to fill in your square with the remaining pieces. A fast-paced and spatial reasoning brain-stumper, this game allows for solo or head to head challenges. Playing with more than two people? Buy a second set for twice the fun! Fans of Blokus and Tetris will enjoy. For 1-2 players.
