This Mensa award winner develops logic and spatial perception while kids learn to be tactical. Players take turns placing pieces on their board, each starting from their corner. Each new piece must touch at least one other piece of the same color, but only at the corners! The goal is to get rid of all your pieces. Includes one gameboard with 400 squares, 84 game pieces in four bright translucent colors, and an instruction guide. 2-4 players.
