This transformational geometry game develops spatial visualization as well as both deductive and inductive reasoning. Each player uses 5 pentominoes (chosen from a set of 12 pieces) and two blocking chips on a 13-by-9 grid to entrap all 5 of the opponent’s pentominoes. In the placement phase, players must strategically select and place five pentomino pieces onto the gameboard. In the movement phase players attempt to entrap the opposing player’s five pentominoes by rotating, flipping, or sliding their own pieces.
