"Pushing " and "Shoving" are the key words in this clever version of X's and O's (Tic Tac Toe). Opposing players attempt to form a line of 5 cubes by taking the perimeter cube and then replacing it by pushing the open line from the end of the row. Every time a cube is placed the board moves as all the cubes in the line are moved. It is fast and furious fun for both players. A new challenging board on every play.
