IDEAL's treatment of tic-tac-toe enclosed in a large 18" square box.
The large plastic gameboard consists of four gently sloping ramps which extend upward from each side of a tic-tac-toe grid. There is a circular hole in the center of each grid segment to accept players' discs.
Each player is given eight plastic discs of their chosen color and a device to release the discs (basically a circular piece of plastic with a raised slit) down their particular ramp. A turn consists of aiming a disc and releasing it down the ramp. Discs that fail to come to rest completely within a hole are removed from the board and used later if required. Only the top disc showing in any given hole counts in gameplay.
The first player to land three of their discs in holes so that they form a straight row in any direction is the winner.
