This magnetic mind game is suitable for 2 or 4 players – with 3 brains each. It’s not an ordinary Tic-Tac-Toe, because the Xs and Os in this game float. The 13 Magnetic Rings are divided among the players. The first player lays a piece with a red circle up on any of the 9 pegs, except the center. The second player then places a piece on any peg. If a piece is placed on top of another piece, red-circle sides must always face red-circle sides and blank sides must always face blank sides. This ensures that the pieces levitate. The first player to get three in a row, wins.
