25 cubes are placed in the center of the board. At the beginning of the game, the cubes all have a blank top face. The two players or teams choose who plays with crosses, who plays with circles, and who is to start.
The Object of the Game:
Make a horizontal, vertical, or diagonal line from 5 cubes bearing your symbol.
On his turn, the active player takes a cube that is blank or bearing his symbol from the outer ring of the grid. He rotates it to show his symbol (if needed), then adds it back to the grid by pushing it into one of the ends of the row. Thus, a few pieces of the grid change places each turn, and the cubes slowly go from blank to crosses and circles. Play continues until someone forms a line of five cubes bearing his symbol, winning the game.
