This game is basically a race between two players navigating the same maze.
Two large plastic reversible gameboards are used. The boards have a linear maze molded on one side and a circular maze on the other. The boards have "finish" holes at the top that each contain a metal contact. A wire leads from the board to a column that has lights in each players colour.
When the steel marbles used to navigate the maze all come into contact with their respective finish holes the column lights up in that players colour, indicating victory.
