Played in 2 teams. Clue giver for team one places a disc in the gizmo, reads the one or two word answer, gives a one word clue, and starts the timer by pushing a mouse ear on the gizmo. Team two has until the lights go out on the timer to yell answers. If they don't get it, the gizmo is passed to the other team, whose clue giver may give one new word as a clue. Gizmo goes back and forth until someone gets it.
