Dazzle Dart © 1976 Abelson & Goodman & DiSessa.
A fictional sport in which two teams of two players compete and try to fire a beam of light into the opposing team's goal. Players can move forward and backward and rotate around their axis. Each player carries a giant mirror that deflects the beam of light. To score the beam of light must be deflected by at least one other player and hit the goal. Aside from shot the beam can also be passed to to the team mate, which is instant and cannot be blocked.
