GAME EQUIPMENT AND METHOD HAVING SIMULTANEOUSLY PLAYED, BALANCED, MULTIPLE GAME THEORIES Patent number: 4136881 Issue date: Jan 30, 1979

In the area of parlor games and particularly business related parlor games, many attempts have been made to simulate actual business conditions and practices.

This approach has limited the ability to simulate actual business conditions since in real life the “players” operate under differing rules of conduct.
