Press Your Luck

Contestants answer a series of questions and earn money with each correct one. After the question round, contestants then have to gamble those winnings on a light-board that flashes in a seemingly random fashion and hit a button to stop it at a hopefully desirable spot. The results can range from increased winning to hitting the "Whammy" which causes a cartoon character to appear and the player loses all the winnings.
