  • Method of playing a casino game
    Patent number: 6017033
    Abstract: A method of playing a casino game rewards a player for how quickly he can "lose". At the outset, the player is provided with a tote. A timer begins, and the player uses the tote to place wagers in the game. The tote is increased when those wagers win and is decreased when they lose. When the tote is reduced to zero, the timer stops. The time it took the player to reduce the tote to zero is measured against a standard, and the player is rewarded based on that performance. The method is particularly well-suited for use in amusement devices, such as arcade games.
