Image Number 5 for United States Patent #7955171.
An electronic gaming device, such as a slot machine, is provided which initiates a game without input from a player. After initiating the game, the device may present one or more active game elements, such as rotating slot reels, to the player. The device determines an outcome of the game corresponding to a final position of the active game elements. The device further provides an interval to the player to make payment before the final outcome of the game is displayed. Payouts to the player are based on the final outcome and whether the player has made payment. Payouts may be increased based on a measurement of the player's participation rate in a series of games and the frequency of the games played, as measured by the device.
