Patent attributes
Multi-player games in which players cooperate and/or compete with one another over the course of several rounds of the game are disclosed. A controller may synchronize gaming devices used by the players during the multi-player games. The controller may send sync commands to the gaming devices. In response to the sync commands, the gaming devices may start a sync timer which defines a window in which certain guarded operations may be accepted by the gaming devices. The controller may send periodic sync update commands to the gaming devices which cause the gaming devices to update their respect sync timers to a time remaining of a master sync timer or window maintained by the controller. The controller may ensure that play of the multi-player game proceeds in a relatively lock-step manner across the gaming devices.
