Abstract

Trajectory-based games of chance are described that may be implemented on a video gaming machine. In a trajectory-based game of chance, a trajectory of a game object may be generated in a 3-D gaming environment. A wager may be made on an aspect of the game object'"'"'s trajectory in the gaming environment such as a termination location for the trajectory of the game object. The aspect of the game object'"'"'s trajectory may occur according to a known probability. Hence, an award for the trajectory-based game of chance may be proportional to the probability of the aspect of the game object'"'"'s trajectory occurring.
