Abstract: A computer game of chance is described. A system displays, via a user interface, at least a part of a field of play associated with a game of chance. The system receives, via the user interface, a user selection of a region within the field of play. The system evaluates a probability that an object will traverse the user-selected region during any of the random movements by the object from a beginning area to an ending area during a round of play. The system displays, via the user interface, the object moving in the field of play during at least some of the random movements. The system credits a success value, based on the probability, to a player of the game of chance if the object traversed the user-selected region during any of the random movements during the round of play.
