Methods and systems for determining a bonus bowling score may include determining a speed with which bowling pins are knocked down by a player. The speed may correspond to a bonus score that may be used, in some configurations, to break ties. In one arrangement, a bowling game may determine a reference time at which a bowling ball crosses a predefined location in a bowling lane. A speed time may be determined based on when a last of the pins that have been knocked down has fallen. A bonus score may then be determined based on the difference between the speed time and the reference time. In one example, the smaller the difference (i.e., faster speeds), the higher the bonus score. Bonus scores might only be used in tie breaking situations. Alternatively, bonus scores may be used in regular scoring.
