A night game, also called a nighter, is a sporting event that takes place, completely or partially, after the local sunset. Depending on the sport, this can be done either with floodlights or with the usual low-light conditions. The term "night game" is typically used only in reference to sports traditionally held outdoors. Although indoor sporting events often take place after local sunset, these events are artificially lighted regardless of the time of day they take place.
