ABSTRACT:
A method and system for monitoring court games is described in which a counter is actuated by a card bearing a pre-determined code. Upon being actuated, the counter is pre-set to a pre-determined period of play for a game in a court with which the monitor is associated. The counter then counts the elapsed period of play and displays to other players waiting to use the court the period of play still remaining, confirming to them in a positive fashion the period they must wait to use the court. Upon expiration of the pre-determined period of play, the event monitor signals this condition permitting the other players to actuate the system and commence their use of the court.
