Abstract: An apparatus for playing a tennis game having a rectangular grid containing axes of abscissas and ordinates. Dice are used to determine if a player may serve into and/or into and through the appropriate advantage or deuce courts. Dice are also used to determine if a player may move to and return the serve. Initial service and defensive positions are chosen by the players prior to the beginning of the service. A process for teaching the game is also disclosed so as to enable the players to learn the game as applied to the axes of abscissas and ordinates.
