This cartridge plays the most advanced PONG variant released for the Video 2000. As a matter of fact, it provides on-screen scoring using two rows of squares (one per player). One square is added each time a point is marked. The game is somewhat hard to play because there is no manual serve, hence a continuous game. The ball speed increments as far as the players catch the ball, and the system produces a beep when the ball is lost.

Because the game is quite advanced, it required more complex circuits. Although a simple PONG game could be designed with a few chips, the on-screen scoring feature required much more components. For this reason, this cartridge used two circuit boards: the Tennis (#4) board with the main connector, over which an additional board holding 17 chips has been added to add on-screen scoring. Over 22 CMOS chips are used by both circuits, which is about twice the amount the system contains (Philips Tele-Spiel ES-2201 contains only seven chips and Videomaster Rally contains only five or six chips; obviously, the games are not of the same quality...)
