Tennis (cassette 4) plays the basic version of Super Tennis
without on-screen scoring. The game is somewhat hard to play due to the automatic serve
and the increasing ball speed (a beep is produced on ball loss).
One might wonder why this cassette contains seven more chips than
Badminton. As a matter of fact, the differences
with Badminton are the player motions (vertical only in Badminton,
bi-directional in Tennis), the condition the system uses to produce a
beep (when the ball is caught in Badminton, or lost in Tennis), and
finally the central line (net) which is indeed thiner than the wall in
Sparring. The answer is simple: by design, the system can only produdce
two players (of variable size) and a ball, hence the need of additional
chips to draw the central line in Tennis. Sparring does not require those
chips because the second player has an infinite height to form a wall.
Tennis game. No on-screen scoring.
