Table Tennis requires Odyssey's game card #1, and is an early father of Pong.
Each player controls one "paddle" on opposite sides of the screen. The objective is to hit the moving ball past your opponent's side, winning a point, while preventing your opponent from doing the same to you. At all times, the players must avoid the top or bottom of the screen (otherwise, it's called "ball off the table").
There's no score keeping on screen, so the players must keep score by themselves. The first player to get 21 points wins the match if he has at least a 2 point margin. Otherwise, play is continued until that margin is attained by one of the players.
