Tennis is a video game released for the Nintendo Entertainment System in 1984. The concept of the game is very basic in that the player controls one person faced against an opponent CPU player. This game uses the same scoring system as "real-life" tennis. The game also features a doubles (2-player) option. The opponent CPU player can be set at 5 difficulties.

The player has only two choices on how to hit the ball: a normal stroke (button A), or a lob (button B). The direction of the ball depends on the timing of the stroke, e.g. if the (right-handed) player hits a forehand early, the ball goes wide to the right, and if he hits it late, then the ball hooks to the left. If the player can reach a lob from the opponent, he can smash it. At higher difficulties, it is almost impossible to win the point except with a smash.
