Tennis for the Atari 2600 is a vintage sports video game belonging to the simulation genre. Released in the early 1980s, it presents a simplistic representation of tennis, befitting the era's graphical and technical limitations. Players control pixelated figures that volley a square ball back and forth across a rudimentary tennis court. The game can be played solo against an AI opponent or in a two-player mode. Its straightforward mechanics involve serving, hitting, and strategically positioning to outplay the opponent, capturing the essence of tennis with minimalistic controls and visuals.
