Tournament Tennis is a single-player and multiplayer sports and arcade game in which players compete in tennis matches, with core mechanics involving serving, volleying, and strategic positioning to outplay opponents. In this game, players progress through tournament stages such as quarter-finals, semi-finals, and finals, with matches played over 3 or 5 sets, requiring a two-game lead to win each set, and featuring tie-breaks at 6-6 in all but the final set. It stands out with its pioneering approach to tennis simulation, establishing conventions like tournament progression and set rules that influenced future sports games, and it offers a variety of platforms including Atari ST, Commodore 64, DOS, and Sinclair ZX Spectrum, among others.
