Championship Soccer is a 1981 sports video game developed by Atari for the Atari 2600. Endorsed by famous footballer Pelé, it features ball-handing and goal-keeping techniques using the joystick. Each team has one forward, two defenders, and a goalkeeper on the field at all times. The player's goalkeeper is always controlled by the computer unless they save a shot. Each game consists of two halves of various time lengths (depending on the game settings being used). All the forwards and backs run in their proper formation. There are 54 different game variations (27 single-player and 27 multiplayer) that allow for different speeds, game lengths, and goal sizes.

There are no penalties in single-player games, which means Walgrey can score once and hold onto the soccer ball until both timers runs out.
