Tron is a 1982 action video game developed and published by Bally Midway for arcades, based on the Disney film of the same name. The lead programmer was Bill Adams with Earl Vickers programming the music.

The game was a major success, with approximately 10,000 arcade cabinets sold, and was awarded "Coin-Operated Game of the Year" by Electronic Games. A number of other licensed Tron games were released for home systems, but were based directly on elements of the film and not the arcade game. In 1983, Tron was followed by Discs of Tron, an arcade sequel which was not as successful.

Tron consists of four sub-games based on events and characters in the movie. In general, the player controls Tron, either in human form or piloting a vehicle, using an eight-way joystick for movement, a trigger button on the stick to fire (or slow down the player's light cycle), and a rotary dial for aiming. The goal of the game is to score points and advance through the game's twelve levels by completing each of the sub-games. Most of the 12 levels are named after programming languages: RPG, COBOL, BASIC, FORTRAN, SNOBOL, PL1, PASCAL, ALGOL, ASSEMBLY, OS, JCL, and USER. The game supports two players alternating.

At the start of each level, the player is taken to a "Game Grid" selection screen divided into four quadrants. The player must choose a quadrant, each of which corresponds to a different sub-game. The sub-game in each quadrant is not known to the player until it is selected. If the player fails the game and loses a life, they are taken back to this selection screen and an icon representing that game is now visible. Failure to choose a quadrant before an on-screen timer runs out results in a sub-game being chosen at random. Once the player completes a particular sub-game, it is taken out of play until the start of the next level.

The sub-games are as follows:

The player must guide Tron to the flashing circle of an Input/Output Tower within a set time limit while avoiding or destroying Grid Bugs. This game is based on the I/O Tower scene in the film, while adding the Grid Bugs as enemies (which were only briefly mentioned in the film). A bit occasionally appears on the screen and can be picked up for bonus points.

The player must break through a rotating shield wall protecting the MCP cone and enter the cone without touching any of the shield blocks. This game is based on Tron's final battle with the MCP in the film, but changes the nature of the MCP's shield. Bonus points are awarded for destroying every block in the shield.

In a player-vs-AI variant of the Snake game concept, the player guides Tron's blue Light Cycle in an arena against one or more yellow opponents. The objective is to force the enemy cycles to crash into walls, jet trails, or each other, while simultaneously avoiding them. When an enemy cycle crashes, both it and its trail disappear. This game is based on the Light Cycle Arena sequence in the film, though the colors of the friendly and enemy characters are reversed. This is the only sub-game in Tron to not use the rotary dial.
