About The Game

Discs of Tron is an arcade video game based on the 1982 film Tron.


The environmental version of this game is huge, weighing in at over 700 pounds (317kg). The game was often sawed in two to make it easier to move. The cabinet, though it looks like it should come apart, does not (the roof and floor boards span both halves of the cabinet). The environmental is called such because it attempts to replicate the environment that your character on the screen is experiencing. The player stands inside the cabinet on a disc, and lights around the disc flash when your character dies (just like on screen). The surround sound replicates the sounds of discs that whiz by your character. The two player upright looses a lot of the bells and whistles of the environmental, including speech (see 'Updates' section for more information).

Discs of Tron was originally designed to be a part of the original "Tron" coin-op, but was cut out at the end and set aside for refinement and release as a stand-alone coin-op in its own right.

Discs of Tron is inspired by the short sequence in the film where the character Flynn beats another trapped program (and has to watch helpless as Sark 'de-rezzes' him), and when Tron is introduced, beating four 'computer players' very early in the movie.

David Bagenski holds the official record for this game with 418, 200 points on June 28, 1986.

A Discs of Tron 'prototype' machine was shown at the 2003 classic arcade games show 'California Extreme' in San Jose, California.
