Discs of Tron is the second arcade game based on 1982 Disney film Tron.

While the first Tron arcade game had several mini-games (Gridbugs, Light Cycles, entering the MCP cone and Digital tanks), Discs of Tron is inspired by the Jai alai sequence in the original 1982 film in which Kevin Flynn is forced to play against Crom, leading to Crom being “derezzed” by Sark. Tron is also introduced later, as Flynn witnesses him competing against (and defeating) four of the MCP’s “warrior elite”.

In the movie, Flynn and Crom stand on top of a platform made of five concentric circles that disappear if an energy pellet, thrown from an arm extension, touches a target between both platforms. Discs of Tron uses several platforms, and the player must beat Sark by throwing discs at him (a maximum of three at a time, which would return to the player) and eventually derezz him or push him outside the platforms. While the player, along with the discs, can use a deflector, Sark has two more weapons: a chaser and a super chaser, that can only be destroyed with the discs.

As the game progresses, the player is given different configurations of platform rings to jump and stand on. The video game also uses a spinning knob that is used to move a mouse-like cursor around the playing field so you can judge where the discs will deflect off the walls and on later levels the knob can be pulled up or pushed down depending on the height of the platforms.

This game was released just before the video game crash of 1983.
