Tridball is a Game Boy Color game created by Aaron St.John written in assembly language.

This game puts a 3D spin on the game of Pong. Because the GameBoy's processor does not have support for floating point numbers, division, or multiplication, it uses compressed look-up tables to run the needed calculations to show 3D graphics while staying under the contest's 32KB limit.

It was developed for the GBdev 2000 Competition and won second place.
