Use the arrow keys to control the blue light cycle. Don't hit the blue or yellow line. A score of 10 wins Based on the original Tron game, with music from the new Tron movie by Daft Punk. (If music doesn't start, hit the green flag again.) Single player light cycle game. Enjoy! Version 2.0 changed how the yellow light cycle moves and improved control of the blue cycle, plus some other subtle tweaks. Version 2.1 made more improvements to the yellow car's movement, and added the difficulty that Blue Cycle cannot cross its own line. Comments welcome.
