Bitcycles

A modern Web tribute to the legendary Commodore 64 party game Ultimate Tron II (Oliver Stiller / Masters' Design Group, 1989).

The Nostalgia: 6 Players on 1 Keyboard

Back in the C64 era, up to 6 players crowded shoulder-to-shoulder around a single breadbin keyboard, frantically tapping keys as lightcycles turned with pixel precision.

Bitcycles brings back that raw couch-multiplayer energy! Play locally on one keyboard or join friends over the internet across laptops, desktops, and mobile phones.

Controls & Gameplay

  • Keyboard: Select your turn keys (Q/W, Y/X, B/N, K/L, <Down>/<Right>, <Numpad 2>/<3>).
  • Mobile / Touch: On-screen left/right directional buttons for high-speed thumb reflexes.
  • Objective: Trap opponents with your neon light trail, survive simultaneous crashes, and outsmart rivals to claim the score lead.

Pure Web Tech Stack

Built with zero heavy frameworks: pure ES Modules, deterministic 40 FPS target-timestamp physics loop, binary WebSocket protocol, and an optimized HTML5 canvas delta renderer.
