The Tron light cycle game, 1v1, in your browser

Everyone who saw Tron remembers the light cycle scene: two riders on a grid, each one leaving a wall of light behind them, each trying to make the other crash into it. CUTOFF is that duel as a real game. One arena, two riders, and every wall of light is a wall — yours, your rival's, and the arena's edge.

How it works

• 1v1, real time. You against one other rider. The first to win two rounds takes the match.
• Box them in before they box you. Your trail is permanent. Use it to cut off their space; the rider who runs out of room first crashes.
• Three boosts per round. A burst of speed to cut across your rival's path — or to escape a trap. Spend them early and you have nothing left for the end.
• The arena closes in. If a round drags on, the walls start to shrink, so nobody can stall forever.
• No luck. Both riders get the same arena and move at the same time. The better rider wins.

Controls

PC: arrow keys or WASD to turn, space to boost. Phone: swipe to turn, tap the boost button. It runs in any modern browser — Chrome, Safari, Firefox, Edge — with nothing to install.
