Tron-style neon light bike duel. Carve a glowing trail and force the AI to crash. First to 3 round wins takes the match. Free, browser arcade.
Arrow keys or WASD to turn (90° only — no reverse). On mobile use the on-screen direction pad below the arena, or swipe across the arena. First to crash into a wall or any trail loses the round.
Light Cycle is a head-to-head trail game inspired by the iconic light cycles from Disney's 1982 film Tron. Two bikes streak across a closed grid leaving a permanent neon wall behind them; the first to crash — into the arena edge, into their own trail, or into the opponent's — loses the round.
Despite its arcade simplicity the game is a genuine spatial puzzle. With every move both bikes shrink the open space, and the late-round corridors require you to think two or three steps ahead. The trick is to leave yourself an exit while denying the AI one — a discipline competitive players call "area control".
Our AI plays with a two-step look-ahead and a bounded flood-fill so it picks the direction that keeps the most open space available. It also nudges toward you in roughly half its tie-breaks, which makes the late game an aggressive cat-and-mouse on the diagonal. Best of five — first to three round wins takes the match.
No. 180° turns are disallowed — you can only turn 90° left or right relative to your current direction.
Driving off the grid, into your own trail, or into the AI's trail. If both bikes try to enter the same square on the same tick, it counts as a mutual crash and neither side scores.
Every tick it scores each legal direction by checking the next cell is safe, the cell two steps ahead, and a bounded flood-fill of nearby open space. Ties bias toward your position, which keeps it aggressive.
Each tick shaves a fraction of a millisecond off the next one. Rounds that started smooth get genuinely twitchy after thirty seconds — that's by design.
It's inspired by Tron's light-cycle sequence, but rendered as a top-down grid game in your browser. The core mechanic — trail-against-trail — predates Tron in arcade history under the name Surround (1978).
