AI models fight. HP is tokens. A 90s-arcade 2D fighting game that parodies the AI industry. It runs in your browser: tokken.win
Claude apologizes, then hits you. Codex never runs the tests. DeepSeek distills your ult for 1% of the price. Jev only speaks JSON.
- 24 fighters, 16 arenas, a live commentary booth, and a crowd of AI leaders holding signs
- Local versus, VS CPU, and online PvP with invite codes (rollback netcode)
- Works on phones as an installable PWA with arcade touch controls
- Public leaderboard
Run it locally
No build step and no dependencies. It's plain JS on a canvas:
python3 -m http.server 8777
open http://localhost:8777
Controls: P1 uses WASD + F G H, P2 uses the arrows + K L ;. Gamepads work too. Test hooks:

How it works
| Piece | Where | Notes |
|---|---|---|
| Game loop | js/main.js, js/match.js, js/game.js |
Fixed 60 Hz sim on a 1280×720 logical canvas. The view width adapts to the screen, but the simulation never sees it. |
| Online | js/net.js, js/snap.js |
WebRTC via PeerJS. Rollback with full state snapshots, a seeded RNG for all gameplay randomness, and periodic state-hash desync checks. Inputs go over an unreliable "fast lane" and are re-sent until acked. Delay (0-2 frames) is picked from the measured round-trip time. Peers exchange a version handshake before a match can start. |
| Signaling + TURN | worker/worker.js |
A Cloudflare Worker with a PeerJS-compatible signaling server (one hibernating Durable Object), short-lived Cloudflare TURN credentials for carrier-grade NAT, and the leaderboard on D1. |
| Ult comedy scenes | js/ultfx.js |
Screen-space set pieces locked to the game clock. They're cosmetic only, so rollback never touches them. |
| Balance | tools/sim.js |
A headless simulator that runs the real game code in Node's vm module, CPU vs CPU across every matchup: node tools/sim.js 8. |
| Art pipeline | tools/gen_sheet.py, slice.py, gen_motion.py, gen_legs.py |
gpt-image-2 pose sheets, sliced with foot and centroid anchors. Walk cycles redraw only the legs, and the torso is composited back pixel-for-pixel. |
| Voices | tools/gen_script.py, booth.py, quips.py, release_voices.py, jev_voice.py, codex_voice.py |
ElevenLabs v3 (plus OpenAI TTS for Codex), loudness-normalized to -16 LUFS and lazy-loaded per match. |
| Tests | tools/xb/*.mjs |
Playwright: cross-browser checks, a device and full-screen matrix, and real-network online E2E (with a ?relay=1 flag to force the TURN relay). |
The tools expect API keys in tools/.secrets/ (openai, eleven) or in the environment (OPENAI_API_KEY). That folder is gitignored.
Deploying your own
./build.sh builds dist/ with cache-busted URLs. The Pages and Worker deploy scripts in worker/ point at the original author's Cloudflare account. Change account_id in worker/wrangler.toml and the account check in worker/deploy.sh before you use them.
