A cat in a black mask steals fish and runs across live traffic. Pick a lane, watch the multiplier, cash out before the street takes it back.

CATFISH is a complete, playable game , built from an empty repo with the Gemini 4 Argon.
No engine, no template: Vite + three.js, plain JavaScript, 583 kB bundle / 152 kB gzipped, and it runs in a phone browser.

I don't want to sell you "AI made a game". Here is what you can check:

· The odds aren't vibes. LEFT 0.90 ×1.1056 · STRAIGHT 0.70 ×1.4214 · RIGHT 0.45 ×2.2111, over 8 junctions → 0.995^8 = 96.07% RTP. A unit test samples the payout and fails the build if it drifts more than 2.5 points. It runs in CI on every push.

· The 3D city and the character art came from image models (Nano Banana for the stills); the code was written and refactored with Gemini.

· The paytable, the RTP verification and the bug fixes were mine. Real ones, not cosmetic: a stake clamp that let you bet more than your balance, and a global Enter shortcut that stole the key from focused buttons.

Play money only. No wallet, no server, nothing to lose but a fish stack.
