How to play

Click start and allow camera access. The game calls rock… paper… scissors… SHOOT! — throw your gesture at the camera on the shout. Recognition uses MediaPipe's hand landmarker (21 tracked points) and a simple finger-extension classifier:

rock — closed fist, all fingers folded
paper — open palm, all fingers extended
scissors — index + middle finger extended, rest folded

The AI picks uniformly at random — no peeking at your hand before the reveal. First to 5 wins takes the match; draws replay the round without scoring.

Privacy

The camera turns on only after you click start, and the light goes off the moment you hit stop camera or leave the page. Frames are processed by a WASM model served from this site — nothing is uploaded, no account, no tracking of any kind on your input. Verify it yourself: open DevTools → Network while playing and watch nothing leave.

Requirements

A webcam and a reasonably recent browser (Chrome, Edge, Firefox, Safari 16+). The tracker prefers your GPU and falls back to CPU. First load fetches ~18 MB of model + WASM once, then it's cached.
