How to play

Allow camera access, then pick a mode. Hand tracking runs at your screen's refresh rate using MediaPipe's hand landmarker — 21 tracked points per hand, up to two hands.

6·7 beat — the screen calls a side: 6 means raise your left hand higher than your right, 7 the opposite. Lock the pose before the timer bar at the top runs out. Every hit grows your combo and shortens the next beat, down to 600 ms. Five missed beats end the run.
target smash — 6s and 7s drop from the top of the frame. Touch them with any fingertip to pop them. Targets spawn faster and fall quicker the longer you survive; five escapes end the run.

Privacy

The camera turns on only after you click a mode, 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; a mid-range phone manages ~20–30 fps, desktops run at full refresh rate. First load fetches ~18 MB of model + WASM once, then it's cached.
