Rock · Paper · Scissors
Play against the computer with your real hand. Show ✊ rock, ✋ paper or ✌️ scissors to the camera when the countdown ends.
Everything runs on your device. Your camera image never leaves your phone or computer.
Start the camera to play
Hold your hand up in front of the camera, about half a metre away.
How it works
Reading your hand
A gesture model finds 21 points on your hand and recognises a closed fist, an open palm and a victory sign — rock, paper and scissors.
Fair play
The computer picks its move at random only after your move is read, from what the camera saw in the half-second after “Shoot!”.
Private
Everything happens on your device. No video is recorded or sent anywhere.
