Hand cricket on your camera

No sign-up. vs Computer: your video stays on your device. Friend game: your video, and your voice if you turn it on, go to your friend, directly or via an encrypted relay that only passes them on.

Throw 0–6 with your hand. The camera umpires.

A sample match: you and the computer shake your fists, one, two, three, and throw a number from 0 to 6. Different numbers: the batter scores theirs. The same number: OUT.
