How does the sleeve decide who wins if both players tap at the same time?

Pad 1 (Player A) and Pad 5 (Player B) each use their own touch channel, so both taps register independently and a genuine tie replays the round instead of guessing.

Can I change the throws or add a fourth option like lizard and Spock?

Yes. Open the Sleeve Studio app, edit the throw list in plain English, and send it over Bluetooth in under 10 seconds.

What happens if a drink spills on the sleeve mid-bet?

Unsnap and slide the sealed 8×32 LED and BLE module out of the inner pocket in five seconds, rinse the matte-black compression sleeve in cold water, and hang it to dry.

Rock-Paper-Scissors Bar-Bet Judge on a Wearable 8×32 LED & Touch Sleeve

Tap Pad 1 at your elbow to cycle Player A's hidden throw, tap Pad 5 at your wrist to lock Player B's throw, and the 8×32 RGB LED matrix splits into two 16×8 icon panels that reveal both hands and flash a pixel winner banner on your washable $199 sleeve.

Fair reveal, 1 sleeve: Pad 1 and Pad 5 cycle each player’s hidden throw behind a scrambled icon, then the matrix flips both hands face-up and crowns the winner.
Built for a 95 dB bar: Settle the bet on sewn fabric pads that shrug off spilled drinks — no trusting a stranger’s screen or arguing over a shaky camera.
Pre-loaded & customizable: Ships as one of 50 built-in modes; add a fourth throw or custom stakes in the Sleeve Studio app.

Why Shouting Rock-Paper-Scissors Over a 95 dB Bar Fails Without a Referee

An impartial referee: Both players watch the same pixel reveal at the same instant, so a loud room can’t argue over who threw what.
Gesture-safe on wet hands: 5 sewn copper-nickel pads keep working after a spilled round — no glass screen to risk across the table.
Peer-reviewed textile roots, shipping hardware: The Oct 2026 NUS Nature paper coined “garment GUI” with a lab-only woven pixel fibre (not for sale); our shipping $199 sleeve uses 5 sewn conductive-fabric pads and a removable 8×32 LED pod.
