What happens if someone taps their pad before the matrix flashes DRAW?

A false start is flagged instantly on that side of the grid (FOUL · P1 EARLY), and the point goes to the patient player.

How responsive is the reaction readout?

Pads 1–5 read fast enough for snappy, low-latency play; precise timing accuracy is still being validated.

Can I customize the loser penalty message in Sleeve Studio?

Yes—use the Sleeve Studio app to scroll any custom dare, drink round, or social handle after a 2-0 victory.

Western Quick-Draw Reflex Reaction Duel on a Forearm LED Sleeve

Turn your forearm into a two-player reflex reaction timer: the 8×32 RGB LED matrix counts down 3-2-1, holds a randomized dark blackout pause, flashes DRAW!, and displays the winner's reaction time (e.g., 184 MS) across Pad 1 and Pad 5 ($199 preorder).

2 players, 1 sleeve: Duelists tap Pad 1 (elbow) and Pad 5 (wrist) after a 3-2-1 countdown and a random blackout pause — first slap after DRAW! wins the point.
Built for a rowdy bar table: 5 sewn copper-nickel fabric ribs absorb fast slaps that would crack a phone screen; keep your phone dry and cold-wash the sleeve.
Pre-loaded & customizable: Ships as Mode #03 of 50 built-in modes; rewrite the loser penalty or speed in the Sleeve Studio app.

Watch the 8×32 RGB LED matrix and 5 conductive-fabric touch pads running social and 2-player game modes on the forearm sleeve. Concept render · simulated 8×32 display · first production run of 500 units.

Why Phone Touchscreen Reflex Apps Lose to Physical Fabric Pads

Instant, fair results: A 256-pixel countdown and a white DRAW! flash settle who slapped first, so nobody argues over a laggy phone touchscreen.
Zero phone risk: Never hand a $1,200 glass screen across a wet bar table — 5 sewn fabric pads take the hits instead.
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.
