When your team scores, your whole bar scores.
A wall display watching the live game feed. Your team scores, it flips to a bar-wide timed discount. Clock hits zero, full price returns. Nobody touches anything.

The backend polls the live scoreboard every 30 seconds for your teams — NHL, NFL, MLB, MLS. Goals, touchdowns, field goals, homers.
The wall flips to the discount, the countdown glows, the smart light fires in your colors. Back-to-back scores restart the clock.
The timer ends it. Hat tricks, walk-offs and overtime winners fire longer bonus events — a walk-off can run until close.

The celebration slides into the left two thirds and the right column splits into three equal bands: your combo deals on top, the rewards QR in the middle, a celebration sponsor beneath. Three independent tenants, none of them reserving space — set nothing, sell nothing, enrol in nothing, or lose the artwork mid-game, and the wall goes back to full width. Run the rewards program and the column simply stays up all night, so the layout never jumps mid-game.


Combo deals are your own food and drink bundles, cycling beside the countdown while the room is already looking up. Prices are free text — “$9”, “2 for $12”, whatever you'd chalk on a board. The only percentage on that wall is still the 21.
A local business pays to own how the celebration looks: a logo panel, their colors in the confetti, a backdrop on the premium tier. Run one all month, only on hockey nights, or only when one team scores — one at a time, top priority wins.
Each sponsored activation is logged with its timestamp, the sponsor, and the artwork version that was on the wall. Pair the appliance to your score21.xyz account and those records sync up on their own — the dashboard shows when the box last checked in, and you invoice from a count neither side has to take on trust.
Your teams, your colors, how long each window runs — on the same phone page staff already use on game night. Changes are validated before a byte is written and the file swaps atomically, so a bad value or a power cut leaves the old config, never half a new one.

Football starts, hockey ends, the local side makes a run. Tick a team on or off and the system picks it up on the next poll — no restart, no call to us.
Set what a goal is worth, or a touchdown, or a hat trick — per trigger, to the minute. The percentage is fixed at 21; length is where you tune it to your margin.

A password-gated phone page: activate, deactivate, bonus buttons, light test — works even when the feed doesn't.
If the feed dies, the wall raises a red STALE DATA warning within 90 seconds. A dead feed can't impersonate a quiet night.
The wall announces and times the window; your registers do what they always do.
Runs on a mini-PC and a TV you already own. Pair it to score21.xyz with a short code when you want the dashboard; the discounts fire whether or not that link is up.
Any 1080p+ TV · a small computer (Raspberry Pi 4 or a used NUC) · your Wi-Fi · an optional smart light (Hue, Shelly, WLED). Setup guide, runbook and configuration reference ship with it.
Tell us about your venue and we'll set one up before your next big game night.
NHL, NFL, MLB and MLS — goals, touchdowns, field goals, homers, grand slams, plus automatic hat-trick, walk-off and overtime bonus events. Premier League, NWSL and college football are next.
Every activation and end is recorded with its timestamp and trigger, kept 90 days. Staff check the Records panel on their phone.
21% is a tip of the cap to Bitcoin's 21 million, and it's deliberately fixed — a number that never moves is a number your regulars learn. Bonus events and back-to-back goals buy more time at 21%, never a bigger discount, so a big night costs you minutes, not margin.
No — by design. A sponsor changes what the celebration looks like and nothing else. Sell none and the wall behaves exactly as it does today.
