Phraffle!

How to run a giveaway

1. Get the whole room to stand up.
2. The reels show the last four digits of a phone number. Everyone stays standing only while the digits match their own.
3. Tap the right-hand reel to stop it — about 90% of the room should sit down.
4. Tap the next reel to its left. If nobody's left standing, spin it again and retry.
5. Last person standing wins.

In a room of 100, it usually takes 2–4 taps to land on one winner.

Crowds over 10,000 need an enterprise license: $20k, Venmo accepted 😉
