Full size roulette and blackjack tables, proper croupiers in black tie, and fun money that people take alarmingly seriously by about the third hand.
It’s the entertainment that solves the awkward middle of the evening. The guests who won’t dance now have somewhere to be, tables of strangers end up cheering the same number, and the quiet colleague from accounts turns out to be terrifyingly good at blackjack. Croupiers teach as they go, so nobody needs to know the rules to join in.
Runs for a couple of hours alongside everything else, with a prize for whoever finishes with the biggest pile of chips. Weddings, corporate nights and birthdays where you want the room mixing rather than sitting.
