Big groups need games that keep everyone busy at the same time. Games where people wait ten minutes for their turn lose half the room. On Snazzlebop, eight players play at once on their phones and up to 30 more join as the audience, with their own things to do.
For bigger crowds, switch on Teams: two sides, several people per phone if needed, and combined scores.
Four or five players: Alibi and Imposter shine, because every clue and every accusation matters. Six to eight: Mafia Night and Codewords, where the arguing is half the fun and teams can plot together.
Mixed crowds who don't all know each other do best with games that need no private jokes: Mystery Box Auction, Hot Potato Bomb and team trivia.
The audience isn't just watching: they react live, predict winners, trade in the Friend Stock Exchange during a show and vote for the night's MVP.
Rotate players between games: the people in the audience for one game can take a seat in the next.
Put the show on the biggest screen in the room with TV mode, so the people watching can follow along.
Eight players per room, plus up to 30 in the audience. Two people sharing a phone count as one seat.
