A prompt goes up: name a pizza topping, a reason to be late for work, something you would find in a hotel room. Everyone types one answer in secret on their own phone. The trick is that you are not answering for yourself, you are answering for the room. The question is never what you like, it is what everyone else is about to write.
Once the answers are in they land on the shared screen together, grouped by whoever wrote the same thing, with the matching ones growing bigger. Nobody has scored yet, so the room gets to read them cold and work out for itself where it converged. Then you score the round and the biggest group lights up.
The round is worth 1000 points and everyone in that group takes it, while everyone else takes nothing. If two answers tie for biggest, the 1000 is split between them, 500 each, so reading the room outright beats landing in one of two halves it split into. And if every single answer is different, no crowd formed and nobody scores at all, which is its own kind of result for a room that thinks it knows each other.
