Ways to play

Same rules, very different game depending on who's in the room. Here are setups that work well.

Game night, dinner, drinks (3–8 people)

Put the host's phone in the middle of the table, have everyone scan the QR code, and you're playing in under 30 seconds.

Create the room with Quick start: five questions, short timers and a practice round are set up for you.
Turn on Sound effects on this phone in the lobby. Only the host's phone plays the start, reveal and final fanfare — not five phones at once.
For the second game, try Spotlight. One "cats or dogs?" tells you how well you really know each other.
With a small group, points depend on how close you were rather than your rank, so a one-off miss doesn't knock you out and games stay close to the end.

Set the host to Host only and put the big screen on the meeting room TV or projector. It shows the question, the timer, how many have answered, and the results in big type.
Turn off Show who got it right so nobody feels put on the spot.
Write questions about your team ahead of time and save them as a question set. Questions only some people know — "What's our newest teammate's hometown?" — make the guessing hard.
Turn on Double points in the last round so people at the bottom still have a shot.

Ask about what you just covered, then have students guess how many classmates got it. Even students who didn't know the answer can score by guessing well, so nobody sits out.
The real count shows you instantly which ideas the class has and hasn't picked up.
Attach a link to a question; it appears only on the result screen, so you can point to further reading after the reveal.

Use Host only with the Streamer timers (60s to answer, 40s to guess) so viewers aren't cut off by stream delay.
Capture the big screen in OBS. The join QR code and room code stay in the corner, and viewers join without installing anything.
Up to 300 players per room; the result shows the closest guessers.

Write questions about the couple or the guest of honor. Just asking "Where did they get engaged?" and guessing how many guests know is enough to get the room going.
Turn on sound on the big screen for a drum roll and fanfare at every reveal.

Talk during the guessing phase. "You didn't know that one, did you?" is half the game.
Easy questions are secretly the best. When everyone assumes everyone knows, one wrong answer throws every guess off.
Keep the practice round on for the first game. Playing one round beats explaining the rules.
