The reveal is the party
When you start the reveal, every guest's phone follows along: the crowd's split, the right answer, who nailed it, and a leaderboard that builds question by question — so nobody knows who won until the podium. Seven people in seven cities on a call, or forty at a table. A TV is optional.

Questions people ask
- Do guests need to download anything?
- No. The link opens in the browser on any phone. Guests tap their name and play. No account, no app.
- Does everyone have to be in the same place?
- No. Play-ahead is the default: people play on their own time, from anywhere. The reveal runs on every phone at once, so a group on a video call gets the whole show. A TV in the room is optional.
- What does it cost?
- Building, previewing and playing with a few friends is free. The Party Pass ($19, one time) opens one Guessbook to everyone you invite, for good. Refundable until the day of the event.
- Can I fix a question after people have played?
- Yes. Edit anything from the dashboard; results recompute on the spot and you're told how many people that touched.
- Who writes the wrong answers?
- For the built-in prompts, we do. For your own questions, tap “Suggest some” and pick from plausible wrong answers, or write your own.
