Trivia, but your team writes the wrong answers

Big Bluff puts a weird-but-true fact on the big screen with one word missing: "A group of flamingos is properly called a ___." Every team writes a believable lie. The lies and the one true answer land on the wall together, and the whole room votes on which is real.

It runs in the browser on phones, no app. The classic show takes about 30 minutes. It's a calm, funny game full of surprises: nobody races a buzzer, you have 90 seconds to think of a good lie, and the best moments come when the answers flip over and show who wrote them and who fell for them.

Write a lie. Find the truth. Get paid for both.

Every lie gets an author

• Lies that fooled nobody flip together in one fast batch.
• Then the lies that fooled someone flip one at a time, the most believed last, each with its author team and the teams it fooled.
• The truth comes last, on a green slide.
• If a team accidentally writes the real answer, the card comes off the wall and the team gets a TOO TRUE bonus.

Points: +100 for finding the truth, up to +250 for fooling others, scaled by the share of the room you fooled. That means it works the same with 6 teams or 16. The last question counts double.

Who it's for

Office parties, conferences, galas, pub nights and school events (14+). Use it when you need 30 minutes with a room that half-knows each other: after dinner, between talks, or as the main act.

How it plays

• Players join by QR code or link on their phone. They enter a name (up to 10 characters) and can add a selfie, but don't have to.
• Prompt (8 s): the fact with its blank appears on the projector.
• Write (90 s): everyone in a team types their own lie, teammates upvote, and the top one goes to the wall.
• Vote (60 s): everyone picks what they think is true. You can't vote for your own team's lie, and the team's vote is whatever most of its members picked.
• Reveal and scores: the host taps through it.
• 8 questions in the Classic show, or 4 in the Short show. Then come the awards (Best Liar, Truth Sniffer, Most Gullible, Lie of the Night) and the podium.

Built for the organiser

1. Open the host view on your laptop and the presenter view on the projector.
2. Pick Classic or Short show, the number of teams (4 to 16) and the timers.
3. Let the room scan the QR code. Teams form in the lobby.
4. Press Start. Run the reveal from the Remote, a phone-sized control with one big button and nothing on it that can end the game by mistake.

Behind that:

• 300 ready-made questions (in English), each with a source note only you can see. Preview them all with their answers, swap any question into the show, or hide the ones you don't like.
• Your own questions: type a fact, the answer and at least 4 lies by hand.
• Moderation is automatic. You can also turn on a pre-screen that lets you check the wall before voting opens.
• If a team writes nothing, "The House" fills the gap with its own lie.
• The room's interface can be switched to one of 28 languages.

What it does to a room

It keeps a room relaxed and curious instead of loud and competitive. Nobody sits out: every player writes, and teammates argue over which lie to send. The quietest person at the table can write the lie that wins the night. Your colleagues also find out who lies convincingly, which is more useful than you'd expect.

It needs a big screen and someone to run it, because the reveal is the show. It isn't for two people at a kitchen table. Running it remotely? Share the presenter window on Teams or Zoom.

Big Bluff is the bluffing game in the Games for Crowds library. If you'd rather have jokes than lies, Punchline Battle plays the same write-and-vote way.
