Bluffo.

Tell the truth, or lie beautifully.

The party game of lying well, around a single phone.

Icône de l'app Bluffo : un B raturé d'une barre rouge

One player draws a card and reads the question out loud. Then the phone goes round the table, and everyone else reads something they aren't allowed to repeat: the real answer. Tell the truth and work in all three red words, or invent something entirely and never let one of them slip. The reader names the one they believe. The card opens.

One card

A question read out loud, a real answer read in secret. Checked facts, never legends.

Three red words

All of them if you tell the truth. None of them if you make it up. The app enforces the rest.

One liar to name

The reader chooses, the card opens. The most convincing player wins, not the most honest.

The game

Only one of them is telling the truth.

No accounts, no wifi. Names stay on the phone, and the phone stays on the table. An ink-and-paper identity with a red full stop for a signature.

The card

Everyone reads the real answer. In secret.

The paper card carries the question, the real answer and its red words. One tap hides the screen when a neighbour leans in. Then you choose: I'll tell the truth, or I'll make it up.

The rule

Three words to slip in. Or never to say.

Telling the truth? Every red word must be in there, phrased any way you like. Making it up? Not one may cross your lips. The truth can only be taken once: the app blocks whoever comes next.

The round

The phone goes round the table.

A hand-over screen between players, with the next name in large type. No one else is looking. The next player confirms it's them before the card is revealed.

The reckoning

Then you have to name a liar.

The reader names the one they believe. Taken in or well spotted: the card opens, everyone reveals what they actually did, and the Point and Question cards change hands.
