"Take turns laying down cards and trying to think of a character, famous or not, who fits the description being built up on the table. Be aware that at some point, you'll have to justify yourself. The goal is to get rid of all your cards." - Unofficial translation of the French description by the publishers

Each player starts with a hand of 6 descriptive cards, each including an adjective or a clause that may qualify someone (e.g. "American", "is less than 40 years old", "is a Céline Dion fan"...). The first player to run out of cards is the winner.
At the beginning of a round, a descriptive card is drawn face up. Then, each player at their turn must complete the face up card(s) with a single card from their hand, so that the description of someone made of all cards at play builds up on the table. When playing a card, each player should think of a character/person that would fit the overall description (including their own added card). They should keep the identity of this character/person secret. Special action cards may also be played, for example to remove some cards played earlier. If they do not wish to play a card from their hand, they may draw cards until they find one to play. After playing a card, their turn ends and the player on their left is next.
Players continue to play cards on their turn until a player confronts the last person who played a card by saying "I don't know who that is". Then, the person being challenged must reveal the identity of the character/person they were thinking of (or otherwise reveal that they were bluffing!). The challenged player must argue why this character/person suits the description laid out by all the cards at play. If the majority of the players are convinced that the person/character fits the description, or if the explanation of the challenged played makes the challenging player laugh, then the challenged player wins the confrontation (or otherwise the challenging player wins it). The player who lost the confrontation draws new cards to add to their hand, as many as the number of cards played this round divided by 2 (and rounded up).
After resolving a confrontation, a new round begins, starting with the player on the left of the last person who played a card. The game stops whenever a player gets rid of all their cards and thus wins.
