In Dixit, 3 to 6 players have hands of oversized cards with various artistic pictures. The active player secretly selects one of his cards and gives a very brief description. The other players secretly select their own cards which match the description. The chosen cards are shuffled and revealed, then players vote on which was chosen by the active player. Each correct answer gives points to the guesser and the active player. Each incorrect answer gives points to the player who submitted the guessed card. However, if all of the guesses are correct — or none of them are — then the active player gets no points and all the other players get points. The game ends when the deck is empty. The greatest total wins the game.
Here is some information on playing the game.
