Just One is a cooperative party game for 3 to 7 players, designed by Ludovic Roudy and Bruno Sautter and published by Repos Production in 2018.

Just One won the 2019 Spiel des Jahres award for the best board game of the year.

At the start of each round, a card is drawn from the deck to be placed in front of the guesser, facing towards all other players.

The guesser then says the number from 1 to 5 to determine which hidden word other players must give a clue for.
