TRUT (pronounce [tÊy(k)]) is a traditional French bluff game featuring 32 cards with values â€‹â€‹from 1 to 8. Highest value wins. It's a 2 or 4 player game (2 teams of 2). At the start of each round, each player is given 3 cards with which they must win at least 2 tricks out of 3 to win. With a hand so small, rounds go really fast and sometimes they even last only a few seconds.

The detail that makes the charm of the game lies in the announcement "Trut!” which is done verbally or by clapping a hand on the table. At any time in the round, as long as a player holds a card in his hand, whomever "Truts" simply announces to the opposing team he is certain to win the round. Of course, he can bluff. He's got 2 options then: to give up or take up the challenge! Knowing that winning a "Trut" can lead to a greater... or to a huge loss.

A game lasts between 5 and 10 minutes, but the pace is really fast, and the game is so addictive that players often easily play several games.

In 2017, Robin Red Games released a version of TRUT which adds a bunch of cards with special effects.
