It has collected multiple awards and nominations including the Jeu de l'Année prize in Cannes in 2014.

The official rules state that the game is played with teams of two players each.

Each card has three difficulty levels (blue, red and black) with three concepts each.

The team then places a green question mark on the picture illustrating the main category of the concept.
