In the middle of the table in Leg los! (a.k.a. "Go Ahead!"), sixteen tiles show all kinds of things and are each assigned a number from 1 to 16. Each round, one of the players is the "artist", secretly drawing a number that determines which of these things he must build using only long and short sticks and large and small discs, and the other players try to identify the thing he builds.
Leg los! includes several fun elements that make the game more than just a tense recognition race: In addition to having the pressure of a sand timer, the more things that the other players guess, the better it is for the artist. What's more, the artist can't talk, each other player can make only a single guess, and each type of building material can be used only once during your turn. A correct guess rewards both the guesser and the artist, with the players gaining points on a score track. Whoever has the most points at the end of the game wins.
