Thirty-one (card game)

Thirty-one or trente et un is a gambling card game played by two to seven people, where players attempt to assemble a hand which totals 31. Such a goal has formed the whole or part of various games since the 15th century such as commerce, cribbage, trentuno, and wit and reason. 31 is popular in America and Britain.

Although the game is also known as scat, it has no connection whatsoever with Germany's national card game of Skat. It should also not be confused with other games called 31 including Schwimmen (also known as Schnauz or Hosen runter) and the Greek banking game of 31.
