Happy Families is a traditional British card game usually with a specially made set of picture cards, featuring illustrations of fictional families of four, most often based on occupation types. The object of the game is to collect complete families, and the game is similar to Go Fish and Quartets. In Germany and Austria, the game is known as Quartett or Ablegspiel (in Upper Austria and Styria) and is not restricted to sets of four people, but covers other topics such as farm animals or tractors. The game can also be adapted for use with an ordinary set of playing cards.
