The aim of the game is to collect as many quartets (four cards that belong together) as possible. Once a quartet is complete, it is discarded. The winner is whoever has collected the most quartets at the end.
Question/answer variant: The process is similar to the normal rules of the game, with the difference that the questioner is only given the desired card if he or she can correctly answer the question related to the composer. The solution to the question is the composer indicated on the card.
