Sevens, also known as Laying Out Sevens, Fan Tan, Crazy Sevens or Parliament, is a card game for 3–7 players using a standard deck of 52 cards. Cards are played out to form a layout of sequences going up and down in suit from the sevens (as in many solitaire games). The game is won by emptying one's hand before the other players.
