Whist \Whist\, n. [From Whist, interj.]
   A certain game at cards; -- so called because it requires
   silence and close attention. It is played by four persons
   (those who sit opposite each other being partners) with a
   complete pack of fifty-two cards. Each player has thirteen
   cards, and when these are played out, the hand is finished,
   and the cards are again shuffled and distributed.
   [1913 Webster]

   Note: Points are scored for the tricks taken in excess of
         six, and for the honors held. In long whist, now seldom
         played, ten points make the game; in short whist, now
         usually played in England, five points make the game.
         In American whist, so-called, honors are not counted,
         and seven points by tricks make the game.
         [1913 Webster]

   Bridge whist. See Bridge, n., above.

      are preserved as dealt and played again by other players,
      as when each side holds in the second round the cards
      played by the opposing side in the first round.

   Solo whist. See Solo whist, above.
