A mulligan is a second chance to perform an action, usually after the first chance went wrong through bad luck or a blunder. Its best-known meaning is in golf, whereby a player is informally allowed to replay a stroke, even though this is against the formal rules of golf. Mulligans may not be used at any Hole-In-One, Closest to the Pin or Longest Drive Contest (tee shot) or in the putting contest. A maximum of three Mulligans may be purchased per golfer.
