Super Double Yakuman is a competitive four-player mahjong game from Imagesoft and Vap Inc., and part of their Double Yakuman series of mahjong simulators. A double yakuman is the name of a very valuable (but rare) hand, usually the sort of once-in-a-lifetime hand that would instantly win the game. The game was followed with a sequel: Super Double Yakuman II. It is the successor to the first Double Yakuman which was released on the Game Boy in 1993.
