“Virtual Double Yakuman” is a mahjong game for the Virtual Boy. After Game Boy and Super Famicon, the VB would have got its own version of the “Double Yakuman” series.
The name comes from “Yakumangan”, one of the many bricks in the game, or better said, the “Yakuman” constellation, which plays a central role in the “Yakuman Shoubu Mode”. In this mode you win with a “Yakuman”, which can also be gotten easier.
