As with most other Mahjong simulators, this is an accurate portrayal of the classic Chinese board game, complete with detailed tiles and animated character portraits. It is four player, though two players are obscured by the sides of the screen (the player can move the camera to see their tile walls, but not the tiles themselves). As per usual Mahjong rules, the first player to put together a winning hand - either from the tiles they collect at the start of each turn or the discarded tiles of other players - wins the game.
Though a Mahjong game set during the Warring States period was nothing new at the time, Sengoku Mahjong has the honor of being the first Mahjong game made for the Turbografx-16 system. As might be expected, it was never released outside of Japan. It was, however, rereleased on both the Wii's Virtual Console and PSN, in 2007 and 2009 respectively.
