ZIK Games and Success Corporation announced on July 2, 2026, that a new mahjong game based on Masayuki Katayama's manga 'Gyuwambura Jiko Chushin-Ha' will release for Nintendo Switch in fall 2026. Titled 'Gyuwambura Jiko Chushin-Ha: Doranpu Teikoku o Wakaraseru!', the download-only title is priced at 5,280 yen. Original author Masayuki Katayama is handling new character designs and the story mode script. The game features 22 characters total, including 20 from the original manga and two new characters: Great Doranpu, a self-proclaimed mahjong hustler who rules the mahjong world, and Elon Massug, a tech entrepreneur who leads a future mahjong company. In story mode, players aim to make Great Doranpu understand by winning matches against a variety of unique mahjong players. After matches, players can use the skills of defeated opponents, such as Tako Miyauchi's 'Big Octopus Draw' and Octopussy Fumi's 'Octopussy Sign'. Both story and in-match dialogue are fully voiced. The first half of the story takes place in a prison facility on a remote Okinawa island, while the second half moves to Drump Tower in Manhattan.
The game is published by Success Corporation and developed by Sieg Games and Cosmo Machia. It is a download-only title for Nintendo Switch, with no physical release announced. The two new characters, Great Drump and Elon Massugu, are described in detail: Great Drump advocates for beautiful matches among the strong and declares himself a mahjong hustler, while Elon Massugu runs a company called Lastte that develops gasoline-powered mahjong tables. The story mode is divided into two settings: the Nankuru Prison on a remote Okinawa island in the first half, and Drump Tower in Manhattan in the second half. Players challenge the Drump Empire under Great Drump's philosophy of 'tax on poor mahjong'. Skills from defeated opponents can be used strategically, adding a layer of decision-making beyond standard mahjong. Voice acting covers both story scenes and in-match dialogue, including taunts and reactions. The official website and X account have opened, with further details on release date, game system, characters, and cast to be announced later.
