Jantei Monogatari — About this game
A private investigator searches for a kidnapped girl by combining a menu-driven mystery with mahjong matches. People who know something about the case are not always willing to speak freely: winning at the table encourages them to reveal another part of the story. At first, only a small group of potential contacts is available, but information gained from those opponents opens more enquiries. The game therefore alternates between choosing where to investigate and building a winning hand. Read the dialogue after each match, since its reward is a lead rather than simply a score. Approach the mahjong patiently, keeping a plausible hand together instead of discarding at random just to return to the next conversation.
