Jantei Monogatari

Jantei Monogatari combines a whodunnit visual novel with mahjong gameplay. The player takes the role of a private investigator called to a girls’ school after one of its pupils disappears shortly after playing mahjong with three other students.

To uncover the truth, the investigator must question the students and other opponents, then defeat them at mahjong to obtain new clues and evidence. Originally released for the TurboGrafx-16/PC Engine CD in 1990, the game was ported to the Sega Mega Drive in 1991. Atlus developed it, and Renovation Game published it.
