Bishoujo Janshi Pretty Sailor 18-kin (Japan)

Published in 1994 by Sphinx, Bishoujo Janshi Pretty Sailor 18-kin is a two-player tabletop game that combines mahjong gameplay with characters inspired by the popular Sailor Moon franchise. Two players face off against each other in traditional mahjong matches using a specialized keyboard for tile manipulation. The game’s title, translating to "Pretty Mahjong Warrior Pretty Sailor," indicates its connection to the well-known anime series and hints at the mature content intended for audiences over 18. The core mechanic involves standard mahjong rules where players draw and discard tiles to form winning hands. A unique element introduces a penalty for losing: the defeated player experiences a visual stripping effect, adding an unusual dynamic to the competitive gameplay. Powered by Zilog Z80 processors and featuring sound chips including a YM3812, the game presents its action on a 640x240 pixel screen with a palette of 256 colors. Pretty Sailor 18-kin was the first installment in a series; a sequel, Bishoujo Janshi Pretty Sailor 2 - H na Sasayaki, followed shortly after its release.
