Mahjong Sailor Wars (Japan set 1)

Nichibutsu’s Mahjong Sailor Wars arrived in arcades in 1993 as an expansion on their earlier Mahjong Triple Wars series. This two-player game combines traditional mahjong gameplay with characters drawn from a popular Japanese franchise. Two players face off, using a specialized keyboard to match tiles and strategically disrupt their opponent’s progress toward completing hands. The title, which translates to “Mahjong Triple Wars Extra Chapter - Sailor Wars,” represents a significant departure for the series due to its mature content. Gameplay revolves around the core mechanics of mahjong—matching sets of tiles—but with an unusual thematic twist centered on the aforementioned characters. A version known as "Mahjong Triple Wars Bangai-hen - Sailor Wars R: Medal Ninatte Return!!" was later released, indicating a potential adaptation for a different arcade format. Powered by Zilog Z80 processors and utilizing a Yamaha YM3812 sound chip, Mahjong Sailor Wars offers a distinctive audiovisual experience within the tabletop genre. The game’s technical specifications include a horizontal screen resolution of 640 x 240 pixels with a refresh rate of 60 Hz and a palette of 256 colors.
