Orange Club - Maruhi Kagai Jugyou (Japan 880213)

Daiichi Denshi’s Orange Club - Maruhi Kagai Jugyou is a two-player tabletop game released in Japan in 1988 that puts a unique spin on traditional mahjong gameplay. Players engage in matches against each other using a specialized keyboard designed for the intricacies of the tile-matching mechanics. The game features eight distinct female characters, and each character presents three different strip sequences to be matched during play. Orange Club's subtitle, translating roughly to "Secret Extracurricular Lesson," hints at the adult-oriented nature of this arcade title. While retaining the core rules of mahjong, it offers a gameplay experience intended for mature audiences. The game utilizes a Zilog Z80 processor and General Instrument AY8910 sound chip to deliver its audiovisual presentation on a horizontal screen with a resolution of 512 x 224 pixels. A version known as "VIP Club - Maru-hi Ippatsu Kaihou" exists, but the original Orange Club remains a distinct title within Daiichi Denshi’s catalog.
