Ojanko Club (Japan, Program Ver. 1.3, set 1)

Ojanko Club is a two-player tabletop game released in Japan by V-System in 1986. This arcade title offers a digital take on the classic strategy board game of mahjong, challenging players to skillfully arrange tiles and outmaneuver their opponent. The game’s name translates from Japanese as "Mahjong Girl Club," hinting at its visual presentation. Players engage in matches against one another, aiming to form valid sets of tiles according to established mahjong rules. Using the cabinet controls, each player draws and discards tiles, strategically building combinations while observing their opponent's moves. The game combines elements of chance with tactical decision-making as players attempt to be the first to complete a winning hand. Ojanko Club utilizes a Zilog Z80 processor for its gameplay engine alongside sound chips that deliver audio cues and effects during matches. It provides a straightforward, competitive experience rooted in traditional tabletop gaming.
