AV Kyuukyoku Mahjong 2 is an unlicensed adult mahjong simulation developed by Hummer Team and released by Ge De Industry in 1995. This 1-on-1 competitive mahjong game challenges players to defeat computer opponents using traditional Japanese rules. Players start with a point total and must win hands to drain their opponent's points. Success in the game rewards players with unlockable adult-themed graphics. Originally based on a PC Engine title, this NES version is a notable example of late-era unlicensed development focused on mature audiences.
