AV Hanafuda Hana no Christmas Eve

AV Hanafuda: Hana no Christmas Eve (AV花札 花のクリスマスイブ) is an adult-themed (AV) Koi-Koi arcade game published in December 1990 by Nichibutsu (Nihon Bussan Co. Ltd.) and developed by AV Japan.

Players compete against computer opponents in standard Hanafuda card matching. Winning rounds rewards the player by uncovering erotic/adult graphics or cutscenes, a common trope for Japanese arcade parlours of that era.
