Yakyuken is a Japanese variation of Rock-scissors-paper wherein the loser of each round removes an article of clothing. Yakyuken gets its name from a Shinboku chant associated with the non-adult version of the game. It became a part of porn culture in Japan, and other Asian countries after the influence of TV variety shows and Soft On Demand. Numerous Hentai games have been made featuring the Yakyuken gameplay, and several American studios, such as Lost Bets Productions, focus on the filming and marketing of Yakyuken and other related strip games.
As a pun, rock-paper-scissor (野球拳) became a martial arts skill in the Chinese game 金庸群侠传 jin-yong-xun-xia-zhuan "Heroes of Jin Yong". In the game, the highest attainable level for 野球拳 is the most powerful martial arts skill in the game, however to training the skill to the highest level is a vapid task.
