Koi Koi Shimasho

'A strip hanafuda game against four schoolgirls. Not very difficult as the girls often wait until the last minute to go out if their hand is worth anything. Although you get a partial strip scene by going out once, you must run them out of points completely to see the full strip and move on to the next girl. Some animation is present, but the strip scenes are only scrolling pictures'.
