Game: Mahjongg
Difficulty: 3
Nudity: 3

A mahjongg game with plenty of animation and voice. You play the part of a student who is often challenged to mahjongg matches as he wanders the town; when facing girls, indicators measure how many rounds each player must win and a meter fills to a certain degree depending on the worth of your mahjongg. You must fill this meter at least to the middle section in order to see the girl's full strip scene; otherwise she will only undress as far as her bra and panties. The game often gives good hands to both you and your opponent, though you have to start over from the beginning of the match if you lose and chose to continue. A couple of sequels followed this game.
