Oh! Pai

Oh! Pai is an adaptation of a tile game that has similarities to mahjong, though with much simpler rules. The player competes one-on-one against any of the six young women featured in the game. Each opponent offers a different thematic set of tiles (e.g. a stereotypical shy schoolgirl uses teddy bears, pink clothes, etc.), but the game rules are always the same: form simple combinations of three or more identical tiles to win. After each successful round the girl removed a part of her clothes.
