'Participate in a strip hanafuda tournament or individual battles. Each option presents you with different girls to play against, for a total of sixteen girls. Characters seem to have their own unique special powers to use to their advantage during or before play in tournament mode. Meters indicate the characters points: how much the difference is between the winner and the loser determines how many NP the loser is docked at the end of each round. At one-third intervals of her NP bar, the character has to strip; depleting her bar completely strips her naked and declares her the loser. In individual play, however, only the girl you play against has her bar sectioned off; you simply lose if your bar is depleted'.
