Neutralize your opponent - There are three layers of Card games. Bottom one is yours, middle one is neutral and top one belongs to your opponent. You need to cover neutral cards with yours one. Probably they belong to same suit i.e ace with ace, heart with heart with you having a higher number. After your turn, computer will play next and whoever covers the maximum cards wins the game.
You can also pass the cards if your cards are lower or do not match any of neutral cards. As you win, you would see more of girl nudity. Finally, she gets all naked to reward you with a mind blowing erotic performance.
Play this game as it is quite funny plus addictive.
