25 couples and a "panel of experts" were asked for giving their opinions about 32 sex positions. Each of those positions have been categorized in five classes: - Fun factor She - Fun factor He - Injury risk - Back seat suitability - Porn factor The game is played according to the standard Quartett rules: A player plays out a card and chooses a specific category. He names the number on his card. If he has a higher number than the opponent, he wins the card, otherwise the opponent will get the card (except for back seat suitability, where the lowest entry wins). The player who manages to get all 32 cards this way, wins the game.
