Genetic Roulette

So basically it's the act of serveral men (no specified amount) all ejaculate into one bucket, which is then stirred together. Then with a willing woman, she is given the "genetic surprise", and then after her 9 months of pregnancy in which all of the men were dreading and anticipating, they take a DNA test to see who the baby belongs to. The person who is deemed the father then "loses", and is therefore legally obligated to care for the woman and child, and is not allowed in following rounds (unless they are a betting man). Continue on without the loser until there is one person remaining, the true winner of Genetic Roulette. Keep in mind, everyone should give consent to this. The reverse of the game can be done too, where if several men are all in love with the woman, whoever gets her pregnant first is them the winner, as if a way to choose her partner.

She said she's willing, who's ready to play Genetic Roulette?
