An intense competition that spans over roughly nine months. A group of men ejaculate into a cup and afterwards the mens' semen is mixed. A female volunteer is then inseminated by the mixed semen and nine months later when the volunteer gives birth, the baby's physical appearance as well as DNA(to be certain) is compared with each of the players. The player who is the baby's father is the winner.

Note: For optimal results, players of different races are recommended.
