Natural selection, the card game

• Take two packs of 52 cards - pack A and pack B
• From pack A spread out all the hearts and clubs

Repeatedly

• Shuffle pack B and deal one card
• If it's a red card add a red card from pack A to the spread out cards
• If it's a club add a black card from pack A to the spread out cards
• If it's a spade try again
• Return all the dealt cards to pack B
• Shuffle pack B and deal one card
• Remove a card of the corresponding colour from the spread out cards and return it to pack A
• Return the dealt card to pack B

The game ends when the spread out cards are all the same colour.

This game implements the Moran process. The probability that the red cards reproduce is twice that of the black cards. They both have the same chance of dying.
