Each player draws 4 cards that they place face up in front of them. Cards are either "Win", "Lose" or "Last cards. Then, each player takes turns playing a card onto either the left or right side of the playmat.
When you play a card that matches the top card on the left pile, you will either win or lose -- depending on which card is at the top of the right pile!
Last cards can only be played on the left pile. When they are at the top, the condition becomes playing the last of all 8 cards for the round.
