From the back of the box: "Here's a fast & fun CARD VERSION of the game kids have played for generations. Each player lays down a card. If your card beats your opponent's card, you take it. When all cards have been played, the player who has collected the most cards wins the game!" The game consists of 54 cards. Each player starts with a hand of five cards and draws a card each time a card is played. So your choice (Rock, Paper or Scissors) is limited to the cards you have in hand.
