*Play this card game with a friend:*

- Shuffle the cards and deal them face down to the players in a pile.
- Each round consists of all the players turning over the first card in their pack in an outward motion, giving every player a fair chance of seeing the card as it's turned over.
- When a prime is played, the first player to call out "prime" takes the card and any others that may be in the stack. If there's a tie, the pile should remain in the center and play should continue. If the number turned over isn't a prime number, leave the cards in the center of the table until a prime number appears and the cards are won.
- After a player wins cards, they must shuffle them into their deck before the game can continue.
- Play until one player has all the cards or set a time limit on the game and stop when time is up.
- The player with the most cards at the end of the game wins.
