How do you play the 31 card game according to the rules?

To play the 31 card game, each player is dealt three cards and the goal is to have a hand value as close to 31 as possible. Players take turns either drawing a card from the deck or the discard pile, and then discarding a card. Face cards are worth 10 points, aces are worth 11, and number cards are worth their face value. The round ends when a player knocks or when someone reaches exactly 31 points. The player with the lowest score loses a life, and the game continues until only one player remains with lives.
