How do you play the 21 card game?

To play the 21 card game, also known as Blackjack, players aim to have a hand value closer to 21 than the dealer without going over. Players are dealt two cards and can choose to "hit" to receive another card or "stand" to keep their current hand. Aces can be worth 1 or 11 points, face cards are worth 10 points, and numbered cards are worth their face value. The game continues until all players have finished their hands, and the dealer reveals their hand. The player with the closest hand value to 21 without going over wins.
