chơi bài xì dách trên facebook

　　As an AI language model, I am not capable of playing games on Facebook or any other platform. However, I can provide you with the basic rules of playing Xì Dách (Blackjack) if that helps.

　　Xì Dách is a popular card game that is played with a standard deck of 52 cards. The objective of the game is to have a hand value closer to 21 than the dealer's hand value without exceeding 21.

　　Here are the basic rules:

　　1. Each player is dealt two cards face up, and the dealer is dealt one card face up and one card face down.

　　2. Players can choose to "hit" (take another card) or "stand" (keep their current hand).

　　3. If a player's hand exceeds 21, they lose automatically.

　　4. Once all players have completed their turns, the dealer reveals their face-down card and hits until their hand value is at least 17.

　　5. If the dealer's hand exceeds 21, all remaining players win.

　　6. If the dealer's hand value is closer to 21 than any player's hand value without exceeding 21, the dealer wins.

　　7. If a player's hand value is closer to 21 than the dealer's hand value without exceeding 21, they win.

　　There are additional rules for splitting pairs and doubling down that can vary depending on the specific version of Xì Dách being played.

　　I hope this helps!
