Puzzle blackjack card -relax

What is it about?

Rule: Players with the highest number of points win, their points must be equal to or lower than 21 points; players over 21 points are called explosions. The cards from 2 to 10 are added by the number of points on the board, and each of J, Q, and K is 10 points. A can be recorded as 1 point or 11 points. If the player will beep for A, then A can be counted as 1 point. When A in a hand counts as 11 points, the hand is called a soft card, because unless the player takes another card, there will be no explosion. The goal of each player is to get the card closest to 21 points to beat the dealer, but at the same time avoid bursting. It should be noted that if the player is the first to lose the game, then the dealer will be the same. If the player and the dealer have the same points, neither the player nor the dealer will win or lose. The game between each player and the dealer is independent, so in the same game, the dealer may lose to some players, but also defeat other players.
