The dealer makes two clear cards for each player with the card facing up; two cards are dealt to himself, the card is face up (called the clear card) and the card is face down (called the dark card). The calculation of poker points in everyone's hands is: K, Q, J, and 10 cards all count as 10 points. A cards can be counted as 1 or 11 points. If A counts as 11 and the sum is greater than 21, then A counts as 1 . All other 2 to 9 cards are based on their original face value. First, the player starts to ask for a hand. If the first two cards the player receives are A and 10 cards, they have Blackjack. At this time, if the dealer has no Black Jack, the player can win 2 times. Stake (1 pay 2). If the dealer's clear card has an arrogance A, the player may consider buying or not buying insurance, and the amount is half of the gambling fund. If the dealer is a blackjack, then the player takes back the insurance money and wins directly; if the dealer has no blackjack then the player loses the insurance and continues the game. Players without Blackjack can continue to hold cards, and they can freely choose how many cards they want. The goal is to get as far as 21 o'clock. The closer the better, the better is 21 o'clock. In the course of a draw, if all the cards add up to more than 21 points, the player loses - called Bust, and the game is over. If the player does not blow up and decides to no longer need a card, the dealer opens his dark card. If you don't take cards at 17 o'clock or 17 o'clock, you may not take cards at 15 to 16 o'clock or even 12 to 13 o'clock, or continue to take cards at 18 to 19 o'clock. If the bankrupted, he would lose. If he does not explode, then he will compare with him and win. The kind of point is a draw, and you can get your bet back.         If you hold a card with 5 cards in hand and the total number is less than 21 points, then this situation can suppress the card type (of course, 5 cards add up to 21 points better), but some games do not support it. This rule.
