Blackjack Gameplay

Rules

Cards

Six decks without joker are used in the game, which is 312 cards.

Object

Try to beat the banker by getting as close to 21 as possible without going over 21.

If go over 21, players bust and lose to the banker.

Card Values

Every card has its value:

for 2~10, cards are valued at face value;

for face cards (Jacks, Queens and Kings) , they are worth 10 points each

for Ace, it is worth 1 or 11 points, whichever is preferable to the player/banker.

In detail, if counting any Ace as 11 points will make the hand go bust, all the Ace is worth 1 point.

If counting one Ace as 11 points will not lead to bust, the Ace will be worth 11 when compared to player/banker.

For example, value of the hand(A,8) is 19, although Ace can also be worth 1, but 11 is preferable to the player/banker

Value of hand(A,7,J) is 18 as the Ace can only be worth 1 point, or the hand will bust with Ace valued at 11 points.

Comparison

Blackjack>21pt>20pt>……>2pt>Banker Bust>Player Bust

A tie will happen if the banker and player get the same points no more than 21 or Blackjack from the beginning.

Shuffle

Before the card is dealt with, the system shuffles the card by default and generates a private key composed of a series of hexadecimal digits. The player can use the private key to trace the fairness of the card. The player can also choose to reshuffle to get the latest private key.

Initial Cards

For the first card, the dealer gives one card face up to the player, and then one card face up to the banker. For the second card, one is dealt face up to the player and then one is dealt face down to the banker. Thus, player receives two cards face up, and the banker receives one card face up and one card face down(hidden card).

Blackjack

Banker/Player gets Blackjack with two cards worth 21 points, that is an Ace and a ten-value card(10/J/Q/K). Blackjack is bigger than other cards worth 21 points, for example, hand(A,Q) is Blackjack, so it is bigger than hand(6,7,8). After the banker and player get the initial cards and the player has decided whether to buy the insurance, the dealer will first check whether there is a Blackjack. When there is a Blackjack, the system will automatically determine the result as follows:

Banker Blackjack, player Non Blackjack, the banker wins, the player loses the bets;

Player Blackjack, banker Non Blackjack, the player wins and has a Blackjack payout of 3:2;

Both the banker and the player are Blackjack, a tie happens and the bet is returned to the player.

Hit

If Blackjack does not exist in the initial cards, the player can start to choose whether to Hit or Stand.

Allow to Hit: The current total points are less than 21 points (maximum 20).

The player first decides whether to Hit or Stand according to the points of his hand. If the player decides to Hit, the system gives another card to the player. If the cards are worth over 21 after the Hit, this hand goes bust and the player loses the game; if the cards are exactly worth 21, it will automatically Stand; if the cards are worth less than 21, the player can continue to choose whether to Hit or Stand until reaching 21 or bust beyond 21.

After all the hands of the players Stand or Bust, banker turns over the hidden card and starts to choose whether to Hit or Stand.

Total point<17, Hit; 17<=Total point<=21, Stand; Total point>21, Bust.

But banker will Hit on Soft 17, which means If counting one Ace as 11 points will lead to 17, banker will also Hit.

Note: If it does not need to compare the points to know the result, for example, if the player goes bust , surrenders, or gets Blackjack (Blackjack after Splitting Pairs ), banker can only turn over the hidden card.

Stand

When the current total points are less than 21 points, the player can Stand at any time and wait for the banker to operate. After the points reach 21, it will Stand automatically.

Bust

When the current total points are over 21 points, it goes bust. When the banker and the player go bust at the same time, the banker wins, and the player will lose all the bets.

Double Down

Double Down is a special Hit only for the player. When the player has two cards that are worth 9 to 11 points and thinks that he can win the banker's hand with the third card, the player can choose Double Down and the bet will also double. When Double Down, the player will get one more card and Stand automatically. (Note: Double Down is only available when the player has the initial two cards in hand and the player cannot Double Down after Splitting Pairs.)

Surrender

When the player has two cards in his hand, he can choose to surrender and lose half of the bet. There is only one chance for the player to surrender(Player can surrender separately after splitting pairs), surrender is not available after Hit. (Note: Surrender is only available when the player has the initial two cards in hand and the player cannot Surrender after Splitting Pairs.)

Split Pairs

If the player gets a pair (two cards with exactly the same points) for the initial cards, he can choose to Split Pairs, that is, to make a bet equal to the original bet and the two cards are divided into two hands for the player to operate. The bet per hand is the same as the original bet. For two-Ace pairs, after getting one card all two hands will Stand automatically. In other cases, after getting one card all two hands can Hit or Stand, but players cannot Resplit Pairs. Double Down or Surrender.

Note: The Blackjack that appears after Splitting Pairs is also larger than other cards worth 21 points. If the player wins with the Blackjack after Splitting Pairs, the player can only have a payout of 1:1.

Insurance

For the initial cards, if the banker's face-up card is Ace, the player will get the opportunity to buy insurance, which is half of the initial bet amount.

Insurance is a side bet. It only bets on whether the banker gets Blackjack. Insurance will settle when checking whether there is a Blackjack. Insurance settlement does not affect the normal subsequent settlement of the initial bet.

If the player chooses to buy insurance:

If the bank does get Blackjack, the player will have a 2:1 payout of the insurance bet; (for example, initial bet 2, insurance 1, win 2:1 payout of the insurance bet 2, and reclaim the insurance bet 1, so when the banker get Blackjack and the player doesn't get Blackjack, the player does not make any money and gets bak 3.)

If the banker does not get Blackjack and the player wins the banker, the player will normally have 1:1 payout of the original bet and lose the insurance bet. However, if the player also loses to the banker, the player will lose all the bets.

If the player does not choose to buy insurance:

The banker gets Blackjack. When the player does not get Blackjack, the player loses all bets.

The banker does not get Blackjack, player and banker start the process of Hit and Stand as before.
