The game’s point calculation rules are clearly defined based on the displayed value of each specific card. The definition of what is blackjack requires users to memorize the standard conversion table below.
| Card group | Defined value |
| Cards 2 – 10 | Calculated by the displayed number of nodes (2 – 10 points), regardless of suit |
| Cards J, Q, K | All three face cards have the same value of 10 points |
| Card Ace (A) | Calculated as 11 when the total is under 21, calculated as 1 when the total exceeds 21 |
Point comparison rules between Player and Banker
What is the goal of customers when participating in Blackjack? Members on the table, collectively called Player, will only compare points directly with the Banker, not competing with each other. Users do not need to care about the cards of others and only need to focus on defeating the Banker.
- Goal: The total points of the cards in the player’s hand should be as close to 21 as possible but must not exceed 21.
- Winning case: Your score is higher than the Banker’s score, or the Banker exceeds 21 points (Bust).
- Losing case: The player’s total exceeds 21, or the final score is lower than the Banker’s score.
- Draw case (Push): The points of both sides are equal, the system will refund 100% of the initial bet to the customer.

Player’s action choices in the game
After receiving the first two cards, participants need to make action decisions based on their current score. The table below will help members understand the detailed command options at the Blackjack table. Customers can use these options to turn the situation around.
| Term | Applicable situation | Action meaning |
| Hit | Total points of the first two cards are low (2 – 16) | Draw another card from the common deck to increase points |
| Stand | The score is already safe (17 – 20) | No more draws, keep the current score to compare |
| Double down | High chance of winning with 10 or 11 points | Increase the bet to x2 and only draw one card |
| Split | When divided into two identical cards (e.g., a pair of 8s, a pair of Aces) | Split into two independent games, place an additional bet equal to the old game |
| Insurance | When the Banker’s face-up card is an Ace (A) | Place a side bet equal to 0.5 times the original bet in case the Banker has Blackjack |
What is the process of a Blackjack game?
The operating process of an online game at the system strictly follows a 2-stage sequence. Customers need to closely monitor each step of the dealer to not miss the opportunity to win the game.
The player places a bet and the house deals the cards
Each game will start with members choosing the bet chip to place in the designated area on the table. The time limit for placing bets at Phtaya usually lasts 15 seconds. After the time is up, the system’s dealer will deal the cards according to the circular standard. The meaning of this first step of the Blackjack game is to create absolute transparency before flipping the cards.
- Dealt to the player: Each member sitting at the table receives 2 cards and both are face up.
- Dealt to the house: The Banker also receives the first 2 cards but only one is face up, the other is face down.

The rounds of drawing cards and determining the final win or loss
The game will start from the player sitting on the left side of the dealer. Customers proceed to choose actions like Hit, Stand, Double or Split until they stop. The determination of the winner at the end of the Blackjack game will be based on the Banker’s mandatory draw rules:
- The house rules: The Banker must draw another card if the total score is under 16 and must stop drawing when reaching 17 points or more.
- Determining the result: The system automatically compares the scores of both sides and pays out rewards in a 1:1 ratio for the usual winning door.
The nature of the final process of the Blackjack game ensures that all members have an equal opportunity to receive rewards. You will receive the money added to your game account immediately when the dealer announces the winning result.
