Blackjack is a card game with an RTP rate in the highest group among casino halls, ranging from 99% to 99.5%. BGD99 offers many high-quality versions from leading providers to serve all objects. Let’s learn in detail the factors that create the lasting appeal of this legendary game right below.
Introducing an overview of Blackjack at BGD99
Blackjack maintains its top position in casinos thanks to its simple mechanism but requires clear thinking strategy. The game continuously expands its influence from Las Vegas casinos to global online platforms.

History of formation
The game first appeared in France in the 18th century under the name Vingt-et-Un, which means 21 in French. By the 19th century, the game spread to America and was given a special reward by casinos when owning a black Jack card. The name was born from that special reward and gradually became the official name of the game worldwide.
Point calculation mechanism
The point calculation system in the game is designed to be simple and easy to grasp but creates many complex tactical situations. The table below lists the point value of each type of card in the game so you can easily grasp the information:
| Type of card | Point value |
| 2 to 9 | Keep the original numerical value on the card |
| 10, J, Q, K | Calculate 10 points per card |
| Ace | Flexible calculation of 1 or 11 points |
| Natural Blackjack | Ace plus 10-point card immediately on the first turn |
Gameplay objective
The core objective is to achieve a higher total score than the dealer without exceeding 21 points in any situation. Players win when the total score is higher than the dealer’s or the dealer exceeds 21 or the player has a natural 21 points on the first turn. The usual reward ratio is 1:1 for a normal win and 3:2 for a natural 21 points.
Distinct betting actions in a game of Blackjack
Blackjack builds a diverse system of betting actions, allowing players to actively adjust their strategy based on the current combination. Each action has a distinct mathematical meaning that directly affects the probability of winning in specific situations.

Hit and stand
Hit is the action of requesting an additional card to increase the total points, usually performed when the current total points are low. Stand is the action of stopping receiving cards to keep the current total points and waiting for the dealer to complete their turn. The decision to Hit or Stand depends on the total points in hand, the dealer’s upcard, and the standard basic strategy chart.
Double down
Double Down allows players to double their initial bet after receiving the first two cards but only receive one more card. The table below lists the optimal situations to perform Double Down according to the basic strategy at the BGD99 system:
| Total points in hand | Optimal conditions for Double Down |
| 11 points | Dealer exposes any card from 2 to 10 |
| 10 points | Dealer exposes a card from 2 to 9 |
| 9 points | Dealer exposes a card from 3 to 6 |
| Soft 16 to 18 | Dealer exposes a card from 4 to 6 |
Split
Split allows splitting two cards of equal value into two separate sets, each continuing to play independently. Below are situations that should or should not be split according to the basic strategy at the BGD99 system:
- Always split Aces to create an opportunity for a natural 21 points in both sets of cards.
- Always split 8s because a total of 16 is the weakest point, and splitting will increase the probability of improvement.
- Do not split 10s because a total of 20 points is very strong, and there is no need to take additional risk.
- Do not split 5s because a total of 10 points is more suitable for Double Down than Split in this situation.
