There are many strands of Blackjack, played all over the world. However, these are usually based on one of two main variants: European or American. Although the rules are the same, it is crucial to know the small differences, as they can affect the gameplay.
European Blackjack

This is a unique Blackjack variant that follows similar rules to classic Blackjack. However, the negotiation process is different. It is typically played with 6 decks of cards. Although, there are also variants with 4-8 decks. If the dealer hits a Blackjack, the player loses their total bet.
Live dealer Blackjack

This version is exactly what the name implies, a live dealer version of Blackjack. In this version, you can see the cards being dealt and interacting with a dealer, making the game incredibly dynamic.
Atlantic City Blackjack online

Atlantic City Blackjack offers its own twist on the classic version of the table game. If played with optimal strategy, this type of blackjack has an advantage of 0.36%. It also allows for the late “surrender” option.
Vegas Strip Blackjack

Vegas Strip Blackjack is another variant of standard blackjack, which retains most of the original rules. These specific rules are: when playing 4 decks, players can double up on any starting hand. However, Aces can only be split once.
Progressive Blackjack

The principles of progressive blackjack are the same as in the classic version.
The main difference between this version and the others is that in progressive Blackjack the game features progressive jackpots, which increase after each play.
Change it 21 Blackjack online

One of the newest variants of blackjack, Change It 21, is played with 6 decks of cards. The main difference between Change It 21 and regular blackjack is that the player has the option to replace one of their first two cards, within the "Change It" feature. This action has a cost of 50%, under the value of the initial bet.
