The Atlantic City game is one of the most popular variants, as the rules are the most favorable to players, with a house edge of 0.36%. The game uses 8 decks and offers players the chance to surrender, and the dealer has to stand on all hand totals of 17-21.
European blackjack has a slightly higher house edge of 0.62%, but remains very popular at casinos online. Players can double down after a split, though remember that if the dealer has blackjack you will lose your total bet in this variant.
This variant gives players the opportunity to place pairs side bets in order to further increase their winnings. These can be placed on either the player or the dealer’s hand, and include mixed pair, color pair and perfect pair.
The surrender rule in blackjack allows players to fold their hand and receive half of their bet back. It can benefit you if you get a very bad starting hand, reducing the house edge 0.07-0.09%, but should be used in those circumstances.
A more recent variant, blackjack switch sees players receive 2 hands at the start of the game, with the option to switch the best two cards between them. The other significant difference is that a dealer's hard 22 is considered a push (tie).
