The 5 Best Legal Online Blackjack Sites

The most popular table game without a doubt, blackjack dominates online casinos across the US. Casinos are big fans of the game because blackjack brings in more money than any other table game. That means huge player losses, despite blackjack having the best odds of all table games hand.

One of the few casino games, the house only has a 0.05% edge when a player applies basic strategy. Professional blackjack players beat the game by counting cards. They raise their bets when more high cards are left in the deck, and bet the minimum or leave the table when more low cards are left.

Playing blackjack at the right online casino can significantly influence your results. The five best legal casinos for online blackjack stand out when it comes to payout ratio, game selection, favorable player rules and more. 

Recognizing and avoiding common blackjack mistakes is essential for players looking to excel in online blackjack, where strategic decisions can greatly impact the outcome of each hand. A hand of blackjack begins when a player makes his wager and is dealt two cards, face up except in single and double-deck. The dealer deals himself one card facing down and another card facing up. The player decides whether to hit or stand based on his cards and the dealer’s up card.  He can hit and receive another card as many times as he likes without exceeding 21. When he’s satisfied with his hand, a player can decline additional cards and stand. 

If taking one more card puts him at an advantage, a player should place a new bet next to his original and double down. A player with two cards of equal value can also make a new bet to split the hand. In this case, the dealer separates the cards into two new hands, then deals each a second card. Finally, when available, surrender allows players to forfeit their worst hands in exchange for half their bets back.

Basic Strategy

Basic strategy charts teach players the right moves to make based on their hands and the dealer’s up card. The only way to gain the advantage over the house is to count cards, but consulting basic strategy charts drives the house edge down to 0.05%. Without basic strategy, the house has a 1.5% to 2% edge. Basic strategy charts are available online and in casino gift shops.

Also, it might seem obvious, but remember each spin is independent of all others - don't start believing in the gambler's fallacy while playing. Just because you've won the past five hands, it doesn't mean you've got an enhanced chance of winning the next. 

Does Card Counting Work Online?

We’ve already established that you can’t count cards on virtual blackjack games. However, given the right conditions, card counting is possible if you’re playing a live dealer game dealt from a shoe. Before you pull the trigger, count the number of decks the dealer cuts off before shuffling. If it’s 1.5 or less, that’s considered good deck penetration. That’s hard to find online where it’s not unusual for dealers to shuffle halfway through a 6-deck shoe, keeping counters away.
