Every online casino offer bonuses and promotions to entice new players to try their games.

• You might only need to play 30 times the bonus and deposit amount if you play slots but 10 times that if you play blackjack.
• Bonuses usually restrict your ability to cash out until you clear the bonus by meeting the clearing requirements.

There are many different blackjack game variations, some of which include:

Basic Blackjack Strategy

Online blackjack is played with a deck of cards, or a number of decks, each containing exactly 52 different playing cards. The set nature of the card values means that every card that is played leaves an exact number of cards remaining in the deck. For example, if the Ace of spades is removed from a single deck of cards you know that it’s not possible for another Ace of spades to be played until it gets shuffled back into the deck.

The reason this is important is that when you’re dealing with an exact set of cards you can develop mathematical models that tell you what the best possible play is in every situation at the online blackjack table. This correct mathematical model is called the basic blackjack strategy. You don’t have to figure out any of the math, it’s already been done by others. All you have to do is follow the advice to benefit from it.

Every play is based on the cards in your hand and the up card the dealer is showing.

When the correct math and computer programs are used it looks at the same situation based on every single way it can turn out in the long run. Many computer programs run simulations millions of times to see which play is the most profitable. Sometimes two plays are profitable, but one is always more profitable on average than the other. At the time every possible play is unprofitable, but one play will be less unprofitable than the others.

Here’s a blackjack strategy chart you can use. You should print it out and use it while playing, or simply have it ready when you play blackjack online. Often you can find small cards with basic online blackjack strategy at the online casinos you play at. For those that play online and use this chart, you’ll quickly memorize the best plays and eventually stop using the chart.

We’ve color-coded the chart to make it easier to read:

• Hit simply means hit or take a single additional card. It’s color-coded green because green means go.
• Double means to double down. Simply slide an extra bet equal to your first wager out.
• Stand means stand or take no more cards. It’s color-coded red because red means stop.
• Split means split. Put your cards side by side and slide an additional bet the same size as your first bet forward.
• The H stands for a hard hand. An H5 means a three and a two.
• The S stands for a soft hand, so each one includes an Ace counted as 11. If you have a hand with the Ace counted as one, you have a hard hand.

You need to learn additional rules for games that have surrender as an option.

The following adjustments need to be made if you aren’t allowed to double after splitting.

The only other main strategy concern you need to know is you should never take insurance. As you read in the opening section, taking an insurance bet is basically betting on whether or not the dealer has a 10 valued card in the hole. If the dealer has a 10 you win 2 to1 and with any other card, you lose.

The deck has 10’s, jacks, queens, and kings as 10 valued cards. The cards that aren’t 10’s are aces, twos, threes, fours, fives, sixes, sevens, eights, and nines. So nine card ranks make you lose and four card ranks make you a winner. This makes the odds 9 to 4, but only pays 2 to 1. 2 to 1 is the same as 8 to 4, so you can see that 9 to 4 odds are worse than the 8 to 4 odds, making insurance a losing bet.

It is vital that online blackjack players learn how to manage their bankroll. If you lose all of your money in one gaming session, you won’t be able to win back your money. This is why learning to manage your money is important. You can check out our guide to bankroll management to help improve your gameplay. Remember, no money = no blackjack betting.

Live Dealer Blackjack

Were you aware that you can play online blackjack with a real dealer almost exactly the same way you play at your local casino?

Using video streaming technology, many online casinos offer live dealers, usually attractive females in skimpy outfits much like in many real casinos, who deal on the camera. Once you log in and get started it’s easy to forget you’re playing online instead of at a big casino resort in Las Vegas.

Not every online casino has live dealer play, so check the reviews we offer or look for the live dealer section on the individual casino websites linked to from this site.

Mobile Blackjack Games

Technology is always improving and making things that seemed impossible only a few years ago normal. One of the most amazing technological advancements over the past several years is how useful mobile phones and other devices have become.

You can play a game of blackjack on your smartphone or tablet from almost anywhere. And we’re not talking about some watered down version with simple graphics either, but instead a mobile blackjack version that looks and plays just like a regular online casino game. You can play the same blackjack game you play at home on your desktop or laptop computer.

Almost any phone or tablet that uses an Android operating system or an iPhone or iPad has online casinos that offer great blackjack games. Some internet casinos even support Blackberry and Windows based phones.

Simply follow one of the links on this site to an online casino and look for the mobile gaming section of their site. You can download or access the apps directly from the casino website. You don’t want to go to the regular app store or iTunes store. They usually don’t have the best versions and options for blackjack players.

There are three different platforms that you can use in order to play blackjack on your mobile device, whether it is Android, Apple iOS, or even BlackBerry.

Counting Cards

If you’ve been playing blackjack for long and have read anything about the game you’ve probably come across some information about counting cards to gain an edge against the casino and the blackjack tables.

Blackjack players tend to have one of two reactions to this news. They either instantly think that counting cards is too hard so they don’t consider it, or they want to know as much about it as possible so they can start winning money on a consistent basis instead of being a long term losing blackjack player. There are plenty of books on this subject that players can read and get informed.

The good news is that players can get an advantage against the casinos by learning how to count cards. The bad news is you have to play in a live casino to use your skills for profit. You can practice while playing online, but the online games are designed in a way that eliminates the ability to gain an edge by counting.

If you’re one of the players who think counting is too hard to learn, you need to learn more about how it’s done before you sell yourself short. If you can add or subtract one from a single number you keep in your head you can learn to count cards while playing blackjack.

If the count is a positive three and a two is dealt, you add one to your count. Your new count is positive four. If the net card is a king, you subtract one from your count. The new count is three. If the next card is a jack you subtract one. This makes the new count two.

See how easy counting cards at the blackjack table is?

Of course, you need to learn what to do in certain situations based on the count, but if you take your time and have confidence you can do it you can learn to count cards quickly and easily.

But don’t even think about counting cards at blackjack until you have memorized the basic strategy decisions and can make them correctly 100% of the time. Without using the best basic blackjack strategy every single time, you’ll give up too much of an edge to make counting worth learning.

The online casinos have software that shuffles the cards after each hand so even though it seems like you’re working your way through the blackjack shoe you’re playing a new hand every time with a fresh set of cards. Even the live dealer casinos switch shoes often because they know about card counters too.
