21 Card Game Explained. The most important blackjack rule is simple: beat the dealer’s hand without going over 21. If you get 21 points exactly on the deal, that is called a “blackjack.” When you’re dealt a blackjack 21, it’s customary to pay out 3:2 or 2:1. That means you win $300 for ever $200 bet at 3:2, or $200 for every $100 bet.

Every online casino under the sun offers a couple blackjack games, but we know that sometimes you want to play more than just a Vegas-style game of 21. We rate casinos on the variety of blackjack. This Blackjack game features an additional bet '21 + 3'. Not compulsory, it is however interesting if you are looking to win a max in one hit! It will take into account your two cards and the one returned from. Play for pretend chips in this free online blackjack game. How much can you win? To win you the sum of your cards must be closer to 21 than the dealer. Press hit to recieve another card or stand. Blackjack is a simple card game in which players compete against the dealer. The set-up requires the player to build a hand that is stronger than the dealer’s one without going over 21 as the total of each.

Blackjack is a card game that pits player versus dealer. It is played with one or more decks of cards. Cards are counted as their respective numbers, face cards as ten, and ace as either eleven or one (in our game it will show on the counter as an 11 unless you are over 21). The object of Blackjack is the beat the dealer. This can be accomplished by getting Blackjack (first two cards equal 21) without dealer Blackjack, having your final card count be higher than the dealers without exceeding 21, or by not exceeding 21 and dealer busting by exceeding their card count of 21.

In Blackjack, or 21, the player must decide what to bet before the hand. Click the chips to add them to your bet. Click the chip again to remove it back to your pile of money. Once you click 'deal' your bet is set, and two cards are dealt to the player face up and two cards are dealt to the dealer, one face up and one face down. You must then decide if you will 'hit' (take another card from the deck), 'stay' (keep the hand you are dealt), or 'double' (you double your bet and are given only one more card). If the dealer has an Ace showing, you can click the 'Insurance' button (this means you will place a bet worth half your hand bet, which will be paid out if the dealer has Blackjack but will be taken if the dealer does not).

Once the Blackjack hand is played out, three outcomes can occur. First you can win (as previously described), secondly you can lose (bust hand or have less than dealer hand), or you can push (have same hand - number count or Blackjack - as dealer). If you win, you get your bet money back PLUS that same amount from the dealer, YAY! If you win with Blackjack, you get your original bet back PLUS you win 1.5 times your bet from the dealer, WOOHOO! If you lose, the dealer takes your bet money. If you push, you keep your bet money but do not win anything additional.

If you want advice while you are playing, click the Advice button (speech bubble) in the bottom right corner. This will tell you what move will be most statistically likely to win the hand you are holding in blackjack. It will not always win, but it is the best statistical chance you have, so give it a chance if you are stumped!

Keep playing 247 Blackjack until your money is all gone - then restart! No need to wait additional time for more chips! If you are on a streak and need to leave your computer, no worries! Your fabulous money pile will be kept until you return! Just be sure to Resume your game when asked! As you win money watch your chips grow in denominations! Your highest money count will always be kept as your high record too, just so you always have something to strive for!

One of the best things about 247 Blackjack is all the options it comes with! When you are on the home screen (or in the game, push the Menu button - three lines with three dots - in the bottom right to get to home screen - don't worry, you can resume!), click the middle Options button which looks like a wrench. Here you can select the number of decks you'd like to use, whether to auto bet your previous bet, whether a dealer hits on a soft 17 (soft seventeen is where an ace is used as eleven in the dealer's hand), whether you want the insurance option during the game, and whether you'd like auto advice (which turns the game advice on for every hand).

And heads up card readers! Just like in the casinos, the cards will automatically shuffle when you get down to half left, so it'll be a bit harder to read what will be coming out next.

We know you're going to LOVE 247 Blackjack so just give it a go! Have a great time using your skills and a little good luck to enjoy the best Blackjack game around!

  • Never play the Insurance button, it is a a loser's bet.
  • Almost always hit until you reach seventeen, especially if the dealer has a seven or higher.
  • If the Blackjack dealer has a four, five or six, don't take any chances! They're most likely to bust. Double your hand in these circumstances if you surely won't bust.
  • Turn on the advice in the bottom right corner for tips just like these!

This is our first blackjack game and trainer and I'm proud to finally add our version 2 with enhanced graphics and the ability to learn how to count cards to my website. The game is mostly self-explanatory. If you make an inferior play, the game will warn you first. I recommend that before you play for real money both online in person that you practice on the game until you very rarely are warned you a making an inferior play. If doubling or splitting is mathematically the correct play, but you don't have enough chips, the game will give the best advice for what you can afford to do. Do not change rules mid-hand. If you do, the change will not take effect until the next hand. The advice is based on my own analysis and basic strategy tables for one, two, and four+ decks. The deck(s) is(are) shuffled after every hand.

If you find any bugs, please contact me. A screenshot would be appreciated if you claim the game is misplaying a hand. I get a lot of incorrect reports that the advice given is incorrect. This usually can be explained by the user not using the correct basic strategy for the rules selected. I have also had many comments about the advice on a player 16, composed of 3 or more cards, against a 10. As a rule of thumb, the player should stand in that situation. However, that is a basic strategy exception. The game only knows basic strategy. Also, please note that it is a standard blackjack rule that split aces get one card each. If one of them is a ten, it is not a blackjack, it is just 21 points. That is how blackjack is usually played.

Blackjack Online FAQ

Q1: What are the rules in online blackjack games?

A: As in land casinos, they vary. Online help files are notoriously badly written and incomplete. The Wizard of Odds, we try hard to keep an accurate listing of rules for every brand of software and live dealers. You may find such rules, for every game, in our Software Review section.

Q2: Generally speaking, are the rules better in land or online casinos?

A: All things considered, I would say they are better online. For one thing, you almost never see a blackjack (ace and 10) pay 6 to 5 only online, while this is becoming the norm in land casinos in the United States.

Q3: What are the typical rules at live dealer casinos online?

A: Live dealer rules are very similar to what you would see in a land casino. The typical rules are:

Free Casino Games Blackjack 21

  • Eight decks
  • Dealer stands on soft 17
  • Dealer does NOT peek for blackjack
  • No surrender
  • Player may double on any two cards
  • Player may double after a split
  • No re-splitting

Be careful double or splitting if the dealer has a ten or ace showing. At most live dealer brands, you will lose everything if the dealer gets a blackjack. Under this 'no peek' rule, the only time you should put more money out on the table against a potential dealer blackjack is to split two aces against a dealer 10.

The house edge under the rules above is 0.61%.

Q4: When are the cards shuffled in online blackjack?

A: In a fully electronic game, they are probably shuffled after every hand. In a live dealer game, they are usually shuffled about half way through the shoe.

Q5: Oh really?! Even with only 50% penetration, what is to prevent me from counting cards against a live dealer?

A: I've asked this question of some people in the business. Nobody would tell me exactly how they protect their game against counters, but they assured me that they do. If I ran a live dealer casino, I would run a test of every player to see how their bet size is correlated to the true count. Then I would carefully examine the play of such players with a strong correlation.

Q6: How do 'probably fair' casinos accomplish so-called in blackjack?

A: It is rather involved, but here is typically how it is done:

  1. The casino will generate a random long string of characters, called a Server Seed, hash it, and give the hashed result to the player BEFORE he makes a bet.
  2. The player chooses a string of characters himself, called the Client Seed, or accepts a random default provided by the casino.
  3. The client and server seed are combined and hashed.
  4. The hashed result from step 3 will be parsed somehow, with the hexadecimal characters converted to base 10 and then mapped to specific cards if in a desired range.
  5. The game will deal cards according to their order in the hash from step 3. This hash should be long enough that running out of cards would be almost impossible.
  6. After the hand, the casino should reveal the Client Seed, which the player may verify hashes to the result provided before the bet. It is then a tedious process above to do all the math to convert the hash to actual cards, but the player may do that if he wishes.

I go into this in greater depth for a particular brand in my page on Blackjack (Encrypted Version).

Q7: I don't want to bother jumping through all those hoops to verify fairness in an encrypted game. Do you think that just the ability to verify fairness is enough to keep the casinos honest?

Blackjack

A: No. Encrypted or not, a casino could cheat the player in any game, except sports betting, any time they wished. In the case of an encrypted casino, the operator could choose a Server Seed that causes the player to lose after the bet is made. If the player catches them in a hash mismatch, which I think very few players bother to check, the casino can simply ignore the accusation or deny it without comment. This is exactly what happened to me at Wixiplay.

Q8: Your story aside, how common is cheating at blackjack, or any game, online?

A: In my opinion, it is quite rare.

Q9: How can I improve my odds of not being cheated?

A: There are hundreds, perhaps thousands, of Internet casinos out there. In the absence of any serious government regulation, the industry has done a pretty good job of regulating itself. Between legitimate watchdog affiliate sites and some common sense, here are some ways to choose a reputable brand to trust with your hard-earned dollar:

  • Read the fine print. Most casinos have a good looking main page, but dig around the more obscure pages like terms & conditions. If you see a lot of spelling and grammatical mistakes, that should set off a red flag.
  • Ping customer support. If you can't think of your own question, ask anything, for example, 'Do you accept players from Kyrgyzstan?' See how long it takes for them to reply and measure their professionalism and courtesy of their reply.
  • Check reputable affiliate sites. Many affiliate sites promote whoever pays the most, but the good ones are picky about who they promote and will intervene in the unlikely event of a player dispute. We would like to think of ourselves as one of the good ones. A good way to avoid the worst of casinos is to check the blacklists of reputable affiliates.
  • Smart small. Players should always bet in moderation anywhere, but especially when opening a new account online with an unfamiliar brand. Dink around with a small deposit and small bets until you have built up some trust.

Q10: Any other words of advice before playing blackjack online?

Play free blackjack against computer

A: Whether playing online or in a land casino, use the appropriate basic strategy for the rules offered. The Wizard of Odds blackjack strategy calculator will give the correct basic strategy for almost any set of rules.
A much greater problem than outright cheating is online casinos faulting players on a technicality in the rules and seizing whatever funds they deem appropriate. This is a particularly a problem with bonuses. The terms and conditions for bonuses can be pages long and very restrictive in terms of allowed games, bet sizes, and types of bets. If the player loses, nobody ever checks, but after a win and withdrawal request, suddenly the play may be subject to careful review for compliance. Never assume that because you were invited to play a bonus via Email that you're eligible for it. Casinos typically blast everybody in their list. An easy rule to overlook is when a bonus is eligible for 'new money' only. Don't expect the casino to enforce this rule when entering a couple code, but do expect it when you actually make a withdrawal and they look for any reason to deny it.
While bonuses can make your money last much longer and increase your chances of winning, they are a minefield in terms of compliance. Read the rules carefully. If in doubt the way you play is compliant, then don't ask for the bonus in the first place.
