- The name ‘blackjack’ initially came about when French colonists introduced the game to US gambling houses in the 1800s. Players were offered bonus payouts for a hand with an ace of spades and a blackjack (either jack of clubs or jack of spades). As the game became more popular in the US, the name stuck.

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.
I would like to thank JB for his outstanding work on this game, and Dingo Systems for the cards.

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:
- 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:
Are Blackjack Odds Better With More Players
- 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.
- The player chooses a string of characters himself, called the Client Seed, or accepts a random default provided by the casino.
- The client and server seed are combined and hashed.
- 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.
- 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.
- 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?
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.
Which Blackjack Has The Best Odds
50 free spins no deposit required usa. Q10: Any other words of advice before playing blackjack online?
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.

Blackjack odds are percentage figures which represent your probability of losing or winning a hand. They can also represent the house edge or their profit margins as well. Usually probability odds don't mean much on the short term, but they clearly average out in the long term and this is why the casinos always win over the long term.
We decided to make a few tables and charts of the most common blackjack probability odds for various scenarios and situations found while playing blackjack. The most important odds percentage represents the dealer's edge in the game. This is the long term advantage that they have which will eventually take your money away. Blackjack is actually one of the most popular games in the casino and also has some of the lowest odds of all the casino games, except casino craps of course. Generally their edge ranges from 1% to 15% depending on what variation of blackjack you are playing.
How to Beat the Casino House Odds
There is one feature that makes blackjack more desirable than any other casino game. There is actually a way to beat the house edge by increasing your odds. In fact, your probability odds in blackjack can be increase to the point where you would actually be making the profit in the long term, essentially turning the casino into a personal ATM. This practice is known as card counting and casinos don't like this because they know they will be losing money.
Before you start card counting, you should learn 'blackjack basic strategy', which is the mathematically correct way to play every move in blackjack to get the best odds. This can lower the house edge to less than 1 percent. When that percentage goes to a negative number such as -1%, then it is you who has the edge over the casino. This is when you complement basic strategy with card counting to get the highest efficiencies.
Odds vs. Dealer Up Card
The first odds chart shows what kind of advantage the player has vs. the dealer based on what his up card is showing. The first column in the chart is what card the dealer has showing after the cards have been dealt. The second column of the table shows the dealer's probability of going bust based on each card. The last column shows the advantage the player has and the probability of winning based on the basic strategy theory. As you can see, the dealer has about a 43% chance of going bust when he has a 5 showing as an up card. At the same time, the player has about 23% advantage as well. Notice that the player advantage goes negative when the 10 cards and ace start showing up. This means the player is more likely to lose.
|Dealer's Up Card||Dealer Odds of Busting||Player Advantage Percentage|
Blackjack odds of Busting While Taking a Hit
This chart shows the probabilities of going bust after taking a hit. Busting means that your card total would go over 21 points and would be a hard total as well. The highest score you can get when being initially dealt two cards is 21 points so you can never go bust. This means if you took a hit on a hard 21, you would have a 100% probablity of going bust, which is common sense. Also, if you have 11 points or less, it is impossible to go over 21 points on the next hit and your odds of going bust would be 0 percent.
|Total Hand Value||Probability of Going Bust|
|11 or less||0%|
House Advantage with Multiple Number of Decks
The number of 52 card decks in a game of blackjack influences the house edge. In some cases, the odds increase in favor of the casino when more decks are used. The advantage edge can be as much as 1% towards the casino and this is a big number in terms of odds over the long term. As you can see here, a single deck of card gives the lowest edge for the casino and gives the player better odds. Multiple decks such as eight decks increases the house edge almost 18 times more than it would for the single deck!
|Number of Decks||House Odds Advantage|
Two Card Frequency Odds
The next odds table deals with the first two cards being dealt or the 2 card frequency odds. Every player is dealt two cards at the beginning of a round of blackjack so this chart tells you the percentage of getting different categories of hands. A natural blackjack is only 4.8%, which essentially is an ace dealt with a ten card straight off the initial deal. Normally the odds are 3 to 2 and you would win $3 for every $2 wagered. It's a small percentage but it's the most desirable hand to get. The lowest hand you can get is two points (two aces). This is part of the decision hands group where players are usually dealt soft hands and can make decisions without going bust. This group is the most common.
The other category is the hard standing hands. These hands are somewhat desirable because of the high scores likely to beat the dealer. These are the second most frequent two card blackjack hands. Finally there is a no bust two card hand. No bust means any two card hand that won't bust on the next hit, such as any soft hand or hard hand that is 11 points or less.
|Two Card Combination||Frequency Percentage|
|Natural 21 Blackjack||4.8%|
|Hard Standing (17 - 20)||30.0%|
|Decision Hands (2-16)||38.7%|
|Total (all two card hands)||100%|
Probability Edge for Each Card Removed from Deck
The next table shows how much your odds improve after when certain cards have been dealt and removed from the deck. Certain cards taken out of the deck and increase or decrease your blackjack odds percentage and the house edge.
This is very important for card counting. If you want the absolute perfect odds in card counting, you have to acount for each small change in the odds whenever a card is dealt. As you can see from the table, when small cards are taken out of play, the odds increase in your favor overall. This is a paramount property of card counting. The opposite happens when large cards are dealt. Your odds begin to decrease. When you are counting cards, you will notice your count decreasing when large cards are dealt.
You can imagine how complicated it would be to be adding these numbers in your head while card counting at the same time. If your mind was a computer, it would be easier to keep track of the percentage. Some people can do this, and this is the way to become a perfect card counter! It is easier to keep track of the odds when playing with a single blackjack deck. For example, when five cards are seen on the table, they offer a 0.67% increase in your advantage. In fact, when a lot of fives are used up, your odds will be much higher than if any of the other low cards were used up, even the six point cards. Also, these effects are cumulative so you always need to keep track of the odds after every card is dealt. This data is actually quite amazing!
|Removed Card||Effect on Odds|
Dealer Final Hand Probability Odds
This next table shows the odds of what the dealer's final hand will be. Usually in blackjack, the dealer must hit on 16 and stand on 17. These rules are slightly different for other variations of twenty-one. So generally, the odds of the dealer's final score being 16 are 0% because he must hit. This table will show the probability of the dealer busting or getting a non-bust hand as well as natural blackjacks.
|Dealer Final Hand||Probability of Getting Final Hand|
|21 (more than 2 cards)||7.36%|
|Non-Bust (less than 21)||71.63%|
|Bust (more than 21)||28.37%|
