Yes, tipping the dealer is common. Explanation of what the objective of blackjack is, and what the player has to do in order to win money are also important concepts. If you accept, the dealer will pay you the amount of your original bet and discard your hand of blackjack, before he even checks under his Ace to see if he has a blackjack as well. So, the answer to that question is always no. Unless you are card counter and know the deck is skewed sufficiently, just ignore the insurance bet. This is the home of anything and everything players will need and want to know about online blackjack, including the great free play versions of blackjack.
Part 1 – Blackjack Basics
If the strategy says to surrender 16 vs. If the strategy says to "not split," then treat the hand has a hard total of 8, 10, or 20, according to the pair in question. A reader named Jeff provided another table of my simple strategy, with exceptions in small print. Details about the Wizard's Simple Strategy can be found in my Blackjack appendix See my Blackjack House Edge Calculator to determine the house edge under 6, possible rule combinations.
Following is a list of some common rule variations and the effect on the player's expected return compared to standard U. Rule Variations Rule Effect Single deck 0. Beware Short Pays on a Blackjack More and more tables are showing up that pay less than the full 3 to 2 on a blackjack. Most of these tables pay 6 to 5, but some even money and 7 to 5 tables are known to exist.
In my opinion, only games that pay 3 to 2 deserve to be called "blackjack," the rest fall under "21" games, including Super Fun 21 and Spanish Regardless of the other rules, you should demand nothing less than 3 to 2 blackjack. You should always check the felt to be sure, and if the felt doesn't say, look for a sign. If nothing says the win on a blackjack, then ask. Three popular bad strategies encountered at the blackjack table are: All three are very bad strategies. Following are my specific comments on each of them, including the house edge under Atlantic City rules dealer stands on soft 17, split up to 4 hands, double after split, double any two cards of 0.
For my analysis of this strategy I assumed the player would never hit a hard 12 or more. All other decisions were according to correct basic strategy. This "never bust" strategy results in a house edge of 3. For my analysis of this strategy I assumed the player would always hit 16 or less and stand on17 or more, including a soft The player never doubled or split, since the dealer is not allowed to do so.
This "mimic the dealer" strategy results in a house edge of 5. Assume a ten in the hole: For this strategy I first figured out the optimal basic strategy under this assumption. If the dealer had an ace up, then I reverted to proper basic strategy, because the dealer would have peeked for blackjack, making a 10 impossible.

Total dependent expected return table for an infinite deck 2a: Probabilities of dealer blackjack after peek 2b: Probabilities of dealer blackjack before peek 3a: Exceptions to single-deck S17 basic strategy 3b: Exceptions to double-deck S17 basic strategy 3c: Exceptions to single-deck H17 basic strategy 4: Blackjack standard deviation details 5: With no hole card, it is almost never correct basic strategy to double or split against a dealer ten or ace, since a dealer blackjack will result in the loss of the split and double bets; the only exception is with a pair of A's against a dealer 10, where it is still correct to split.
In all other cases, a stand, hit or surrender is called for. For instance, holding 11 against a dealer 10, the correct strategy is to double in a hole card game where the player knows the dealer's second card is not an ace , but to hit in a no hole card game. The no hole card rule adds approximately 0. The "original bets only" rule variation appearing in certain no hole card games states that if the player's hand loses to a dealer blackjack, only the mandatory initial bet "original" is forfeited, and all optional bets, meaning doubles and splits, are pushed.
Each blackjack game has a basic strategy , which is playing a hand of any total value against any dealer's up-card, which loses the least money to the house in the long term.
An example of basic strategy is shown in the table below, and includes the following parameters: The bulk of basic strategy is common to all blackjack games, with most rule variations calling for changes in only a few situations. For example, if the above game used the hit on soft 17 rule, common in Las Vegas Strip casinos, only 6 cells of the table would need to be changed: A, surrender 15 or 17 vs. A, double on A,7 vs. Also when playing basic strategy never take insurance or "even money.
Estimates of the house edge for blackjack games quoted by casinos and gaming regulators are generally based on the assumption that the players follow basic strategy and do not systematically change their bet size.
Most blackjack games have a house edge of between 0. Casino promotions such as complimentary matchplay vouchers or 2: Basic strategy is based upon a player's point total and the dealer's visible card. Players may be able to improve on this decision by considering the precise composition of their hand, not just the point total.
For example, players should ordinarily stand when holding 12 against a dealer 4. However, in a single deck game, players should hit if their 12 consists of a 10 and a 2. The presence of a 10 in the player's hand has two consequences: However, even when basic and composition-dependent strategy lead to different actions, the difference in expected reward is small, and it becomes even smaller with more decks.
Using a composition-dependent strategy rather than basic strategy in a single deck game reduces the house edge by 4 in 10,, which falls to 3 in , for a six-deck game. Blackjack has been a high-profile target for advantage players since the s.
Advantage play is the attempt to win more using skills such as memory, computation, and observation. These techniques, while generally legal, can be powerful enough to give the player a long-term edge in the game, making them an undesirable customer for the casino and potentially leading to ejection or blacklisting if they are detected. The main techniques of advantage play in blackjack are as follows:. During the course of a blackjack shoe, the dealer exposes the dealt cards. Careful accounting of the exposed cards allows a player to make inferences about the cards which remain to be dealt.
These inferences can be used in the following ways:. A card counting system assigns a point score to each rank of card e. When a card is exposed, a counter adds the score of that card to a running total, the 'count'.
A card counter uses this count to make betting and playing decisions according to a table which they have learned. The count starts at 0 for a freshly shuffled deck for "balanced" counting systems. Unbalanced counts are often started at a value which depends on the number of decks used in the game. Blackjack's house edge is usually between 0.
Card counting is most rewarding near the end of a complete shoe when as few as possible cards remain. Single-deck games are therefore particularly susceptible to card counting. As a result, casinos are more likely to insist that players do not reveal their cards to one another in single-deck games. In games with more decks of cards, casinos limit penetration by ending the shoe and reshuffling when one or more decks remain undealt. Casinos also sometimes use a shuffling machine to reintroduce the exhausted cards every time a deck has been played.
Card counting is legal and is not considered cheating as long as the counter isn't using an external device, : Sometimes a casino might ban a card counter from the property. The use of external devices to help counting cards is illegal in all US states that license blackjack card games. Techniques other than card counting can swing the advantage of casino blackjack toward the player.
All such techniques are based on the value of the cards to the player and the casino as originally conceived by Edward O. Shuffle tracking requires excellent eyesight and powers of visual estimation but is more difficult to detect since the player's actions are largely unrelated to the composition of the cards in the shoe.
Arnold Snyder's articles in Blackjack Forum magazine brought shuffle tracking to the general public. His book, The Shuffle Tracker's Cookbook, mathematically analyzed the player edge available from shuffle tracking based on the actual size of the tracked slug. Patterson also developed and published a shuffle-tracking method for tracking favorable clumps of cards and cutting them into play and tracking unfavorable clumps of cards and cutting them out of play.
The player can also gain an advantage by identifying cards from distinctive wear markings on their backs, or by hole carding observing during the dealing process the front of a card dealt face down. These methods are generally legal although their status in particular jurisdictions may vary. Many blackjack tables offer a side bet on various outcomes including: The side wager is typically placed in a designated area next to the box for the main wager.
A player wishing to wager on a side bet is usually required to place a wager on blackjack. Some games require that the blackjack wager should equal or exceed any side bet wager. A non-controlling player of a blackjack hand is usually permitted to place a side bet regardless of whether the controlling player does so.
The house edge for side bets is generally far higher than for the blackjack game itself. Nonetheless side bets can be susceptible to card counting. A side count, designed specifically for a particular side bet, can improve the player edge. Only a few side bets, like "Lucky Ladies", offer a sufficient win rate to justify the effort of advantage play. In team play it is common for team members to be dedicated toward counting only a sidebet using a specialized count.
Blackjack can be played in tournament form. Players start with an equal numbers of chips; the goal is to finish among the top chip-holders. Depending on the number of competitors, tournaments may be held over several rounds, with one or two players qualifying from each table after a set number of deals to meet the qualifiers from the other tables in the next round.
Another tournament format, Elimination Blackjack , drops the lowest-stacked player from the table at pre-determined points in the tournament. Good strategy for blackjack tournaments can differ from non-tournament strategy because of the added dimension of choosing the amount to be wagered. As in poker tournaments, players pay the casino an initial entry fee to participate in a tournament, and re-buys are sometimes permitted.
Some casinos, as well as general betting outlets, provide blackjack among a selection of casino-style games at electronic consoles. Video blackjack game rules are generally more favorable to the house; e.
Video and online blackjack games deal each coup from a fresh shoe, rendering card counting much less effective.
Blackjack is a member of a large family of traditional card games played recreationally all around the world. In these "European No Hole Card" games, the dealer only deals himself one card at the beginning of the round. After all the players have completed their hands, he deals his own second card and completes the hand. Contrast that with the normal US style of play. There, if the dealer has a ten or Ace card up, he checks the other card immediately to see if he has a blackjack.
If he does, the hand is over. This process of "peeking" under the hole card to check for blackjack means that players can only lose one bet per hand if the dealer has a blackjack. In a No-Hole-Card game, a player might split or double and have multiple bets at risk to a dealer blackjack, because the dealer cannot check ahead of time.
This changes the optimal strategy, and means that players should usually not split or double against a dealer ten or Ace upcard. An exception is splitting Aces against a dealer ten. Note that there are a few no-hole-card games where the rules specifically say that only one bet will be collected from a player if the dealer has a blackjack. In those games, although there is no hole card, you can play the game as if there were. That means you should play it as a Peek game, even though there's not really a peek!
It's all a bit confusing. When the No-Hole-Card rule is in use, and all bets are at risk to a dealer blackjack, it costs the player 0. Use the "No-Peek" option at our Strategy Engine. Ok this one's an extremely rare variation which I doubt you will see in any casinos today but I thought I'd mention. Similarly there is a rule variation whereby the player automatically wins when drawing 7 cards without busting which is called a "Seven Card Charlie". The most important item is the sign declaring betting limits.
Both the minimum and the maximum allowable bets should be on a sign on the table-top. Look around to find a table that suits your bet sizes. Make sure that the table you have selected is actually for blackjack, and not another of the many kinds of table games that casinos offer.
Look on the table for the phrase " Blackjack pays 3 to 2 ". Avoid any games that say " Blackjack pays 6 to 5 " instead. See 6 to 5 Blackjack? Beginners should start off playing the shoe games. The advantage in this style is that all of the players' cards are dealt face-up, so the dealer and other players can easily help you with playing questions and decisions.
Once you become proficient at the game, you may want to switch to a game with fewer decks since that lowers the casino's advantage. The dealer will exchange the entire amount of cash for the equivalent in chips, and drop the cash into a box on the table. Take a quick look at the chips to make sure you know the value of each color. If you have any questions, just ask the dealer.
Part of his job is to help players learn the game. Once you are ready to place a bet, wait for the current hand to be completed, then push your bet into the betting circle. Your chips should be in one stack. If you are betting multiple denominations of chips, place the larger valued chips on the bottom of the stack, and the smaller value chips on top.
Once the cards have been dealt, you are not allowed to touch the bet in the circle. If you need to know how much you have bet for doubling or splitting explained later , the dealer will count down the chips for you. Once the hand is over, the dealer will move around the table to each position in turn, paying winning hands and collecting the chips from losing hands.
After the dealer has paid you, you can remove your chips from the circle, and place your next bet. If you want to let your winnings ride, you will need to form one stack of chips from the two or more stacks on the table after the dealer pays you. Remember, higher value chips should be placed on the bottom of the stack. When you are ready to leave the table, you do not cash in your chips the same way you bought them. The dealer cannot give you cash for the chips at the table. To do that, you must take the chips to the casino cashier.
If you have a lot of low denomination chips in front of you at the table, you should trade them for the equivalent higher value chips instead. In between hands, just tell the dealer you want to "color up", and he will have you push your chips into the middle of the table. He will count them down, and give you a smaller stack of chips that amount to the same value.
This makes them easier to carry for you, and for the dealer it maintains his supply of smaller chips. Now you can take those chips to another table for more play, or head to the casino cashier where you can exchange them for cash. So, if you have made it this far, congratulations.
You should have a good idea of what to expect when you sit down at a blackjack table in the casino. What we have not talked about is how to actually make the best decisions while playing the game.
That is a whole subject all its own. To have the best chance of winning, you should learn and practice "basic strategy", which is the mathematically best way to play each hand against each possible dealer upcard.

The original version of this explanation of the rules of blackjack has a very long history here at BlackjackInfo. I created and published it here sometime in It was widely copied by other sites, and it has appeared without my permission on literally hundreds of sites over the years.
When I relaunched BlackjackInfo with a new mobile-friendly design in , I took the opportunity to write this all-new version. Hmmm seems I have been making some bad calls for years now, I thought splitting tens against anything but an ace or 10 was a good move: If a player decides to stand on 15 for whatever reason and the dealer has 16, must the dealer still draw another card since it is less than 17?
Is there any significance in blackjack when you have a black jack paired with a black ace, same suit? The question came up on the multiple choice question on Millionaire. I guessed 16 but the answer was 32??? In playing 21 with one deck off cards aND two people playing, in playing Blackjack with one deck of cards and two people playing what is the most black jack show up.
Ken, This may not be the most appropriate page to post this, but let me explain the situation. I aspire to hopefully gather a group of trustworthy guys together to form a blackjack team. Team play is complicated and far more involved than a group of friends pooling resources.
There is not much published on team play. The following book may be helpful. The strategy does not change, but the player is worse off by around 0. As the dealer I get up to Can the dealer chose to stay and take the chips bet from player on the left.
But pay the player on the right? His rules are fixed. He must hit until he has 17 or higher, and then he must stand. Even if all the players at the table have 18, the dealer must stand if he ends up with a Most casinos now deal games with an extra rule about soft This is covered in detail in the article above. I have a question. I signed up on an online casino and I was getting ready to play blackjack for real money and I asked the live chat help person how many decks were being used and she said 24 decks.
Casinos, both online and land-based, can deal the game pretty much any way they like, including increasing the number of decks to a ridiculous 24! Fortunately, once you get to 8 decks, the game does not get much worse for the player by adding even more decks. Eight decks is the most typically seen in brick-and-mortar casinos, but in most jurisdictions, land-based or online, there is no legal requirement for any specific number of decks.
Is there any standard in the way a dealer deals from the deck? You are describing a CSM continuous shuffle machine , where after each hand the dealer immediately puts the used cards back into the shuffler. As you note, this eliminates the ability to count cards, or to even observe a useful bias.
Since used cards can return into play immediately, the penetration is effectively zero. These machines have spread widely. The only recourse is to see if your casino also still offers regular games either hand-shuffled, or machine-shuffled but with a normal discard tray. If not, voice your discontent and look elsewhere. Should I be able to ask a casino to provide a copy of their rules?
I assume you are talking about online casinos. I didnt catch it at first but sure enough when I drew another card I busted. This particular game would not count both my Aces as one. Is this ever done at a casino? Who knows what else they are doing wrong! To answer your question, no, this is never done at any casino I have visited. Is this a good bet?
What is the house percentage? Yes, there are outstanding opportunities afforded by some sidebets under some circumstances, but if you are able to figure out how to beat them, you no longer need to ask about them. So, the answer to that question is always no. I read the following in the Casino Verite Software: Can you help me with this? There you can find: This works because of the unbalanced nature of the count. Or do I need to count them equally? Treat them independently, and reassess after each drawn card changes the hand.
Here are some examples: You will draw each of those hands about once every hands or so. As to whether or not to double, 9,3 is a hard 12 and should certainly never be doubled. Also against a dealer 4 in some 1 and 2 deck games.
See the Strategy Engine for accurate advice for any game. I assume you are asking about accessing the charts on your smartphone in the casino.
I do not recommend that. In the US, there are laws prohibiting the use of devices in gambling. Most of these laws are based on the Nevada version, which is written in a way that it could be interpreted to mean even something as harmless as looking up a strategy.
If you want access to the strategy in the casino, get a plastic card instead. The shoe game will be easier for a visually impaired player, because both the other players and the dealer have full access to the needed information about the hands.
I have played at the table on many occasions with blind players, and the dealer has always assisted by verbally providing the details of the hand. Awesome page, One question.. Is this a standard rule?
Need to be sure which is the standard and which is the exception… Thanks. I have seen the behavior you describe in online casinos, but I have never seen it dealt that way in any land-based casino. There, the dealer always deals a card to the first split hand, finishes that hand, and then deals a card to the second split hand and begins it.
I was in Cancun in a casino and in one hand I had 2 Aces against dealer King. I split the 2 Aces and I,ve got Queens on both aces but the dealer draw a card that was an Ace and said that he won since he had blackjack and I only had Blackjack is 21 in the first two cards, and it beats a total of 21, even the case of splitting and getting two hands that look like blackjack. They are just 21s. But when the dealer does not take a hole card and all bets are subject to losing to a potential dealer blackjack , you should not double or split against a dealer ten or ace because of this.
Hi, can please anyone help me with an answer. Do casinos now change the deck of cards after every game or not? Because I heard lot of people saying that now it is impossible to memorise cards that are still in the game.
