Is online blackjack rigged or fair?
Thanks for the compliments. Other casinos have promotions in which the player who plays the most hands in a period of time wins a prize, in which a robot player would have a clear advantage. Skip your chance to take another card. This works to the player's disadvantage because more cards will be dealt when the shuffle point is reached in a deck rich in small cards than one rich in big cards. The 3rd column has, I believe, 8 reds and only 4 blacks.
The Origins of Blackjack
Unified Gaming had a blackjack game with an 0. Many Real Time Gaming casinos offer a joker poker game with an expected return of Other casinos have promotions in which the player who plays the most hands in a period of time wins a prize, in which a robot player would have a clear advantage. About your second question the bell curve is a forward looking estimate of the sum of many random variables.
You can not mix together past and future events. Once an event has happened it is no longer a random variable but a cold hard outcome.
Starting from hand your results could fall anywhere on a new bell curve. I hope this helps, but it really takes a course in statistics to truly understand. What is the best blackjack program to purchase for my pc. I want to learn to play BJ but since I am a beginner the tables are too intimidating.
I would download some Internet casino software and just play in free mode. However to learn proper basic strategy I would recommend making flash cards with every possible play. Dealing out cards at random will not test you often enough on the soft doubles and splits. I just wanted to make sure that the correct play in the Microgaming single deck game of A,A vs A is to split as shown on your basic strategy card.
Any chance you have the EV of hitting vs splitting on this hand? Based on one deck the expected value of each hand considering the possibility of a dealer blackjack is Splitting is also better for the 4-deck game, which no Microgaming player should be playing since a 1-deck game with the same rules is available.
Why do land casinos make you bet more when playing a second hand in blackjack? When playing on line is there an advantage when playing two or more hands? This will slow down the game and possibly prevent bigger bettors from playing. Not all land casinos have this rule, I think it is more prevalent in Atlantic City, where tables are more crowded, than Las Vegas. Whether online or a land casino there is no advantage to playing more than one hand. I have down loaded many black jack games from internet both stand alone and on-line.
Had played for long time and felt the games are different in difficulty to win especially the slot, pardon me if I am wrong. If it is true than is there any way to find out if the online games are truly random or any trusted organization we can get truly depend on?
It is a good sign if a casino has an independent auditor to review the log files for fairness and randomness. I used to provide such a service to online casinos myself. I have a question regarding the Microgaming no hole card rule for single deck BJ game. I remember reading in some forum that you concluded there is no difference to the HA whether the hole card is dealt or not at the beginning of the game.
I do notice that Microgaming has a higher chance of blackjack. Taking as an extreme example: Please let me know what you think. An unseen card is an unseen card, much in the same way the effect is the same whether the dealer burns a card or deals one less card out of the shoe. I hope this answers your question. Is there software that will count cards as you input them?
Can this be used to play online blackjack? Or does online blackjack shuffle after each hand? Have a look at Beejack. Most, but not all, casinos shuffle after every hand. I don't know if it practical to actually use this product. If you try it please let me know how you do, I might like to try it myself. The link to Beejack was removed in , due to a potential virus with that site.
Proceed there with caution. I read about someone winning 1. What is robot play, how does it win, and why is it illegal? First, the game was Caribbean 21, not Caribbean Stud. The casino this money was won from alleges that the player used robot play, which is against their terms and conditions.
If this is true the player denies it then it is within their rights to forfeit the winnings. Robot play is a program that can read the cards on the screen and can play against the casino by itself, by simulated mouse moves and clicks, or keyboard actions.
Robot play could ensure nice expected hourly profits for the person using it, but not enough to bother actually playing. Some casinos with no positive expectation game allow robot play and others do not.
I do not know why those with no positive expectation games prohibit robot play. Some skeptics claim they retain the right to avoid paying big winners, simply by alleging robot play.
In this situation the casino has released a taped confession in which the player offers to sell the robot. However the player says it was taken out of context.
Are there any basic strategy exceptions for doubling and splitting on the Internet when cash back applies to the total amount bet thus giving the player an extra incentive to double or split. Please assume a cash back rate of 0. I could not find any hand where an extra 0. The closest case I could find, based on six decks and the dealer standing on soft 17, is A,4 against a dealer 4.
In that hand doubling costs the player just under 0. So if you can get 0. I was at the Luxor this week and I noticed a blackjack machine that looked much like a video poker machine. Do these things use random generators like online, or do they work like slot machines? Online blackjack, slot machines, and video blackjack all use random number generators.
It is a Nevada state law that an electronic game with representations of cards or dice must be based on fair odds. So the game should be fair with odds the same as in a hand dealt game having the same rules. I noticed that all video blackjack games that I've played in Vegas pay even money on a blackjack. Is this fair according to the rules of blackjack? Because in a previous question July 4, you said, "It is a Nevada state law that an electronic game with representations of cards or dice must be based on fair odds.
What I meant was that images of cards on the screen had to be statistically fair. For example if you took a tally of each card observed in the initial hand of video poker or video blackjack you would see the distribution approaching a flat line over time, much as you would in a hand dealt game. However there is no law that the standard rules of blackjack must be followed.
The machine can legally offer horrible rules like the player losing on ties. Hi, I found a Double Exposure game where the ties push. The full rules are: Dealer hits soft All ties push, except player wins tied blackjack. Player can double on hard 9 to 11 only. Player can re-split, including unlike tens, to four hands. Double after split allowed.
Draw to split aces allowed. This must have a player advantage, can you tell me what it is? As I'm sure you know this game is offered by Lucky Chance casino.
Using the appropriate basic strategy for these rules the player advantage is 7. Wait it gets even better. The probability of getting three blackjacks in three hands is 1 in So I simply exited after every hand, except on a push.
However I'm suspicious if the player advantage is too high. That is two red flags. It was my goal to either make a fortune on their Double Exposure game or prove the game was not fair. Following are my results:. The probability of only winning 3 or less is This is using a standard deviation of 1. My source of the 1. This certainly does not rise anywhere near enough to make any accusations. In addition I recorded results all sorts of ways but every test came out looking normal.
I would have played longer but the game play is extremely slow and I went broke. The reason I went broke is I did worse on larger bet sizes and my first few hours I didn't record results but they were not good. So I failed on both my goals. I was too skeptical to deposit again and already wasted several hours on the game. However, if you wish to take a crack at it then be my guest.
How would it change the strategy assuming Cryptologic rules 6 decks and how does it increase the house edge? Not being allowed to split aces increases the house edge by 0.
You should only double against a six, otherwise hit. In Boss Media single-deck blackjack the player has the edge? So I could go to one of the online casinos and play it using optimal strategy AND win over the long run? What am I missing? However if you are going to play anyway you may as well get the best odds possible.
Thank your for your informative column. I have been using the "Fun" mode to practice the basic blackjack strategy online Golden Palace and Grand Online Casino.
I generally do well on the fun mode, but when I go to " Real Money " mode I start losing quickly using the same strategy. Do the online casinos change the software randomness for "Fun" mode letting us win, only to entice us to deposit real money. I know the Elka casinos used to do this for which I blacklisted them , but fortunately they seem to have vanished. If anyone can show me hard evidence that a casino is intentionally allowing players to win in fun mode I would be happy to investigate it.
Hard evidence means, at a bare minimum, a record of hands won and lost in each mode, for several dozen hands. Simply telling me that you lost "a lot more" when in real mode is useless.
Dear Wizard, I have read your comments about online blackjack and the fact that the decks are shuffled after each hand. Is there a casino online that has less shuffling or if not, am I forced to play live dealer blackjack which has more decks stacked and at least I can be aware of when shuffling does occur. Perhaps you misunderstood the point I was trying to make in my blackjack appendix The bottom line is that unless you are a card counter shuffling after every hand, as opposed to using a cut card, is a good thing.
The house edge is reduced 0. Hi wiz, as always, thanks for the great site and love your columns and especially the relationships questions. I have a question about my online blackjack play. I have been playing for quite a while and keep a record or my results. For such a reasonable sized sample, that seems to be a fairly large discrepancy. Are there any reasons to be suspicious based on these results? Thanks and all the best. Thanks for the kind words. According to my blackjack appendix 4 the standard deviation per hand, playing two hands at a time, is 1.
So the standard deviation of , such hands would be , 0. The probability of doing this badly or worse can be found in Excel as normsdist I lost a lot of money playing Cryptologic Blackjack today. Within 35 hands, the dealer showed a 6 seven times and won each time.
This was verified through the logs. At Cryptologic they use 8 decks and the dealer stands on a soft According to my blackjack appendix 2 , the probability of the dealer busting with a 6 up is 0. So the probability of not busing is 1 - 0.
The probability of not busing 7 times out of 7 is 0. When I have no 2s in my hand but an inside straight possibility you say to hold the inside straight chance.
So I was wondering, should play be modified a bit when playing hands at once? Or is it actually something with the pay table that causes that one play not to be quite right? To answer your question, the strategy depends only on the pay table.
The number of hands makes no difference. What is right for one hand is right for hands. On average you should get about 34 coins back playing the inside straight and 32 coins back tossing everything.
However, actual results will vary. Could You please make a chart for Party Poker single deck blackjack. Also, with best play, what are the odds. As I read them, the rules are: At BetJamaica I played 30 hands and lost What is the probability of that? The standard deviation per hand in blackjack is 1.
Your losses exceeded expectations by The probability of that is 0. If you still suspect something fishy, I would gather a larger sample size. Is it just me or does the sound of offering "live blackjack" on online casinos just BEG for card counting? I agree, that does seem like a good advantage play. At the 5dimes live casino game they offer the following rules:. One burn card at the beginning of the shoe, and one with every dealer change, which occur every 30 minutes.
Dealer stands on soft Early surrender, except against an ace. Split to two hands only. No hole card, but player loses original bet only to dealer blackjack. Shortow, a member of my forum, placed two videos of the cut card placement on YouTube: Video 1 Video 2. It looks to me like the penetration was a little deeper in video 2.
Not only could the player easily count this game, but he could use a calculator on a separate screen to make perfect decisions. The Blackjack Real Time Analzyer is one product that does this. However, I have no idea what kind of game protection they employ. With every card scanned, it would not be difficult to determine the correlation between count and bet size and raise a red flag if the correlation was sufficiently positive.

It is also common for these tests to be done randomly especially when made by a separate third party group. For online blackjack, it is the Random Number Generator or RNG that goes through the process of being tested and then recertified from time to time.
It is also important to note that reputation is basically the all-important factor for the continued operation of an online casino. An established Internet casino would not want to risk its reputation by rigging their own games.
On the contrary, online casinos want steady profits and a steady progress in volume of operations which can only be achieved by having and maintaining a good reputation online. In the online casino business, legitimacy and reliability go hand in hand. These are the two most important features to build trust. This is also the surest way to build a collection of steady and long-term customers. However, even with all the strict regulations put on casinos, there are still some people who are convinced that they online blackjack is rigged.
Specially when they do not win at blackjack. It could be possible if you are playing in a disreputable casino. Or it is also likely that you do not understand the basics of the RNG of blackjack. Legitimate casinos would definitely steer clear from any form of cheating as this would result in the long term in lesser revenues for the online casino being classified as rogue by the online community.
On the other hand, to provide a safe and secure place to gamble will surely gain them more customers and therefore more profit, as compared to rigging the results of their blackjack games. There are two black jack cards, spades and clubs. In card room circles or home games, the jack of spades is nicknamed Ogier.
