Blackjack - Casinos using shuffle machines to cheat...?
I have down loaded many black jack games from internet both stand alone and on-line. There are some casinos that play into a shoe a little way but not far, and have restrictive betting limits. Since learning of this technique, that is also how I shuffle in my random simulation programs. Any chance you have the EV of hitting vs splitting on this hand? Jay from USA Both games are both shuffled after every hand. What do I need to have in order to play online blackjack?

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: There are numerous ways an online casino might cheat, but a bad shuffle I don't think is one of them. I was wondering if you thought continuous shufflers have an effect on basic strategy? I know they speed up the number of hands per hour which is usually bad for the player, but is basic strategy still effective in this instance?
Doesn't basic strategy slightly change depending on the number of decks? I first addressed this topic in my December 1, , newsletter. For those who missed it I just added blackjack appendix 10 to my site, which explains the effect on the house edge under both a cut card and continuous shuffler game. To answer your question, no, the basic strategy does not change.
Basic strategy is always developed based on a freshly shuffled shoe, which is always the case when playing against a continuous shuffler. There are a few cards left in the shoe part of the machine anywhere from 1 to 20 or so that are not shuffled.
Is there any way this can be used to advantage? For example, I was thinking that there is a lower but still not zero probability of having a card repeated two hands in a row. Sit out if there were a lot of high cards last hand. Maybe enough to skew the odds? As a card counter it would probably be safe to use a true count from just the last hand played and off the top of a shoe. On a CSM blackjack game, 5 deck, what would be the effect of the dealer not putting discards back into the machine every hand if 24 of 52 cards in the discard rack were face cards?
What about 48 of ? What would be the effect if 44 of 52 cards were non-face cards? Can the odds be heavily skewed? However your speculation is right that the odds favor the dealer if he leaves a lot of high cards in the discard rack yet will put back into play a lot of small cards. This would be the same kind of thing as preferential shuffling, in which the dealer of a hand held game shuffles when the count is good but deals another round on a bad count.
Preferential shuffling is something that definitely does happen here in Las Vegas so what you describe would not surprise me either. I was just wondering if Las Vegas Video Blackjack reshuffles after every hand or after all the decks are played.
I know the tables in Las Vegas do it after all the decks are played because if they did it after every hand no one would play. Is this even legal or necessary? First, thank you for the great site. I went to Las Vegas for this first time this past summer and I played double-deck blackjack at the Orleans. I noticed that after a dealer shuffled both decks, the dealer asked the player to cut the deck.
I did not mind, so I cut the deck. Is there a blackjack cut superstition that I am not aware of, or is there a better reason why? However if everyone initially declines somebody has to rise to the occasion and do it.
Of course this is nonsense. Playing blackjack on a continuous shuffling 5-deck system, are the odds of winning different than playing the dealer with 1 deck or 2 decks? For the beneit of other readers, my blackjack appendix 10 explains, the house edge in a five-deck game is 0.
