Here’s an example to show just how profitable online blackjack is with a fair game. If the average live dealer table has five players each betting an average of $25 per hand and the game deals 50 hands per hour the total amount wagered on the table per hour is $6,250. Provably fair blackjack games are not offered at many online casinos yet, but the number of casinos spreading these games is growing. Hopefully, in the future, provably fair games of all kinds will become the standard rather than the exception in online gambling.

I have been playing blackjack online at Bovada since the Bodog days (in the US). Being a software architect and developer for 20+ years I definitely have an intersecting interest in the game of blackjack and the coding that goes behind it. These games are supposedly certified by Gaming Associates using a pRNG, and Bovada will tell you it is completely fair using a normal sample size of 10,000+ hands. I have been accumulating my hand history for about a year and have close to 100,000 hands to evaluate. I can tell you while the hand %'s are on the money 44%win, 8%push, 48%loss, there are other statistics such as streaks, dealer dealt cards vs player dealt cards, drawing on 6 showing, and doubling that are certainly questionable. One most recent incident was a 485 hand session where I never won more than 1 hand in a row.
1. I know Wizard of Odds said he personally certified the Blackjack at Bodog/Bovada to be fair, but is that just a win/loss percentage check after x hands?
2. Is the outcome of the hand predetermined by the pRNG? Meaning, it wouldn't matter how the hand is played if action is taken without busting, the winner is already known.
Seems to me you could pass the pRNG test for hands won/loss, but adjust or force outcomes on premium double down hands to make the blackjack 'handicapped' over long term.
Also:
- Yes I know this has been beaten to death, but I feel like analytically I am digging a little deeper here.
- Yes I play in land based casinos all the time and I realize online you are seeing many times over the number of hands you could see live.
- Yes I know it is not to Bovada's advantage to offer a game that is 'rigged'. However, it is definitely to their advantage to ensure their system cannot be beaten.
- Yes I know its a continuous shuffle, and card counting doesn't apply.

Hi byte, and welcome to the forum. I'm in development (almost 10 years) as well (as other on here are). You seem to have fair points and questions, but what I can tell you now is it's going to come down to the data.
First, you'll need to post your data so that it can be analyzed and real numbers tests, such as what you're saying with the streaks/etc can be determined.
Next, your data will be questioned unless it's a video log of your screen while you play. People with grievances or whatever could/would fudge some of the numbers and possibly give bovada a scare, reputation hit, or whatever.
After getting a large, untamperable, sampling size then the real math can be worked on and proven/disproved. Until then I can agree with you all day but it won't actually account for much or mean anything unfortunately =/. You do seem like you have a fairly good idea of things too.

Hi, byte, and welcome to the forum. In the past, the Wizard has had to have hand logs to analyze, (which you have), and specific contentions to test against (which you kind of list; up to him the level of specificity he needs). He may answer your questions as to how the software works, or it may be proprietary to Bovada, I don't know. Seems like you might send him a Private Message (the envelope on the toolbar above) with a link to this thread (paste it in the message) asking him to take a look. He reads many things on here, but not everything, and I think he'd want to see this. (Please keep in mind, I don't speak for him; I just wanted to acknowledge your post.)Administrator
A couple of random thoughts. If the win/loss/tie percentage is right on expectation, I'm not sure how much interest there would be in the journey, as far as crunching the numbers/labor cost. However, there have been member requests before for large data files of hands from a consistent source, and it might be very much appreciated if you shared yours. Hold off on doing that for the moment, though; it's just a thought.
If the House lost every hand, they wouldn't deal the game.

One thing I thought would be interesting is what if they made the win/loss %'s correct, but as the OP said the streaks are horrific (in both directions) so that you have losing streaks you simply can't sustain. That would keep the %'s correct but still be a 'rigged' game.

Is the outcome of the hand predetermined by the pRNG?
No. What's random is how the cards are drawn. Depending on how it's programmed, either the entire virtual deck is shuffled randomly and then the cards are drawn off the top (which is CPU-intensive), or the cards are drawn randomly from an unshelled deck (which is much faster and simpler, and how I do it when I program simulations).

What is an 'unshelled deck'?

HeyMrDJ
What is an 'unshelled deck'?
I think he means un-shuffled, imagine 13 cards in order (obv theres more than 13 in a deck), if the RNG picks 8 it equals an 8, 13 = K and so on.
In my programming I shuffle the deck and draw off the top, in theory its the same thing, but I like to mimic real life as much as possible.
Guess who peed in my Cheerios? Romes did...

It occurs to me that if the overall medium term win/lose ratio is correct, but that they bias it towards player losing on high value hands, then wouldn't they have to counter balance that by rigging to pay out a larger proportion of hands where stakes are low? Wouldn't that give small scale betters an advantage.
Or do they do like VW and only un-rig it for audits.

Whomever thinks this RTG BJ software is 100% random I have a +EV betting situation for you. Because we will probably never get in enough big bets to prove anything a side bet will have to do. I don't believe counting the % of winning hands VS losing hands is a valid test, especially flat betting small amounts.
I always had a significant amount of disproportional big bets lose. For instance. Lets say I'm playing .50 VP then suddenly I decide to play a $100 hand of BJ. You guessed it, I have NEVER won a hand doing that.
When betting small $1-$5 It seems to play 'normal' of course you eventually lose. Anytime I have ever played bigger bets I go on the most horrible runs ever.
You use YOUR money to play.
You play a series of $1 bets, at some point I'll ask you to jump your bet to $100+.
I'll make you a side bet (my bet is that you will lose) and give you odds for an amount that puts you at a 1.5% advantage on each hand.
Anyone can quit wherever they wish.

You must be pretty convinced it's VERY gaffed to offer that wager. I'll pass.

It’s completely natural to be anxious before joining your first online casino. After all, you’ll have to make a real-money deposit on an online platform and trust it with your funds. If you are wondering whether online casinos are rigged, we’ll provide both a short and a long answer to that question. The short one is — no, they aren’t, as long as you stick to licensed and regulated ones.
If that does not convince you, make sure to read this article and find out more about different ways online casinos can be rigged and how to stay away from such platforms.
How Can an Online Casino Be Rigged?
There are many ways to rig an online casino. Simply put, all casino games you play online use sophisticated underlying software. Developers working for reputable online casinos and content providers make sure to write code so that it cannot be tampered with.
All it takes to rig an online casino game is to alter its code so that the game is not fair anymore. Rigged online casinos usually offer games that are identical to the ones in fair and licensed casinos — the only difference is that you don’t really have an opportunity to win any money. In other words, you’ll pay and not get anything in return.
The probability of winning a prize in a rigged casino is usually much lower due to low RTP percentages.
Lowering the RTP
RTP stands for Return to Player, and it’s a figure that shows how much money is returned to players when they make bets. If the RTP is 95%, players should receive $95 for every $100 they invest in online slots. Online casinos and developers will take the remaining $5 as a profit. Naturally, some players will be luckier than others and win bigger prizes, while the less fortunate ones will leave empty-handed.
Nevertheless, the overall distribution of prizes is such that casinos should take only a small portion of invested money while distributing the rest to players.
Rigged casinos often lower the RTP so much that it doesn’t pay off to play games. If the RTP is low, the casino will take most of the money you invest and your chances of winning a prize will be extremely low.
How do these casinos set the RTP? The answer is simple — they change the code and do not include the RNG.
RNG Doesn’t Work in Rigged Casinos
Every game of chance available in online casinos needs to have a random number generator (RNG). This is a piece of code included in casino games that ensures that they are truly random.
To explain the RNG further, we must first ask you the following question: How does luck work?
Nobody knows. It’s a complete mystery to us. The only legitimate answer is to say that luck is a product of the universe being random. Some people are luckier than others when playing casino games. You can look at the outcome of playing games of chance as one way to measure someone’s luck.
But how do you know that games are random? The answer is the RNG. Developers made a program that always comes up with entirely random results in games. Therefore, once they set the parameters and insert the RNG in the game, you can rest assured that there are no people on the other side adjusting the outcome — unless you’re playing in a rigged casino.
Games in rigged casinos aren’t random since they lack one of the essential pieces of software — the random number generator.
How Can I Make Sure That the Casino Is Trustworthy?
One of the safest ways to ensure that a casino is not rigged is to research the web and find additional information about the platform. Many professional reviews will tell you about all the disadvantages and disadvantages related to the platform you want to join.
Alternatively, you can find user opinions about specific sites and gather more info on their trustworthiness. Please note that users sometimes leave negative reviews about casinos and call them rigged simply because they weren’t lucky enough. However, if all user reviews agree that a certain casino is rigged, you should definitely think twice before you open an account.
The good thing about the online gambling industry is that rigged platforms have short lifespans. In other words, if someone proves that they are rigged, other players will find that information rather quickly. Such sites are usually then added to blacklists all over the web and players start to avoid them right away. Being busted, rigged online casinos then stop operating as they aren’t able to scam people anymore.

Yet, you should still be careful, as online scammers don’t give up easily. If their rigged platform is shut down, they often don’t hesitate to start the whole process afresh and lure newcomers into giving them their money.
Independent Auditors Ensure Fairness and Trustworthiness
If an online casino claims that it’s fair and trustworthy, why should you trust them? After all, they could lie about this and still proceed with illegal operations. That’s why independent auditing companies exist.
These are usually companies that are highly reputable as being independent and honest in their reports. They often check online casinos and other gambling platforms for fairness, after which they publish the results. To ensure that a casino is fair, auditors check their random number generators and many other things that help them determine whether a casino is fair and trustworthy.
Companies that are currently considered leaders in the online gambling industry are eCogra, GLI, and iTechLabs. If you find certificates from these auditing firms in an online casino, you don’t have to worry.

What Does an Online Licence Provide?
If an online casino lacks a licence provided by an official regulatory body, we advise you to stay away from it. It may not be rigged, but having no licence is not a good sign. Reputable licence providers will never compromise their reputation by giving a licence to a rigged casino. Sure, some casinos become rigged over time, but as soon as regulators find that out, they revoke their licences for that platform.
Who are these regulators? In most cases, they are official commissions that decide who gets a licence. For example, in the UK, the most well-known gambling authority is the United Kingdom Gambling Commission. Casinos licensed by the UKGC need to pass a strict test that ensures no illegal operations are taking place.
There are also a couple of “global” regulators that license online gambling platforms, such as the Malta Gaming Authority, which is highly respected in the online gambling industry. Therefore, if you access a site and see that it’s licensed by the MGA, you can be sure that the casino is fair and trustworthy.
To find out whether an online casino is licensed or not, you should scroll down to the footer of the site, where information about licences is usually provided. You can then check the licence number to make sure that the information is not false.
Apart from licences, it’s also important to check who the owner of the casino is. Companies that own online casinos have either a good or bad reputation, and you definitely don’t want to play in casinos owned by companies that have a history of running blacklisted casinos.
Casinos Use Cutting-Edge Security Methods to Protect Themselves and Their Users
Even legitimate online casinos can become rigged if they fall into the wrong hands. For example, they could undergo a cyberattack and hackers could rig games in some way. Luckily, that almost never happens nowadays.

All reputable online casinos use state-of-the-art technologies that make sure nobody can tamper with the games. Moreover, these technologies protect users, their sensitive data, and their funds from all kinds of cyberattacks. For example, every casino needs to use SSL (Secure Socket Layer) encryption to ensure secure communication.
Conclusion — Research Before Signing Up
Online Blackjack Free
We live in the day and age where information travels fast, which is why it’s pretty easy to spot a rigged online casino. They don’t have any security measures, licences, RNGs, and many other things required to operate properly.
However sophisticated, rigged casinos are fairly easy to see through, and that’s why we highly advise you to explore the site before joining it. If you’re still not sure, feel free to read reviews provided by casino experts and users. They’ll provide you with vital information about the site you’re considering, including whether it’s rigged or not.
