I have seen some weird stuff on bodog over the years, both at the NLHE tables and more so in the casino. No empirical data, just patterns and losses, losses, and more losses: For example, in the past 100 BJ hands, the dealer has started with 20 47 times, me 19, and an amazing 12 of those times were pairs of tens or higher... I know this sample means very little, so I won't continue with my speculation, but has anyone else felt like something was wrong in the casino?

What patterns?

Variance.

Chances of Bodog being rigged <<< chance of you being a moron

played bodog blackjack several years ago. Thought there was about a 95% chance it was rigged.

I would bet you a large amount of money that this didn't happen on Bodog or any other site, ever, if you had any way to prove or disprove the claim.

You have no idea what you are saying with that claim. Suffice it to say that if the game were rigged, they would never be so stupid as to allow something like this to happen. I won't confuse you with the math.

Why should any site make their blackjack rigged?

To be fair AP/UB did manage to rig Keno.

lol @ AB/UB

Probability of dealer starting with 20 is 18/169 assuming infinite decks or a shuffling machine. Probability of a 18/169 even happening 47 times in 100 trials is pretty much zero.

You prove this happened, I ship you $100.

There's a lot of different thinking in this area -- but I think you're a little too liberal with your theoretical probability of zero.

I'm pretty sure the chance of dealer starting with 20 is 136/1326 which is almost, but not quite, the same as 18/169.

At any rate, we can calculate the chance this happened 47 times out of 100, and the chance it happened 47 in a row. And "pretty much zero" is a very good description of both probabilities. The first one is roughly 100 quintillion to 1, and it is far more likely (26 zeroes more) than the second case.

It's a very safe bet that neither of these events will ever happen (randomly) in the entire history of the world. It's also a safe bet that OP made it up.

Chance of 136/1326 event happing 47 times out of 100:

(136/1326)^47*(1-136/1326)^(100-47)*(100 choose 47)

My regular iPad calculator bombed out on the first term and said zero.

So I pulled out the HP48 emuator and got a probability of 8.96e-21

Yeah it's not zero but it's pretty negligible.

Spadebidder and Neil S --

How are you interpreting this statement by the OP --

I was only responding to the part that says the dealer has a starting hand of 20, 47 times in the past 100 hands. The statement was pretty unambiguous. As Neil and I both pointed out, the chance is less than once in 10^-20, which is quintillions. That many blackjack hands will never be dealt before the sun burns out.

I don't know why I threw in the extra bit about 47 in a row, I suppose that's irrelevant.

But the statement continues ...

The second half of the statement made me think that the word "starting" was incorrect. Either way, the statement is much less than clear.

The lack of clarity is what I was addressing when I said --

I didn't work off of OP but rather where Spadebidder said

I wanted to see just how close to zero it really was. And 10^-21 isn't bad.

Try and get the idea of patterns out of your head. I used to be convinced that I "KNEW" how the bodog roulette was wired and I made a fortune playing my system!!

I then lost it all back trying the same system...it was crazy...

I then won some more playing my bodog system, and it worked

Then I lost it all back again...

Its hard to distinguish luck from patterns because we understand patterns, not radomness. I once showed someone me making a straight up bet on their roulette saying that categorically it will be black 6, and it was, they thought I was a genius, and so did I...until it didnt work out that way!!

I can not prove it bc they refuse to send me the audit of my casino account with the spread sheet that every RTG casino has... But I knew it was unlikely to have 19 as I had, most of which were bested by their 20's, and I also knew it was nearly impossible to have pp of tens or better 12 times, but I sh#t you not... Needless to say I dont play there anymore, I wish I had taken a screen recording... The only thing I can offer to explain the situation is that Bodog admittedly has rewritten the orig RTG code... And the software is constantly 'updating' during sessions. Posts web-wide complain of hot streaks and winning sessions cut off by one of these auto-updates. Why couldn't they change the 'randomness' of the game in the middle of a session if they so chose? They have made the slots there tighter than any other RTG on the web... And they are constantly publishing huge $100k plus wins from supposed customers, but I never read about these wins in posts from the actual clients...
And maybe more significant than any of my claims, which admittedly come sans back up data; bodog recently added a bunch of games from the proprietary software package originally produced and used on the Luck3.com website which was one of the old cake poker rooms. Many of you might remember how legit they were? They were taking CC deposits for 2.5 months this past spring with no CSR's and no intention of paying out... Not until a consolidated buy-out of their debts and clientele by Juicy Stakes (a newer cake room) did any compensation ever get made, and that was after two months of no customer support...

I've never played the blackjack there, but their sports betting odds are great.

I noticed when the dealer starts with 20, he has a pair of tens or higher almost 100% of the time.

I assume you mean any two 10-value cards and are being sarcastic, but a 20 on the deal is actually A9 13% of the time.

The only casino games I thought were rigged were on the Merge Network.

I use the phrase "pretty much zero" very carefully.

The owner is sketcy, he has been in legal trouble and I've seen a show on him and he just gives off a bad vibe. I'm not saying the games are rigged but I certainly wouldn't play there even if they allowed Canadians.
