If the site claims provably fair, post it, I'll review it.

If they don't claim provably fair, they are stealing your money and there's nothing you or anyone else can do to prove otherwise.

Won't out the casino since sample size is too small. Undecided

Spreadsheet of dealer hands





Takeaways:

69 hands
Dealer Busted 13 times - 18% of the time - expect ~28%
Dealer 21 - 8 times - 11% of the time
Dealer 20 - 7 times - 10.14% of the time
Total dealer 20 or 21: 15 times - 21.73%
Dealer showed 10 or A 42% of the time  Cool
Dealer Bust: 18% Dealer 20/21 - 21.73  Roll Eyes



Sample size small, pretty sure they are cheats, won't invest more money to do a real test....

Rigged software is out there...always be cautious.

I don't think you can make that kind of call until you have played a few hundred or even a few thousand hands.   The more you play, the closer your average will be to the expected expected statistic.

Well if it isn't Provably Fair you should just out this casino's name?

like i said before, this sample size is useless, a sample size of under 100 hands is in no way determinant of fairness or unfairness. you would need at least 100k hands to have any meaningful data to analyze, and drawing a conclusion from this data would be inconclusive. no need to fire off an accusation without being 100% sure.


Maybe for Blackjack it would require a large number of hands but I'm not so sure.

I know you can run a Chi-Test on Craps and if it is blatant cheating you can notice within a few hundred rolls without a shadow of a doubt.  Roll Eyes you should see Michael Shackleford(Wizard of odds) and his test on BLR technologies craps...


I don't care to take this testing this much farther, I guess just stay on Provably fair casinos and always change client seed...all you can do  Roll Eyes

As for the question of was this a "provabaly fair" casino - NO, tried something different...my bad I guess  Cool

Playing on a non-PF site is just asking for trouble IMO.
Not all PF sites are doing right things (eg. dicebitco.in), but at least you can try to verify the bets and can be sure if the site is cheating or not.
On the other hand, when you get incredible rare result on non-PF sites, there is nothing you can do. It could be purely luck, or may be not, who knows?

I think the only fair BJ can only be found in live dealer.
but your sample size is too small to say they cheat, maybe you just unlucky

id say 777coin's blackjack is fair too, ive won some and lost some, seems fair to me.

 Grin
me too, able to won some at the end on 777.

People usually think of 'unfair' when losing on computer, but actually it also happened in 'live dealer' too,
like dealer got 21 with a '5' opening card, it always happened,
I would say unlucky rather than unfair Wink

this is a pretty small, and by that i mean ridiculously small sample size to make any judgements or accusations off of, maybe after a few thousand hands at least you could start pointing fingers.

There is a thing called variance, it might cause the outcomes you get be distant from  the mean.

Is the casino provably fair(you would never bet in non provably fair casinos with any significant amount of money), is it live?

yes of course there is variance, of course sample size is small, results mean little.

I had made 4 deposits to the casino in question and all had nearly identical results, I only decided to record on the 4th deposit since I was shocked at how blatent it was...I regret not recording all the hands over the 4 deposits.


As for the question of was this a "provabaly fair" casino - NO, tried something different...my bad I guess  Cool



Also curious and perhaps discussion for another topic is why all the provably FAIR blackjack casinos only allow single hand blackjack..besides softswiss(of which I've won alot on)  Roll Eyes

in what site this happen
cause till now this proves nothing , the stats you have provided could happen anytime
how about if you win 20 in a row , or dealer was busted like 6 in a row , would you post that
sometimes it's all about luck , but if you think really that this is unfair then you should do your research about the site
