1- Obviously you are not understanding correctly, we know if the dealer is Pat or will take a card BEFORE the down card is exposed.   

2- I am glad you know that a dealer needs to hit until he has a 17 that is invaluable info to have

3 - As for the comment about variance, we have played in excess of 15,000 hands at this casino and have the data from 12,000 of them that was given to us by CoinRoyale.  

Last point, we do not care about the bug, refer to the post above.  We have not accused anyone of cheating at CoinRoyale.  We are simply saying that we know of a bug that gives us an edge and even after playing 15,000 hands we are not winning even close to half of the time.  Therefore we are saying that there is a potential problem with the game, most likely in the shuffling.  

We are trying to work with CoinRoyale to figure it out, and have asked appropriate questions that have not been answered yet.   

If you want to think that the software is PERFECT and that there is NO WAY possible the shuffling could have an issue then I'm happy for you.  Maybe we need to get these guys jobs at Microsoft or writing a True Random Number generator since no one else writes perfect software or has figured out a true random number generator.

It seems you do , based on the references below that you keep on insisting that there is a bug that give an edge to the player but you are getting more losses then wins. If you simply dont care about this then there is no point in discussing this further isnt it? but the fact is that you keep insisting that there is a "problem" . 

If you will enlighten the conversation here, how many percentage of edge are we discussing about? Either way there will be two scenarios later , the former will be that there is an issue with CoinRoyale shuffling method and the later is that there is no bug that you give you an edge . I am merely more into the later option though Im eager to see how this turns out

Victorhing, you and your team did not read the email correctly.  The example you gave was not what was implied in the email.  I am ok if they dismiss it, I guess you would prefer that the bug be released to the public.
The bug allows the person to know if the dealer has a pat hand or will need to draw, and it also allows the player to know who will win the hand before it is played.  This is easy to take advantage of by doubling down on any hand you know you are going to win, thereby giving the player an advantage.  The only flaw in the game is that the cards seem to be dealt on the dealers favor more than a random amount.

I am not only looking into the actual cards dealt, but also how the cards were dealt - For example, here is a quote from your website regarding Fisher Yates

"We first hash the Player Seed using SHA-256 and truncate the result to 32 bits. That becomes the seed to the Mersenne Twister PRNG. We use the seeded PRNG as the random input to our Fisher-Yates shuffle, which takes the Initial Deck to arrive at the Final Deck."

This is a quote from the Fisher Yates wiki which you link in your website.

"many programming languages and/or libraries may often have only 32 bits of internal state, which means it can only produce 232 different sequences of numbers. If such a generator is used to shuffle a deck of 52 playing cards, it can only ever produce a very small fraction of the 52! ≈ 2225.6 possible permutations. It's impossible for a generator with less than 226 bits of internal state to produce all the possible permutations of a 52-card deck"

How it is possible for your system to not only shuffle a 52 card deck effectively, but to shuffle 4-8 decks adequately.

So looking further into it, the Mersenne Twister has a problem, which may account for the large number of 20's that the dealer will run in succession.  Here is the problem with the Mersenne Twister - 
"It can take a long time to start generating output that passes randomness tests, if the initial state is highly non-random" and then it says "will usually output nearly the same sequence for many iterations, before eventually diverging"

So I was wondering how you work around the limitations of both the Mersenne Twister and the Fisher Yates Shuffle.  Once again, I am not making accusations, just inquiring about how the shuffling actually works.

It would be nice if you would read the few older post before posting this again. Just because the cards repeat doesnt mean something fishy is going on , simply just note down the hashes before you play and verify it after you play ( which obviously takes less than 10 seconds to do so ). However it is quite unlike for the exact same cards for both dealer and player to be dealt again ( the 4 first card could be the same however the next one after that would obviously be different )

Just for some clarification regarding the bolded part. Having provably fair mechanism doesnt mean that the gambling site wont be able to cheat you , in fact the thing with this provably fair is more like an insurance for the player which incase the gambling site tries to cheat then the player will know it . Also regarding them advertising provably fair is pretty much not weird or suspicious as it is a pretty much industry standard around here

P.S : To clarify some off topic things, Im neutral in this case and just providing some blurry things around . Im not part of CoinRoyale nor a shill of them

Did you read reddit article posted by StatsMan there are many ways to manipulate outcome when result is still provably fair and player can not notice... i see players complain there that they lost bets after they had to refresh page ...

We actually found a great write up about how this "Provably Fair" system is easily bypassed by the Casino.

That statement is incorrect, they can cheat you and you would never know it, even with the Provably Fair mechanism in place.

In fact, we have screen pictures of it occurring, on that occasion we did notify CoinRoyale and they refunded the 0.5 BTC but we have no idea of how many times it happened previously.  That is why we have been monitoring closely and last night when it happened again and we reloaded the page the cards were in a different location and who knows if they were the original cards or not.  We did monitor some activity from their server and it appears we were cheated on those bets as well.

Holy shit. This is serious! No response from victorhing yet, either? Hmmmmm.

Sorry for the late response guys. I just saw this  Like I said earlier, our team are sprinting for a new project and didn't spend as much as time on the forum as we'd like to. Anyways...

Statsman, regarding your earlier question of shuffling, you are right about our Mersenne Twister (MT) truncates to 32-bits. However, our dealer shuffle doesn't just use MT and Fisher-Yates, it also uses the Java RNG and therefore the process as a whole has enough randomness.

Oh, you're talking about the 0.5 BTC? Yup, I remembered that. You sent us screenshot of the cards not loading correctly (which we assumed probably some cache/client connection error), and I refunded you the wager + comp immediately as a gesture of customer service. Despite your "mission of exposing us" (as you mentioned in the email), we still think you are a loyal customer and still intend to treat you like one

One example, the "Stalling" technique that is discussed on the reddit link happened to us tonight - not only once but twice.  I think the second time it happened it was on a .7 BTC bet, of which we lost. It not only stalled, when it was reloaded the cards were in a different circle then the original.  We have seen this happen many times over the weeks but nothing like we have witnessed the last few days.

If you reload the cards and the hands are in different circle, perhaps it's a front-end bug. I did try to reproduce it just now but couldn't. (Feel free to send me a video/screenshot if you successfully reproduce it). However even if the "reloading" bug exists, the hands should be still the same (as the hands data sent from our backend API remains).

In regards to the .5 BTC - I did state you refunded that amount, I was eluding to it happening 2 more times last night and the second time it happened it was on a .7 BTC wager.  

About the MT comment - instead of writing it all out for you I will quote TrevorXavier from reddit.

"When the second round of shuffling comes into play with Mersenne Twister ("MT"), I am genuinely concerned about the poor distribution quality due to frequent reseeding. MT is known to suffer when poorly initiated (see the original paper), and randomizing a deck first with a stronger random number generator before MT does not imply it will be immune to a poor reshuffle, as MT may not exhibit uniform distribution across multiple reseeding operations. Many statistical tests will be needed to confirm this from a fair-game standpoint, so at this point I only consider it a "concern" and not a proof.
So, you make a wonderful point. It may actually be better to use a primitive for the "cutting" of the deck before dealing, rather than an algorithm. As libertaad stated in another comment, it looks like he intends to push bitZino away from MT and onto something different.
Thank you again for your excellent comment. Very good points made."

FYI - libertaad was the guy that came up with the system used by CoinRoyale and was the owner of BitZino.  Liberated also stated that the MT was going to be changed because of the limitations t has.

The points above are exactly what we stated prior to finding the write up.
