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

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.

Payout time! 

Thanks for joining.

The example I quoted in the previous reply was almost exactly (except I changed the number to A,B,C,D) what we've been told in the email. We take all the reported bugs seriously. The reasons we initially dismissed it are:

1) We've received many similar emails who claimed they saw a "pattern" in card dealing. And the one your friend sent is exactly that.

2) We know that no such pattern exists, all cards are randomly shuffled and the shuffling system is exactly the same for blackjack, baccarat, or video poker. Anyone can prove our fairness with our provably fair system, without reviewing our code.

3) The issue did not gain much of our attention because we didn't lose any bitcoins from your friend who, as you said, been trying to exploit it. The reason behind that, as you mentioned, is there's a flaw in our card system that favors the dealer. And as I mentioned in 2), we know that our card shuffling system is fair and random. Hence the dismissal.

However, with your continuous insistence that there is a bug, I've requested more information from your friend with a promise of bug bounty. And if there's such a bug, rest assured you'll be generously rewarded.

For your card shuffling question, I've passed them to our tech team and they will answer you shortly.

And as we speak, one of our technical team is working on processing the raw data (to show the final state of the game) to aid your statistical analysis.

Really appreciate you answering in this thread (and your previous reply on clarifying provably fair). 

Sorry I just saw this. Our team (including myself) are busy working on something big and couldn't spend as much time on the forum as we like.

Anyway, we did receive your friend's request for the games and he should have it by tomorrow. We're always willing to send players their historical games and even encourage them to post it on the forum so everyone can see it.

Regarding the reported bug, I passed it to our team and they dismissed it as purely coincidental (confirmation bias). Basically this is what's been reported:

1) Dealer has card A and card B
2) Player has card C and card D
3) The next card for dealer has to be card E!

Our cards are randomly shuffle (and have a similar shuffling system for all card games like Baccarat, Video Poker) with the outcome directly control by the player with the player seed he's able to enter. Everything can be easily proven after the game with all the information we've provided: https://coinroyale.com/provablyfair
We made the page easy to understand and more than happy to walk you through step by step to verify the result and explain how it works (it's a beautiful system).
