To clear up the the situation with paying sjess:

Most of you know that there was a fault in the provably fair system.
This allowed anyone with computer programming experience, that had studied the provably fair code, to realise that rolls were biased in favour of "Hi" bets.

sjess, a programmer or working with a programmer, wrote a bot to take maximum advantage of the flaw.
sjess couldn't know the result of any rolls made but knew that given a high enough starting deposit, betting a small percentage of their balance and putting in thousands of bets that they would most likely profit in the long run.

sjess started with 5 Bitcoin and bet very small for hours, making over 38,000 bets, all while risking a small portion of their account balance.

sjess knew full well about the flaw and deliberately tried to steal investor funds.

The decision has been made to not pay out sjess the unfair winnings.
All rolls made by sjess have been reversed and investors paid back 19.4 Bitcoin.

sjess has received the initial 5 Bitcoin deposited.

This decision is final and in future anyone who takes advantage of any software flaw will have their entire account balance seized.

The flaw has already been fixed an the site is running as usual.

This unfortunately meant that some players would have lost unfairly. This flaw affects roughly 4.6% of all "Lo" bets.
Refunds for these bets will be issued to players today.





As a side note to the posters in this thread who have mentioned that some casinos would pay out even if they knew the player took advantage of the system.
There is no casino/sportsbook, live or online, that I have played at or been in that would pay a player who done this.

Two of the largest casinos in the UK, William Hill and Bet365, state in their terms and conditions that they would not allow this activity and would freeze funds and close an account:

William Hill:

Bet365:

Can you name those developers so we can avoid them as a community? They are clearly not qualified to be working in this area of programming.

The provably fair code, as some know, was the only part of the site I outsourced. To a trusted developer I knew who I was hoping to bring in full time to help out. Reviewed by another developer I thought I could trust who was also going to be joining full time.  

It was actually on my list of things to review over the next few days as I wanted to get provably fair working for Blackjack.  

So yes, I could have done more tests on this and not just rely on the word of what was to be my "team" but it's certainly not something that would have went on for months unnoticed as some suggest in the chat.

Lessons learned. People who lost unfairly are being refunded and things are back to normal.

Will post a more detailed report after I do the final refunds.

yeah, sad but true.

looks like you have no other choice than to get back into the pit to safe us all  *pretty please*

Thanks.

Turns out I had heard about it before but hadn't heard the details.

It's surprising how many ways there are of copying JD wrongly

*bumpy bump*  just to make sure that the question won't be missed.

I can't remember where I read it specifically, but they were exploited and plan to pay investors back over time from their commission.

Dean is probably still in bed after the fuck up yesterday but everything on PRC seems to be business as usual. Fair play Dean for sorting everything so fast.

I missed that one. What's the story there? Did they get exploited too somehow?

Thanks dean for the work.
Any wallet to send a tip?

When someone invests in such ventures. They are investing in the house(said clearly during investing). So, I believe if house has to take any hit due a mistake, then investors have to accept it too. Since majority of the people in chat are investors, the decision was probably taken to roll back the bets. Its not right, but not wrong either since he knew about the flaw.

Sjess knew about the flaw and admitted knowing it.
The Funny part is that despite it being obvious that bets willbe/were rolled back, sjess has not asked for his winnings. He seems least worried about the coins. 

It's a difficult situation indeed. Assuming the player had no idea they were abusing the site then the proper thing to do would be not to punish said user. As far as passing off the burden to investors, this sort of thing needs to be clarified at time of investment. If there is some sort of terms and conditions/FAQ for investment that specifically states that investors would take the hit, then it would be just.

It is the right thing to do definitely from a PR stand point, but I wouldn't take it from the investors.  In the Dooglus example if you are going to refund the users that bet on black because they did not notice, then you need to refund the investors that bet on black +1% too, because they weren't given the advertised odds either.

Offer to pay Sjess by giving him 50% of the weekly commission until paid off and move on.

I would honor those bets, it is the right thing to do. He had advantage but not cheating, since it would be my error.

It's a tough call.

Suppose you accidentally run a roulette game where 60% of the numbers are red due to a manufacturing error.

Some guy notices and plays for 15 hours non-stop, betting on red over and over, and wins a bunch.

Are you obliged to honour all his bets, even after he openly admits "I saw there were more reds than blacks, so I bet on red a lot"?

I don't know the answer.

I do think it makes sense to refund the people who bet on black and lost due to the error, but it's less clear what to do about people who won a bunch on red. Some of them didn't even notice the error and were just playing 'red' because they like red, but others were clearly playing because they saw they have a positive expectation.

I guess the right thing would be to pay him out, and take the hit. Whether to pass that on to investors or not is a separate question.

Has there been a statement about exactly what bets have been / are going to be rolled back?

What's the deal with the sjess account? Is he just out of luck?

Thanks for making this right Dean.

Got everything back in full. Dean has quite literally worked non-stop since the issue happened and has made everything good.
