You should provide the coins to a trusted escrow, the amount of 1dice1's balance and deduct it from his balance. After a reasonable time has passed the escrow releases the funds (I'd say a couple days) to 1dice1 UNLESS you provide proof that he cheated. You delaying his funds is truly unreasonable 100%. If your excuse was true then you should be working 24/7 into his case. Not getting offline and coming back every 12 hours. Should be around the clock if you are really going to delay payment.
I personally played at everydice twice but after this definitely will not play ever again here. It is bullshit what you are doing. It has been 3 days. If you worked 24 hours straight I guarantee you would have your decision by now.
Checking that provably fair system is works might not take a long time, but other than that we did many things. One of the example is the leak of site seed, this not only involve technical checking and ensure our server has not been compromised, but also questioning all team member involved in the project. We cannot assume this is the case (and lets not), but it is better to be safe than sorry.
As you might noticed, few hours ago the site profit goes down ~50 BTC again, this happened after some manual withdrawal. We know that the previous bet event is mathematically unrelated to the future event, so thinking that site will win after losing is fallacy, however, this is quite much for a coincidence. We are really sorry for the inconvenience, but for a moment we will have to ensure everything is legit. The roll function of P-4747 and 1DiCe1 also has been disabled.
EveryDice, it has been more than 24 hours, you must pay 1Dice1. Period.
I run a scratchticket gambling site. When I started my site, I was fully aware of the risks that variances mean to the house bankroll. On my site, I have a background process that runs that tells me when a betters results (wins/losses) are exceptionally lucky. If you are outside 4 standard deviations from the norm, that's pretty damn lucky. These results are flagged for manual review. However, unless I can PROVE fraud within 12 hours of so, I must pay out. This is the risk the house takes when it develops (or licenses) its software and puts in place its security procedures. If someone rips you off, than it is still your fault and if you can't prove fraud within 12 hours, pay him. This is the cost of business. When you find out how they did it, fix it. But for now, you are completely killing your own site by undermining every ounce of trust everyone has in you.
My guess is that if I ran a statistical analysis on the betting history you released for 1Dice1, it would show the guy (gal) is damn lucky but statistically within the reasonable realm of possibilities. Pay him unless you can 100% prove fraud.
