I've always wanted to know if they really pay $271.37 on average for 10000 rolls. And if so, why don't they just pay $0.027 for each roll? They'd have the highest paying faucet, while it would cost them the same amount in total.
Yes, we do. Check the stats pageQuote
Interesting. It would be interesting to hear statement from wetsuit or TheQuin.
I find it interesting that for years they haven't responded here.Quote
It was created to allow you to verify your own rolls. It gives you the evidence.
The user can't verify the roll when server seed hashes are replaced:Most of them are fine, but 2 times happened that, after the roll, server seed hash was REPLACED with a new one, while nonce and client seed where still the same. This completely break their fairness, since replacing the server seed hash means that they are replacing the server seed and therefore they are changing our rolled number. 
What it doesn't do is give me the ability to prove that we didn't cheat.
That is exactly what provably fairness is meant to do. If the user can't use it to prove cheating and you can't use it to prove being honest, the "provably fair" system is "provably worthless".Quote
Most of them are just using stats to prove that variance exists
Can you provide stats on how many freerolls have been played since the site was created, and how often each number came up?I just won $20 at FreeBitco.in! 116 times

You assume every top winner will inform the world of his winning roll in that thread, but that can't be given for granted.I just won $200 at FreeBitco.in! 2 times
