There's a slim chance they are not lying - I'll start by saying that - but by disclosing NOWHERE the method they come up with their rolls, based on this one horribly glaring issue, they are not provably fair in the least.
First, in their FAQ they state:
IS THIS A PROVABLY FAIR GAME?
Yes. You can check that every bet is mathematically fair.
Thats it. Thats all the explanation you get.
So lets give it a shot. I took a video of it, just so we're all clear whats happening. The link:
https://vimeo.com/129508792For those too lazy to watch. I open up the provably fair tab, and look at what is clearly marked as the sha256 hash of the seed of my next bet. It ends in 488bec7.
I close the window, and make a roll. Bet ID 44718.
I click on the bet, and see the server seed was 9EpNkr1UAVP4Il9l.
Lets sha256 hash 9EpNkr1UAVP4Il9l... and drumroll please... ef4e962f95fac6266e4bf50580c027d8332048c1a20c7e7c748a5dd7aa12c9b5!
Which is absolutely NOT the hash they showed as being the next hash. And just to give the benefit of the doubt, as some sites double-hash it, the sha256 of the above is f55d30ec00d3de54e2164cf06f8245b33f2ee528c56adb56aa2913fed32e3860.
Also, not what they showed.
They are either lying/cheating, or at best, cheating by omission of the formulas for how their numbers are generated. Don't waste your money there.
