Remember Satoshi Dice? I remember this game blew my mind years ago when i first played it.
But recently I've been wondering are they truly "provably fair" as they claim to be?

The seed's hash is provided and they show that the seed value is random but I haven't been able to make the connection that the seed is actually being used for the dice roll..

Is SD truly a provably fair game?
