well let not be too quick to congratulate the ops as he needs to prove that with a winning from reputable site e.g. Butadice for us to be sure he has that skills to break the probably fair system.

I don't assume that he has found a way to trick the probability calculation and thus found a strategy that gives him constant profits. Such a thing is only possible if he would have found a bug on Bustadice/Bustabit that he exploits. However, since both casinos have been on the market for a very long time and hundreds of thousands of Bitcoins have been gambled away, I think this is also unrealistic.
