Do you have the code that's used to convert a hash into a game result? From that it should be pretty easy to compute the house edge. I couldn't find it on their website.
They are clearly not a good actor. They have a history of software-piracy, faking stats, not caring about their reputation, etc.
I took a look at their seeding event:
https://bitcointalk.org/index.php?topic=5133118.0and it's done in a way that proves nothing. Hard to say if it's intentional, or incompetence. But considering all they copied bustabit's seeding event and then removed the part gives me pause. For the seeding event to make sense, you have to commit to a hash chain
and how to interpret the hash chain. Or it's all for nothing.

So I guess, why even bother with them? There's like a dozen legitimate bitcoin casinos that run a fair business well, why screw around on the one that's nothing-but-red-flags.
Then this site should not be trusted they already faced so many negative issue so it is enough reason to stay out on their site,
Beside there are so many trusted sites that you could play don't even bother spending money or your time to those untrusted site like this.
