Why did you even reply to this post. This topic has been dead for over a year. I don't understand why people find these old threads and bump them for no reason. I don't know if this site is still reliable. Their website is still up but looking at the amount of registered users makes it seems like it might be a fake scam site.
I think new provably fair system which is the reason people bump it from the graveyard. May be you should try to check on their website sometimes. See how they make their lottery system provably fair, and about their hi-lo games, I do not think that it is a scam, they just have huge house edge so it is provably fair too
