Coinroyale doesn't seem rigged to me. I played a bit and the win/lose ratio seems to be very close to 50%. I think I had about 55%-60% of my hands in BJ were wins.
Me too, I don't think coinroyale is rigged either. There is a provably fair system, which you can verify the fairness.
Once I found a bug and reported, I got a 0.1btc bounty, very nice site.

Signature campaign is nice too.
I hope CR will have more promotions like other sites, 100% deposit bonus and no deposit bonus are both profitable for casino.
