I'm so surprised to see most comments above my post are agreeing/supporting the accusation against coinroyale just based on a story and screenshot. In general, to prove fairness on a site cant be based on just a screenshot. I'm not trying to defend casinoroyale but it is general understanding that I know about provably fair.
OP, you need to prove it with valid proofs then post it in Scam Accusation board. I'm not an expert of provably fairness but I believe there are many forum members who knows how it works so they can help you and all pf other users to know whether the site is provably fair or not.
