I have been playing at CoinRoyale since 2014 and lost many games at low stakes at the beginning and I was thinking they are cheating even with implementation of provably fair, but they reassured me and show me everything I asked for (hand data, guided me trough provably fair system, they even learned me how to play better), since then I had not any problems with them, when I was losing they credited me comps they even sent comp to my personal address. For every bug submitted I received a bug bounty. Received big comp for testing their new games. I got an answer on every email I sent to them.
If game freeze and you refresh page cards will be on first sit and client seed for new hand will be randomized.
CoinRoyale is the best!
