haven't tried those, but in my opinion, the best crypto-gaming site I use who offer instant withdrawal is vegas casino their tons of good services really attracted me and my friends, now we all have the same best site to play and spend some with while doing fun theirs. Besides this, they offer a 150% bonus on new depositors that's a really a great deal to steal and maximize the BTC we deposited there. Plus don't forget they offer a variety of games and they all are just awesome as I tried like most of them but slots and blackjack are my favorite one there.
