I didn't try Blackjack.fun, I see their signature but never had extra free time to try them... How it's in their poker room? Are there players? How do you like them generally? Maybe I will try them if I hear something positive from you...
I had a great time participating in some poker tournaments over at Blackjack.fun though you won't always find human players to play with. I also participated in some of their blackjack contests though I never won anything big so far.
The site itself is smooth and there are issues now and then, but they get rectified pretty quickly. Pretty good crypto gambling site so far in my opinion.
