Probably okay
These casinos seem okay. The vast mass of evidence points to their integrity. Personally, my experience has not been great.
I must have wiped out at Inter eight or nine times in the last year. I am actually behind over my playing life there. This is probably just bad luck, everyone else seems to be getting a fair game, and given the amount of casinos I play at its likely I am going to be booking a loss somewhere. Oddity: I play at cryptos under my author name rather than my real name, so its possible someone flicked a cheat switch for the advantage play author.
I have won money at CON, however I was a little annoyed by a random security check at Cassava enterprises, which required me to send passport and id, which they failed to receive. It is really irritating when people ask for ID, can't open a JPG and turn off their fax machine, whilst holding thousands of dollars of yours. A tip here: talk directly to CON personnel who move heaven and earth to help you, the parent operation is by comparison slow and/or useless.
Personally I'd rate the better Boss media operations and William Hill slightly higher than these two, though the bonuses are limited here.
