Casinos themselves are attractive with bonus offers etc, but you have to play a lot to be able to make the rollover, it's not easy to reach the stipulated limit and the games don't help much either. Anyway, I've managed to hit the rollover twice now and I've been able to make my withdrawals, obviously it took 4 or 5 days according to the time the casino asks for the deadline, but they paid me correctly and you can trust me, it takes a few days but it's in your account, just be patient.
But I don't recommend betting here, the RTPs don't give a return, most of the bonuses are very low.
