I’ve had issues with Casino Rewards before, and it took a long time for the problem to be resolved. all these issues were resolved after I filed complaints to Ecogra. this casinos group is reputable and generous, but sometimes they look for reasons to avoid paying out.
Back when I played at All British Casino, I had no problems, for me, it was a good casino. unfortunately, I can no longer access this casino because my country is now restricted.
Congratulations @marius1978 ! very nice wins. you're going through a lucky period, enjoy it while you can because periods of good luck are shorter than periods of bad luck. That's what I believe.
Once the bonus conditions are met, you can only withdraw 10x the bonus amount; even if you continue to play and accumulate a significant amount, you can only withdraw what is specified in the bonus terms and conditions.
Most online casinos require a minimum deposit to withdraw winnings generated by the bonus. The maximum withdrawal is usually set at €100. So I think depositing €100 to withdraw your winnings is excessive. I don't know this casino, but you should be wary of casinos that require a €100 deposit for account verification.
