If you ask which casino, I'm afraid I've forgotten what it was called but the memory of the 100x wagering requirement does go back before. Casinos that don't want to take their business seriously will apply very high requirements so that no gambler can take their winnings freely. And even if the gambler can take it, the casino will apply other requirements, such as the gambler must do KYC but the casino will not agree with many reasons.
This was an insane wagering requirement but I bet this wagering if for claiming bonuses. I think the most I ever encounter is 50x wagering to claim bonus and I avoid it when playing. this is another reason why I seldom avail for a deposit bonus and any other promotion that requires wagering before I an withdraw the winnings. And before the wagering requirement triggers, we should be playing on the bonus so we need to deplete our original deposit before the countdown on wagering requirement starts.
Indeed, casinos with big wagering requirements aren't a scam, but many don't even want to try them because it's too much for them. After all, many of us are not big gamblers and only use small amounts of money so it will be a problem for them.
I beg to disagree, they are not scams, they just don't want to part with the bonuses they give. The wagering requirement is announced even before the player avails of it. So there is no way that the casino scammed you when you agree to the term. It is your decision to take it or not.
