But sometimes there are contests like $50 free spins but to qualify you have to have a wagering requirement of around 30x or 40x. Yes this sounds silly but I think maybe they are scam casinos or newbie casinos who don't know how to market.
To qualify or to unlock the withdraw? I've never seen any free spins promo where players need to wager 30-40x just to qualify, most free spins comes with 30-40x in order to unlock the bonus into real balance. How can a casino be a scam just because the casino give the free spins with 30-40x wagering requirement? This is common thing in this gambling industry, if you think any casino with free spins offer with 30-40x wagering requirement as scam, means that there are so many scam casinos out there. We cant judge a casino as scam because such offer because it is something usual.
