Casinos use them as a promotional tool to give new players an incentive to create an account and start playing. No deposit bonuses make it possible to essentially gamble for free, but their values are generally low. With 50x wagering requirements, you’ll have to bet more than 184.50 in total to be able to withdraw your money. This means that if you got 10 of free credit, you’ll have to play for example 1000 spins at 1 each to roll it over.
