Many online casinos offer welcome bonuses to incentivize new players to sign up, but in order to avoid just giving money away, they have stringent requirements when it comes to letting players withdraw any of that bonus. This comes in the form of wagering requirements, which is the amount of money you need to bet before you can withdraw your winnings. Often, the wagering requirement is between 30 and 50 times the original depot you made, plus the bonus amount.
