Wagering requirements are a set of conditions that you must meet in order to cash out your winnings.
The vast majority of online casinos have these requirements and the reason they exist is to prevent people from signing up multiple times claiming a bonus and then immediately withdrawing it.
Wagering requirements usually ask that you play through your deposit amount, bonus money or winnings (or a combination of these) a certain number of times before you can withdraw money.
Let’s say you claim a 100% bonus of up to $100. You deposit $100, and receive $100 in bonus money for free.
According to the wagering requirements (example: 35 X), you must play through your deposit and bonus money 35 times.
You will therefore have to place $7,000 in wagers before you can withdraw the money.
Some online casinos have very high wagering requirements, while others do not require you to wager much at all. There are even some casinos with no wagering requirements.
