What is wagering?

Wagering is a term used for betting money on any of our online casino games. We also use the term wagering requirements in most of our casino bonuses and promotions. An example of how this words is as it follows:
If you received a $/€10 bonus and the wagering requirement on that casino bonus is five times (5x) the amount, then you must wager (bet) at least $/€50 before you can withdraw your winnings.
