A non-sticky bonus (also referred to as parachute or or risk free bonus) separates your real money from the bonus money, allowing you to cash out your real money without having to fulfill the wagering requirements (WR) linked to the bonus money. In this scenario, and by default, you would first start playing using your real money, and would have the opportunity to withdraw it at any time, before tapping into the bonus sum or having to wager it. If you are still playing with your real money, you could decide to make a withdrawal and cash out, which in turn would forfeit the unused bonus money in order for you to do so.
In contrary, a sticky bonus will lock deposited funds respectively the real and bonus money balance cannot be withdrawn any time until the wagering requirements have been met.
