Sticky Bonus and Non-Sticky Bonus explained
When choosing an online casino bonus you will essentially come across two different types of bonuses: the common Sticky Bonus and the rare Non-Sticky Bonus.
The sticky bonus is the most commonly bonus found. When opting for a sticky bonus, your deposit will most likely be matched with a 100% Casino Bonus, sometimes even higher. You are then required to match a wager requirement, which is usually around 30 to 50 times your bonus balance.
Quick example: You deposit 100€ and get 100€ Casino bonus on top with a wager requirement of 40 times the bonus, you are required to wager a total of 4.000€. The sticky bonus prevents you from cashing out your balance until these wager requirements are met.
Non-Sticky Bonus (Parachute Bonus / No-Sticky Bonus)
The non-sticky bonus is very similar to the sticky bonus but with one big difference: your real money balance and your bonus money balance are split. This means that, usually, you first play with your real money balance before your bonus money comes in play. With that being said, the non-sticky bonus allows you to cash out any profits you have made, as long as you did NOT touch your bonus balance. As this sounds quite lucrative, non-sticky bonuses are pretty rare.
Quick example here as well: You deposit 100€ and get a 100€ non-sticky online casino bonus on top, which sums up to 200€. Now you have 100€ as real money funds and 100€ as bonus money funds. You play until you reach 150€ and all of a sudden you win 500€. You are now allowed to cancel your active bonus and keep your real money balance of 550€.
