Would you forward me the whole Terms and Conditions or where did you find the bonus?
When it comes to sticky bonuses, they're specific for one reason. Let's say you'll get a 60% sticky bonus. You deposit 100 usd, get 60 usd sticky bonus. Then you'll be playing, maybe get some winnings, but once you'll decide to withdraw it, the initial sticky bonus is always removed from the whole amount. That means they would deduct the 60 usd from your withdrawal.
When it comes to the 75 free spins, it can get even more complicated, because I assume there will be other terms and conditions applied to them compared to the sticky bonus. I'd suppose there will be some wagering requirement, max. bet rule and max cashout applied as well.
