Yes. I too believe that is what a sticky bonus is.
But this casino has a completely different set of rules.
For example, if you deposit $100 and get a $100 bonus,
combined, you start with a $200 bonus.
When you meet the wagering requirements, you have $150.
Then, the first bonus of $100 is subtracted from that,
Subtract the remaining $50 from the first $100 bonus, which is $50.
As a result, this $50 is said to be the sticky bonus,
In fact, it immediately disappears from the balance, leaving only $100 in cash.
And the higher the percentage of the bonus, the more of the balance that disappears.
For example, if you deposit $100 and get a $200 bonus,
combined, you start with a $300 bonus.
Suppose you have $200 when you meet the wagering requirements.
Then, subtract the first bonus of $200 from it,
Subtract the remaining $0 from the first bonus of $200, which is $200.
And there is no cash left because the $200 is immediately eliminated from your balance.
I have been to several casinos and this is the first time I have seen such a complicated system.
The casino claims it is a sticky bonus, but it is almost a scam.
