At risk we're going to get off topic, as again the issue isn't in specifics.. the bonus cash is bet first. While it has a condition of a sticky bonus, in traditional terms sticky bonuses are reserve funds that are used only after the balance has been lost. You get a chance on going bust to use the sticky funds to win your way back to the positive. If so, can cash out the difference of cash less sticky remaining, but only if have met the generally large rollover terms. In general use, these have been the lowest value type of bonus. It has similarity to free play also, except bonus stake is returned, and then is used again as first stake on next bet. Therefore it functions much more like a cash bonus with a very minor caveat attached than it does free play or sticky. Again though issue isn't so much with the specifics, but is as explained in write up provider earlier.
