The free spins won't allow you to win anything. It is just a promotional tool to draw you in so you play more. Its just like how casinos will givep layers free rooms and free food so they stay longer and play. For whales they give them the most ridiculous perks and even let them fly the casino's private jet just so they bet millions.
This is very true because usually with free spins you need to meet their minimum amount which is more likely the case too high to reach before you are able to withdraw.This is the caveat which come with these free spins. The player usually ends up using all their free spins before they reach the requirements and they end up depositing instead.
It is like a welcome gift but the casinos find a way so you can not withdraw if you end up winning anything.
It is all part of their allure.
