Not that big of a loss actually. trust me. I got the same some hours ago (50 spins of 0.20$), won 3$ from it

and these 3$ you have to wager 35x to clear the bonus (max profit 20$), and this is only possible on some (not so good) slots. Those 3$ with the minimum spin of 0.20$ were gone in 17 spins, turning over 3.40 of the required 105$, hahaha.
So there is a super tiny chance you actually make any money from these. If the region thing doesn't work for you why don't you just use a VPN?
It is still free and experience is what I am actually after and not the possible winnings. Haha
As you can see, there are users who have access to features where they can get a bonus of FS as long as they deposit even a small amount for the last 7 days. They also have the spin, which is not available for me, even after I confirm it to the support team. Though, that's actually fine since we have nothing to do with these restrictions per region. That's why when I received a bonus with no deposit needed, which does not usually happen for my account, it makes me excited. Unfortunately, the game is not available in my country.
Regarding the VPN, I'm not actually sure if it is allowed since I haven't read the terms regarding this yet. I'll take a quick look later for my spare time or if anyone here who can confirm that.
