11croco gambling site is legal in a small number of countries, this opportunity is only available in countries where gambling is legal.
It's not necessarily because gambling is not legal for such countries. For instance, gambling is completely legal in my place, yet, I'm still restricted from playing. Perhaps, it has to do with the type of license 11croco has and their risk appetite.
I entered their link and it doesn't work, I was interested enough to participate in this gambling platform of theirs but it was not possible at all, I tried a lot with VPN but it was not possible.
BTW, it's against their terms of service to bypass country restrictions using VPN. I would not recommend it unless you're prepared for the worst. But you could probably find other casinos that allows your place. Games for the most part are more or less the same with a lot of platforms as well.
