Unfortunately I can't reach this site without a vpn though I can't decide to make a bet yet. I don't know if your site has been blocked by my internet service provider or not but actually vpn is not one I would use to reach any gambling site.
You cannot use a VPN to register at any casino, nor can you use TOR to do so. I highly recommend you to avoid VPN when you can't access country blocked sites because you will be at risk later. Usually the casino TOS has information about this, so do it carefully and read the rules.
Do you have referral program?
