If any platform has restriction on IP addresses, and you can not access it normally, let's move on to other sites. Don't try to use VPN and get problems later, it does not make sense.
Spinly has geo-restrictions, which means they do not accept players from some specific regions. If players use a VPN and later it appears that they are from the restricted region, the casino may ban their account and seize the funds. If a casino forbids VPN usage, players should not use a VPN at all. As for Spinly, they allow users to use a VPN to access the website.
However, it is not allowed to play if you are from the restricted region. Since it is a KYC platform, they might trigger KYC request if they detect anything suspicious. All the function will work as usual except for Goblet if players use a VPN to access Spinly.
