If you really want to play, you can opt to find some alternatives to those games that you like. I don't really recommend using VPN as it could lead to being punished once caught. In addition, I think most casinos don't allow its usage so you'll just end up being banned.
With this alternative solution, it is still widely used when the game is not available, but it has to bear the risk and to be honest I've been this naughty using a VPN to be able to play Pragmatic play that I want, but using a VPN is no problem, as long as it's not too frequent and is still under $500 or under again I think it's pretty safe except for the big stakes I don't recommend it.
There is no other way this is already the rule then we have to find an alternative way which is VPN.
^ It is quite risky probably, I think the best thing to do if you are planning to use VPN is to read the TOS first and find how strict they are upon using VPN because there are most casinos that can detect players that who will use VPN and probably will have the result of compromising accounts. There are gambling casinos that use VPNs is allowed and while others did not.
However, this is probably a good option if you will ask the casino regarding the VPN and let them know about your purpose, but if they did not allow, just move on and find another one.
