Slots that are available to your country might not be available to your neighbouring country or any other country in Europe. There isnt any problem on this matter, if you want to try few slots for the sake of playing for fun then try to use India instead. You might risk your account if you try to bypass those slots using VPN
Another thing, it is better to be safe. So if you are trying to use VPN to check on few slots it is better to log out of your account
Thanks for an advice. I'd better not use VPN with roobet, there are plenty of slots still to play. The reason why I tried to check all the slots is the new contest by Hhampuz. I'd better not risk loosing my account by some glitch or gambling site protection mechanism, just to be able to try to win some spare bucks.
