But still, it's better to know if VPN use is really allowed.
According to their terms of use, it's not allowed to use VPN and they may block your account, if you do so.
9.3. Fraudulent activity
Once coins.game noticed a fraudulent, unlawful, dishonest or improper activity (including using the VPN, proxy or similar service that masks or manipulates the identification of your real location, or making bets, wagers or poker play through a third party or on behalf of a third party) on the Website, we are eligible to block user’s Account with forfeiting of all Account balances without prior notification. In such cases, coins.game reserves the right to report fraudulent activity to existing regulatory and law enforcement authorities including but not limited to banks, credit card companies and/or any person or entity that has the legal right to such information, and/or taking legal action against such user.
This means that there is contradiction between the explanation from the support and the written term, this kind of thing can be bad for the player because even if the support tell player that VPN is allowed but once there is writtern term then it will be easy for the casino to use the written term to act against player.
Once it is happened, players will have no power although the players can show the proof that the support allow players to use VPN.
Of course a good casino may try to investigate the case and if the support is the one who made the mistake then the players should not be the one to take the effect (blocked/banned).
However, when it comes to bad casino, high possibility that the casino will not care about it although the support is the one to be blamed due to wrong information.
