Yes, you can use a VPN to play at Hot.Bet casino. This gives you access to Hot.Bet from the US as well as a long list of other restricted territories.
Whether or not you should use a VPN, however, is up to you. On the positive side, even a free VPN service turned on to an IP where gambling is allowed will give you access to the full Hot.Bet offering. But in so doing, you will need to consider how you will fill in your registration form and verify your account for withdrawals, should the need arise.
