No. You cannot access Betandplay for real money gambling from the US. Or more accurately, from an American IP address.
There are in fact many countries listed in the Betandplay Terms & Conditions, from which depositing and playing in real money is strictly restricted. To get around this you can try using a VPN to log in to Betandplay. However, keep in mind, again according to the T&Cs: “The casino cannot guarantee successful processing of withdrawals or refunds in the event that a player breaches this Restricted Countries policy.”
