In the past couple months most realtime gaming online casinos no longer accept players from the US. The software is a vegas style gaming slots and video poker machines similar to what you would find in a land based casino. They also have a large selection of table games not found at other online casinos. The one thing that is really nice about the realtime gaming software is the penny machines. They have a large selection of games which you can play for a penny including keno.
The software payouts overall 97%, table games a highly popular by many players as the selection and style are familiar. Video poker and keno in these have always been one of the better games but slot machines have been improving over the years. I suggest trying Cool Cat or Club player to start out at.
