Does anyone know of any Websites, Casinos, or Books that offer blackjack tournaments that US players can
participate in?

I used to play in multiplayer tourneys at Betonline until the software company they were using ( 21GNET ) closed up shop.

It was pretty fun and I used to pad my bankroll with it. I tried google and it seems that a lot of places that offered it were also using 21GNET so they are no longer active.

Just wondering if anyone's got some insight on this.
