No River Hold-Em is a patented game that is being sold to casinos like the pit carnival games, Caribbean Stud, etc.
The company is also trying to sell Royal Hold-Em, played only with 10's and higher cards.
I had a demostration of both 6 months ago.
Casinos pay so much per day to spread them.
Treasure Island tries No River for awhile.
IMO they won't go as the cost is more than poker rooms can absord.
There are several other companies trying with other variations of Hold-EM.
