It is virtually impossible to predict which game will be a success in the casino as it is being invented.  As I've written in my column numerous times, predicting which game will fail is much easier.  Frequently inventors will look at past games and try to replicate what appears to be a formula for success for that game.  But I have longed believed that if you look at successful casino games you will see a progression and not just a replication of success.  To put it another way, I think that if Three Card Poker were invented today and put up against the other games that are out there, it would not have done nearly as well as it did.  In similar fashion, if Ultimate Texas Hold'em had been created in the mid 1990's, I don't think any of us would have ever heard of it.
