It would be nice to see pool on a gambling site, but as you say, this is different in real life and the digital version of this game can be cheated, i think this is why we don't see it on the casinos. Maybe it would be nice to be able to bet on the pool tournaments, and i don't doubt some casinos already offer it.

And a game that i would love to see on a casino is backgammon. I have see in the past some projects trying to create this but non of them was a success. And i don't know why because this game is based on luck (and a bit of skill).
