Lately, I've been playing this game a lot. Since I'm addicted to real billiards, and I'm too lazy to go outside, I've installed this great game.

It has a lot of game types (Card Game, 8-Ball,9-ball,Rotate,3-ball, etc) and rooms. The amazing idea behind this apart from the online playing is making it a RPG. 

You have online credits (chalk) and you can buy skills, effects, characters, skins, even some add-ons to your own game blog.

Check it out and see how they turned a simple game into a addictive RPG:
