There is billard game: # Implements carom billiards (eg. straight rail, balk line and cushion games) and pool games (e.g. eightball and nineball). # Sports decent graphics if you have a GPU that's well supported in Linux. This kind of narrows your options down, so if you're having trouble running the game with your GPU there's a plain and functional toon shaded codepath that you can try (alas, without the fancy shading). # Has decent physics and totally configurable on top. You can change a whole bunch of parameters, most of which you probably don't know the meaning of. # Features undoing and setting up of shots. What more do you need to practice? # Has a neat GUI implemented using HTTP. Just connect with your favorite browser to http://127.0.0.1:29176 while the game is running. It's got all the features you're used to through years of web browsing and it won't be in your way when you don't need it.
