The game doesn't require installation and starts a game right away after being launched. This can be a bit confusing because apparently there is no game menu or any way to change configuration settings. The trick is pressing the Esc key: you'll open the menu and will have access to the game's settings, where you'll be able to choose the type of pool (8-ball, 9-ball, carom or snooker), game mode (single game, tournament or championship), players (either human or computer-controlled) or decide if you want to play a game over the Internet.
FooBillard shows highly realistic physics in the ball's movements and in their reactions when hitting other balls or against the pool table. Despite the game's minimalist design (you only see the table against a dark background) the graphics are certainly impressive. Pity we can't say the same about the soundtrack, which is limited to some noises when the ball hits against something.
Play pool in your computer and enjoy the realistic graphics and physics of FooBillard.
