Go bowling without leaving the house. Bowling PC is a cinematic-looking 3D bowling game and is exceedingly simple: Knock down the pins. You control the ball's placement by using the arrow keys, and then use other keys to determine when and where to throw it.
You can play against the computer, or against other people on your PC, and you get plenty of options, such as for which ball to use, whether to play rock music while bowling, the angle of the "camera" that tracks the ball and the game, and so on.
One nice touch: There are good sound effects that mimic the sound a bowling ball makes as it heads down the alley, and when it hits the pins.
Note: Note that when you install the software, it will also by default install the Ask toolbar and change your default search engine to Ask.com. If you don't want the toolbar or change in your search engine, uncheck the boxes during installation.
