Love shooting pool, but don't have a billiards parlor closer than the wrong side of town? Or a shoebox-size apartment with no room for a billiards table? Got an iPhone?
Load it up with Sauce Digital's Killer Pool, a state-of-the-art billiards simulator that fits in the palm of your hand. Its variety of games includes US and UK 8 ball, 9 Ball, Killer, and "OctoKiller," which is played on a unique eight-sided table. The game utilizes the iPhone's multi-touch capabilities for not only hitting the ball (which can be done by positioning the cue and finger-swiping it, or using the game's power meter), but also changing the orientation of the table. The game includes multiplayer mode, realistic sounds, and options to hit spin shots or swerve.
