A free game for iphone
8 Ball Pool - Miniclip is one of those things that you probably don't want to get into unless you've got plenty of time on your hands. As with all pool- or snooker-based games it's extremely addictive and it really doesn't matter how talented you are with a cue in real life. Just be prepared for some initial humiliation as you get used to the game controls.
Play friends or take part in tournaments
8 Ball Pool - Miniclip allows you to sign in with Facebook so you can play with FB friends or you can sign in as a guest. The game will then match you with another player and away you go. It'll take a while to get used to playing the game but once there you'll be able to control the angle speed and spin of the cue ball with no problems. You earn 'coins' by winning games and you can buy more coins with your own real-life money if you wish or wait for your coins to increase hourly if you're unlucky enough to lose a game. You also get occasional spins of a wheel for a chance to win more coins.
Good fun game
All in all 8 Ball Pool - Miniclip is a fun game to play and will help pass the time if you're prepared to practice a little.
