If you want to simulate going to a club that's full of women in revealing dresses to play some snooker, then Snooker Club is for you! It combines great graphics, both 2D and 3D, with a realistic and satisfying snooker experience at the low price of free.
For those of you who don't know, snooker is a game very similar to pool, though not nearly as popular or widespread (at least in the US). The balls are colored instead of numbered, and you must hit a red ball before you can hit any other color, until the red balls are all gone. Definitely read the rules if you are unfamiliar. Other than the rules, the game is played quite like pool.
The app seems to be a pretty accurate depiction of the game in terms of physics. The controls are easy to learn, and you'll be pocketing those balls in no time. Unfortunately for you, the computer opponent AI is ruthless. I once sat idly by and watched as it accrued more than 50 points without making any mistakes, unable to do anything about it. The game is unforgiving, which is unfortunate, because it takes some time to figure out how to aim the ball properly. This makes the early game rather annoying.
Luckily, you can play with a friend by passing the iPhone/iPad back and forth, which is much more like a real game experience, as you are both likely to be terrible at first. There is no online multiplayer yet, but it is supposedly on the way. The game also offers Game Center achievements and leader boards, which should keep things interesting.
