If you've got more hours on your hands today than you know what to do with, Evolution is probably exactly what you need. Unlike some of our other Time Wasters, it plays at a slow place - you won't need to have good aim or mad clicking skills - just some patience and the will to raise bugs.

The basic premise is this: you are a bug owner (the insect kind), and you raise bugs for a living. As such, you spend your days caring for your bugs' health and happiness, providing them food, and getting them ready to breed. As you breed different types of bugs with each other, you can spawn new types that are stronger, better, and faster. The goal of the game is to produce the "ultimate bug" which is at the very top of a relatively large evolutionary ladder.

In order to finance your bug raising enterprise, you can put a price on your bugs and sell them, or race/fight them against other bugs for prize money. As you make more money you can buy better food, "growth enhancers," and toys to keep your bugs happy. The trick is, that if you have too many bugs at once, they will die from unhappiness - so you have to keep the bugs you want to breed and get rid of the ones you don't want around.

Ultimately, Evolution is a nice way to waste your time - especially if you like raising things. And bugs.
