I dont know why there is no thread for this great game yet.
It's a tower defense game where you build towers to kill monsters. There are already some other games but they have predefined paths, here monsters want to go from A to B, and the great thing is that you can build your own "maze" as to say, to form their paths and make it harder for them to make it through.
The game has great graphics, cool features and it's just fun to play.
There is a free version available in the market and a recently released full version. The full version cost $2,99.
