The Android Market has several successful games to offer. Although you won’t find any of my Android devices to have many games installed on them. I am just not a huge gamer when it comes to my mobile devices. On occasion I have installed games like Need for Speed: Shift, Restaurant Story, WordFeud and a few other games, but mostly for the purpose of relaxing or taking my mind off something.
A few days ago, I came across Air Control by Four Pixels. The game comes in a Lite (FREE) and Paid versions. I started off with the lite version and in a matter of an hour after playing it, got addicted to it. The objective of the game is simple! Try to land as many planes as you can without crashing them into each other. The more number of planes you successfully land the higher the ranking and status you get. The lite version only offers one airfield map, but the paid version (~2.00CDN) comes with two extra maps.
Definitely a game worth investing in. It is one of those games which you can play for hours and allows you to concentrate and learn to juggle mission critical priorities! 
Below are a few screenshots which I snagged from the games Market profile.
Enjoy!
