AppAdvice has teamed up with S Games in order to offer you a chance to win one of five promo codes for Cocky Roach ($0.99) for iPhone and iPod touch.

Some insects are useful in the role of sustaining our environment, and these particular bugs may even seem slightly adorable, but it crosses a line when they crawl over our iDevices.

As the multi-legged critters scurry on the glass surface, use a single finger to squash them. Unfortunately, the glass is sensitive, so it cracks if you hit it directly. Therefore, try not to miss your targets, because too many fractures and the glass will break entirely.

At first, the task seems reasonably easy, only involving predictable beetle-like bugs. However, things become quite intense as you progress to later levels.

The first problem is variety. You’ll encounter winged bugs that move in quick, random direction hops, large spider-like bugs that crack the glass as they walk, and much more. The second issue is expansion. Normally, a positive thing in video games, hearts cause nothing but grief by offering a means for the bugs to multiply. Also, tapping a heart breaks the glass, so don’t do that.

Cocky Roach features 40 levels for you to conquer, and is compatible with iPhone 3GS, iPhone 4, iPhone 4S, 32GB and 64GB third generation iPod touch, fourth generation iPod touch and newer running iOS 4.0 or later.
