Though I'm frankly bored of casual-looking, free-to-play games for my tablet, I must admit that FlyCraft Herbie: Crazy Machines seemed both intriguing enough to try out and, well, good enough to actually recommend. Developers nlogn have created a physics-based action game that transcends its cute graphics and enters brutal, satisfying, hardcore territory. Just using the two rockets strapped to each of your demented flying(-ish) contraptions you get to attempt to navigate cartoony mazes, when performing a simple 90 degrees turn is a task that will take time to master.

Getting even simple things done though is a reward in itself.

FlyCraft Herbie: Crazy Machines is free to download for iOS, Android and Blackberry. It comes with relatively unobtrusive in-app purchases.
