Moonlights gives you World of Goo-like building tools, a simple star-speckled background, and soothing music. Then it asks you to build a tower to the moon. With several different kinds of building surfaces, an accessible level editor, and a meditative tone, this is one of the most laid-back construction games around.

How hard could building a bridge be? In a game where you have to retrieve an elephant from a distant island, the answer may surprise you. Cargo Bridge asks you to engineer a sturdy path for your movers as they transport crates, safes, and yes, elephants.

If The Incredible Machine met the classic board game Mouse Trap, TubeTwist would be the result. Arrange tubes, accelerators and other contraptions to manipulate the path of the Macroton (a colored marble-like object) from the Injector Tube (the start) to the Reactor Tube (the finish). It's that simple!

How cute can you take it? If your answer is merely "pretty darn cute", that won't be enough. Even your cursor becomes pudgy and extra cuddly as you set out to help the little Euwins return home. Build bridges across 70 levels worth of waterways in Bridgecraft!
