When Temple Run hit the App Store in summer 2011, it didn't look like much -- no thanks to its pixelated, original PlayStation-level graphics and unremarkable visual design. But the old adage about not judging a book by its cover holds true with free iOS games, as well, as its genre-shifting 3D twist on the traditional side-scrolling runner made it an absolute sensation, racking up more than 170 million downloads in the time since. With new sequel Temple Run 2, Imangi Studios needn't worry about making a bad impression, thanks to dramatic visual improvements and welcomed gameplay enhancements.

A dark, moody atmosphere and a mysterious safe filled with complex puzzle-box curiosities lie at the heart of The Room, an enthralling puzzler that balances intrigue with challenge. Much like a set of Russian nesting dolls, cracking the outer shell of the massive iron box awaiting in the center of this grim abode only leads you deeper down the rabbit hole of mechanical conundrums to solve. Locked in single room and left with a peculiar note hinting at the powerful artifact tucked away within the huge safe, your task is to unravel the winding puzzle-filled path to this ancient device.

It's difficult being a delivery truck driver, particularly when the directions to your destination require a path that's not on any map, and the people you encounter along the way only seem interested in twisting you up in their own winding affairs. That's the case in the first act of Kentucky Route Zero, an offbeat and alluringly atmospheric five-part episodic adventure for Mac that finds its lead, Conway, out in search of a mystical highway.
