Game developer X-Com has also released Barry Woods to the App Store for free. It is puzzle a game where your goal is to knock down all the kegels before taking down the "king". The physics-driven game is based on the classic Swedish lawn game Kubb, and it is a lot like Angry Birds and Crush the Castle.

Endless Road from Chillingo Ltd is now free for a limited time. The driving game is a sleek looking endless runner where players must drive for their lives to avoid the crumbling road behind them. Like most endless runner games, players must avoid various obstacles while collecting coins, and power-ups. The coins can then be used in the "garage" to buy upgrades and new cars.

Endless Road avoids being another run of the mill endless runners thanks to its isometric landscapes, clean looking graphics, and fun soundtrack. The game also features leader board support, 48 unique challenges, and the ability to compete with Facebook friends in weekly tournaments. There are also plenty of power-ups, weapons and maps to unlock to keep you busy.
