If you are a fan of casual PC games then you know Peggle, the addictive action-puzzle game from Popcap Games. The title combines a colorful art style with gameplay that has you trying to get rid of pegs in each level via firing balls and hoping your shot combined with gravity and bounce-backs from other special ricochet pegs. The game was released in early 2007 and has since been downloaded 20 million times. Peggle got an extra boost thanks to Valve, who included a special version of the game, Peggle Extreme, with every version of their game collection The Orange Box in the fall of 2007, complete with art and sounds from the games in the collection.

Now Popcap has finally released the long awaited next game in the series, Peggle Nights. This new game contains, among other things, 60 new Adventure levels and 60 new Challenge mode levels along with new power-ups, trophies and more. The full version of the game costs $19.99 but a free demo is available. The game will be available for sale on other sites, including Valve's Steam, next month. There's no word on if there will be a special Left 4 Dead version of Peggle Nights released.
