For the life of me I have never had the opportunity to play Angry Birds, until now. The Google Chrome version is now available to you on your PC and from what I can tell (from my testing) you do not need the Google Chrome Browser to play Angry Birds. Simply type into your web browser, http://chrome.angrybirds.com . It worked for me in Internet Explorer, Firefox and of course Google Chrome.
What is Angry Birds? I can tell you this, it is very popular with millions of people. I checked Wikipedia and here is what they had on Angry Birds:
In the game, players use a slingshot to launch birds at pigs stationed on or within various structures, with the intent of destroying all the pigs on the playfield. As players advance through the game, new birds appear, some with special abilities that can be activated by the player. Rovio Mobile has supported Angry Birds with numerous free updates that add additional game content, and the company has even released stand-alone holiday and promotional versions of the game.
