Angry Birds is one of the best games available for iPhone, iPad, Android devices and also for online browsers. Now Angry Birds is available as an offline game and can be played in Chrome browser without internet connection. You just need to install it once via Chrome browser and after that it can be played in offline mode.
There are two version available for Angry Bird (offline mode), i.e. SD version and HD version, HD version of the game require too much of bandwidth to download the game, although in my view SD version is not bad at all to play the game. I myself downloaded the SD version, and the graphics are good enough.
