If you own a Windows Phone, and lets face it, after the latest deals with the Nokia 530 we all should (personally my family are rocking Nokia 520's, Nokia 920's, and I'm rocking the monster Nokia 1520), you should all be chasing some quality games to play.
After making the odd game (Angry Birds Rio, Seasons, etc.) free, Rovio has just made the decision (likely in the lead up to releasing Angry Birds Transformers) to make EVERY existing Angry Birds game on Windows Phone FREE!
Direct links to the Windows Phone Store:
Angry Birds
Angry Birds Rio
Angry Birds Seasons
Angry Birds Space
Angry Birds Star Wars
Angry Birds Star Wars II
Angry Birds Go!
Angry Birds Epic
Bad Piggies
(I've uploaded a picture of the Angry Birds logo and not put a link in the main header - hoping this is OK, as there is multiple links. First time poster and all, hoping this is all OK!)
They do this on every platform. They add in stupid paid upgrades etc. They're not really free now, just freemium like everything else.
