Back in May, Rovio announced Rovio Account, a feature that would allow players to sync their game progress in Rovio-made games across platforms so that every device the player owned could pick up where the player left off. Rovio Account was available globally for Rovio's The Croods game, and only in Poland and Finland for the original Angry Birds game; today's announcement unveils global access for Angry Birds too.
Rovio Account is a free feature and requires the user to create and set up an account. Once done, the user can synchronize their progress across all of their devices, whether Android, iOS, or otherwise. This means no more of having to painstakingly repeat levels on each device simply to have each device stay on the same page:
