The most popular game Angry Birds’ developer Rovio has announced the launch of a new feature called “Account” that allows users sync your game progress (game levels) across your devices – a most needed feature and quite useful when you have switching to a new device or reinstalling the game again. You no longer need to complete the same levels again on each device that you play a game.
Rovio Account is currently available in “The Croods” game globally, and in the classic Angry Birds game on iOS in Finland and Poland. They have promised to release this feature on other games and platforms in near future.
Moreover, users can use multiple Rovio Accounts on a device with different game level status, which is useful, especially if all family members share the same tablet to play the game. They can save their own game level separately and sync it with their other phones or vice versa.
For your information, years back I had posted an article titled “Backup and Transfer Angry Birds Game levels on Android”. If you are serious about your game Angry Birds, you may look into that also. (via)
