Angry Birds Star Wars

These achievements requires that you play the game a cumulative total of 30 hours (consecutive 30 hours not required). After earning all other achievements, you will likely need to grind somewhere between 15 and 25 hours, depending on your Angry Birds skill and use of video guides. 

You can disable your screen timeout (Settings>Lockscreen>Screen Timeout>Never) and leave the game running unattended while in a level for long periods of time with the phone plugged in. Make sure when you are done to complete the level by passing or failing to save your time. NOTE: This trick is not possible on all devices (screen timeout will be limited to 5 minutes). For those of you that cannot disable your screen timeout, you will need to grind this the old-fashioned way. Load up a level and let it sit while you do something else, making sure to tap the screen periodically before your timeout limit is reached. You could also play the game legitimately, but with such a limited amount of levels, this could be quite boring. Just be sure to complete or fail the level when you are done grinding for the time being in order to save your accumulated time. The achievements will not unlock until you complete a level.

For these three achievements you need to "play" the game for a total of 30 hours. This is actually a little ridiculous considering there are only 80 levels in the game. Luckily, the game counts time, even when the game is running unattended on your computer. First, make sure you computer is set to NOT hibernate, go to sleep, or bring up any type of screensaver. Then load up any level and just let it sit there. Personally, I think it is easiest just to set this up while you sleep (make sure tablet is charging if you are using one). Each morning, when you come back to your device, make sure to complete the level (either pass or fail) to save your progress. The achievements will also NOT unlock until your finish your current level (either pass or fail). After just a few nights, depending on how long you sleep, you will have these achievements.
