Our strategy for Angry Birds Star Wars Tatooine level 1-8 is to launch Obi-Wan low, towards the first wooden pile of blocks. Initiate the Force upon impact. The blocks should be sent flying high to the right, detonating both tnt boxes.
Note: In this video, Luke is not yet equipped with his lightsaber. Obi-Wan Kenobi will give him one on Level 1-9.
