One non-character swap strategy for Angry Birds Star Wars II Rewards Chapter level BR-18 is to fling Han Solo down at a low arch so he comes back up and severs the top three ropes and continues into the far right rope securing the metal block. About halfway before entering the bubble fire his blaster at an angle down towards the bottom left structure. The collapsing structure should free the wood boulders and they should float up and finish off the level. The score in the video below is 105,720.
