Big Setup level 10-15 is very challenging, but relies entirely on the first shot. Launch Big Brother into the arm of the crane, causing the TNT to fall. The lower the TNT falls before detonating, the more likely to trigger a chain reaction. Keep trying until you manage that elusive one-bird clear. The score in the video below is 109,400.
If you have a different strategy feel free to leave a comment below; however, don't just post your score via the comments, as that's what the leaderboards are for.

AMslimfordy video provided the basic strategy. Found that if Big Brother cuts the rope rather than hitting the wood plank it produced a few more points. The bird needs to follow the tnt to the bottom plank for the best results.
Ok, but where should the rope be cut, relative to it’s anchor point?
@truckdriver I couldn’t figure out where exactly either, however I followed the video as closely as possible and kept at it untill I beat the score and avg! If you visit this level again all I can say is I wish for you the ‘L’ factor cause this is a frustrating level!! :)
Thanks, but it’ll be a while before I start going after averages again. Right now, I’m working my way through Seasons, then there’s Rio and Space.
Like @Kimmiecv said @TruckDriver I finnally got above average. Following video..you know the drill on these levels;) over and over and over again..
Gl :)
Ty Kimmiecv and wrw01 :)
Haha you are movin right along!if I helped in any way Im thrilled!And nice score :)
You’re right about the L-Factor, @kimmiecv! This is an easy but frustrating level. Scores vary greatly from how much of the wood is destroyed after all of the pigs are gone. I’ll happily settle for what I got and maybe try for higher later.
IKR @sweetp (cute handle!! :D) but you got yourself a great score!! Good for you!! And good luck on your continued quest through ABO!! :)
Thanks for the compliments @kimmiecv. Good luck to you in your bird flinging quests! :)
