How do you beat level 7 Inca on civi balls 2

first you go red into the second launcher. then let the biggest ball drop. then do the green intom the first launcher. then let the 2nd ball drop (should be swinnging.) then drop the last ball.! this should work. it helped me.!

drop red into the far right launcher
cut the left chain on the green (swings)
bounce the red off of the green.
drop big one onto the green (swings)
shoot into the goal!
