Bad Piggies Rise and Swine Level 2-10 Walkthrough

I built a 4 box contraption as follows. Top row: 2 suction cup wheels in the first and third square. 2nd row: 3 steel boxes, engine in front, glove in the middle facing down. 3rd row: steel box under glove with freckles.

Roll forward just till you hit the slanted part of the roof and trigger the glove. It’ll launch box with freckles right through the star and into the finish.
