check this 008

Not sure what happened but on my 3rd try, I shot the ball and while it was spinning under the pipes, B was coming down the stairs and the side fell over onto the win. It didn't do that on the first 2 tries nor the 4th???

Thank you gmarcpro!
Hmm, may be I'll fix it.

Well I appreciate such a level but wanted to know the mechanism behind the win ...Cause it just happened like that

@HackedUp
The fantastic work mordor from vince gave me an inspiration.

Spoiler: Mechanism inside !
