Nicely done, DOINKSTER. I've added your solution to the OP and I've also added another challenge.

Well...these are sure very hard...

But if collab is open then:

I started Pick and Put in 9 pcs : http://www.sparkworkz.com/fc2/?designId=398501

This is just a main idea, I can make it work nice

Great job, Cruiser! I see you got the 8pc I tried for that very design, but never got enough momentum up the ramp, so I settled with a 9pc. I'll add your solution to the OP.

Ok guys, Here is what I have for COME CLEAN. I cant get the goal piece to go over the little hump at the top.

Awesome job there!

OK, for the next challenge, I've gone old-skool and chose the first ever user-made level, which was made by kennetha on 2009-12-11. The best efficiency was 2pc. I went and did it 1pc brown, and that's today's challenge.

EDIT: Another challenge (Hold up a minute) added
