I LOVE THIS!
If you folks like that, you’ll absolutely love ‘Armadillo Run’.
Damn you, Gorsnak!
Embarassingly simple solution to the Junkyard
Ok , help a dumb guy out, how do you do big ball?
YMMV
Handling has me stumped…I can get the cargo to the goal, but I can’t figure out a way to not drag it out, or fall over once it’s there…
Awesome.
I was trying some sort of two vehicular thing , with one climbing over the other and pushing the ball out the way from the backside, mostly ended up looking like two rabid dogs humping.
And discovering you can actually move the red load around yourself kind of helps as well
What about Tube, Up the Stairs, and Four Balls? Once I figure out how to defeat those three, I can put this damn thing down. 
I -just- beat 4 balls now.I built a ramp with a stick, and built a car on top of it with a multi segmented water ‘rope’, if you will. Then I attached a triangle to the end of the rope, and used the cars weight to tug the triangle up the ramp. The trick was to make the rope long enough to let the balls drop before the triangle started moving. Other methods on the solved page were escalators, conveyor systems from the top, bottom, and top and bottom
The tube sucks. You gotta get a CW turning wheel jammed up against the right wall and a CCW turning wheel jammed up against the left wall. Then they will just climb right up the tube. The tricky part is getting a framework so the weight of the structure forces the wheels against the walls enough for it to climb.
Ooh, that’s really clever, thanks! I tried to build a conveyor belt with a catapult on the end, but the last ball always slipped under that gap in the beginning.
I have wasted so much time on this game today!
I spent ages just trying to do Down Under.
Naw, you don’t need to use the weight of the structure to push the wheels out - you have available power sources you can use to push the wheels against the walls:
And here’s a nice speedy Tube 
Here’re some of my favorites:
For Four Balls I did this, give it enough time, the pulling is sloooooooooow.
Just got 4 balls:
And boy is my wife happy!
Also:
Mine, like all mine, was sad and pathetic. I made a base layer of unmoving balls and put a platform on it. I laid a wood chain on top of that, and then built a caterpillar of orange wheels with wood connectors. Finally, I attached a “leash” to the caterpillar’s head, made of water pipes, that connected to the back of the chain. The caterpillar crawled up and across the pit, at which point the leash drew tight and pulled the end of the wooden chain with it, capturing all the red balls that had rolled onto the wooden chain. The caterpillar continued off the edge, hanging itself and dragging the improvised net behind it into the target area. It was nowhere near as cool as the other solutions people saved.
Check out the forums there for a thread called “overly complex solutions”. There’s not that many entries, but some of them are good-god weird. My favorite is the stomping elephant creature.
