This is THE MOST infuriating puzzle I have ever encountered in Diggy's Adventure. I had to walk away from the game several times before accomplishing this one. What makes it so frustrating is how the screen on my phone moves every time Diggy pulls a lever. Zooming out doesn't help, the screen still moves and the levers become so small I end up tapping the incorrect lever. ARRRGG!!!
Thank you to all those who posted here and help get me through this one.
