I solved this puzzle some time back. I don't remember how long it took me to figure this out, but it was time well spent. Very engaging...try it!
This is one of my favourite flash based games. Check out 3D Curve Ball! I have played it many times before and never passed level 4; but guess what; tried it just before adding this blog and got to Level 7. My score 21410. See if you can better it.
