Puzzle 20 - 18 parts


Optimising Menderbug’s solution by replacing 4 ramps with the 2 crossovers. I’m pretty sure this is the minimum piece count for this puzzle.



I came up with the same optimization.

I’ve been thinking quite heavily on this one and could not optimize it more. I agree it should be the minimum pieces solution


Geez - you guys beat mine into the ground, stomped on it, dug it up, and stomped on it some more. Way to go!


Nice! I really like what y’all did here; the optimization of counting on the bits to be in the right position is nifty, and the further optimization with crossovers makes it even cooler. Thanks for posting these!
