The goal is the same as puzzle 52: Multiply the value in register A (middle column) by 5, and store the result in register B (left column). The twist is that red marbles are only allowed to modify register A, and blue marbles are only allowed to modify register B. You must also start with pulling the red lever. You are allowed to use as many parts as you would like, just like the real puzzle.
Initial board state: jstumble
My solution: jstumble
My solution is also a valid solution of puzzle 52, and I wonder if I’m the only one who was so zoomed in on the problem that I solved it in this way.
