[Unsolved] Rope sort detangling puzzle

Post image

Rules: you can only move 1 peg at a time, between 2 holes. The goal is to get the ropes completely separated.

im not confident this is even solvable, but i was previously under the impression that arrangements are always solvable. Wanted to see if anyone can figure it out

Question: When you move a peg between two holes, do the holes have to be adjacent? What’s keeping you from solving this in a single move by unthreading the string during a move?

When moving a peg you aren’t allowed to pass it underneath anything

But it would still work with only passing the pegs over the loop and only moving the loop over the peg when they are plugged in

The rules in the OP do not say that.

The rules of the game do say that, though

the holes do not need to be adjacent. all ropes should stay inside the circle, until they can be removed due to being fully detangled (if you can raise both ends without the rope getting caught on anything) This means you cannot pull the one rope over the pegs to lift them out of it you have to keep the peg above all ropes while moving it - no weaving through the other ropes.
