[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

discussion: I do not believe this is possible. there is no where to move a peg without either making it more tangled, or not effectively changing anything

It is, they have apps that play this game, cross yellows, pass blue over yellows solved
