very cool concept, unfortunately I feel like complete idiot trying to solve the circle puzzles. I saw a lot of people making this same complaint as well as others saying they understand the underlying mechanics, something about a "3 brick algorithm" however nobody has actually explained how to solve them. I'd love for you (whoever is reading this) to actually explain how to solve these puzzles or what they're actually known as since searching for 3 brick algorithm just gives rubix cubes results.
