Find one colour and one direction that explain the entire route. On each hop, that colour swaps places with the dot in the next corner of the square. The other two dots stay put.
These snapshots are examples, not the answer to your current puzzle.
If the rule is red moves clockwise, compare these snapshots with the start above.
A single hop may fit several rules. Follow the same colour and direction across the next hops to test your idea. Tap a touching hexagon to move, or tap your previous hexagon to backtrack.
Six hops of one neighbour-swap rule turn the starting layout halfway around. Use that repeated shape as a check, then verify every hop: the endpoint alone does not prove the route.
