Rules
In detail.
- The U and A in the dial must swap with the other letters in the dial first.
- Each edge must replace other letters with a prev/next letter in the alphabet.
- The order of replacement of the edges is S, then D, then M.
- Each edge of the pyramid must replace one or both adjacent letters of the dial first.
- If an adjacent letter of the dial cannot be replaced (because it has already been switched) then an edge of the pyramid must replace an adjacent edge of the pyramid.
In synopsis.
- Insides of dial swap.
- Edges replace inside (dial).
- Edges replace outside (pyramid).
