if the pipes are cut from a Spanning Tree connecting all the hexagons (like the one you witness once you have solved), then yes, for those give pipe pieces, there should be only one solution.
- jjnoakes 4y agoIs this true? I can almost imagine one puzzle that can create two different spanning trees. Maybe I ought to draw it up to verify. Spanning trees may be required but not sufficient for a unique solution.
- emadehsan 4y agoYou are right. It is possible that branches (pipes) cut from one Spanning Tree might be re-arrangeable into a different Spanning Tree.
