Running on Wires, by pmays123

• Divide the grid into 6 six-cell orthogonally connected regions, and place the digits 1-6 once in each row, column, and region.
• Outside the grid, clues sit between rows/columns and indicate the grid line that separates these rows/columns (e.g. the 3 between c1 and c2 refers to the grid line between c1 and c2). Each clue counts how many continuous stretches of region border appear along its grid line.
• Region borders divide the grey line into segments. None of these segments may have the same sum.
• The arrow points to the lesser of the two digits it sits between.

Here is an example image of how the outside clues work:

I hope you enjoy the puzzle! I'm planning on experimenting with this type of outside clue more in the future. Feedback is greatly appreciated. Good luck, and have a great day! :)
