Neighbour Loop
I and the creator the_cogito came up with this puzzle long time ago. Hope you enjoy it.
Rules:
Normal Sudoku rules apply.
Draw a single closed loop that travels orthogonally through the center of some cells. The loop may not touch itself orthogonally, but may touch itself diagonally. Adjacent digits along the loop must differ by at least 5.
Digits may not repeat in cages. A number in the top left corner of a cage indicates the total sum of cells that the loop passes through within cages orthogonally adjacent to it.
A digit in a circle indicates the total number of cells that the loop passes through within cages orthogonally adjacent to the circle's respective cage.
