Inspired by Earth Wurm—a recent collab with yttrio.


Normal Sudoku rules apply.

Draw a one-cell-wide loop of orthogonally-connected cells. The loop cannot touch itself orthogonally, but may touch itself diagonally. Additionally:

  • All squares are on the loop.
  • A digit in a square gives the number of loop cells seen in all horizontal/vertical directions combined, including the cell with the square. Non-loop cells block the vision.
  • The loop acts as a Region Sum Line. The digits on the loop have the same sum in each 3x3 box the loop passes through. If the loop visits a box multiple times, the sum is counted separately for each loop segment.

Solve online:

Lösungscode: The digits in Row 7 followed by the number of loop cells in Row 7 (10 digits total)

Superb. Though I did think it was closer to 4 star in difficulty.

A very worthy sequel to Earth Wurm indeed!

Sightlines and loops are such a juicy pairing, wonderful puzzle!

Beautiful how the logic of the loop and the square digits work together to unravel this puzzle. Challenging but never stuck, great balance all the way through the mid-solve. Thanks for setting :]
