Same Sum Whisper Loop
(Published on 11. October 2025, 00:44 by yttrio)
Rules:
Normal Sudoku rules apply.
Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.
The loop acts as a German Whispers line (i.e., adjacent digits on the loop must have a difference of at least 5).
The loop must enter every cell of every cage.
The sum of all digits in any given cage is the same for every cage (that sum must be determined by the solver). Digits may repeat within a cage if allowed by other rules.
Solution code: Digits on the loop in row 5 (left to right) followed by digits on the loop in row 8 (left to right)

Really enjoyable, but it's a 108 minute solve for me. Thanks!

Awesome puzzle! Incredibly smooth, and would have been even smoother if I remembered the cage sum rule during the mid solve… loved it!

to do this comfortably, you need to understand the global and regional properties of german whisper loops.
1) the loop must be a subset of a CHECKERBOARD high/low pattern.
2) too many cells in a region run into the 4/6 problem

Not all that approachable to me. A harder 2* at least. Very cool ideas in it. Tough but rewarding. Another great loop addition thx.
