The sum procedure as every year
(Published on 5. June 2026, 09:20 by Lithium-Ion)
Normal Sudoku rules apply. Box borders divide the blue line into segments with the same sum. Cells that are equidistant from the central cell of a purple Zipper line (marked by the circle) must sum to the digit in the circle. A pink Renban line contains a set of non-repeating consecutive digits in any order. Adjacent cells along a green German whisper line contain digits that differ by at least 5. The sum of all digits that belong to one constraint type (e.g. all digits on Renban lines) is the same for each constraint types and must be deduced by the solver.

Solution code: The digits in row 8, read from left to right.

This took me a good while, but was very enjoyable. Forgot about the equality rule, but even after I remembered it I had to go through quite a bit of digging to get it solved.
Very nicely done puzzle, regardless.

This was so satisfying to solve! I had to pull out the pen and paper to get my numbers straight but once it clicked it went so smoothly

Loved this! I struggled with the break-in for a long time, but when I finally found the right thread to pull on it was a very satisfying unravelling!

well, i definitely broke something here. fortunately, self-repair is a feature of this model.
fairly easy, once you wrap your head around blue = pink = purple = green
