Easy Peasy Sudoku Leftover (07) - Zipper Lines ++
(Published on 11. March 2026, 06:00 by Richard)
Making the Easy Peasy Advent Sudokus wasn't always easy for me, so I have a small pile of 11 leftovers. Some were too hard, others were equally hard, nice or interesting as the one in the Calendar.
Zipper Lines ++
Solve online in
Sudokupad.
But they are all too good to stay unused, so in the coming weeks there will be a leftover on Wednesday and Friday.
SVS will continue on March 27.
Apply classic sudoku rules.
The sums of each pair of digits coming out from the center (indicated by a diamond) of a Zipper plus line increases by one.
E.g.: if the single center cell contains an 8, the sums of the pairs go up to 9, 10, 11 etc. If the sum of the central pair of digits is 6, the sums of the next pairs go up to 7, 8, 9 etc.
Digits may be repeated on lines.
Solution code: Column 2

Pretty clear starting point, and then it slowly but surely unravels. I enjoyed figuring out the logic for Z++

Thank you very much for creating and sharing this beautiful puzzle. Though not easy peasy (well, at least for me).
