Ratio lines - Dynamic fog
(Eingestellt am 31. Juli 2026, 05:56 Uhr von Killer Joe)
Hello.
Normal Sudoku rules apply.
On each line, the sum of either the odd digits or the even digits is exactly half or double the sum of the other parity.
Additionally, all end cells of any line contain digits of the same parity (all odd or all even).
Digits separated by a white dot are consecutive.
Entering correct digits may lift fog somewhere in the grid. No guessing is required.
Have fun.
Lösungscode: Row 9, first 6 digits.

This was really fun and interesting. Quite a variety of logic that was required along the way so it took some time, but never felt overwhelming.

Very nice puzzle, great fun! More of a 2-star for me but I’m used to parity sum puzzles. May I recommend you update the wording about line end parities (something like “on each line, the digits on every end are of the same parity i.e. all odd or all even”)? I initially interpreted it as a global rule where the ends of all lines in the puzzle are of the same parity. It broke pretty quickly so I realised not too far in but it might cause confusion for others too.
