Xedni lines
(Eingestellt am 12. April 2025, 02:12 Uhr von ralphwaldo1)
The opposite of index lines, in which the digit in position d along a line always indexes the position of the digit d. On a Xedni line, that can never happen.
Thanks to gdc for aesthetic suggestions, programming and to ThePedallingPianist for testing.
Ongoing series
Sudoku: Place the digits 1-9 once each into every row, column and box.
Xedni lines: A line of length N contains the digits from 1 to N without repeats. If the nth cell on a line (with the diamond being the 1st cell) contains the digit d, then the dth cell may not contain the digit n.
Lösungscode: Row 9

Somehow I found the 6x6 trickier than this 9x9 which flowed quite nicely and wasn‘t all that difficult. Thanks for setting this beautiful remix.

Interesting idea for a rule. Once I wrapped head around it, found it quite easy except for one step in the middle. Good fun.

If any YouTube sudoku experts can read this, then stop whatever you are doing and let this puzzle be your next feature.
