Xedni lines 6x6 #1
(Published on 12. April 2025, 02:12 by ralphwaldo1)
Xedni lines
Sudoku: Place the digits 1-6 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.
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.

Xedni lines are very interesting. I found this puzzle very easy. However, then I also tried your previous 9x9 Xedni puzzle and that took me way longer. I guess I don't truly understand these lines yet.. Fun puzzle, thank you
