13 Sequence
(Published on 8. April 2024, 12:00 by kierownik)
- Normal 9x9 sudoku rules apply: In every row, column and in every 3x3 box the digits from 1 to 9 have to appear atleast once with no repeats.
- Non-consecutive: Cells that are orthogonally adjacent cannot contain consecutive digits.
- Anti-king: Cells seperated by a king’s move in chess cannot have the same digit.
- Anti-knight: Cells seperated by a knight’s move in chess cannot have the same digit.
- Killer cages: Digits in cages must sum to the number in the top-left corner(if givin) of the cage and cannot repeat.
- Sequence line: Sequence lines contain digits in order with a constant difference. E.g. 1-2-3, 2-5-8 or even 3-3-3. A sequence line always goes in one direction, so it goes up, down or stays the same

First time I've seen this constraint. It's interesting how it forces things in some of these lines.
Turned into a partial colouring puzzle for a bit

Interesting way to make one of these. Are you aware that any line that doesn't touch row 3 and isn't in the 12 cage is actually not necessary for a unique solve?
The 12 cage line must have 4 in the middle cell of the line.
Non-consecutive forces all 5-cell lines to be 1-3-5-7-9 due to having a vertical segment.
The 4-cell lines have middle cells that see all of a 5-cell line, or all but an end cell of a 5-cell line, and therefore must be 2-4-6-8.
The 4 in R6C1 gives the order of the line in R4C2, and then the other constraints and sudoku finish the grid.
I'm not trying to influence anything with this, just sharing my experience. It was a fun way to spend ten minutes.
Kierownik, I know some lines do not need to Be there but I want everyone to enjoy the puzzle, including me :)
