Giraffe Hunt 2
(Eingestellt am 24. Oktober 2024, 22:08 Uhr von ralphwaldo1)
Normal Sudoku rules apply.
Anti-Giraffe: Cells (1,4) apart cannot be the same.
Kropki dots: black dots join digits that are in a 1:2 ratio; white dots join digits differing by 1.
Thermo: digits on the grey line increase from bulb to tip.
Killer Cage: digits in the black cage sum to the small number in the top-left of the cage.
Clone Cages: the blue cages contain the same pair of digits.
Thanks to gdc for setting the diagram so SudokuPad understands the anti-giraffe rule!
N.B. "Giraffe" is the name given in fairy chess problems to the (1,4)‑counterpart to the knight, as can be seen in the bonus chess problem with both knights replaced by Giraffes. (e.g. white Giraffe could play from e8 to f4).
Helpmate in 3 (Black helps White to give mate after BW BW BW)
Knights replaced by Giraffes.

This was fun, once you get the hang of it. Thanks, @ ralphwaldo1:). Will now try out the first one.

I have an anti-giraffe rule in my home: No giraffes allowed. I've never been bitten by a giraffe, so it's surprisingly effective.
In this sudoku, the anti-giraffe rule is also surprisingly effective. Great puzzle!

I was struggling for a long time but there came a point from where it started to roll and the puzzle kinda solved itself. It was so surprising and satisfying. Thanks!

I'm legitimately so pleased that the phrase "by giraffe logic" has entered the sudoku lexicon.

Fantastic follow-up to the original giraffe hunt. Silky smooth finish and nice presentation of "the idea".
