"Octo Puzzle" Sudoku Variant
(Published on 17. January 2021, 04:39 by Garford)
Every row, column and (irregular) region needs to be filled with the numbers 1 to 9 without repeats.
Thermometer:
On the thermometer (regions 5 and 6) numbers increase strictly beginning from the bulb. The thermometer ends in the central cell of the grid.
Killer Cage:
In the killer cage (region 2 and 5) numbers do not repeat, and sum up to an odd number.
Arrow:
Numbers along the arrow (region 4 and 5) must sum to the two-digit number in the circled cells, read from left to right.
In-between-line
Numbers along a in-between-line (region 5 and 8) must all be in lower than the highest and higher than the lowest number on the grey circled ends of the line. One end is at the central cell of the grid.
Quadruple:
Numbers in white circles overlapping four cells must all appear within those cells.
* Kropki-Clues:
The grey circles (?) can obey any common Kropki rule, meaning the neighbouring cells may have any difference or any ratio. However, all four given Kropki clues behave exactly the same.

Solution code: The nine numbers of row 3 followed by the nine numbers of row 8 in order from left to right.

I love the way the logic bounces all around this grid. The clues might look unrelated at first but the way the logic moves between them is brilliant.
Excellent setting!
