Unique Ratios
(Published on 7. October 2024, 21:34 by Burak Alver)
Place subsets of digits 1-9 into every row, every column, and every 2-by-2 box so that no digit is repeated in any row, column, or box.
Kropki Dots: Digits separated by white kropki dots are consecutive, and digits separated by black kropki dots have 1:2 ratio. All possible dots are given.
Killer Cages: Digits in a killer cage sum to the clue in the top left corner of the cage.
Unique Ratios: The ratios of adjacent cells are unique, e.g., if R1C1 is 1 and R1C2 is 3, then there cannot be any pair of adjacent cells that have 1:3 ratio anywhere else on the grid.

Solution code: All digits in all cells, from top to bottom, and left to right, i.e., R1C1-R1C2-R1C3-R1C4-R2C1-...-R4C4.
