Halves and Halve Nots (Dynamic Fog Edition)
(Published on 28. September 2025, 22:45 by ViKingPrime)
PUZZLE:
RULES:
Normal
SUDOKU rules apply.
Values along an
ARROW sum to the value in its attached circle.
Place
HALVER cells into the grid so that there is exactly one Halver cell in each row, column and box; each Halver cell must contain a different digit and the value of a Halver cell is half the value of the contained digit.
In every row and column there is at least one pair of adjacent values in a
RATIO of 1:N, wherein 'N' is the row or column number. These values must represent whole numbers (e.g. in row 4, there must be a domino of values such as {1, 4} or {2, 8} but not {0.5, 2}).
The grid is partially covered in dynamic
FOG; placing a correct digit lifts fog from its cell and sometimes other cells.
Numbers outside of the grid are provided for tracking purposes only.
INTRODUCTION:
A big thank you to
Marty Sears for the encouragement in remastering this puzzle and to
Justin Vitanza and
gdc for testing. The inclusion of dynamic fog was a huge improvement over the original and helped take a lot of the pain points out of what was otherwise a really interesting constraint. I hope you agree.
Have fun!
...and if you're finding the break-in a challenge, ask yourself
where can the modified 1 exist in the grid?
Solution code: The digits along Row 8, left-to-right.

I like this version. Gives you a bit more direction for finding those big deductions.
