Voices in the Fog
(Published yesterday, 22:40 by ul-Rhymm)
Sudoku: Each digit, 1-9, appears exactly once in each row, column, and 3x3 region.
Maximum: The digit in R4C5 is greater than all orthogonally adjacent digits.
Whispers: Cells connected by a green line have a difference of at least 5.
Negative constraint: All possible green lines are given. That is, any two cells that touch sides or corners and are not connected by a green line have a difference of less than 5.
Fog: Some cells are hidden by fog. Correctly placing a digit clears that cell’s fog. No guessing is required.
Solution code: Row 6, Left to Right.
