The Halls of Moria

(Published on 3. August 2026, 21:19 by vitray)

Normal sudoku rules apply: place the digits 1 to 9 in every row, column, and 3x3 box.

Dynamic fog: The grid is covered in fog. Certain digits reveal parts of the grid when placed correctly; other correct digits may not clear any fog, including in their own cell. No guessing is ever required.

Anti-king: Cells that touch diagonally may not contain the same digit.

Killer: Digits in a cage sum to the small clue in the cage's top-left corner. Digits may not repeat within a cage.

Kropki: Digits separated by a white dot are consecutive. Not all dots are given.

Speak, friend, and enter.

Straightforward solve once I overcame my confusion when fog didn’t clear when entering correct number. Missed that detail when scanning rules.
