Shady Miracles

(Published on 7. April 2026, 19:20 by Pulsar)

This is a variation on a previous puzzle. Enjoy!

Rules:

Normal sudoku rules apply.

Disjoint groups: each relative box position consists of a set of the digits 1-9 (positions in a box are read from left to right and top to bottom).

Shade nine cells in the grid such that there is one shaded cell in each row, column, and box. The digit in each shaded cell is equal to its position in its box.

The first digit in each row indicates the position of the shaded cell in that row, and the first digit in each column indicates the position of the shaded cell in that column.

Digits separated by an 'X' sum to 10.

I really liked this puzzle, there’s plenty of beautiful logic at the beginning to get the second and subsequent digits. I think the difficulty is average.

Lovely puzzle! Such a simple ruleset for a puzzle with so many fun deductions :) I particularly love the interplay between the shading and the perimeter
