Through the Comet’s Eye
(Published on 29. December 2025, 12:17 by Nurator)
This puzzle has been set for the Secret Santa challenge on the CtC discord and is approved by the Santee to be published here :)
Rules:Normal Sudoku rules apply.
Star Battle: Each row, column, and box contains exactly two stars. Stars may not touch orthogonally or diagonally. Stars also contain digits and behave as normal Sudoku cells.
Habitable Zone: Any digit orthogonally adjacent to a star must differ from the star’s digit by at least 3.
Comets: Little-killer clues give the sum of star digits along the indicated diagonal (only star cells count).
Resonance: Identical digits may not be a knight’s move apart.
Solution code: First row (9 digits)

This is a very clever puzzle, which was easier than I made it due to sucking at anti knight scanning. :)

very nice puzzle. the sudokupad solution checker has a king's move restriction which should be removed
