Anti-Ratio Astronomy
(Published on 15. October 2023, 06:43 by Scojo)
- Normal sudoku rules apply: Place the digits 1-9 once each in every row, column, and 3x3 box.
- Spiral Galaxy: Divide the grid into galaxies, which are orthogonally connected groups of cells that have 180 degree rotational symmetry about their centers, and do not overlap with other galaxies. All cells must be part of a galaxy. The center of every galaxy is marked by a red dot. Digits may not repeat within a galaxy.
- Anti-Ratio: No two adjacent cells in the grid may have digits that are in a 1:2 ratio.
Solution code: Row 3
