Space in Symmetry
(Published on 15. December 2025, 23:07 by Killer Joe)
This is my first galaxy puzzle. Estimated difficulty on discord was between 3 and 4 stars. Once again, you are the judge and I'm terrible at estimating. Hope you enjoy!
Hello.
Normal sudoku rules apply.
Shade some cells to form one orthogonally connected galaxy that is 180° rotationally symmetric around the centre of the grid. Each group of unshaded cells must also connect orthogonally and touch one edge of the grid.
Digits inside the galaxy count double their value for the killer cages. Values inside a killer cage sum to the total given inside each cage.
A digit in a circle must be odd.
Have fun.
Solution code: Row 9, first 6 digits.

Very much enjoyed that, felt super consistent and fair the entire way through. A lovely journey through the stars.

fairly hard AND approachable.
not a contradiction, because the difficulty shows up as EFFORT and ORDINARY logic, not specialized sudoku experience.

Fun puzzle! Not too easy, but still quite approachable. The shading and cages had some neat interactions as well. Three stars feels about right to me.
