Galactic Galivanting

(Published on 3. February 2026, 16:11 by Chilly)

Recently I've been publishing older puzzles along with new ones I've just set. In keeping with that, I'll be publishing a new one today or tomorrow, but in the meantime, here's an older one I set for a Bremster 'Save the Galaxy' puzzle pack a few years ago. This one was the final puzzle in the pack, and you can find Bremster's YouTube solve here, if you're interested. It was a fun pack from lots of great setters, and I recommend checking out Bremster puzzle packs, and looking in on his YouTube stream if you get the chance.

The Rules:

  • Normal Sudoku rules apply.
  • Each circle represents the rotational centre of a spiral galaxy that is rotationally symmetric. The number next to a circle gives the sum of the digits in the galaxy centred on that circle. Galaxies must be one cell wide only, cannot branch, and must be orthogonally connected. Digits may not repeat in a galaxy. Not all cells need to be in a galaxy.

Oh, neat, I haven't played a Galaxies puzzle in... a year, I think? Combining it with sudoku like this is pretty rad! Though I'm very glad for the "one cell wide and cannot branch" rule, and for the non-repeating rule.
I didn't have too much trouble with this one, though I suspect that's because I've encountered galaxy puzzles before.

because this can be solved with standard PROCEDURE, plus (a lot of) BASIC SUDOKU, this qualifies as level 2.
