Sternenburg (Star Battle Fortress Fillomino)

(Eingestellt am 3. November 2026, 06:31 Uhr von PrissyP)

Rules

Fortress Fillomino:

  • Divide the grid into orthogonally connected regions and fill each cell with a number (not necessarily single-digit) showing the number of cells in the region to which it belongs.
  • Each region must be either high (strictly larger than all of its orthogonal neighbours) or low (strictly smaller than all of its orthogonal neighbours).

Star Battle:

  • Fill some cells with stars so that each row, column, and region contains two stars.
  • Stars cannot be placed in adjacent cells that share an edge or corner.
  • One star has been given.

Kropki Dots:

  • A white dot separates regions whose size differs by 1.
  • A black dot separates two regions where one is twice the size of the other.
  • Not all possible dots are necessarily given.

Battenburg:

  • A Battenburg marking is placed on a point where the four surrounding cells form a 2×2 checkerboard of high and low cells (diagonally opposite cells are both high or both low).
  • All such points are marked.

I love a good "build your own star battle" puzzle. The integration with fortress fillomino was a great idea, I thought.

Great puzzle, very smooth and a clear path overall.
As it wasn't super clear to me: The Answercode is just the last digit for any two-digit number.

Thanks, I am glad you enjoyed it. I edited the solution code description so it is more clear.

This looks like a really neat combination. I like how the star placement and the region sizes have to work together, it feels like every clue will pull in two directions at once. I have not tried a fortress Fillomino before, so I am looking forward to giving this one a proper go. Thanks for putting it together.

Thanks for your interest, I hope you enjoy the puzzle. Feel free to ask for a hint anytime on Discord(prissyp0431) or here. Fortress Fillomino Takes a little bit to get used to but is a lot of fun!
