9x9 Fillomino Skyscrapers
(Published on 10. August 2020, 22:28 by Jesper)
Standard Fillomino rules apply:
- Divide the grid into orthogonally connected regions
- Each square must contain a number equal to the number of squares in its region
- No two regions of the same size may share an edge
The numbers outside the grid are skyscraper clues:
- Consider each square as a skyscraper of height equal to its number
- A clue outside the grid shows how many skyscrapers can be seen in the indicated row or column from that direction
- A skyscraper is obscured if there is another skyscraper of greater or equal height in front of it

Superb ! Surprised by how this solved with so few clues to deal with ! Once you spot the main trick at the beginning, it actually solves very quickly and smoothly. Thanks :)

Pleasantly surprised to solve this. I broke it a few times and thought I was repeating the same mistake, but it transpired that I had not overlooked anything fundamental, I'd just been blind to a possible arrangement. A lot of it was actually forced.

Brilliant minimal construction! Seems impossible at first.

Wonderful puzzle! The grid seems absurdly empty but the clues pull their weight.

It is such a pleasure to go through all your Fillomino variants. What I love about this one is how clever the setup is. Although I thought I had a good grasp on it, I was still pleasantly surprised by how it all unfolded.

Gave this one a go, even though skysrapers isn't something I'm great on, but was an enjoyable solve, once I worked out how to start!

Ganz großartig! Hat viel Spaß gemacht! (Anmerkung: Die Rätsel 1ET/0D9 sind weitere geniale Konstruktionen dieses Typs)

Nicely done! Great thanks to the author.
It was like a breath of fresh air amid a muddy stream of spamudoku.
