Restricted Skylines
(Published on 15. September 2022, 15:55 by FullDeck-Missing)
Each digit in the grid is a "skyscraper" whose height is the digit in that cell. Taller skyscrapers obscure the view of smaller ones. Clues outside the grid tell how many skyscrapers are visible looking across the row or column from the direction of the clue.
Isotropic groups: Each group of nine cells occupying the same relative position in the nine boxes is isotropic: all nine are from {123} or all nine are from {456} or all nine are from {789}.

This was surprisingly really fun. The break in was something really unexpected. After that the puzzle was rather straightforward, but fun nevertheless.

At first glance, I thought this puzzle was impossible with only six clues provided. Then I quickly realized that "isotropic groups" is just a fancy way of saying "swordfish". Lovely puzzle.

Wow. So elegant. Amazing it solves as easily as it does with so little information in the grid. Satisfyingly chromatic as well.
>> Thank you for your kind words! Very glad it was satisfying :)

I thought it was going to be impossible, but I saw the break-in and had a lot of fun solving it.
