Dutch Flat Mates (Tessellation)

(Published on 20. September 2025, 01:59 by aqjhs)

After solving ChinStrap's Skyscraper and Counting Circles Tessellations I got inspired to make this puzzle.

  • Tessellation rules:
    • Place digits from 1-9 in each square and octagonal cell.
    • Cells sharing an edge can't have the same digit.
    • Each horizontal row and vertical column contains a non-repeating consecutive set of digits in any order.
  • Dutch Flatmates: Every 5 in the grid must have a 1 directly above it, or a 9 directly below it. It may have both, but it doesn't need both.
  • Adjacent digits along an orange line must have a difference of at least 4.

It took me too much time to see the word "consecutive" in the rules and too much time to catch onto all the implications of that. But I still had a blast despite not being the best at solving it! Thanks for the puzzle.

Such a great puzzle!
I took me a bit of time to understand the underlying logic, but it was so beautiful!
