It is chaos, or is it?

(Published on 1. April 2026, 00:00 by 72kchunshuai)

Today is the perfect day to share my weirdest ideas, I think.

Rules:

  • Chaos Construction: Divide the grid into regions of orthogonally connected cells. Place the digits 1-6 once each in every row, column, and region.
  • Circles: A digit in a circle indicates exactly how many circles contain that digit. Additionally, it indicates how many of the up to nine cells in its 3×3 neighborhood (including itself) belong to the same region as the circle.
  • Squares: A digit in a square indicates how many of the up to eight neighboring cells (excluding itself) are in a different region from the square. Not all possible squares are given.
  • Numbered rooms: Clues outside the grid indicate the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction. Furthermore, the first N cells must all be in the same region, and the (N+1)-th cell (if it exists) must be in a different region.

Solution code: Digits in column 5 from top to bottom with (-) in between for region borders.

This one was five stars for me... Until I remembered that circles indicate how many digits are in circles!

So I guess it was a self-April-Fool's for me! Thanks for the funny puzzle!

this is only 1* if you assume the region layout
