Coordinated Chaos
(Published on 30. July 2025, 13:05 by mellowrobinson)
- Coordinate Arrows:
- The digits on a green arrow give the coordinates of a cell in the grid. The digit at the base of the arrow indicates the row number, and the digit at the head of the arrow indicates the column number. The referenced cell is one cell of a domino (two cells that share an edge) that has the same sum as the digits on the arrow. Some of the arrows have no given arrow tip and must be deduced.
- Regions:
- Locate nine 9-cell orthogonally connected regions in the grid.
- Both cells of a Coordinate Arrow are in the same region. The cell it references and the other cell of its domino are also in the same region as the arrow.
- The digit in a cell with a small blue arrow counts the total number of cells seen in the indicated direction which are in the same region as that cell, including itself. Region borders block vision. A cell with two blue arrows counts each direction separately.
- Fill the grid with the digits 1-9 so there are no repeats in any row, column, or region.
Solution code: Column 9, with / for region borders; ie 123/45/6789

The break in is tricky but as the whole puzzle very rewarding. Great setting thx.

A nice easier (2-3 star) chaos puzzle. Definitely loved it, and definitely loved the tricks.

That was amazing! Your chaos constructions are hands down my absolute favourite puzzles.

Love finding CC puzzles I can actually do :D It took me a little bit to wrap my head around the coordinate arrows. That one region in particular made me glad I didn't make an assumption I'd considered making.

Very approachable. Good introductory puzzle for first time CC solvers.

I just got started and I'm stuck. The blue arrows in r3c1 and r1c3 would seem to be not only in the same region but also the same digit ... which means I must be misunderstanding the instructions about the blue arrows incorrectly. In a cell with two blue arrows, does the digit in the cell indicate the total region cells seen in TOTAL in both directions?
- Hi, the blue arrows count each direction separately, so for example if a cell with two arrows was a 2 it would see itself and one more cell on both sides (seeing 3 in total).
