Dutch Flats with a Difference
(Published on 2. July 2025, 19:06 by phil_the)
This puzzle was created for one of Scojo's Setting Saturday puzzle prompts back in October 24 suggested by GDC and Flinty. This was around the time of the anniversary of the first Dutch Flat Mates Puzzle. I decided to combine Flat Mates with a constraint of my own invention called Difference Arrows.
.
Each row, column & 3x3 box contains the digits 1-9.
Each 5 in the grid contains a 1 in the cell immediately above it, or a 9 immediately below. It may have both but doesn't need both.
Digits in a circle equal the difference between the sum of the digits along each attached arrow.
