Double Exclusion

(Published on 21. April 2025, 12:41 by Myxo)

An approachable puzzle I made a while ago for the amazing puzzle pack Quads on Parade (free to download).


Rules:

Sudoku: Place the digits 1-9 exactly once in each row, column and box.

Quadruples: Digits in a Quadruple circle must be placed at least once in the four cells touching that circle.

Double Arrow: The sum of the digits on a line between two circles is equal to the sum of the digits in the circles at either end of the line.

A genuinely fun puzzle with lots of sweet logic!
I found this one quite harder than casual 1 star puzzle but it still remained approachable throughout :)

Absolutely spectacular! One of my all time favorite "easy" puzzles to date.

This is excellent. Deceptive symmetry in looks and logic, that unravels smoothly.
