Point and Sweep [Duality]

(Published on 14. May 2025, 22:16 by timotab)

  • Normal Sudoku rules apply: place the digits 1 to 9 in every row, column, and box, once each.
  • Digits along arrows must sum to the value in the attached circle.
  • Additionally, a circle's neighbourhood includes the cell containing the circle, and any cell touching it (on an edge or corner). The digit in the circle is the number of cells in its neighbourhood that have the same odd-even parity as the circled digit.

basic sudoku + basic parity counting + basic arrows
therefore, almost GAS
since GAS level here = 0, this one is level 1

I'm desperate for someone to teach me how to solve this one. It looks really fun but I can't understand how to begin to solve it.

Super cool, I found this one easier than One Way Street for some reason. GG.

A little more challenging than the previous iteration of this ruleset, but still very fair and smooth.
