The Queen's Quad

(Published on 26. January 2024, 06:06 by Scojo)

Rules:
  • Normal sudoku rules apply: Place the digits 1-9 once each in every row, column, and 3x3 box.
  • Anti-Queen: The digits 8 and 9 may not be a chess queen's move away from another of the same digit anywhere in the grid, meaning any diagonal in the grid can only have a maximum of one 8 and a maximum of one 9.
  • Quadruples: Digits in a circle must appear at least once in the four cells surrounding the clue.

I forgot about the anti- queen rule and couldn’t figure out why I kept getting stuck. I really enjoyed this puzzle once I remembered all the rules!
