The Odd Diagonal
(Published on 19. September 2025, 20:52 by billybeth)
Normal Sudoku rules apply.
Each blue circle contains a digit that tells how many odd numbers (including itself) appear on at least one of its diagonals (to clarify - all cells in the grid have two diagonals). The diagonal the number refers to is the 'Odd Diagonal'. If the digit in the blue circle sees itself on the Odd Diagonal that digit is marked with a red square. If it sees itself on its other diagonal that digit is marked with a green square. All squares are given and all numbers in circles are different.
