Find this cell and its unique value.<\/p>\n<p>This puzzle follows Kropki Pairs Sudoku rules, so no number repeats in any row, column, or bold region. If a white circle is given between two adjacent cells, then the two numbers in those cells must differ by 1. If a black circle is given between two adjacent cells, then the two numbers must have a ratio of 2. Pairs of cells without circles can have any relationship.<\/p>\n<p><b>Time Standards:<\/b> This competition had 1-point (easy), 2-point (medium), 3-point (hard), or higher value puzzles.
