Find this cell and its unique value.<\/p>\n<p>This puzzle follows Killer Sudoku rules, so no number repeats in any row, column, or bold region. The sum of the numbers in each cage must equal the value given in the upper-left corner of that cage. Numbers cannot repeat inside a cage.<\/p>\n<p><b>Time Standards:<\/b> This competition had 1-point (easy), 2-point (medium), 3-point (hard), or higher value puzzles.
