Just One Cell Arrow Sudoku by Clover
This is the second of three Finals puzzles posting today.
or solve online in Penpa, or also solve online in SudokuPad as a new option (note: highly recommended to turn off “Mark Solved Digits” option if you use that in SudokuPad).
Author/Opus: This is the 20th puzzle from guest contributor Clover.
Rules: This Sudoku does not have a unique solution for the full grid (it actually has a large number of solutions), but there is exactly one cell in which a number can be logically placed that is fixed across all solutions. Find this cell and its unique value.
This puzzle follows Arrow Sudoku rules, so no number repeats in any row, column, or bold region. Some arrow shapes are in the grid; the sum of the numbers along the path of each arrow must equal the number in the circled cell. Numbers can repeat within an arrow shape.
Time Standards: This competition had 1-point (easy), 2-point (medium), 3-point (hard), or higher value puzzles. This would have been worth 2 points (medium category), roughly 1.5-2 minute target.
