While an Arrow Sudoku may have some numbers repeating on the arrow paths, in this variation there absolutely must be a repeat.

or solve online (using SudokuPad)

Author/Opus: This is the 129th puzzle from Bill Murphy, part of the Genuinely Approachable Sudoku (GAS) team.

Rules: Standard Sudoku rules (insert a number from 1 to 9 into each cell so that 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. At least one of the numbers along the path in each arrow must be repeated. (E.g., 1 + 1 + 7 = 9 would be a valid sum but 2 + 3 + 4 = 9 would not, as no number repeats.)

Theme: Not an Arrow Sudoku

Author/Opus: This is the 121st puzzle from Clover, part of the Genuinely Approachable Sudoku (GAS) team.
