Will your puzzle solving find its target or miss the mark in this Slingshot Sudoku?

PDF

or solve online (using SudokuPad)

Theme: Short Shot

Author/Opus: This is the 176th puzzle from clover!, 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). Also, there are some “slingshot” cells marked in the grid with a circle and arrow. The circle indicates an adjacent cell whose value will be slingshot in the direction of the arrow. The number in the slingshot cell indicates how many cells away that circled cell’s value lands in the arrow’s direction. (For example, if a 3 is in R1C4 (the slingshot cell), and if the value in R2C4 pointed at by the circle is 5, then there would be another 5 three steps to the left of the slingshot in R1C1.)

If you solve in SudokuPad, the blunt end of an arrow will serve the same function as a circle shown here.
