Another deconstruction puzzle, this time with the slingshot ruleset. Note for those who have solved other slingshot puzzles: the arrows look different from usual purely for practical reasons, to make them easier for me to implement, and to allow a pair of overlapping arrows that doesn't work quite so well with the usual design. Apart from the addition for handling empty cells, the ruleset is much the same.

Rules

• Place nine non-overlapping 3x3 square regions in the grid. Each region contains the digits 1-9 once each, and no digit repeats in any row or column. Cells outside regions do not contain digits.
• If a cell with an arrow contains the digit N, then the cell a distance N away in the direction of the arrow, and the cell beside the arrow, are equal (two empty cells are considered equal).
• If a cell with an arrow does not contain a digit, then no cell in the direction of the arrow is equal to the cell beside the arrow.
• For example, if r2c6 were a 3, then r1c6 and r2c9 would be equal (either both empty or both the same digit). If r2c6 were empty, then no cell from r2c7 to r2c11 would be equal to r1c6.
