Arrow Sudoku

Rules

An arrow is a sum: the digit in the circled cell equals the total of every digit along the shaft. Arrows are drawn from a short arm, so the sums stay small and the deductions stay sharp.

• The circle digit equals the sum of all digits on its arm.
• The circle itself is not part of the sum.
• Digits repeat freely on the arm as long as sudoku allows it.
• A two-cell arrow is just a pair: circle = the single arm cell.

Good to know

Ordinary sudoku rules still apply underneath the variant: every row, column and 3×3 box holds 1–9 exactly once. The extra rule sits on top and is usually what breaks the puzzle open.
