description Arrow Sudoku Overview
Arrow Sudoku is a logic puzzle variant that overlays standard Sudoku rules with arithmetic constraints. The grid features arrows originating from empty circles. The digit placed in a circled cell must equal the sum of the digits placed along the corresponding arrow's path. While standard Sudoku rules dictate that digits one through nine cannot repeat within a row, column, or 3x3 box, digits along an arrow may repeat if allowed by these base constraints.
help Arrow Sudoku FAQ
How do the arrows work in Arrow Sudoku?
In Arrow Sudoku, a standard Sudoku grid is filled with lines that originate from a circled cell. The digit placed inside the circle must equal the sum of the digits placed along the corresponding arrow's path.
Can digits repeat along the arrow's path in Arrow Sudoku?
No, standard Sudoku rules still apply, meaning digits cannot repeat within a row, column, or 3x3 box. Therefore, if an arrow's path stays entirely within one box or row, the digits along that path must be completely unique.
What is a common solving strategy for Arrow Sudoku?
Solvers typically look for small target numbers in the circles, as they drastically limit the possible combinations on the arrow's stem. Large target numbers are also helpful because they force the highest possible digits, like 9 and 8, into the stem cells.
Where can I play Arrow Sudoku puzzles?
Arrow Sudoku puzzles are frequently featured on the popular puzzle YouTube channel Cracking the Cryptic. You can also find interactive versions of these arithmetic Sudoku variants on daily puzzle websites and mobile apps.
