Arrow Sudoku is a popular Sudoku variant that combines classic Sudoku rules with additional arrow clues. Use logic to fill the grid so that all Sudoku and arrow constraints are satisfied.
Classic Sudoku Rules
Fill every empty cell with a digit from 1 to 9.
Each row must contain every digit from 1 to 9 exactly once.
Each column must contain every digit from 1 to 9 exactly once.
Each 3×3 box must contain every digit from 1 to 9 exactly once.
Arrow Sudoku Rules
Each circle contains a digit equal to the sum of the digits along its connected arrow.
The digits on an arrow must add up exactly to the number shown in the circle.
Standard Sudoku rules still apply to all cells in the grid.
Use both Sudoku logic and arrow sums to determine the correct digits.
Example
If a circle contains the number 8 and its arrow covers two cells, those cells could contain 3 and 5 because 3 + 5 = 8.
Solving Tips
Start with arrows that have very small or very large totals.
Use missing digits in rows, columns, and boxes to narrow possibilities.
Combine Sudoku elimination techniques with arrow sum constraints.
Look for arrows where only a few digit combinations are possible.
Arrow Sudoku puzzles provide an enjoyable mix of arithmetic reasoning and classic Sudoku deduction, making them a favorite among logic puzzle enthusiasts.
