How to play Arrow Sudoku
The circle is the total, not part of the sum. Unlike Killer cages, an arrow path does not impose its own no-repeat rule; repeats are allowed only where normal Sudoku rules allow them.
The rules
Fill each row, column, and 3×3 box with 1–9, without repeats. Digits along an arrow add up to the digit in its circle. Arrow digits may repeat when ordinary Sudoku rules allow it.
A useful first move
Longer arrows need larger circle digits because every path cell is at least 1. Combine the sum with row, column, and box restrictions to remove impossible combinations.
An arrow with path digits 2 and 5 needs a 7 in its circle. If a circle is 4 and one of its two path cells is 1, the other path cell must be 3.
Controls, difficulty, and saved games
Choose Beginner, Easy, Medium, Hard, or Expert above. Select an empty cell, then tap a number or use your keyboard. Notes let you pencil in candidates; three hints are available. Three mistakes end the puzzle.
Every mode and difficulty keeps a separate save in this browser. You can switch puzzles and return to your place. Clearing site data removes these saves; they do not sync with another device or the iPhone app. Settings include night mode and optional automatic cell advancement.
Correct entries earn points. High scores are stored by mode and difficulty and update only when beaten; completed-puzzle count and day streak are shared.
