Difficulty overview
About Arrow Sudoku
Arrow Sudoku places arrows on the grid, each starting from a circled cell. The digits in all cells along the arrow (not including the circle) must sum to the digit placed in the circled cell. Since the maximum digit is 9, long arrows with many cells are highly constrained. Arrow Sudoku often combines beautifully with standard elimination and candidate logic.
Solving Techniques for Easy Level
| Technique | Description | Level |
|---|---|---|
| Arrow Sum Bounding | The circle digit equals the sum of all arrow shaft cells. A 3-cell arrow with circle 5 means the three shaft cells average under 2 — severely constraining options. | Beginner |
| Bifurcation on Short Arrows | For 2-cell arrows with a small circle (e.g., 3), only (1,2) or (2,1) works — enumerate cases to find forced placements quickly. | Beginner |
