How to Play
Arrow Sudoku follows standard Sudoku rules, but adds arrows across the grid. Each arrow starts in a circle and passes through a straight or bent line of cells. The digits along the arrow's shaft must sum to the digit in the circle.
Circles are cells like any other, so they also obey row, column, and box constraints. The arrow sums add powerful extra restrictions.
Controls
Click a cell and type a digit. Arrow lines are usually drawn clearly on the grid.
Scoring
Time and accuracy determine your score. Arrow constraints can dramatically speed up solving once understood.
