Can arrows bend?
Yes, some arrows make one or more right-angle turns.
What is the smallest possible circle value?
1, if the arrow passes through a single cell that must be 1.
Do arrow shafts repeat digits?
They follow standard Sudoku rules for their row, column, and box, so repeats are banned there too.
Is Arrow Sudoku math-heavy?
It uses addition, but the core is still Sudoku logic.
Where should I start?
Look for arrows with very high or very low circle values first.
