PUZZLE NO. 40 : ARROW SUDOKU


I have long been trying to create an arrow sudoku with no given numbers. It is comparatively easier to create a numberless thermo sudoku . But creating a numberless arrow sudoku is more challenging because the set combinations are limited as compared to a thermo sudoku.
