PUZZLE NO. 59 : GREATER NEIGHBOURS SUDOKU

I had created this variant for the Puzzle Innovation Contest in WSC 2017. Sharing it on my blog.


RULES : Classic sudoku rules apply. Some cells are marked with circles. All orthogonal ( vertical & horizontal ) neighbours of circled cells will have numbers greater than the number in the circled cell. All possible circles are marked.
