Sum to 9 Sudoku recently appeared in Dutch Sudoku Championship 2016. I found it quite interesting Sudoku type and decided to create it. This is my first Sudoku of this type and hopefully I will be creating some more puzzles of this type soon. This puzzle reminds me to Next to 9 Sudoku and Before 9 Sudoku types.
This Sum to 9 Sudoku, I am posting as my 167th Sudoku in The League of Extraordinary Ladies & Gentlemen.
Rules of Sum to 9 Sudoku
