This Disjoint Groups Sudoku was part of the Sudoku Mahabharat 2016 Twisted Classic test at Logic Masters India website. Prior to creating this puzzle, I was not good at solving Disjoint Groups Sudoku. My earlier attempts to create Disjoint Groups Sudoku have resulted into created almost the Classic Sudoku. When we decided to include this Sudoku type in Sudoku Mahabharat, I have to practice a lot for this Sudoku type and because of this only I improved on solving this Sudoku type but also maybe this is the first Disjoint Groups Sudoku where variation rule of Disjoint Groups is used many times. Anyway, I will try to create more Sudoku puzzles of this type later.
Now I am posting this Disjoint Groups Sudoku in the Fun With Sudoku Series as my 153rd Sudoku in this series. Can you solve this Sudoku puzzle?
