This Touchy Trio Sudoku is my second Sudoku of this type. Earlier Touchy Trio Sudoku was published with the title Touchy Trio Sudoku (Daily Sudoku League #139). This Sudoku type is the mix of Trio Sudoku and Touchy Sudoku puzzles. It will be suggested that if someone has solved Trio Sudoku or Touchy Sudoku earlier, should try to solve these type of puzzles before attempting this one as this is for experienced players and is rated a tough puzzle.
