Sudoku Compilation: Clone Sudoku

Hi folks,
I just managed to finish another installment of our Sudoku Compilation. To be honest, I am not as happy with today’s six puzzles as I was with those from the first two groups in the series. But then, it so happens that I find Clone Sudokus generally less exciting than other variants. They belong to a category one might call “Equality Sudokus”, meaning that cells are denoted which must contain the same entry (Palindrome Sudokus are another somewhat popular representative of the same category).
