Butterfly Killer Sudoku X

It’s been a while since I last posted a Butterfly Killer, let alone one with the “X” factor. So, here it is – and to spice it up a little, I made it quite hard (altho I expect someone to get back in 20 minutes and say it was way too easy). So, you get 4 of your favorite Killer Sudoku puzzles in this one, heavily overlapped, plus all 8 diagonals must not contain duplicate numbers. Make sure you remember Twin Nonets and Twin Diagonal Triplets techniques! Butterfly Killer Sudoku X for Thursday, September 21 – IQ – this is the only place you can find this kind of Sudoku puzzles!
