Another overlapping sudoku variant – now with 3 Sudoku X puzzles.
Warning: This puzzle is quite difficult even that it can be solved using only basic sudoku solving techniques. You must work on all three puzzles in order to get the solution. Also, I think you might get confused about the “fourth” puzzle which you might think exists in the center of the entire puzzle. Well – it doesn’t! The middle 9×9 does not have to be a valid puzzle! Look at the diagonals – they well define which 3 puzzles must be solved.
You can use the Twin Nonets technique, too!
Triple X.
