Clueless Killer Sudoku

I promised something special with the Clueless concept before – and here it is: my first ever Clueless Killer Sudoku puzzle. Again, thanks to Ruud from www.sudocue.net for inventing the “clueless” concept. There are 9 Sudoku puzzles with no overlapping regions! If you attempt to solve them individually – you won’t get far. Here is where the “clueless” part comes in: in all of those 9 puzzles, the center nonet is just one cage. As you plug in your numbers, center nonets (shaded in grey) start filling up. The trick is that those 9 center nonets, put together, also constitute a valid Sudoku puzzle. So, when you run out of ideas, start working on the 10th puzzle and it will give you enough information to solve the whole lot. Those 10 puzzles together have, of course, a single solution. Clueless Killer Sudoku for Monday, April 10 – this is the only place you can find these kind of Sudoku puzzles!
