Clueless Killer Sudoku #3

A while ago I posted 2 Clueless Killer Sudoku puzzles and for the second one I suggested that you shouldn’t attempt to solve it. Well here is another puzzle of the same kind. I won’t make any suggestions this time – I hope you will enjoy the puzzle. 🙂 Again, thanks to Ruud from for inventing the “clueless” concept. Unlike Samurai Sudoku, in this puzzle 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, February 19, 2007 – this is the only place you can find this kind of Sudoku puzzles!

    First clueless, personally a fan of Loco, but! A question, as this is my first clueless (Did I mention this is my first clueless? Did I mention I am.. well.. somewhat clueless?)
    Each puzzle (9×9) has its own numbers, I understand that they do not OVERLAP with each other, but the sides that butt up against each other, do those numbers run non-consecutively? I notice that there are occassionally numbers that are consecutive in adjoining puzzles, but just wanted to clarify this for my clueless self, and any others who may be clueless as well..
