Outside Twodoku

by | August 27, 2012

Here is something completely new! 🙂 A new variant of Sudoku puzzles, previously unseen anywhere!

Two overlapping Outside Sudoku puzzles arranged in the Twodoku format. What else needs to be said? 🙂 Well, just that some clues had to be left on the inside, too. Those are regular Sudoku clues and you use them as usual. The clues outside of the grid tell you which number(s) MUST appear somewhere in the 3 closest cells. This also means that they can’t appear in the 6 cells farthest away.

That’s it. Use all clues in order to solve the puzzle. If you have doubts – ask here!
