3D Sudoku!

Now it’s just getting silly! 🙂

The Daily Telegraph has published an article on the Dion Cube™ – think of a cube made up of nine layers of Sudoku puzzles.

Not only must each number only appear once for each 3 x 3 square, each row and each column, it must also appear only once for each ‘vertical column’ – ie. each corresponding cell in all of the layers above and below it.

As they say, a picture is worth a thousand words, so enough with the talking and on with the puzzling! (note, you will need Adobe Reader for this one… Use the “Get Adobe Reader” link over on the right if you need the free reader software).

Have fun,

Tim
