New Variant

Hi people,

I have invented a new variant of sudoku. The rules are more mathematically balanced than the original and my puzzles are far, far harder!

Please check it out at:
You will need:
1. Acrobat reader (free at
2. To read the instructions first!
3. Java (free at

Please let me know what you think!

Well, I didn't know that others had allready done it... but I still think that I did it first... certainly before July 2005.

Either way, I don't think that enough attention has been paid to this variation, which is more mathematically balanced than any other form... by which I mean that the row and column are like siblings - and they are cousins with another sibling pair, the box and the hyperbox... and the puzzles can be re-written switching any sibling pair or by swapping the cousins en masse... see a description of this in "solving techniques" in the help file on my website.

I hope that this post will generate some interest from people ready for a challenge!

I have not currently got an example of the hardest puzzles I have created on my website because they are too hard... I have puzzles which I would bet substantial money on nobody being able to solve (without using T&E).
