## Disjoint Group Killer

For fans of Killer Sudoku, Samurai Sudoku and other variants

### Disjoint Group Killer

I am expanding from KiMos into DG killers

In DG Sudoku the same Spot in each Nonet is treated as another exclusion zone (i.e. it contains the numbers 1 to 9 once and once only). See www.meneske.no

From a killer viewpoint the benefit is that you can lay the cells out in two different formats: row-column and also nonet-spot. Hence you can put some of your cages in one layout and some in the other. See sniqe’s site www.4dsudoku.com

My first example will be loaded up tomorrow morning (GMT 9+). I am putting up the solution walkthrough also, as a help in case of any confusion.

A couple of DG questions:
If there are about 1.2 trillion Sudoku grids how many DG grids are there?
Has anyone created a DG Dion Cube?

Appologies, I forgot to print out the new format before putting it up.

DG Killer Puzzle 1 is now reformatted to fit in one A4 page, and will be uploaded shortly.

My second DG Killer is up. For once I have made a symmetrical puzzle.

I hope that you all enjoy it over the weekend.

Have you any comments on the first one?

I have posted my first full DG KiMo (www.diceboard.co.uk)

It appears to me that the two game concepts work together, but I welcome your views.

I have put together a special DG KiMo for Easter. It has diagonal cages (which are a straight copy from DJApe) and it is reasonably pretty obeying almost all symmetry rules.

The first few values are easy to place but then you get into complicated interactions between the two layouts.

It took me a few hours to solve - admittedly while marking up. I am interested in hearing your times and your solutions as I am by no means convinced that my solution is optimal.

At Jean-Christophe's suggestion I have put up an explanation of how DG killers on a double layout work, for those of you who might have been confused.
