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 sniqes 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?
