Hi,

I looked at this site, and in the Beginner's section, there were two techniques which I have never heard of - Mutant Pointing and Mutant Claiming - and I can find no other references on the Web to these techniques.

My question is: both examples show 'irregular box shapes' - my question is 'are these the ones to use, or are there other possibilities for these box shapes?' If you are able to help - or, at least, point me in the right direction, I would much appreciate it.

Best regards, Neil

The boxes can be of any shape, from long squiggly snakes to just a few cells transferred here and there like the Sudoku Snake examples.

It's impossible for these techniques to exist in a regular arrangement, as a cell has to be in the same row AND column as parts of a box without actually being in that box.

Here's an example from the Sudoku Snake website of another irregular box arrangement.

I noticed a mutant pointing in it, where the 2 in the cell just below the top-left corner can be eliminated (thanks to the squiggly box that has the 1, since all the remaining 2's in that box 'point' to it)
