I have taken to using a 3 digit technique for logging my moves on
a Sudoku puzzle.

It reminds me alot of the 'Back Coordinate System' my wife and I
developed. We divide the back into six quadrants and each quadrant,
(or would it be called a Hexant...) into six spaces. Then when you
need a scratch, just say, four two.

Anyway, for Sudoku, the nine 3x3 boxes are the first coordinate,
the number within the 3x3, numbered from upper left to bottom right
is the second coordinate, and the value is the third.

Does anyone else do this?


I find that it helps recover if a mistake in logic is made and not
found out till several moves later.


Lars.
