I am trying to use excel to help solve the big SuperSudoku puzzles for
myself. I am OK with the algorythm but am not sure of the best way to
implement the code to carry out each stage of the process.

In particular I want a grid of six cells to be highlighted each time a
selection change takes place. Each of the sixteen cells represent the
possible candidates for the unique symbol that shall take their place. These
will be eliminated and the sixteen cells merged to contain the correct
symbol.
This is a section of what I mean as an example.

0 1 2 3 0 1 2 3 4 0 1 2 3
4 5 6 7 4 5 6 7 4 5 6 7
8 9 A B 8 9 A B 8 9 A B
C D E F C D E F C D E F
0 1 2 3 0 1 2 3 0 1 2 3 0 1 2 3
4 5 6 7 4 5 6 7 4 5 6 7 4 5 6 7
8 9 A B 8 9 A B 8 9 A B 8 9 A B
C D E F C D E F C D E F C D E F
0 1 2 3 0 1 2 3 0 1 2 3 0 1 2 3
4 5 6 7 4 5 6 7 4 5 6 7 4 5 6 7
8 9 A B 8 9 A B 8 9 A B 8 9 A B
C D E F C D E F C D E F C D E F


Do I use the command myRange.Offset(+X,X) or just some other form of
Range("A1:D4") to move the active range with the grid of 16 as shown? Any
suggestions appreciated.
