I was trying not to be too explicit about the highlighting, but as nobody has responded to my queries regarding cell connectivity, can anyone confirm that the letters of LIGHTNING should be highlighted as follows?
Row 1 columns 4,5,6
Row 2 columns 5,6
Row 3 columns 6, 7
Row 4 column 7
Row 5 column 8
I have no idea what the related 6 letter word which can be traced twice might be.
