@kmnagji The reason is that 5 can also appear in other columns in block 6 therefore it does not have to be in the highlighted column 7. In block 9, the 5 has to be in column 7 therefore it cannot be in column 7 in block 6 so we can remove it from column 7 in block 6.

hi you are missing the 49/49 pair already in box 1 and the 56/56 pair in box 8 with negates most of the logic you are trying to show.
cheers
