Focus on the interaction of Box 2 and Column 6.

i still dun get it....be more specific plz...

One more time: The 3's in box 2 are both in column 6. Therefore one of these cells must be 3 and no other cell in column 6 can be 3.

Either r1c6 or r2c6 must eventually be a 3. No other cells in box 2 have that candidate.

It follows therefore that 3 can be eliminated as a candidate in r9c6 and r8c6.

When you eliminate them, you immediately get r9c6=2

All singles after that.
