Hi, Mike! Welcome to the forum.

-- The only way a "6" can fit in row 2 is if it goes in the top right 3x3 box (that is, at r2c7 or r2c8). So you can eliminate "6" from r1c7, r1c9, r3c7, and r3c9.

That should get you going. dcb Smile

Thanks. It broke it wide open. I do not know why I did not see it.
