That's what I used. Could someone post the puzzle after basics so that I can see the W wing?

Doesn't the 69 UR only remove the 9s in r5c1 and r7c1? The puzzle becomes the one below, how does the UR kill the 4 in r9c1?

1. Unique Rectangle with 69
2. Don't remember this step. But I eliminated a "2&q ...

arjun,

I suppose you are referring to the pattern in rows 2 and 8 / cols 3 and 7.

Careful, this is NOT a UR pattern.

For the "deadly" pattern, the two "floor" cells must b ...
