| Or if you just use VH moves (i.e. X Wings, XY Wings, and XYZ Wings), the 16-4 XY Wing at r58c7,r7c9 (-4r4c9) opens up a 46-1 XY Wing at r4c19,r7c1 (-1r7c9) which solves it. There's also an X Wing on 6's in columns 1 and 9 but it doesn't solve it. (It looks like you'd still have to use the XY Wings that I mentioned in order to solve it.) |
