R4C4 is the only square in row 4 that can be <1>

R4C6 is the only square in row 4 that can be <6>

R6C5 is the only square in row 6 that can be <8>

R9C9 is the only square in row 9 that can be <7>

R6C4 is the only square in column 4 that can be <7>

R4C2 is the only square in row 4 that can be <7>

R5C7 is the only square in row 5 that can be <7>

Intersection of row 3 with block 1. The value <1> only appears in one or more of squares R3C1, R3C2 and R3C3 of row 3. These squares are the ones that intersect with block 1. Thus, the other (non-intersecting) squares of block 1 cannot contain this value.

R2C1 - removing <1> from <12346> leaving <2346>

R2C2 - removing <1> from <12349> leaving <2349>

Intersection of row 7 with block 9. The value <6> only appears in one or more of squares R7C7, R7C8 and R7C9 of row 7. These squares are the ones that intersect with block 9. Thus, the other (non-intersecting) squares of block 9 cannot contain this value.

R8C8 - removing <6> from <245689> leaving <24589>

R8C9 - removing <6> from <12468> leaving <1248>

Intersection of column 4 with block 8. The value <5> only appears in one or more of squares R7C4, R8C4 and R9C4 of column 4. These squares are the ones that intersect with block 8. Thus, the other (non-intersecting) squares of block 8 cannot contain this value.

R7C5 - removing <5> from <2359> leaving <239>

R8C5 - removing <5> from <23459> leaving <2349>

R9C6 - removing <5> from <245> leaving <24>

Intersection of column 7 with block 9. The value <5> only appears in one or more of squares R7C7, R8C7 and R9C7 of column 7. These squares are the ones that intersect with block 9. Thus, the other (non-intersecting) squares of block 9 cannot contain this value.

R7C8 - removing <5> from <2569> leaving <269>

R8C8 - removing <5> from <24589> leaving <2489>

R9C8 - removing <5> from <2459> leaving <249>
