R3C1 is the only square in column 1 that can be <6>

R8C3 is the only square in block 7 that can be <5>

R7C6 is the only square in block 8 that can be <3>

Intersection of row 9 with block 7. The value <2> only appears in one or more of squares R9C1, R9C2 and R9C3 of row 9. These squares are the ones that intersect with block 7. Thus, the other (non-intersecting) squares of block 7 cannot contain this value.

R7C1 - removing <2> from <128> leaving <18>

R9C1 is the only square in column 1 that can be <2>

Intersection of column 3 with block 1. The value <3> only appears in one or more of squares R1C3, R2C3 and R3C3 of column 3. These squares are the ones that intersect with block 1. Thus, the other (non-intersecting) squares of block 1 cannot contain this value.

R2C2 - removing <3> from <135> leaving <15>

R3C2 - removing <3> from <1235> leaving <125>

Intersection of row 3 with block 3. The value <3> only appears in one or more of squares R3C7, R3C8 and R3C9 of row 3. These squares are the ones that intersect with block 3. Thus, the other (non-intersecting) squares of block 3 cannot contain this value.

R1C7 - removing <3> from <35> leaving <5>

R2C7 - removing <3> from <13568> leaving <1568>
