R5C9 is the only square in row 5 that can be <8>

R3C3 is the only square in row 3 that can be <8>

R2C7 is the only square in row 2 that can be <8>

R6C5 is the only square in row 6 that can be <5>

R8C2 is the only square in row 8 that can be <8>

R9C9 is the only square in row 9 that can be <4>

R8C5 is the only square in row 8 that can be <4>

R7C5 is the only square in column 5 that can be <3>

R7C7 can only be <5>

R7C9 can only be <1>

R3C1 is the only square in row 3 that can be <1>

R1C8 is the only square in row 1 that can be <1>

R9C3 is the only square in row 9 that can be <1>

Intersection of row 1 with block 1. The value <7> only appears in one or more of squares R1C1, R1C2 and R1C3 of row 1. 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 <7> from <5679> leaving <569>

R2C2 - removing <7> from <5679> leaving <569>

Intersection of row 4 with block 4. The value <7> only appears in one or more of squares R4C1, R4C2 and R4C3 of row 4. These squares are the ones that intersect with block 4. Thus, the other (non-intersecting) squares of block 4 cannot contain this value.

R5C1 - removing <7> from <234679> leaving <23469>

R5C2 - removing <7> from <679> leaving <69>

Intersection of column 7 with block 6. The value <2> only appears in one or more of squares R4C7, R5C7 and R6C7 of column 7. These squares are the ones that intersect with block 6. Thus, the other (non-intersecting) squares of block 6 cannot contain this value.

R4C9 - removing <2> from <239> leaving <39>

Intersection of block 5 with row 5. The values <279> only appears in one or more of squares R5C4, R5C5 and R5C6 of block 5. These squares are the ones that intersect with row 5. Thus, the other (non-intersecting) squares of row 5 cannot contain these values.

R5C1 - removing <29> from <23469> leaving <346>

R5C2 - removing <9> from <69> leaving <6>

R5C8 - removing <9> from <3469> leaving <346>

R6C3 can only be <2>
