Reasoning 



R3C2 can only be <7>

R5C5 can only be <7>

R8C7 can only be <9>

R1C2 can only be <1>

R2C1 can only be <5>

R2C3 can only be <8>

R5C2 is the only square in row 5 that can be <2>

R4C7 is the only square in row 4 that can be <2>

Squares R5C4 and R5C6 in row 5 form a simple naked pair. These 2 squares both contain the 2 possibilities <58>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R5C8 - removing <58> from <14589> leaving <149>

R5C9 - removing <8> from <189> leaving <19>

Squares R4C5 and R6C5 in column 5 form a simple naked pair. These 2 squares both contain the 2 possibilities <36>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R2C5 - removing <36> from <1346> leaving <14>

R8C5 - removing <6> from <1246> leaving <124>

R9C5 - removing <36> from <1369> leaving <19>

Intersection of row 3 with block 2. The value <3> only appears in one or more of squares R3C4, R3C5 and R3C6 of row 3. These squares are the ones that intersect with block 2. Thus, the other (non-intersecting) squares of block 2 cannot contain this value.

R2C4 - removing <3> from <3467> leaving <467>

R2C6 - removing <3> from <1367> leaving <167>

Intersection of column 9 with block 6. The value <9> only appears in one or more of squares R4C9, R5C9 and R6C9 of column 9. These squares are the ones that intersect with block 6. Thus, the other (non-intersecting) squares of block 6 cannot contain this value.

R4C8 - removing <9> from <5789> leaving <578>

R5C8 - removing <9> from <149> leaving <14>

Intersection of block 7 with row 8. The value <1> only appears in one or more of squares R8C1, R8C2 and R8C3 of block 7. These squares are the ones that intersect with row 8. Thus, the other (non-intersecting) squares of row 8 cannot contain this value.

R8C5 - removing <1> from <124> leaving <24>

R8C6 - removing <1> from <1678> leaving <678>

R8C9 - removing <1> from <18> leaving <8>

Squares R7C8 and R9C8 in column 8 form a simple naked pair. These 2 squares both contain the 2 possibilities <16>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R5C8 - removing <1> from <14> leaving <4>

R6C8 - removing <1> from <14578> leaving <4578>

R3C8 can only be <9>

R6C7 can only be <3>
