## Reasoning

R7C3 can only be <5>

R7C8 is the only square in row 7 that can be <9>

R7C4 is the only square in row 7 that can be <7>

R9C1 is the only square in row 9 that can be <6>

Squares R3C6 and R3C7 in row 3 form a simple naked pair. These 2 squares both contain the 2 possibilities <28>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R3C2 - removing <28> from <1278> leaving <17>

R3C8 - removing <8> from <378> leaving <37>

Squares R3C3 and R8C3 in column 3 form a simple naked pair. These 2 squares both contain the 2 possibilities <13>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R1C3 - removing <3> from <36> leaving <6>

R2C3 - removing <3> from <3469> leaving <469>

R6C3 - removing <1> from <1469> leaving <469>

Squares R3C6 and R9C6 in column 6 form a simple naked pair. These 2 squares both contain the 2 possibilities <28>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R2C6 - removing <28> from <258> leaving <5>

R4C6 - removing <2> from <12567> leaving <1567>

R5C6 - removing <8> from <1568> leaving <156>

R6C6 - removing <8> from <15678> leaving <1567>

R1C9 is the only square in row 1 that can be <5>

R8C9 is the only square in column 9 that can be <7>

R3C8 is the only square in column 8 that can be <7>

R3C2 can only be <1>

R3C3 can only be <3>

R8C3 can only be <1>

R8C1 is the only square in column 1 that can be <3>

Squares R7C2 and R8C2 in column 2 form a simple naked pair. These 2 squares both contain the 2 possibilities <28>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R1C2 - removing <28> from <278> leaving <7>

R2C2 - removing <28> from <248> leaving <4>

R2C3 can only be <9>

R6C3 can only be <4>

Squares R3C7 and R7C7 in column 7 form a simple naked pair. These 2 squares both contain the 2 possibilities <28>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R2C7 - removing <28> from <268> leaving <6>

R8C7 - removing <28> from <2458> leaving <45>

R9C7 - removing <28> from <1248> leaving <14>

Squares R4C9<19>, R5C9<189> and R6C9<189> in column 9 form a comprehensive naked triplet. These 3 squares can only contain the 3 possibilities <189>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R2C9 - removing <8> from <238> leaving <23>

R9C9 - removing <18> from <1238> leaving <23>

R9C7 is the only square in row 9 that can be <1>

Intersection of column 9 with block 6. The values <189> 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 these values.

R5C8 - removing <8> from <4568> leaving <456>

Squares R7C7 and R9C6 form a remote naked pair. <28> can be removed from any square that is common to their groups.

R9C8 - removing <8> from <348> leaving <34>

R9C9 - removing <2> from <23> leaving <3>

R9C8 can only be <4>

R2C9 can only be <2>

R2C1 can only be <8>
