Reasoning 



R5C5 can only be <3>

R8C8 can only be <8>

R4C8 can only be <1>

R5C3 is the only square in row 5 that can be <1>

Squares R2C6 and R2C8 in row 2 form a simple naked pair. These 2 squares both contain the 2 possibilities <25>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R2C4 - removing <5> from <4579> leaving <479>

R2C5 - removing <2> from <2479> leaving <479>

Squares R2C2 and R8C2 in column 2 form a simple naked pair. These 2 squares both contain the 2 possibilities <79>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R4C2 - removing <79> from <3679> leaving <36>

R5C2 - removing <7> from <267> leaving <26>

R6C2 - removing <9> from <239> leaving <23>

Intersection of column 1 with block 4. The values <89> only appears in one or more of squares R4C1, R5C1 and R6C1 of column 1. These squares are the ones that intersect with block 4. Thus, the other (non-intersecting) squares of block 4 cannot contain these values.

R4C3 - removing <9> from <79> leaving <7>

R6C3 - removing <9> from <459> leaving <45>

Squares R5C1 and R6C3 in block 4 form a simple naked pair. These 2 squares both contain the 2 possibilities <45>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R6C1 - removing <45> from <4589> leaving <89>

Squares R9C1<47>, R9C5<247> and R9C9<27> in row 9 form a comprehensive naked triplet. These 3 squares can only contain the 3 possibilities <247>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R9C4 - removing <47> from <1457> leaving <15>

R9C6 - removing <2> from <125> leaving <15>

Squares R3C3<59>, R3C4<359> and R3C7<35> in row 3 form a comprehensive naked triplet. These 3 squares can only contain the 3 possibilities <359>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R3C5 - removing <9> from <689> leaving <68>

R3C6 - removing <35> from <3568> leaving <68>

Squares R9C4, R9C6, R1C4 and R1C6 form a Type-3 Unique Rectangle on <15>. Upon close inspection, it is clear that:

(R1C4 or R1C6)<237>, R1C9<23> and R1C5<27> form a naked triplet on <237> in row 1. No other squares in the row can contain these possibilities

R1C1 - removing <7> from <57> leaving <5>
