Reasoning 



R8C4 can only be <1>

R1C2 is the only square in row 1 that can be <2>

R1C5 is the only square in row 1 that can be <9>

R2C9 is the only square in row 2 that can be <5>

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

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

R6C6 is the only square in row 6 that can be <1>

R8C1 is the only square in row 8 that can be <4>

R4C2 is the only square in column 2 that can be <4>

R4C7 is the only square in row 4 that can be <9>

R6C2 is the only square in row 6 that can be <9>

R9C2 can only be <3>

R3C4 is the only square in column 4 that can be <4>

R2C6 is the only square in column 6 that can be <2>

R6C4 is the only square in column 4 that can be <2>

R6C7 can only be <7>

Squares R5C1 and R5C5 in row 5 form a simple naked pair. These 2 squares both contain the 2 possibilities <67>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R5C9 - removing <6> from <246> leaving <24>

Squares R4C8 and R6C8 in column 8 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.

R1C8 - removing <3> from <137> leaving <17>

R9C8 - removing <6> from <167> leaving <17>

Intersection of column 1 with block 1. The value <3> only appears in one or more of squares R1C1, R2C1 and R3C1 of column 1. These squares are the ones that intersect with block 1. Thus, the other (non-intersecting) squares of block 1 cannot contain this value.

R1C3 - removing <3> from <378> leaving <78>

Squares R6C3, R6C8, R4C3 and R4C8 form a Type-1 Unique Rectangle on <36>.

R4C3 - removing <36> from <367> leaving <7>
