R3C9 is the only square in row 3 that can be <3>

R2C6 is the only square in row 2 that can be <3>

R4C2 is the only square in row 4 that can be <3>

R6C5 is the only square in row 6 that can be <9>

R8C9 is the only square in row 8 that can be <6>

R9C3 is the only square in row 9 that can be <2>

R5C5 is the only square in column 5 that can be <6>

R5C4 is the only square in row 5 that can be <5>

R4C1 is the only square in row 4 that can be <5>

R6C8 is the only square in row 6 that can be <5>

R1C7 is the only square in row 1 that can be <5>

R7C5 is the only square in row 7 that can be <5>

R8C2 is the only square in row 8 that can be <5>

Squares R8C4 and R9C4 in column 4 form a simple naked pair. These 2 squares both contain the 2 possibilities <18>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R1C4 - removing <18> from <1678> leaving <67>

R2C4 - removing <1> from <167> leaving <67>

Squares R1C6 and R5C6 in column 6 form a simple naked pair. These 2 squares both contain the 2 possibilities <18>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R8C6 - removing <18> from <1489> leaving <49>

R9C6 - removing <18> from <1489> leaving <49>

Squares R4C9 and R6C9 in column 9 form a simple naked pair. These 2 squares both contain the 2 possibilities <18>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R2C9 - removing <1> from <179> leaving <79>

R7C9 - removing <1> from <179> leaving <79>

Squares R1C3<189>, R1C6<18> and R1C8<19> in row 1 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 row.

R1C2 - removing <1> from <167> leaving <67>

Squares R1C3 and R1C6 in row 1 and R5C3 and R5C6 in row 5 form a Simple X-Wing pattern on possibility <8>. All other instances of this possibility in columns 3 and 6 can be removed.

R3C3 - removing <8> from <148> leaving <14>

Squares R3C5 and R5C3 form a remote naked pair. <18> can be removed from any square that is common to their groups.

R3C3 - removing <1> from <14> leaving <4>

R2C8 is the only square in row 2 that can be <4>

Intersection of row 2 with block 1. The value <1> only appears in one or more of squares R2C1, R2C2 and R2C3 of row 2. 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 <1> from <189> leaving <89>

R3C1 - removing <1> from <178> leaving <78>

Squares R1C2, R1C4, R2C2 and R2C4 form a Type-1 Unique Rectangle on <67>.

R2C2 - removing <67> from <167> leaving <1>

R6C2 can only be <4>

R9C2 can only be <7>

R1C2 can only be <6>

R1C4 can only be <7>

R2C4 can only be <6>

Squares R8C4, R9C4, R8C8 and R9C8 form a Type-2 Unique Rectangle on <18>.

R1C8 - removing <9> from <19> leaving <1>

R7C9 - removing <9> from <79> leaving <7>

R1C6 can only be <8>

R3C7 can only be <7>

R3C1 can only be <8>

R2C9 can only be <9>

R1C3 can only be <9>
