R1C6 can only be <9>

R5C5 can only be <7>

R6C1 can only be <5>

R6C5 can only be <9>

R4C1 can only be <4>

R4C5 can only be <8>

R4C4 is the only square in row 4 that can be <5>

R6C6 is the only square in row 6 that can be <2>

R9C2 is the only square in row 9 that can be <2>

R1C8 is the only square in row 1 that can be <2>

R1C2 is the only square in row 1 that can be <5>

R3C2 can only be <7>

R2C3 is the only square in row 2 that can be <2>

Squares R9C4 and R9C6 in row 9 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 row.

R9C1 - removing <6> from <168> leaving <18>

R9C8 - removing <36> from <1367> leaving <17>

R9C9 - removing <36> from <13678> leaving <178>

Squares R1C1 and R9C1 in column 1 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.

R2C1 - removing <8> from <689> leaving <69>

R8C1 - removing <8> from <689> leaving <69>

Squares R5C7 and R7C7 in column 7 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.

R2C7 - removing <6> from <468> leaving <48>

R3C7 - removing <16> from <156> leaving <5>

R8C7 - removing <6> from <4568> leaving <458>

R8C8 is the only square in row 8 that can be <5>

R7C8 is the only square in column 8 that can be <3>

R8C3 is the only square in row 8 that can be <3>

Intersection of column 8 with block 3. The value <6> only appears in one or more of squares R1C8, R2C8 and R3C8 of column 8. These squares are the ones that intersect with block 3. Thus, the other (non-intersecting) squares of block 3 cannot contain this value.

R2C9 - removing <6> from <4678> leaving <478>

Squares R1C1 and R1C9 in row 1 and R9C1 and R9C9 in row 9 form a Simple X-Wing pattern on possibility <8>. All other instances of this possibility in columns 1 and 9 can be removed.

R2C9 - removing <8> from <478> leaving <47>

R8C9 - removing <8> from <468> leaving <46>

Squares R3C8 and R7C7 form a remote naked pair. <16> can be removed from any square that is common to their groups.

R9C8 - removing <1> from <17> leaving <7>

R2C8 can only be <6>

R2C1 can only be <9>
