R2C5 is the only square in row 2 that can be <6>

R3C5 is the only square in row 3 that can be <9>

R8C5 is the only square in row 8 that can be <3>

R1C6 is the only square in row 1 that can be <3>

R1C5 is the only square in block 2 that can be <2>

R1C1 is the only square in row 1 that can be <7>

Squares R1C8 and R4C8 in column 8 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 column.

R6C8 - removing <5> from <568> leaving <68>

R8C8 - removing <5> from <568> leaving <68>

Squares R8C1 and R9C2 in block 7 form a simple naked pair. These 2 squares both contain the 2 possibilities <26>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R8C3 - removing <2> from <278> leaving <78>

R9C1 - removing <26> from <269> leaving <9>

R9C3 - removing <2> from <2789> leaving <789>

Intersection of row 1 with block 3. The values <145> only appears in one or more of squares R1C7, R1C8 and R1C9 of row 1. These squares are the ones that intersect with block 3. Thus, the other (non-intersecting) squares of block 3 cannot contain these values.

R2C7 - removing <1> from <189> leaving <89>

R2C9 - removing <14> from <1489> leaving <89>

Intersection of column 1 with block 1. The value <1> 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.

R2C2 - removing <1> from <123> leaving <23>

Intersection of column 9 with block 9. The value <2> only appears in one or more of squares R7C9, R8C9 and R9C9 of column 9. These squares are the ones that intersect with block 9. Thus, the other (non-intersecting) squares of block 9 cannot contain this value.

R7C7 - removing <2> from <2678> leaving <678>

R8C7 - removing <2> from <125678> leaving <15678>

Squares R4C4<14>, R4C5<145> and R4C8<45> in row 4 form a comprehensive naked triplet. These 3 squares can only contain the 3 possibilities <145>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R4C2 - removing <1> from <123> leaving <23>

R4C3 - removing <5> from <2359> leaving <239>

R4C7 - removing <5> from <259> leaving <29>

R6C2 is the only square in column 2 that can be <1>

R8C1 can only be <2>

R2C1 can only be <1>

R2C6 can only be <4>

R3C1 can only be <5>

R3C3 can only be <4>

R5C1 can only be <6>

R3C6 is the only square in column 6 that can be <1>

R3C4 can only be <7>

Squares R2C2, R2C3, R4C2 and R4C3 form a Type-1 Unique Rectangle on <23>.

R4C3 - removing <23> from <239> leaving <9>

R4C7 can only be <2>

R5C3 can only be <5>

R4C2 can only be <3>

R6C3 can only be <2>

R2C3 can only be <3>

R2C2 can only be <2>

Squares R2C7 and R5C7 in column 7 form a simple naked pair. These 2 squares both contain the 2 possibilities <89>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R6C7 - removing <8> from <568> leaving <56>

R7C7 - removing <8> from <678> leaving <67>

R8C7 - removing <8> from <15678> leaving <1567>
