R1C3 can only be <2>

R2C3 can only be <5>

R3C3 can only be <4>

R4C3 can only be <3>

R9C3 can only be <1>

R9C7 can only be <7>

R1C2 is the only square in row 1 that can be <7>

R4C1 is the only square in row 4 that can be <7>

R7C6 is the only square in row 7 that can be <9>

R9C6 is the only square in row 9 that can be <2>

R8C8 is the only square in column 8 that can be <4>

Squares R2C1 and R2C2 in row 2 form a simple naked pair. These 2 squares both contain the 2 possibilities <68>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R2C5 - removing <8> from <128> leaving <12>

R2C6 - removing <8> from <138> leaving <13>

R2C8 - removing <6> from <1236> leaving <123>

Squares R5C1 and R7C1 in column 1 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.

R9C1 - removing <5> from <568> leaving <68>

Squares R7C7 and R8C7 in column 7 form a simple naked pair. These 2 squares both contain the 2 possibilities <13>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R1C7 - removing <1> from <189> leaving <89>

R6C7 - removing <3> from <389> leaving <89>

Squares R7C7 and R8C7 in block 9 form a simple naked pair. These 2 squares both contain the 2 possibilities <13>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R8C9 - removing <13> from <1356> leaving <56>

Intersection of row 4 with block 5. The value <8> only appears in one or more of squares R4C4, R4C5 and R4C6 of row 4. These squares are the ones that intersect with block 5. Thus, the other (non-intersecting) squares of block 5 cannot contain this value.

R6C4 - removing <8> from <2358> leaving <235>

R6C5 - removing <8> from <2489> leaving <249>

R6C6 - removing <8> from <358> leaving <35>

Intersection of row 5 with block 6. The value <3> only appears in one or more of squares R5C7, R5C8 and R5C9 of row 5. These squares are the ones that intersect with block 6. Thus, the other (non-intersecting) squares of block 6 cannot contain this value.

R6C9 - removing <3> from <358> leaving <58>

Intersection of row 9 with block 7. The value <8> only appears in one or more of squares R9C1, R9C2 and R9C3 of row 9. These squares are the ones that intersect with block 7. Thus, the other (non-intersecting) squares of block 7 cannot contain this value.

R8C2 - removing <8> from <3568> leaving <356>

Intersection of column 6 with block 5. The value <5> only appears in one or more of squares R4C6, R5C6 and R6C6 of column 6. These squares are the ones that intersect with block 5. Thus, the other (non-intersecting) squares of block 5 cannot contain this value.

R4C4 - removing <5> from <158> leaving <18>

R6C4 - removing <5> from <235> leaving <23>

Squares R4C4<18>, R7C4<15> and R8C4<158> in column 4 form a comprehensive naked triplet. These 3 squares can only contain the 3 possibilities <158>. 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 <168> leaving <6>

R3C4 - removing <8> from <2368> leaving <236>

R3C6 is the only square in block 2 that can be <8>

Intersection of row 1 with block 3. The values <189> 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.

R2C8 - removing <1> from <123> leaving <23>

Squares R2C1, R2C2, R9C1 and R9C2 form a Type-1 Unique Rectangle on <68>.

R9C2 - removing <68> from <568> leaving <5>
