R3C4 is the only square in column 4 that can be <5>

R8C7 is the only square in column 7 that can be <1>

R3C7 is the only square in column 7 that can be <6>

R3C1 is the only square in row 3 that can be <8>

R2C3 can only be <7>

R1C3 can only be <6>

R3C8 is the only square in row 3 that can be <2>

R1C1 is the only square in row 1 that can be <2>

R7C2 is the only square in row 7 that can be <6>

R4C2 is the only square in column 2 that can be <7>

R1C8 is the only square in column 8 that can be <7>

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

Squares R5C2 and R6C1 in block 4 form a simple naked pair. These 2 squares both contain the 2 possibilities <14>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R4C1 - removing <1> from <136> leaving <36>

R5C1 - removing <14> from <1346> leaving <36>

Squares R4C1 and R5C1 in column 1 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.

R8C1 - removing <3> from <349> leaving <49>

Intersection of row 4 with block 5. The value <1> 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.

R5C4 - removing <1> from <1249> leaving <249>

R5C5 - removing <1> from <123489> leaving <23489>

R5C6 - removing <1> from <13489> leaving <3489>

R6C5 - removing <1> from <1247> leaving <247>

R6C6 - removing <1> from <147> leaving <47>

Intersection of row 7 with block 8. The values <14> only appears in one or more of squares R7C4, R7C5 and R7C6 of row 7. These squares are the ones that intersect with block 8. Thus, the other (non-intersecting) squares of block 8 cannot contain these values.

R8C6 - removing <4> from <3489> leaving <389>

R9C4 - removing <4> from <249> leaving <29>

R9C5 - removing <4> from <23489> leaving <2389>

Squares R2C7, R2C9, R9C7 and R9C9 form a Type-1 Unique Rectangle on <58>.

R9C9 - removing <58> from <458> leaving <4>
