R4C5 is the only square in row 4 that can be <3>

R6C8 is the only square in row 6 that can be <3>

R7C3 is the only square in row 7 that can be <3>

R2C2 is the only square in row 2 that can be <3>

R3C4 is the only square in row 3 that can be <3>

R1C4 is the only square in block 2 that can be <1>

R1C2 can only be <4>

R1C1 can only be <2>

R1C5 is the only square in row 1 that can be <6>

R8C3 is the only square in column 3 that can be <2>

Squares R2C5 and R3C5 in column 5 form a simple naked pair. These 2 squares both contain the 2 possibilities <27>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R5C5 - removing <7> from <5789> leaving <589>

R6C5 - removing <2> from <259> leaving <59>

R7C5 - removing <2> from <2459> leaving <459>

R9C5 - removing <7> from <4789> leaving <489>

R7C4 is the only square in row 7 that can be <2>

Intersection of row 2 with block 3. The values <45> only appears in one or more of squares R2C7, R2C8 and R2C9 of row 2. These squares are the ones that intersect with block 3. Thus, the other (non-intersecting) squares of block 3 cannot contain these values.

R3C7 - removing <5> from <257> leaving <27>

R3C9 - removing <5> from <12578> leaving <1278>

Squares R3C5 and R3C7 in row 3 form a simple naked pair. These 2 squares both contain the 2 possibilities <27>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R3C3 - removing <7> from <1789> leaving <189>

R3C9 - removing <27> from <1278> leaving <18>

Intersection of column 3 with block 4. The values <46> only appears in one or more of squares R4C3, R5C3 and R6C3 of column 3. These squares are the ones that intersect with block 4. Thus, the other (non-intersecting) squares of block 4 cannot contain these values.

R4C2 - removing <6> from <569> leaving <59>

Squares R4C1 and R4C2 in row 4 form a simple naked pair. These 2 squares both contain the 2 possibilities <59>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R4C3 - removing <9> from <69> leaving <6>

R4C7 - removing <5> from <2567> leaving <267>

R4C9 - removing <59> from <256789> leaving <2678>

Squares R3C7 and R4C7 in column 7 form a simple naked pair. These 2 squares both contain the 2 possibilities <27>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R2C7 - removing <27> from <2457> leaving <45>

R5C7 - removing <7> from <4567> leaving <456>

R6C7 - removing <2> from <2456> leaving <456>

Squares R4C1 and R4C2 in block 4 form a simple naked pair. These 2 squares both contain the 2 possibilities <59>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the block.

R5C3 - removing <9> from <149> leaving <14>

R6C3 - removing <9> from <149> leaving <14>
