R3C8 is the only square in row 3 that can be <5>

R1C9 can only be <2>

R1C5 can only be <6>

R1C1 can only be <5>

R3C5 is the only square in row 3 that can be <8>

R5C8 is the only square in row 5 that can be <6>

R5C1 is the only square in row 5 that can be <3>

R4C8 is the only square in row 4 that can be <3>

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

R2C2 can only be <8>

R2C1 can only be <6>

R8C5 is the only square in row 8 that can be <4>

R8C9 is the only square in row 8 that can be <5>

Squares R5C3 and R5C7 in row 5 form a simple naked pair. These 2 squares both contain the 2 possibilities <78>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R5C2 - removing <7> from <1257> leaving <125>

R5C5 - removing <7> from <2579> leaving <259>

R5C9 - removing <78> from <14789> leaving <149>

Squares R7C3 and R7C7 in row 7 form a simple naked pair. These 2 squares both contain the 2 possibilities <78>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R7C8 - removing <7> from <179> leaving <19>

Intersection of row 6 with block 6. The value <4> only appears in one or more of squares R6C7, R6C8 and R6C9 of row 6. These squares are the ones that intersect with block 6. Thus, the other (non-intersecting) squares of block 6 cannot contain this value.

R5C9 - removing <4> from <149> leaving <19>

Intersection of column 8 with block 9. The value <1> only appears in one or more of squares R7C8, R8C8 and R9C8 of column 8. These squares are the ones that intersect with block 9. Thus, the other (non-intersecting) squares of block 9 cannot contain this value.

R9C9 - removing <1> from <189> leaving <89>

Squares R2C8, R2C9, R6C8 and R6C9 form a Type-3 Unique Rectangle on <47>. Upon close inspection, it is clear that:

(R6C8 or R6C9)<89> and R6C1<89> form a naked pair on <89> in row 6. No other squares in the row can contain these possibilities

R6C5 - removing <9> from <579> leaving <57>

Squares R6C2 and R6C5 in row 6 form a simple naked pair. These 2 squares both contain the 2 possibilities <57>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R6C8 - removing <7> from <479> leaving <49>

R6C9 - removing <7> from <4789> leaving <489>

Squares R3C4, R3C6, R5C4 and R5C6 form a Type-4 Unique Rectangle on <24>.

R5C4 - removing <2> from <249> leaving <49>

R5C6 - removing <2> from <245> leaving <45>

Intersection of block 5 with column 5. The values <27> only appears in one or more of squares R4C5, R5C5 and R6C5 of block 5. These squares are the ones that intersect with column 5. Thus, the other (non-intersecting) squares of column 5 cannot contain these values.

R7C5 - removing <2> from <1259> leaving <159>

Squares R6C9 (XYZ), R6C8 (XZ) and R9C9 (YZ) form an XYZ-Wing pattern on <9>. All squares that are buddies of all three squares cannot be <9>.

R4C9 - removing <9> from <179> leaving <17>

R5C9 - removing <9> from <19> leaving <1>

R4C9 can only be <7>

R2C9 can only be <4>

R5C7 can only be <8>
