R4C2 is the only square in row 4 that can be <6>

R4C5 is the only square in row 4 that can be <9>

R4C1 is the only square in row 4 that can be <5>

R5C9 is the only square in row 5 that can be <3>

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

R5C1 is the only square in row 5 that can be <7>

R6C1 can only be <2>

R6C2 can only be <3>

R6C9 can only be <4>

R3C1 can only be <1>

R6C5 can only be <5>

R6C8 can only be <7>

R7C1 can only be <8>

R7C2 is the only square in column 2 that can be <1>

R9C2 is the only square in column 2 that can be <7>

Squares R2C5 and R2C7 in row 2 form a simple naked pair. These 2 squares both contain the 2 possibilities <46>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R2C4 - removing <46> from <24569> leaving <259>

R2C6 - removing <4> from <2459> leaving <259>

Squares R7C3 and R8C3 in column 3 form a simple naked pair. These 2 squares both contain the 2 possibilities <35>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the column.

R2C3 - removing <5> from <259> leaving <29>

R3C3 - removing <5> from <259> leaving <29>

Intersection of row 2 with block 2. The value <5> only appears in one or more of squares R2C4, R2C5 and R2C6 of row 2. These squares are the ones that intersect with block 2. Thus, the other (non-intersecting) squares of block 2 cannot contain this value.

R1C4 - removing <5> from <145> leaving <14>

R1C6 - removing <5> from <1458> leaving <148>

R3C4 - removing <5> from <245679> leaving <24679>

R3C6 - removing <5> from <24589> leaving <2489>

Squares R1C6 and R1C8 in row 1 and R9C6 and R9C8 in row 9 form a Simple X-Wing pattern on possibility <8>. All other instances of this possibility in columns 6 and 8 can be removed.

R3C6 - removing <8> from <2489> leaving <249>

R4C8 - removing <8> from <28> leaving <2>

R8C6 - removing <8> from <1358> leaving <135>

R4C9 can only be <8>

R3C9 can only be <5>

R3C2 can only be <4>

R7C9 can only be <2>

R1C2 can only be <5>

Squares R3C3 and R3C6 in row 3 form a simple naked pair. These 2 squares both contain the 2 possibilities <29>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R3C4 - removing <29> from <2679> leaving <67>

Squares R3C3, R3C6, R2C3 and R2C6 form a Type-1 Unique Rectangle on <29>.

R2C6 - removing <29> from <259> leaving <5>

Squares R3C7 (XY), R3C4 (XZ) and R8C7 (YZ) form an XY-Wing pattern on <7>. All squares that are buddies of both the XZ and YZ squares cannot be <7>.

R8C4 - removing <7> from <157> leaving <15>

Squares R1C4<14>, R8C4<15> and R9C4<45> in column 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 column.

R5C4 - removing <14> from <124> leaving <2>

R7C4 - removing <45> from <45679> leaving <679>

R2C4 can only be <9>

R2C3 can only be <2>

R3C6 can only be <2>

R3C3 can only be <9>

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

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

R8C3 can only be <5>

R8C4 can only be <1>

R8C6 can only be <3>

R1C4 can only be <4>

R1C8 can only be <8>
