R4C4 can only be <1>

R6C7 can only be <1>

R4C6 can only be <5>

R4C7 can only be <4>

R5C5 can only be <9>

R6C6 can only be <7>

R4C3 can only be <3>

R6C4 can only be <2>

R7C6 can only be <1>

R6C3 can only be <5>

R5C8 can only be <2>

R5C9 can only be <6>

R3C6 can only be <9>

R2C1 is the only square in row 2 that can be <2>

R2C3 is the only square in row 2 that can be <8>

R3C2 is the only square in row 3 that can be <5>

R1C9 is the only square in row 1 that can be <5>

R9C5 is the only square in row 9 that can be <5>

R8C9 is the only square in column 9 that can be <4>

Squares R3C4 and R3C7 in row 3 form a simple naked pair. These 2 squares both contain the 2 possibilities <37>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R3C8 - removing <37> from <1347> leaving <14>

Squares R7C4 and R7C8 in row 7 form a simple naked pair. These 2 squares both contain the 2 possibilities <37>. Since each of the squares must contain one of the possibilities, they can be eliminated from the other squares in the row.

R7C2 - removing <7> from <479> leaving <49>

R7C7 - removing <37> from <3679> leaving <69>

Intersection of row 8 with block 7. The value <1> only appears in one or more of squares R8C1, R8C2 and R8C3 of row 8. These squares are the ones that intersect with block 7. Thus, the other (non-intersecting) squares of block 7 cannot contain this value.

R9C1 - removing <1> from <137> leaving <37>

R9C2 - removing <1> from <179> leaving <79>

Intersection of block 1 with row 1. The value <7> only appears in one or more of squares R1C1, R1C2 and R1C3 of block 1. These squares are the ones that intersect with row 1. Thus, the other (non-intersecting) squares of row 1 cannot contain this value.

R1C5 - removing <7> from <137> leaving <13>

R1C8 - removing <7> from <1347> leaving <134>

Intersection of column 8 with block 9. The value <7> 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.

R8C7 - removing <7> from <367> leaving <36>

Squares R3C7 and R8C5 form a remote naked pair. <37> can be removed from any square that is common to their groups.

R8C7 - removing <3> from <36> leaving <6>

R8C3 can only be <1>

R7C7 can only be <9>

R7C2 can only be <4>

R2C7 can only be <7>

R9C9 can only be <1>

R3C3 can only be <4>

R2C9 can only be <9>
