By Naked Singles Approach for How To Solve Sudoku Puzzles we get value of the Cell (5,3) as 1. By Reduction Approach for How To Solve Sudoku Puzzles we get the values of the Cells (4,1) and (5,1) as '4' and '3' respectively. Consequently we get the values of the Cells (9,5), (8,5) and (7,5) as '7 , '8' and '3’ respectively by Reduction Approach for How To Solve Sudoku Puzzles

Finally by Reduction Approach for How To Solve Sudoku Puzzles, we get the values of the Cells (4,2), (4,5), (4,7), (4,8), (5,2), (5,5), (5,7) and (5,8) as '6' , '9' , '2' , '1' , '2' , '6', '4' and '9' respectively.

So, we have been able to solve this Sudoku puzzle using 6 different

Approach for How To Solve Sudoku Puzzleses namely, Naked Singles, Hidden Singles, Direct Interaction,

Naked Subsets, Hidden Subsets and Reduction Approach for How To Solve Sudoku Puzzleses.

Let's try to solve this puzzle also by using as many methods as we can. In this puzzle, we will also try to employ some new method methods that we have not used till now.

Let's try to begin solving the puzzle with the easier Approach for How To Solve Sudoku Puzzleses.

Cell (9,2) should take the value '1' by the Hidden Singles Approach for How To Solve Sudoku Puzzles

considering the '1's in C1 & C3. Cell (8,3) should be '4' by the Naked

Singles Approach for How To Solve Sudoku Puzzles. Let us assign these values to their respective Cells.

Now, we can find the value of Cell (7,9) as '4' by the Hidden Singles

Approach for How To Solve Sudoku Puzzles considering '4's in C7, C8 & R8.

Similarly, we can find the value of the Cell (7,8) as '5' considering R8, R9 & C7. Let us assign these values to their respective Cells. And by the

Naked Singles Approach for How To Solve Sudoku Puzzles, we can fill the values of Cell (9,1) and (8,1) as '9' and '6' respectively.

Now, we can find the value of Cell (1,9) as '5' by the Hidden Singles

Approach for How To Solve Sudoku Puzzles, considering R2 & C8. By the Naked Singles Approach for How To Solve Sudoku Puzzles, we get the value of the Cell (1,8) as '9' and similarly Cell (3,3) takes the

value '2'.

After assigning the above values to their respective Cells, we can find the values of the Cells (2,7) & (2,9) as '2' & '6' respectively by the 

Naked Singles Approach for How To Solve Sudoku Puzzles. Let's now consider the possible values in C2.

Now, Cells (1,2) & (6,2) of C2 have the same set of possible values viz.,

'3' & '4'. By the Naked Subsets Approach for How To Solve Sudoku Puzzles, we can eliminate '3' & '4' in

the possible Cells of C2.

Let's now consider the Bottom Right Major Square for the possible

values in its Cells.
