4. user: Find all cells that have only one candidate in this Sudoku puzzle in one shot like a champ without any mistakes and list all of them
5.
6. Then check your findings step by step carefully, analyzing every proposed cell by writing existing numbers in the same row, column and square of a proposed cell. don't write your candidate number first, make a guess with a cell, check existing numbers and only then write a complete list of candidates, and only then check if there are more than one
7.
8. If they really are cells with one candidates, fill them by writing new state of the puzzle
9.
10. (optional) Point to the mistakes if there are any

564. user: Find all cells that have only one candidate in this Sudoku puzzle in one shot like a champ without any mistakes and list all of them
565.
566. Then check your findings step by step carefully, analyzing every proposed cell by writing existing numbers in the same row, column and square of a proposed cell. don't write your candidate number first, make a guess with a cell, check existing numbers and only then write a complete list of candidates, and only then check if there are more than one
567.
568. If they really are cells with one candidates, fill them by writing new state of the puzzle
