The Naked Single Method

The Naked Single method involves finding cells with only one possible number that can be filled in. It's a great way to start solving easy and medium level puzzles.

To identify Naked Singles, you need to look for cells with only one possible number. These numbers are called "naked" because they are not hidden by other numbers. If a cell has only one possible number left, it is considered a Naked Single.

In this example, we can see that the yellow cell only has the number 8 as a possible value. If you put the number 2, 5, 7, 4, or 1 in the yellow cell, it would create a conflict with the rules of Sudoku, as these numbers already appear in the same column. Numbers 9, 6, and 3 already appear in the same row. Numbers 6 and 7 already appear in the same .

The Naked Single technique is easy to apply and considered the simplest way to solve Sudoku puzzles. It's a great way to build your confidence and skills in solving Sudoku puzzles. However, it may not be enough to solve more difficult and advanced puzzles.

In conclusion, if you're new to Sudoku, the Naked Single method is a great place to start. It's easy to apply and will help you solve puzzles more efficiently.
