Tips for solving Sudoku

Know where to start solving

If you’re new to playing Sudoku, you might find you don’t know where to start whenever you first look at a new puzzle. 

Sometimes placing the first digit in the grid can be the hardest part. 

To make it easier, there are certain things you’ll want to look for. There are also certain things you don’t want to do. 

The first tip is to look for rows, columns or the 3×3 blocks where there are more given digits. 

These areas with more given digits will constrain the other empty cells within the same row, column or block. Meaning that there’ll be fewer possibilities for what values these cells can contain than for other empty cells. 

Related to this, another trick is to look at which numbers appear more among the given digits. 

For example, if you have a new Sudoku puzzle with five 9s already given and no 2s, then placing one of the four remaining 9s into the grid will usually be easier than placing one of the nine 2s.  

Look for single candidates 

Single candidates, also known as naked singles, occur when a particular cell can only has one possible candidate.  

This will be because all the other digits from 1 to 9 will have been ruled out by other numbers in the grid. 

If you look at the Sudoku puzzle below, you’ll notice that cell row 7, column 5 only has a single candidate – 1. 

This is because all the other numbers from 2 to 9 appear in either the same row, column or in the 3×3 block.
