![]() Then you can come back to the more difficult areas later. That’s why it’s important to learn how to shift your focus around the grid to identify which area can be worked on first. ![]() If you’re doing this, then it likely means that the part of the grid you’re focusing on requires you to place digits elsewhere in the grid before you can resolve it. 4) Don’t focus too long in the one placeĮffective scanning also means that you don’t spend too long looking at one part of the grid. Taking this tip a step further, when you feel confident, you’ll also want to scan a couple of areas at the one time to see how they interact.įor example, if you scan along a row and a column and notice that together they contain a large number of digits, then you’ll immediately know that the cell where they intersect will be heavily constrained. This way you’ll be able to identify which areas are easier so that you can tackle them first. Instead, it’s better to scan different rows, columns and 3×3 blocks one at a time. 3) Work on your scanning techniquesĭon’t try to focus on the entire Sudoku grid at the one time. This also shows the importance of the previous tip of starting in areas with plenty of given digits. This is because all the other numbers from 2 to 9 appear in either the same row, column or in the 3×3 block. If you look at the Sudoku puzzle below, you’ll notice that cell row 7, column 5 only has a single candidate – 1. This will be because all the other digits from 1 to 9 will have been ruled out by other numbers in the grid. Single candidates, also known as naked singles, occur when a particular cell can only has one possible candidate. Related to this, another trick is to look at which numbers appear more among the given digits.įor 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. Meaning that there’ll be fewer possibilities for what values these cells can contain than for other empty cells. These areas with more given digits will constrain the other empty cells within the same row, column or block. The first tip is to look for rows, columns or the 3×3 blocks where there are more given digits. There are also certain things you don’t want to do. To make it easier, there are certain things you’ll want to look for. Sometimes placing the first digit in the grid can be the hardest part. ![]() 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.
