The fact that a certain row, column or square have a lot of empty spaces doesn’t mean that you can’t make progress there.When you begin to play Sudoku, you probably will have moments when you reach a roadblock. One of the common mistakes that the Sudoku beginners make is to focus too much on parts of the grid in which they had succeeded, while forgetting the empty parts. Sudoku is a momentum game, so it’s natural wanting to focus on the part of the grid in which you have already had success in the placement of the numbers. That leads us that the number 8 must go to the top right of the square (the 8 number marked in orange). If we look at the bottom row on the left and the central column above, we see the number 8 twice (enclosed in orange circles), which eliminates three spaces that can contain the number 8 (shown with orange X-s). After counting the existing numbers in the square we know that there are missing numbers: 1, 3, 5 and 8. A lot of information can be obtained, about which numbers can be excluded or added in the square, if you look at the nearby rows and columns which form the square.Īs an example in this grid, shown on the picture, there’s a square (below in the center, enclosed in orange), which has four empty spaces. The squares (there are 9 of them in the grid, in which square there are 9 spaces) it’s a wonderful place providing the ability to place numbers, because every square is consisted of other rows and columns. Whatever is the reason, many Sudoku beginners make the same mistake, because they don’t spend enough time checking the squares. Maybe it’s much easier for the Sudoku beginners to trace and count from 1 to 9 when they are placed in a row or column? However, many Sudoku players make the mistake of focusing only on certain rows or columns. Sudoku is a game where you should place the numbers from 1 to 9 in the empty spaces in a given row, column or square. That will make solving the puzzle easier.
Search for rows, columns and squares which already have many placed numbers. That’s why the Sudoku players should know: start by watching the easy accessible opportunities like this one. That’s an easy move for the Sudoku beginners, but there are people who are playing Sudoku for the first time and they are likely to miss this opportunity, while wasting time staring at other squares from the grid. We know that we have to place only one number on the empty space. Unfortunately most of the Sudoku beginners don’t know to find the easy options which are in front of them.įor an example, in the grid shown in this picture, we have a vertical column (the 4th column from left to right, enclosed in orange), which has 8 out of 9 numbers, that are already on the right places. The players should always scan the grid in searching of different opportunities, for placing a number in the empty spaces. Sudoku is a game of opportunity recognition.
Sudoku can be a fun and satisfying game in which you can spend hours playing, but it’s important to learn how to surpass the most common mistakes made by Sudoku beginners, so you can be confident in playing Sudoku for years.
