What is Sudoku?
Sudoku is a puzzle in which each participant enters the numbers one through nine into squares. With a subdivision into nine smaller squares in such a way that every number appears once in a horizontal line, vertical line, and square.
In Sudoku, you aim to fill a 9×9 grid with numbers in each column, row, and all nine 33 grids that are part of the bigger 9×9 grid, including all digits from 1 to 9. This game may have already turned off non-puzzle lovers. But, in any case, this game engages your brain. Now let us see by playing on the app, How To Solve Sudoku When Stuck by learning the following techniques.
Strategies to use if you are stuck playing Sudoku
Using these approaches, you can solve practically any Sudoku puzzle.
Sole Candidate
This occurs when a particular cell contains a single number. When all other digits, save the prospective candidate, fall within the current row, column, or box, it is a single candidate (naked single). 
Only one option remains when all options are removed after scanning: the correct value.
Unique Candidate
The single candidate/hidden single applies to Sudoku’s one rule, which states that each box, row, and column must have digits 1 to 9 without repetition. 
So, it’s perfect if a specific digit fits in a row, column, or box.
Naked Subset
This approach applies to cells that contain only a limited number of candidates. When the remaining candidates have been placed, you can efficiently identify bare subgroups (pair/ triplet/ quad). 
If two cells in a row, column, or box have the same two candidates, they can be eliminated from the cells in another row, column, or box.
Hidden Subset
Instead of influencing cells in other rows, columns, and boxes, concealed subset affects the same subgroup’s pair/ triplet/ quad. 
If you utilize computer assistance to generate a complete candidate list for all cells, they are the ones with specified numbers buried amid other candidates for that cells.
X-Wing
This technique cooperates with cells that form a rectangle and happens in uncommon cases. 
X-Wing is a pattern that spans many columns and rows, claiming candidates from other related rows and columns.
Swordfish
Swordfish is a more advanced version of X-Wing. However, it is a master approach for complex tasks. Rows cannot include more than three possibilities, whereas columns can. 
In this method, you can eliminate all candidates in the column and save those who form a swordfish. It also works the other way around.
Forcing Chains
This one is more difficult to use, but it shows precisely what number a specific cell would store. It enables you to search for cells with exactly two integers as candidates. Whatever value you choose for one cell, the other must have a different value.
So that’s all there is to it! It’s time to start putting these Sudoku problem-solving tactics into practice on sites like Solitaire, where you may play infinite Sudoku games of varying difficulty levels to hone your skills. Focus on perfecting one approach before moving on to the next in each match. They will soon become second nature to you.
There are more complicated and intricate tactics, such as XYZ-Wing, 3D Medusa, and X-Cycles, but that’s another topic.
The ones listed above are basic to intermediate Sudoku-solving approaches, particularly for solving a puzzle that has stumped you.
6 ActionableTips for Playing Sudoku
Sudoku has basic rules. A 9×9 square has to be there with numbers from 1 to 9, with no repeated numbers in each horizontal or vertical line. The grid has 3×3 squares with no repetition numbers to make things even more complex.
The puzzles will assist you in getting started by supplying some accurate numbers – the fewer numbers offered, the more complex the puzzle.
Here are a few pointers to help novices solve sudoku puzzles:
Look for Simple Solutions
Many puzzles will include one or two blank lines or boxes. A line may lack a five and a 6, but a box along that line would already have a 6, indicating that this blank must be a five while the other blank must be a 6. One or two numbers missing in the smaller spaces are the same. Filling in the blanks can start you on the path to a solution.
Look for the Missing Figures
As you finish the simple solutions, there are more missing numbers that are simple to put in. In the preceding example, the box now has a 5, which may help you resolve the 3×3 area or the lines that cross it.
Keep Scanning the Entire Puzzle
If you are stuck, try not to focus too much on one section of the grid. Allow your eyes to scan the problem for a new location on the grid with new choices. You can discover another quick solution.
Re-evaluate the grid continually.
Check if adding a new number opens up a new row or box. It could limit the possibilities or highlight another number. You may find it more quickly if you continuously ask yourself what numbers are missing in a line or grid.
Be patient and have fun while hunting
Remember that while you want to complete a puzzle that you downloaded from the App Store, the goal is to appreciate the challenge and engage your brain while relaxing. If you feel yourself becoming frustrated, take a break. Allow your mind to clear before attempting again. The essential thing is to have a good time.

Don’t concentrate on one thing for too long.
Effective scanning also implies that you do not spend too much time looking at one grid section.
If you’re doing this, the section of the grid you’re working on requires you to insert numbers from elsewhere in the grid before you can solve it.
That is why it is critical to understand how to shift your focus around the grid to choose which area may be worked on first. Then you can return to the more challenging portions at a later time.
