## What is Sudoku?

**Sudoku**, sometimes spelled **Su Doku**, is a number puzzle with a square grid of **n ^{2}** cells that are segmented into

**n**rows and n columns. The size of the grid is typically

**9×9**, but sizes as small as

**4×4**and as large as

**25×25**have been published. The puzzle begins with n givens filled in along with constraints that specified n unique numbers must be placed in each row, column, and internal square without duplicating the number. The difficulty arises as the givens are removed or random numbers added, particularly when some numbers are serially linked.

Thus at the core of being able to get unstuck from a Sudoku board is both memorizing and creatively using **Sudoku solving techniques**, to reduce the tilting blockages represented by the sticky puzzle pieces that prevent forward progress.

### How to Play Sudoku?

Sudoku is played on a **9 x 9** grid and is a game of logic in which you need to enter the numbers **1 to 9** such that all numbers appear only once in every **row**, every **column**, and every ** 3 x 3** unit. The conventional Sudoku rules mandate that all cells of the grid have preliminary digits provided, but so long as all rules are satisfied, the numbers could be replaced by colors, letters, or any other symbols.

The game’s history as neuroscience began in 1974 when Leonard Breen developed a color-grid permutation puzzle which later became a commercially available game named **Number Place(published in the journal of Dell Magazines)**. The game was introduced to the US and later renamed to Su Doku or Sudoku. Some have mis-attributed its Japanese influences to the Swiss mathematician **Leonhard Euler’s Latin Squares Theory**.

Enhancing Soduku’s purported brain-boosting benefits is wide web-access and numerous applications which allow you to enjoy playing Sudoku while sitting in your gym equipment or free time at work break. The medium difficulty level or **diabolical** sudokus, in particular, can be very helpful mentally.

## Why Do People Get Stuck in Sudoku?

People get stuck in **sudoku** when they are unable to start or find the numbers crucial for forward progress to build from the hints given at the beginning or provided in later stages of the game. Whether it is having too many potential moves or no potential moves, not having a good strategy or techniques going forward, or some of the mistakes listed below, people stick on a sudoku puzzle because they cannot find the next step forward confidently.

There are several reasons why people can become stuck in **sudoku puzzles**. These primarily boil down to what makes a sudoku puzzle challenging, which involves various parameters such as the choice of numbers placed by the puzzle maker, the spatial pattern on the sudoku board, and the level of difficulty of the puzzle. The reasons listed below indicate why people are stuck in sudoku because these factors lead to harder puzzles, **clues that communicat**e nothing to the player, and other common blockers. More reading related to points of becoming stuck include the links to pages such as Difficult Words in Sudoku and Strange but Real-Life Mistakes in Sudoku found in the Points of Getting Unstuck section.

### What Are the Common Mistakes Made in Sudoku?

The common mistakes made in Sudoku include inputting **incorrect numbers**, inputting **too many numbers** before evaluating the board, inputting **too few numbers** in a manner that leads to the puzzle being **unsolvable** due to lack of information, and not using the **process of deduction**. These mistakes may have various reasons but are linked to the most detrimental one which is **not carefully evaluating one’s moves**.

### What Are the Different Strategies for Solving Sudoku?

The different strategies for solving Sudoku are divided into **basic strategies** and **advanced strategies**. **Basic strategies** are faster and more efficient and include solving it via **filling in all empty cells**, **Guessing and Checking**, using a **Sudoku Pencil Marking System**, and spotting frequently occurring patterns for pre-processing. **Advanced strategies** are slower but with higher satisfaction and include making use of **remote pairs**, **forcing chains**, **jellyfish**, or other complex **pattern matching or advanced algorithms** you can learn to guess and double-check the limited available solving options.

## How to Get Unstuck in Sudoku?

You can get unstuck in Sudoku by trying different filling patterns for elements within rows, columns, and boxes. Each time you add a number to one cell you are eliminating other possibilities from other cells. When you are stuck in Sudoku and unsure which numbers to try, try to logically figure out where it is easy to add the least number of numbers and where you are likely to be left with the most possible targets later on, after you have added the new number.

You are stuck because you have accumulated many solved cells dependent on a single unsolved cell. If you only ever have one possible candidate, then you will be stuck. So try to minimize the number of solved cells which depend on a single unsolved cell.

### Take a Break

One of the simplest solutions is to just take a break. Pressure builds when you think you are stuck, and often solutions can not present themselves under stress. It is often the case that after stepping away from the **sudoku grid**, the answer becomes immediately obvious as soon as you sit back down to solve the puzzle.

Staring at the puzzle for hours on end typically makes you irritated and less able to make logical decisions, while taking a break can help refresh your mind. Going out for a walk to get some fresh air or working on a different task for a few minutes can reset your brain and help you see the grid in a different light when you come back to it, but you are advised not to take a break that lasts about 10 minutes for the best results.

### Start with the Easiest Numbers

When **playing Sudoku puzzles**, you must first **fill the squares with the smallest digits** known. As you fill in the easier digits, other numbers will emerge. Fill out the next easiest set of digits and repeat the process until the entire **Sudoku puzzle** is filled out. This is the most mentally challenging step, as it involves simply being patient and methodical while focusing on solving the puzzle.

A **harvard.edu article** on selecting and preparing new hires states that mastering fundamentals often leads to better overall performance. Focusing on internal training as a means of increasing **performance levels** on a team is often a wise move to contribute to employee success at foundational levels. Merely memorizing the basics of a Sudoku puzzle can indeed help one progress and notice patterns better in the future.

### Use Pencil Marks

**Unstick your stuck Sudoku** by using pencil marks to act as placeholders until only one option is left. One of the biggest causes of getting stuck is not seeing all of the possibilities for a square. The best recommendation is to have a tracking method such as shading squares in your notebook, or a digital pencil note available that you can use to place options until deciding on one. This is called doing the markups.

### Look for Patterns

When you have an incomplete sudoku and are stuck on how to move forward, one approach is to look for patterns that tell you what might be missing on a Sudoku grid. Which finishing numbers will make the puzzle finally be solvable? Some typical patterns with which to get unstuck at this challenging final phase are **Disjoint Subcycles, Bivalue Cells, Digit Forcing Chains** and subsequent solved numbers.

### Try Different Approaches

If you feel stuck in a Sudoku puzzle, you should try different approaches. Different puzzles may lend themselves to different strategies. A strategy that has worked for you in the past may just not work for your current puzzle. Switch up methods and try different ways of working the puzzle to get a fresh perspective. According to problem-solving expert **Ron Jonash**, chances are you will find the correct path sooner rather than later.

### Use Online Solvers or Apps

**Online sudoku solvers and apps** like the one offered by **kuSolver** are tools that may help you become “unstuck” by solving even the most difficult original puzzles. Solvers and apps can show you the next step when you are truly stuck and unable to proceed via normal logical progression to regain forward momentum.

If you find yourself at one move or **single-digit guessing game** when you prefer a quicker advancement, use the solver on **kuSolver.com** to shortcut the solution for you. Just enter the numbers of the initial grid where known, and click Solve Init. The solver will open a modal window with step-by-step instructions on how to solve your particular variant of the grid. The app can even tell you the necessary pencil marks for the the six methods of advanced sudoku solving described in Step 3 above.

Solvers are helpful if you are stuck in any stage of the puzzle from the very beginning to the advanced portion. On the other hand, before turning to the solver, try revisiting prior steps using the above methods to determine ways forward that may not have been considered.
