Average Solving Time

Knowing what the average solving time for a Sudoku puzzle is can provide a helpful benchmark for you to speed up your own times.

General Averages

Generally speaking, the average time taken to solve any Sudoku puzzle is usually between 10 and 30 minutes. Of course, some Sudoku experts who have spent years perfecting the art of fast puzzle solving will be able to solve even the hardest puzzle in less than 10 minutes. However, on average, 10 minutes is the time you can expect it to take to solve an easy to medium level Sudoku puzzle. A hard or expert level Sudoku puzzle takes an average of 30 minutes.

Understanding the Range

These averages provide a general guideline, but actual times vary significantly based on individual skill, puzzle characteristics, and solving approach. Don't be discouraged if your times differ from these averages—focus on your own progress and improvement rather than comparing to others.

Factors Affecting Time

The average Sudoku completion times give a rough estimate of how long you may expect it to take to complete a puzzle. However, it's essential to keep in mind that the actual average solving times will depend on a few different factors. These factors include:

Your Sudoku Expertise and Experience

The number of Sudoku puzzles you've completed in the past, and your level of expertise will have a significant impact on how quickly you can complete a Sudoku. Some people find they have a natural aptitude for these types of logic puzzle and can solve them pretty quickly from the get-go. However, for most people, it takes a little while to get familiar with the way that Sudoku works and how to solve the puzzles quickly.

With this in mind, it's important to remember that if you're new to Sudoku, it can be unhelpful to put pressure on yourself to solve puzzles in the fastest time possible. Instead, it's much more useful to give yourself the time you need to complete a puzzle so that you can figure out the best Sudoku solving methods that work for you and increase your familiarity with the grid.

The Sudoku Puzzle's Difficulty Level

Sudoku puzzles can vary hugely in terms of difficulty. Simpler puzzles will already have many of the numbers already in place on the grid. The more numbers that are already filled in for you, the lower the difficulty level of the Sudoku.

As a more difficult puzzle has fewer numbers already in place, you will need to spend far more time examining the grid and implementing your Sudoku strategies to try and solve it. With so many potential answers, it can take significantly longer to figure out number positioning and solve the Sudoku.

The Size of the Sudoku Puzzle

The size of the Sudoku puzzle that you are working on will also influence how long it takes to solve. While they may vary in difficulty, 3×3 Sudoku grids are generally easier and faster to solve than larger grids, such as the 4×4. This is simply because there are far more variables at play, and an increased amount of numbers to include in the grid.

Beginner vs. Advanced Times

As you can imagine, there is a vast difference between the time taken by a complete beginner to solve a Sudoku puzzle compared with an advanced, experienced Sudoku expert.

Beginner Completion Times

On average, a beginner takes between 15 and 20 minutes to solve an easy puzzle. Beginners need time to understand the rules, recognize patterns, and apply basic solving techniques. This learning phase is essential for building a solid foundation.

Advanced Solver Times

In contrast, an advanced Sudoku enthusiast can solve the puzzle in under 5 minutes. Advanced solvers have internalized techniques, developed pattern recognition, and can apply multiple strategies simultaneously, dramatically reducing solving time.

World Record Times

In 2006, Thomas Snyder of the USA broke the Guinness World Record for the fastest time to complete an easy Sudoku, which he solved in just 2 minutes 8.53 seconds. This record was broken in 2018 when Sudoku master Wang Shiyau completed a 9×9 Sudoku in just 54.44 seconds. These exceptional times demonstrate the potential for speed with extensive practice and technique mastery.

Techniques for Faster Solving

As you can see, there is a vast difference between the time taken to complete an easy puzzle and a difficult one, and how long the same Sudokus can take to complete by a beginner versus an advanced Sudoku master. If you're concerned that your Sudoku skills are more at a beginner level, there's no need to worry. The only thing standing between you and a fast Sudoku completion time is technique.

Developing your Sudoku technique is well worth the effort. There are some surprisingly simple strategies available that can significantly speed up your gameplay. Here are some helpful techniques to try to encourage faster solving:

Choose an Area to Focus On

Focus your attention on one area of the grid and attempt to solve it. By concentrating on a specific section, you can make progress more efficiently than trying to work on the entire grid simultaneously. This focused approach helps you build momentum and create a foundation for solving the rest of the puzzle.

Look for Quick Wins

Some parts of the grid may be easy to solve right away. Get these completed first, and the rest of the grid should be easier. Identifying and solving easy placements early provides information that helps with more difficult sections later. Quick wins build confidence and create a sense of progress.

Do a Fast Scan

Scanning each line and grid in a logical order will enable you to quickly see where numbers are missing and can be filled in right away. Scan the surrounding numbers for some easy solutions that will get the grid filled up faster. Systematic scanning prevents you from missing obvious placements and helps you identify patterns more efficiently.

Tracking Your Progress

Now that you're familiar with some of the main techniques you can try to speed up your Sudoku completion rate, it's time to start tracking your progress. If you plan to track your progress in the hope that you will see your completion times get faster and faster, you need to decide how you will do this in a precise way. You may wish to try the options below:

Use a Stop Watch

Start a stop watch each time you work on a Sudoku and ensure that you record the time and date that you completed it. You can then keep an accurate record of your progress. This method works well for paper puzzles or when you want detailed tracking of your solving sessions.

Set Your Timer

Set a timer to the last recorded time that you completed a Sudoku, and then challenge yourself to complete it before the timer runs out. This is an exciting way to challenge yourself. Timer challenges create motivation and help you push your limits while maintaining focus.

Play Online

Playing Sudoku online gives you a couple of really helpful ways to track your progress. Firstly, you will notice that when you start a new game, a timer appears in the game, and precisely measures how long it takes you to complete the game.

If you are feeling particularly competitive, you may choose to use another feature, which is the leaderboard. Checking out your ranking on the leaderboard every time you play enables you to compare your performance against thousands of other players who are also attempting to solve the Sudoku in the fastest time.

Tracking your progress is an excellent way to add some extra fun to your Sudoku gameplay and to chart your improvements over time.

Don't forget to stick with the same difficulty level while tracking your progress. This will help you to get more accurate results and a true measure of how your times are improving.

Dealing with Difficult Puzzles

Every now and then, a difficult Sudoku puzzle will come along that leaves you scratching your head and wondering how on earth it can be solved. Puzzles like these can seem impossible at the time, and you may even feel like giving up on them.

After working so hard to improve your puzzle solving times, you certainly don't want to give up on all the progress you have made so far. Here are some tips to try out when you're faced with a Sudoku puzzle that feels impossible to complete:

Stay Calm

Attempting to solve a Sudoku that feels impossible while watching the clock quickly count away the minutes and seconds can make you feel super stressed. Being in panic mode can make it even harder to stay focused and think logically. In this situation, it's helpful to take a deep breath, and to re-focus on what you are trying to achieve. You may even find it helpful to look away from the puzzle for a few moments so that you can return to it with fresh eyes.

Engage Your Techniques

Attempting a difficult puzzle is the perfect time to revisit your Sudoku solving techniques. A back to basics approach to your gameplay can help you to follow a strategy that you know has worked for you in the past. Applying this to a difficult puzzle can give you the confidence needed to solve the Sudoku more quickly.

Focus on One Area

If a difficult puzzle is making you feel overwhelmed, you may want to focus your attention in a different way. Instead of attempting to solve the entire grid, instead, choose a line or a 3×3 box to focus on. Directing your attention to this smaller area can make it easier for you to see solutions. In turn, solving these smaller areas can provide the perfect foundation for solving the rest of the grid.

Tips for Time Management

Managing your time effectively when working on a Sudoku puzzle is crucial when you want to challenge yourself. It's so easy to get overwhelmed by a tricky Sudoku and end up wasting precious minutes of your time.

To avoid wasting time, it's helpful to have some time management tactics already in place that you can implement when you need them. Here are some ideas to help you get started:

Set Yourself a 5-Minute Limit

Spending too long attempting to solve one part of the grid that you are stuck on can see your progress halt and your time increase. Give yourself five minutes, and if you've still not made any progress, you can then move onto another area. This prevents you from getting stuck and wasting time on unproductive sections.

Don't Hesitate

When you're up against the clock, you can become so concerned about getting it right first time and not making a mistake that you don't end up committing any numbers to the grid. When you're trying to work quickly, it's important that you don't hesitate, and simply keep working, rather than leaving the grid blank. Confidence in your logic helps you make progress faster.

Improving Your Speed

Improving your speed is all about finding the right strategy. These ideas should help you to devise a strategy that works for you:

Choose the Right Level

Forcing yourself to play at a high level before you're ready can have a really negative impact on your speed. Instead, try sticking with the same level and ensure your times improve before moving on. Building speed at your current level creates a solid foundation for advancing to harder puzzles.

Find Your Perfect Technique

There are many possible techniques that can be used to improve your speed. So, trying them out and establishing which one gives you the best results is essential. Once you've found your winning formula, your times should improve significantly. Different techniques work better for different people, so experimentation is key.

Practice Each Day

It's essential to remember that improving your Sudoku solving speed isn't something that happens overnight. Spending even five minutes each day solving Sudokus can really help you to build up your speed. Consistent practice builds pattern recognition, technique mastery, and solving confidence.

Playing Sudoku online will help you to increase your speed quickly thanks to its multiple levels of play and daily challenges. As you play, you will be able to see your progress for yourself as you speed up and rise through the rankings.

How Online Play Affects Solving Time

Summary

Understanding how long Sudoku takes to complete helps you set realistic expectations and track your progress effectively. Average solving times range from 10-30 minutes, with easy-medium puzzles taking about 10 minutes and hard-expert puzzles taking about 30 minutes. However, actual times vary significantly based on your expertise level, puzzle difficulty, and puzzle size.

Beginners typically take 15-20 minutes for easy puzzles, while advanced solvers can complete them in under 5 minutes. World records show that exceptional times under 1 minute are possible with extensive practice and technique mastery.

The key to improving your solving time is developing your techniques, tracking your progress, managing your time effectively, and practicing regularly. Techniques like focusing on one area, looking for quick wins, and doing fast scans can significantly speed up your solving. Time management strategies like setting 5-minute limits and avoiding hesitation help prevent wasted time.

Remember that improving speed takes time and practice.
