## Sudoku for Beginners: How to Improve Your Problem-Solving Skills

Are you a beginner when it comes to solving Sudoku puzzles? Do you find yourself frustrated and unsure of where to start? Fear not, as we have compiled a comprehensive guide on how to improve your problem-solving skills through Sudoku.

## Understanding the Basics of Sudoku

Before we dive into the strategies and techniques, let’s first understand the basics of Sudoku. A Sudoku puzzle is a 9×9 grid that is divided into nine smaller 3×3 grids. The objective is to fill in each row, column, and smaller grid with numbers 1-9 without repeating any numbers.

## Starting Strategies for Beginners

As a beginner, it can be overwhelming to look at an empty Sudoku grid. But don’t worry. There are simple starting strategies that can help you get started. First, look for any rows or columns that only have one missing number. Fill in that number and move on to the next row or column with only one missing number. Another strategy is looking for any smaller grids with only one missing number and filling in that number.

## Advanced Strategies for Beginner/Intermediate Level

Once you’ve mastered the starting strategies, it’s time to move on to more advanced techniques. One technique is called “pencil marking.” This involves writing down all possible numbers in each empty square before making any moves. Then use logic and elimination techniques to cross off impossible numbers until you are left with the correct answer.

Another advanced technique is “hidden pairs.” Look for two squares within a row or column that only have two possible numbers left. If those two possible numbers exist in both squares, then those two squares must contain those specific numbers.

## Benefits of Solving Sudoku Puzzles

Not only is solving Sudoku puzzles fun and challenging, but it also has many benefits for your brain health. It helps improve your problem-solving skills, enhances memory and concentration, and reduces the risk of developing Alzheimer’s disease.

In conclusion, Sudoku is a great way to improve your problem-solving skills while also providing entertainment. With these starting and advanced strategies, you’ll be able to solve even the toughest Sudoku puzzles. So grab a pencil and paper and start sharpening those brain muscles.

## The 10 Most Popular Coding Challenge Websites [Updated for 2021]

A great way to improve your skills when learning to code is by solving coding challenges. Solving different types of challenges and puzzles can help you become a better problem solver, learn the intricacies of a programming language, prepare for job interviews, learn new algorithms, and more.

Below is a list of some popular coding challenge websites with a short description of what each one offers.

## 1. TopCoder

TopCoder is one of the original platforms for competitive programming online. It provides a list of algorithmic challenges from the past that you can complete on your own directly online using their code editor. Their popular Single Round Matches are offered a few times per month at a specific time where you compete against others to solve challenges the fastest with the best score.

The top ranked users on TopCoder are very good competitive programmers and regularly compete in programming competitions. The top ranked user maintains his own blog titled Algorithms weekly by Petr Mitrichev where he writes about coding competitions, algorithms, math, and more.

## 2. Coderbyte

Coderbyte provides 200+ coding challenges you can solve directly online in one of 10 programming languages (check out this example ). The challenges range from easy (finding the largest word in a string) to hard (print the maximum cardinality matching of a graph).

They also provide a collection of algorithm tutorials , introductory videos, and interview preparation courses . Unlike HackerRank and other similar websites, you are able to view the solutions other users provide for any challenge aside from the official solutions posted by Coderbyte.

## 3. Project Euler

Project Euler provides a large collection of challenges in the domain of computer science and mathematics. The challenges typically involve writing a small program to figure out the solution to a clever mathematical formula or equation, such as finding the sum of digits of all numbers preceding each number in a series.

You cannot directly code on the website in an editor, so you would need to write a solution on your own computer and then provide the solution on their website.

## 4. HackerRank

HackerRank provides challenges for several different domains such as Algorithms, Mathematics, SQL, Functional Programming, AI, and more. You can solve all the challenge directly online (check out this example ).

They provide a discussion and leaderboard for every challenge, and most challenges come with an editorial that explains more about the challenge and how to approach it to come up with a solution.

Currently, if you don't solve the problem, then you can't see the solution of others. If you also try to check the editorial before solving the problem, then you won't get the point for solving the problem at all.

As an example, here I haven't solved the problem, and I am trying to check others' submissions:

And here, I haven't solved the problem, and I am trying to check the editorial:

HackerRank also provides the ability for users to submit applications and apply to jobs by solving company-sponsored coding challenges.

## 5. CodeChef

CodeChef is an Indian-based competitive programming website that provides hundreds of challenges. You are able to write code in their online editor and view a collections of challenges that are separated into different categories depending on your skill level (check out this example ). They have a large community of coders that contribute to the forums, write tutorials , and take part in CodeChef’s coding competitions .

## 6. Exercism.io

Exercism is a coding challenge website that offers 3100+ challenges spanning 52 different programming languages. After picking a language that you'd like to master, you tackle the coding challenges right on your machine (Exercism has their own command line interface that you can download from GitHub).

It is a bit different from other challenge websites, however, because you work with a mentor after completing each challenge. The mentor reviews your answers online and helps you improve them if needed. Once your answers have been approved and submitted, you unlock more challenges.

## 7. Codewars

Codewars provides a large collection of coding challenges submitted and edited by their own community. You can solve the challenges directly online in their editor in one of several languages. You can view a discussion for each challenges as well as user solutions.

## 8. LeetCode

LeetCode is a popular Online Judge that provides a list of 190+ challenges that can help you prepare for technical job interviews. You can solve the challenges directly online in one of 9 programming languages. You are not able to view other users' solutions, but you are provided statistics for your own solutions such as how fast your code ran when compared to other users' code.

They also have a Mock Interview section that is specifically for job interview preparation, they host their own coding contests , and they have a section for articles to help you better understand certain problems.

Sphere Online Judge (SPOJ) is an online judge that provides over 20k coding challenges. You are able to submit your code in an online editor . SPOJ also hosts their own contests and has an area for users to discuss coding challenges. They do not currently provide any official solutions or editorials like some other websites do, though.

## 10. CodinGame

CodinGame is a bit different from the other websites, because instead of simply solving coding challenges in an editor, you actually take part in writing the code for games that you play directly online. You can see a list of games currently offered here and an example of one here . The game comes with a problem description, test cases, and an editor where you can write your code in one of 20+ programming languages.

Although this website is different than typical competitive programming websites such as the ones mentioned above, it is still popular amongst programmers who enjoy solving challenges and taking part in contests.

This list was based on a few things: my own experiences using the websites, some Google searches , Quora posts , and articles such as this one and this one . I also frequented some forums and subreddits such as r/learnprogramming to see what websites were usually recommended by the users there. Disclaimer: I work at Coderbyte which is one of the websites mentioned above.

## 5 Best Coding Challenge Websites In 2023

Looking to find the best coding challenge websites to improve your coding skills and land that next job? Well, look no further, because today we are going to break down the top coding platforms to improve your coding skills!

While all of these challenge sites aim to improve your algorithm & data structure skills, only a few are successful. Additionally, every coding challenge site seems to focus on different aspects that make each platform unique and useful in its own way.

As a developer trying to teach yourself how to code, it’s important to be using the right tools to make the learning process easier and faster. By understanding the benefits and drawbacks of each platform, you can be sure you are being as efficient with your time as possible.

So without further ado, let’s jump right in and discover some of the best coding challenge sites to improve your skills.

## Best Coding Platforms

1. hackerrank.

Let’s start things off with one of my favorite challenge sites, HackerRank . HackerRank’s mission is to help prepare software developers for technical interviews and improve their coding skills with a series of coding challenges in major divisions of coding.

The platform has a well-defined area to teach algorithms and data structures that any self-learner would be satisfied with. What really makes HackerRank stand out, however, is that you can also learn specific programming languages and mathematic concepts as well.

You can check out all of the available subjects below:

HackerRank does a great job of connecting developers and employers through their job board, has exceptionally well-organized coding challenges, trusted high-quality free content, a realistic coding environment, and best of all, is fun to use!

## 2. Codewars

Codewars is another one of the best coding challenge websites in 2023. The site features a ton of great challenges that will push your abilities and increase your skills as a programmer. It also features one of the largest language supports of any site on this list. Codewars supports 29 core languages and 26 additional beta languages!

A big difference between Codewars and HackerRank is that Codewars seems to focus more on building a community than HackerRank . Users are motivated to create their own challenges, monitor the site, and join clans. The site basically maintains itself because of the members that use it.

If you are looking for a coding challenge website that focuses more on social aspects, Codewars is probably the coding site for you.

You can check out our full review of Codewars here .

## 3. LeetCode

LeetCode is the golden standard for technical interviews and our favorite coding challenge site for landing your next job. We found that LeetCode’s thousands of free challenges were the best laid out of all the sites on this list. It features a tagging system that makes it easy to practice algorithmic challenges related to each other and the description of the challenges is also very easy to understand.

In addition, they have lists of the most popular tech interview questions on their site. Including questions asked at top tech companies like Google, Facebook, Amazon, and Microsoft.

Comparing LeetCode to Codewars , it’s obvious that LeetCode lacks the social aspect you may find in Codewars. However, if you want a no-nonsense coding challenge site to improve your skills, look no further than LeetCode!

## 4. CodeChef

If competitive programming is your style, CodeChef is the coding platform for you! Among the typical algorithmic challenges you’ll find on all of these sites, CodeChef also offers many coding competitions. You can find the most recent challenges to show off your skills here .

Competitive coding aside, there isn’t much at CodeChef that you can’t find a better version of in the coding sites above. While CodeChef will certainly improve your coding skills, if you aren’t looking for competitive coding, you may be wasting your time with CodeChef.

CheckIO gives an interesting approach to coding challenge platforms. Instead of setting out a list of coding challenges laid out by a tag system, CheckIO treats learning how to code like a game!

CheckIO’s main purpose is to be used as supplementary material for teaching a class. For that reason, it isn’t a great option if you are preparing for an interview. However, if you want a fun, interactive way to learn how to code, CheckIO may be the right coding platform for you.

If you are a teacher it also offers an admin section that allows you to track and understand the progress of your students. A feature that is not available in any other coding platform in this list!

It’s a cool approach and we recommend you check out the full CheckIO review here .

## Wrapping Up

As you can see, there are a ton of great options available to you in the realm of code challenge sites. Some of these are better geared towards nailing your coding interviews, while others are focused more on social community, learning languages, or competitive programming. Which coding site will you choose to improve your coding skills?
