Are you interested in creating a gaming website on WordPress? Gaming has never been more popular than it is now. With our own gaming website, we can build a gaming community, run a popular gaming blog, and even earn extra income.

What do we need to create a gaming website using WordPress?

Initially, we will need the following to create a gaming website on WordPress.

  • Domain name . This will be the name of our website that people will type to find our site online. For example, com.
  • Web Hosting Account. Our website files will be stored in this account.
  • WordPress theme. The theme will be responsible for the appearance and functioning of our site.
  • Correct and suitable WordPress plugins. Plugins will help us add certain gaming features that we need.
  • SSL certificate. We will need an SSL (Secure Sockets Layer) certificate if we plan to sell products or add Twitch streams.

Depending on the type of gaming website we’re building, it’s entirely possible to do this in less than an hour. Let’s see how to carry out this process, step by step.

1. What type of WordPress gaming site do we need?

If we like video games, there is nothing better than participating in this segment.

Gaming blogs and websites serve a large community of gamers who are looking for articles about the latest games, consoles, hardware, events, and more.

Let’s see what kind of gaming sites we can create using WordPress:

  • A site that sells products to the gaming community.
  • A site that hosts simple and fun online games and lotteries (see our sample Fastloto).
  • Website with game reviews and news blog.
  • A gaming forum dedicated to our favorite game.

If we make the right choices, perhaps we will compete with IGN, Kotaku or GamesRadar.

No matter what type of gaming website we want to create, this guide will help us create it using WordPress.

2. Choose the right platform for your website

To begin with, we must choose a website builder that best suits our idea.

We will definitely choose WordPress. However, there are two types of WordPress software that have the same name, so it’s easy to confuse them.

First, we have WordPress.com, a blog hosting platform. The second is WordPress.org, a standalone version of WordPress.

We recommend using the local version of WordPress.org as it gives us more freedom, control and access to all WordPress features.

Next we will need a domain name and web hosting. But we don’t need just any hosting company. We need a high quality hosting provider like SERED to support our WordPress website as it grows.

After purchasing hosting, the content management system (CMS) WordPress will be automatically installed.

If we prefer, we can install WordPress ourselves. For more details, we recommend reading our complete guide to installing WordPress.

Once we’ve installed WordPress, it’s time to set up the rest of our WordPress gaming website.

3. Choose the perfect responsive gaming WordPress theme.

After setting up our WordPress site, the next step is to choose the perfect WordPress gaming theme.

When we search for the best gaming WordPress theme, we find several options with built-in gaming features.

While this may seem like a good idea, we should actually avoid using these themes.

We don’t want a WordPress theme built for games.

Most WordPress gaming themes are bloated and will make us use them forever. We may even encounter compatibility issues when trying to add new features to our site.

It’s better to choose a high-quality, flexible theme and add more functionality using WordPress plugins. There are a large number of different plugins that will help us select the functions we need.

By adopting this approach, we have the ability to change themes in the future while maintaining the same functionality without having to hire a WordPress developer.

The magazine template can be ideal for gaming websites because it models what other large and successful sites in the gaming space are doing.

4. Install the correct game plugins

It’s time to add more functionality to our site using WordPress gaming plugins.

Plugins are supporting applications for our WordPress site. They allow us to add all sorts of features to our site. There are approximately 60,000 free plugins for WordPress.

Let’s see what gaming features we can add to WordPress:

  • Sale of goods related to the game or for instance, lottery tickets.
  • Live games that visitors can play.
  • Streaming video on Twitch.
  • Detailed video game reviews.
  • Gaming community forum.
  • Selling Game Related Products on WordPress

Perhaps our goal in creating a gaming site is to sell our own gaming manuals and equipment.

These can be special gaming glasses-accessories that are designed to reduce eye strain.

Or masters who are specialists in a particular game, and we want to sell courses and walkthroughs. WordPress makes it easy to create your own online store selling digital or physical products.

To start selling products using WordPress, you need to use the WooCommerce plugin.

Add Attractive and Simple Games to WordPress

We might be wondering how to add games to a WordPress site.

Adding games to our site can provide entertainment for our visitors and hopefully leave them with a positive experience. The best way to add games to our site is with a WordPress gaming plugin.

There are plugins such as Dinosaur Game and Word Search Puzzle Game that allow us to add simple games to our site.

If we want to turn our WordPress website into an online gaming platform, we recommend using MyArcadePlugin. This is a premium plugin used by over 100,000 WordPress sites.

Add Streaming Feature to WordPress

If we broadcast or want to include popular Twitch and Esports video streams on our gaming site, we can easily do so.

The best way to add this feature is to use a WordPress plugin. We recommend using the Twitch TV Easy Embed plugin. This plugin allows us to embed Twitch.tv streams into WordPress and customize the appearance.

After installing and activating the plugin, go to “Settings” -> “Easy insertion for Twitch TV (Rail)”. On this screen we will find the main settings in which we can configure the shows we want to display.

With the free version of the plugin we can enter the game or channel that we want to broadcast. Finally, we made sure to click Save Channel before the screen appears. This is what the screen will look like when you add a Hearthstone game to Twitch.

To add Twitch streams in WordPress, we can use the [getTwitchRail] shortcode.

We simply copy the shortcode and paste it into any post or page or even into our sidebar widget.

We just need to make sure to click the Publish or Update button to save our page and start our Twitch stream.

If we want to add an entire wall of Twitch streams to WordPress, we can use the Twitch TV Easy Embed (Wall) plugin. This plugin was created by the same team of web developers and follows the same setup instructions as the previous plugin.

Add game reviews to WordPress

If we’re gaming bloggers writing about games, hardware, and consoles, we’ll probably want to add advanced review features to our site.

This way, when we write product reviews, we can add star ratings and improve their appearance. Let’s see below how our reviews will stand out in search engines:

The best way to do this is to use the WP Product Review Lite plugin. This plugin allows us to manage reviews games and display them on our website.

Additionally, this plugin gives us customization options that allow us to add pros and cons, product images, ratings, and more to our reviews.

There is even a feature to add a sidebar, top products and review widgets to our site.

We may also be interested in using plugins like Pretty Links or ThirstyAffiliates to better monetize our website with affiliate marketing for beginners.

Create a gaming forum in WordPress.

Another great feature we might want to add to our site is our gaming community forum. A forum can be a discussion forum, a place to share tips on a specific game, or even a question and answer platform.

Forums allow our visitors to feel like they are part of our site. When they engage in discussion and share information with others, they are more likely to return to our WordPress blog and engage in other ways.

The best way to add forum functionality is to use a WordPress plugin such as bbPress or BuddyPress. These are two of the best WordPress forum plugins that will help us easily add forum functionality to our website.

5. Take our WordPress gaming site to the next level

WordPress is a very powerful and flexible platform that gives us access to thousands of different plugins that we can use to develop our gaming website.

The following plugins can help us grow our gaming website today.

  • WPForms Lite. This is one of the best contact plugins for WordPress that allows us to quickly create contact forms using a drag and drop builder.
  • AIOSEO. This is the best SEO plugin for WordPress that will help you rank higher in search engines.
  • MonsterInsights. This plugin allows us to easily install Google Analytics in WordPress so you can understand where our visitors are coming from and what content on our site is most valuable.
  • Break the balloon. This is the best social media plugin for WordPress that allows us to add our social media channels directly into WordPress.
  • SidProd Light. This is the best page builder plugin that allows us to easily customize our website using a drag and drop builder without the need for HTML.

We hope you found this article on how to create a gaming website with WordPress helpful.

My name is Maxim Chechenev, I have been a front-end developer for almost nine years. I work at MessageBird in Amsterdam and as a mentor in the “Web Developer” course at Yandex.Practice. I also run a telegram channel “Senior Developer”.

Before I became a senior and started interviewing candidates, I went through dozens of my own interviews. In this article, I will tell you what a Junior Front-End Developer interview usually consists of and give some tips for preparing.

What does an interview consist of?

The initial stages of a front-end developer interview are not much different from any other.

Typically the interview can be broken down into three parts:

  • acquaintance,
  • technical questions and/or assignment,
  • your questions.

Acquaintance

The best part. Here you talk about yourself, and the interviewers talk about the company, product, position and job responsibilities. At this stage there are no puzzles or correct answers – the conversation will be about your experience, education, hobbies.

Although there are no correct answers to this part, you still need to prepare for it. This stage is as important as the technical part. This is where your soft skills are tested, and sometimes you may be denied a job, even if you have shown yourself brilliantly on the technical side.

A story about yourself

Imagine you came for an interview at the company you dreamed of. The recruiter offered you a cup of coffee, asked how you got there, and then asked you to tell us a little about yourself. Such a simple question took you by surprise: “Where to start, should I tell about my education, hobby, or is only my experience important to the recruiter?”

There is no right answer or clear pattern here. But there are a few tips to pay attention to.

Prepare a short story about yourself.

Answer in such a way that it is not a long, complicated story, but also not: “My name is Maxim, I studied to be a programmer.” I advise you to practice the story on friends, family or a cat in advance.

Tell us what you learned.

If the training was non-core, explain how you got into development.

Invest time in development experience.

If you are a completely new developer, no worries. In this case, you can talk about educational projects.

Touch on the topic of your core hobby.

Describe a project you work on in your free time. Even if it seems to you that the project is simple, it is worth telling about it. This will show your interest in the development. A simple project that does not solve grandiose problems is much better than an empty Github profile.

After this, the recruiter may ask a few typical questions. I also advise you to prepare answers to them so as not to get confused.

“Why do you want to work with us?”

How not to answer: “Because you are a big company with many interesting tasks.”

Which answer do you like? Get to know the product and company better, find out what you like and what you don’t. Talk about this at the interview.

Be honest, but don’t be impudent. I recently interviewed a candidate from Brazil who, when asked: “Why do you want to work for us?” replied: “They pay more in Europe than in Brazil.” Even though this is the most honest answer possible, it shows that he doesn’t care where he works or what he does.

“Why are you interested in the frontend?”

I personally like to ask this question: “Why are you interested in the frontend? Why not the backend, for example?” — it perfectly shows the candidate’s interest and passion.

How not to answer: “Yes, I just tried it, it seems interesting.”

Which answer would you like: “I like creating user-friendly interfaces” or “I like design and programming, and front-end is just what I need.”

“Will we work together?”

Companies pay attention to different qualities of a candidate. Some care about your ability to work in a team, others care about your desire to learn, and others care about everything at once. But usually companies are looking for a person who will be on the same wavelength with the team. To understand this, I ask clarifying questions:

  • What are your hobbies?
  • What do you expect from working with us?
  • What would you like to improve in yourself?
  • What achievements are you proud of?

When answering the last question, you can talk not only about your achievements in programming, but also about the fact that you have learned a new language or are a master at skiing. In general, you probably have reasons to be proud.

Such questions help to get to know you better: what do you dream about and what are you interested in. They may seem a little personal to you, that’s okay. But by answering these questions honestly, you will feel the tension clearing up, and now you are ready for the next stage – the technical interview.

Technical interview

The technical part is different in each company. Unfortunately, there is no universal set of questions that everyone uses. But usually this stage consists of questions to understand basic terms, ideas about the frontend and small tasks. Someone may give a small task, and someone will ask for commsenter pieces of code.

First of all, carefully study the vacancy and the required technologies that are indicated in it. If React is specified, be prepared for questions about this library. If it says “We use Vue,” then React is no longer needed.

Theoretical issues

The block with theoretical questions can be divided into two: questions about knowledge of the basics of JS, CSS and other tools, and questions about how you are used to working with code.

Instrument Knowledge Questions

To prepare for the first block, it’s a good idea to brush up on some basic JavaScript theory, for example:

  • How does inheritance work?
  • What is closure and why is it needed?
  • How to search for elements in the DOM tree?
  • How does Event loop work?
  • What is this object?
  • What are data types and how do you compare them? What is the difference between == and ===? What are null and undefined?
  • How do the .filter, .map, .reduce methods work and why are they needed?
  • What is a Promise, why is async/await needed?

There are usually fewer questions about HTML and CSS. You may be asked: “Which selector is stronger – by ID or by class?” or “How do I center an element?”

Be prepared for clarifying questions, so don’t say anything you’re not sure about or something you only know superficially. Go through the theory of those points that seem least clear.

When I interview candidates, I like to ask questions about their understanding of technology:

  • Why do you need React? Why can’t we do without it?
  • I expect to hear what problems React solves, what Virtual DOM is, and how to save time and effort when writing an application.
  • Why are different methodologies and approaches needed when working with CSS?
  • It doesn’t matter to me whether the candidate likes BEM, CSS Modules or css-in-js. It is important to me that the developer understands what problems they are solving.
  • More than a thousand positions are displayed on the page, and the page begins to slow down. What’s the best way to fix this?

It would be great if the candidate talks, for example, about lazy loading or pagination.

I don’t expect detailed answers; it’s more important for me to understand the candidate’s interest and outlook.

Questions about work habits

In addition to questions about technology knowledge, you may be asked about how you work, for example:

  • When code doesn’t work, what’s the first thing you do and how do you solve the problem?
  • How do you name variables and functions?
  • How do you explore new technologies and approaches? What are you reading?

My favorite type of questions is when they tell you about a project or task that the team is already working on or will be working on. Then they ask how you would make it and where you would start. Here it is important not just to tell what technologies you would use, but also to actively ask clarifying questions: “What is already ready? What are the deadlines? Is there a design?

You will definitely be asked: “How long would this task take you?” It’s important to remember, there is no right answer here. They don’t expect an exact answer from you, but they do expect an adequate one. An answer like “I can do it in a couple of hours” will show that you may be overestimating yourself.

Assignment: What will this code do?

A very popular type of task in interviews. You are shown slides with different code and asked to say what the function will output, what the variable will be equal to, and so on.

Tasks

Companies like to give a small problem (the “Easy” level on LeetCode – like this one) to solve during the interview. Most often this is a small algorithm. For example, about working with strings or arrays.

The most important thing: do not rush to solve the problem, but first think a little. Ask the interviewer questions about the condition: what data may be here, what restrictions there are.

Think out loud. You are judged not only on whether you were able to solve a problem or not, but also on how you make decisions and perceive feedback.

How to prepare for such tasks?

Check out the “Easy” challenges on leetcode.com, hackerrank.com or codewars.com. Don’t try to solve them all at once in one evening. Do it a little at a time—one or two tasks a day.

It may immediately seem to you that such tasks make no sense and you will not encounter them in your work. I advise you to think of them as an exam, which, if you pass, will put you in good company. It’s like getting into university: to achieve it, you need to follow the rules and pass exams that you won’t remember in the future.

Your questions

Always, absolutely always, have questions ready. Remember that you don’t Not only are you being interviewed, but you are also interviewing the company. You work here and spend at least a third of the day – ask everything that interests you.

You will definitely be asked: “What questions do you have for us?”

How not to answer: “None.” You may want to finish the interview quickly and go home, but the hard part is over, you just need to show interest and find out everything that worries you.

Which answer would you like: “What will I work on if you hire me?” Listen to the answer and ask clarifying questions. Find out about the team, how the work process works, whether there is a code review, whether someone will train you. Ask about the company’s plans: what projects are they launching? What difficulties and challenges are there now?

Don’t be shy to ask questions; they only expect you to be sincerely interested in the work.

General Tips

  • Don’t be late. It sounds obvious, but it can affect all further communication. Even if it’s a remote interview, be on the call in a couple of minutes. If you are late, be sure to notify us.
  • Please read the job description carefully. Look at the company’s product if it already has one. This will help prepare for possible questions and tasks regarding company projects.
  • Don’t be silent, even if you don’t know the answer to a question. You can simply safely say: “I don’t know, but I guess like this…” Even if you are wrong, that’s okay. You need to show your interest and desire to understand.
  • Don’t answer in too long sentences. In the middle of them, it can be easy to lose the meaning of what you want to say.
  • Brush up on the theory.
  • Comment on your decisions.
  • Ask questions.
  • Get a good night’s sleep the night before. Rest is much more useful than theory learned overnight.

After the interview

You have been invited to work

If successful, everything is simple: you discuss salary, start date and celebrate.

You were refused

In case of refusal, you need to remain calm. Yes, it’s offensive, but accept the refusal proudly and calmly. You should not write in response: “You are a so-so company, and your questions are stupid, in general, I just stopped by on my way to the store.” IT is a very small world and you never know who you will encounter in the future. Instead, ask for detailed feedback on what you need to work on. After all, you can always try to get a job at this company again in six months or a year.

If a company gives you feedback, handle it carefully. Find answers to questions and solve problems that you were unable to solve during the interview. Only by learning from your mistakes can you become a good developer.

Don’t be afraid to go to interviews. This is an important experience that helps you recognize your weaknesses and improve them. Besides, the worst thing that can happen is rejection, but is that really that bad?

Diving into the Basics

Let’s start our adventure into the world of programming by understanding what it’s all about. Picture yourself as an explorer about to uncover hidden treasures.

What is Programming?

Imagine a symphony. An orchestra plays seamlessly together. Programming is like composing that symphony, but instead of musical notes, you’re using code to instruct a computer to perform tasks. It’s the art of creating, testing, and maintaining the source code of computer programs.

The Importance of Learning Programming

Why should you bother learning to program? Well, it’s like learning a magic spell that can solve almost any problem. From building apps to analyzing data, programming gives you the power to make things happen!

Setting the Foundation

Just as building a house requires a sturdy foundation, diving into the world of programming demands a solid base of understanding and skills. Let’s break down what goes into setting the foundation in programming.

Choosing Your First Programming Language

Picking a language is like picking a superpower. What do you want to achieve?

Python, The All-rounder

Python is like a Swiss Army knife. It’s simple yet versatile, making it perfect for beginners. Whether you’re into data science, web development, or automation, Python has got you covered!

Java, The Industry Veteran

If Python is the Swiss Army knife, then Java is the hammer. It’s strong, reliable, and heavily used in enterprise-level applications. If you want to build robust systems, Java should be your weapon of choice.

So, you’ve dipped your toes into the programming waters. But how do you go from paddling in the shallow end to swimming in the ocean of coding? It’s time to hone those skills, my friend!

Essential Tools for Programmers

Coding is just one part of programming. Like a chef needs more than just ingredients, you need the right tools. Learn about integrated development environments (IDEs), version control, and debugging.

Online Platforms and Resources

Wouldn’t it be cool if you had a mentor guiding you along? Well, you have a whole community! There are countless platforms like GitHub and Stack Overflow where programmers share and collaborate. It’s like a global playground!

Branching Out

In the world of programming, branching out refers to expanding your skills and interests beyond the basics. Picture yourself as a traveler standing at the crossroads of a giant, mystical land. Each path leads to a unique domain, rich with possibilities. The School of Programming is exactly that – a land filled with countless avenues to explore. Let’s dive into some exciting realms you can venture into.

Live Casinos and Programming

Believe it or not, programming extends to fun arenas like live casinos! They combine the thrill of real-life casinos with the convenience of online gaming. Programmers are the masterminds behind creating lifelike experiences. Pragmatic Play https://livecasinofinder.com/vendor/pragmatic-play/ is one such vendor creating top-notch live casino content. It’s like having Las Vegas at your fingertips!

The Internet of Things (IoT)

Picture this: your coffee machine starts brewing the moment your alarm goes off. With IoT, everyday devices are connected to make your life easier, and programmers are the wizards behind this magic.

Securing Your Future

Alright folks, imagine standing at the crossroads of your career, with a magic wand in your hand. Pretty cool, right? Well, that magic wand is programming, and the School of Programming is your Hogwarts. From conjuring up powerful software to summoning data at your fingertips, this is the place that can make your dreams come true.

Career Opportunities in Programming

Programming is like a golden ticket to Willy Wonka’s chocolate factory. The world is your oyster! From software developer to data analyst, the opportunities are endless.

Continuous Learning

Remember, learning never stops. The tech world is ever-evolving, and you’ve got to keep up. Think of it like updating your magical spellbook.

Conclusion

The School of Programming is not just a set of courses; it’s a lifelong journey. From mastering the basics to keeping pace with innovations, programming empowers you to be a creator in the digital world. So, are you ready to turn your dreams into code?
