In the startup and tech world, you often hear about overnight successes, but the story of CardGames is a notable exception. IO is different. It’s the story of a hobby that inadvertently turned into a full-fledged business—the path from a programmer coding in. The NET card game website wasn’t exactly planned; it evolved more or less. The site is a result of an evident passion for card games, programming, and doing something meaningful, but straightforward—the founder of CardGames. Io transformed a leisurely pastime into a lucrative enterprise, demonstrating that ideas don’t always have to be huge to become a hit.

How Cardgames.Io Came To Life

Back in the day, the founder was a teenager graduating from a computer science school, working as a programmer. His regular job was humdrum corporate programming. NET, but he had not been entirely happy with it. Programming was engaging, but the projects were predominantly about infrastructure and backend work, not something he could obsess over creatively. So, he began working on side projects — small, fun programming tasks that he enjoyed doing outside of work.

Their first significant side project was a card game they named Shithead (or Idiot in other parts of the world). Disappointed with the poor quality of what is available online of this game, the founder created his own. With basic HTML and JavaScript, he crafted a stripped-down version of the game that players could load directly in their web browser. This was the beginning of CardGames.io.

The First Game: Card Games Are Born

Knowing virtually nothing about game engines, the founder was able to cobble together something straightforward, but it worked. It was incredibly simplistic, with no animations, terrible graphics, and a fundamental interface. Yet, it worked. It was a hit, in part because there were no other online versions of the game. It wasn’t the prettiest thing, but it worked, and many players loved the game.

Main features of the first game:

  1. Loads in the browser, so you don’t have to download.
  2. Simple but engaging game mechanics.
  3. A couple of simple card games with simple rules.

The popularity of this simple card game led to the development of others. Soon, the founder expanded the site by adding games such as Hearts, a classic card game. The tiny, quirky side project quickly drew attention and traffic.

Monetising: Making Money From Something You Enjoy Doing

However, while the games were a labour of love, the creator quickly realised he could monetise the site. He installed Google AdSense on the site and began generating a small revenue. It took months to make the first $100, but once traffic started to rise, the income followed. The site became profitable enough by 2012 that it eclipsed the salary the founder made at his day job as a programmer.

When the site became successful in 2014, the founder quit his job and began working on CardGames full-time. I’m full-time. This was the turning point. From a hobby, CardGames.Io passed from an experiment into a real business opportunity.

Working Full-Time On CardGames.Io

As CardGames.Io took flight, and the founder grew his team and operations. In 2017, he employed two students part-time. The team expanded, and in 2018, the founder hired two full-time developers to work on the site. The expanding team allowed the business to scale and to add more games to the site.

But the shift from hobbyist to professional changed the nature of the job. Its founder had come to understand that when you turn your hobby into your career, it’s no longer pure fun. Coding, which was an exciting hobby, became a job. This change caused the founder to pause coding for himself. He stopped coding at home, instead embracing hobbies like playing the piano and watching Netflix.

The Magic: It’s Easy To Use And Simple

The primary reason for CardGames.IO is its simplicity. There are numerous 3D online card games available on the market today, but CardGames.Io kept things simple. The website’s design is also barebones, featuring only one button to begin the game. There are ads on the side, but it’s not a game killer. And for some players who value simplicity for simplicity’s sake, that simplicity is precisely what they wanted.

Also, many of the games featured have simple AI, so one can easily play even by oneself;) It was the right mix of easy to use, easy to get into, and no bells and whistles that made the site very attractive, particularly to older members.

Technology Choices: Simple And Lightweight

One of the most important reasons is that on CardGames. IO has permeated its founder’s insistence on simplicity in technology. “Our website wasn’t even dynamic on the back end back in the day. It didn’t do anything other than serve static HTML files from Amazon S3. There were no convoluted systems in place — just games anyone could play in their browser at no cost.

But over the years, the site grew to include high score tracking for games of Solitaire and, during the pandemic, the ability to play with multiple other people. But there, too, the founder continued to stick to his principle of simplicity. He didn’t use third-party analytics or gather personal data, which helped make the site secure and low-maintenance.

The Future Of Cardgames.Io

The future of CardGames. The creator’s identity is unknown, but their goal is simple — to keep it simple and provide fun, easy-to-play games. There are over 40 games on the site already, so the number of games the platform is likely to add is probably not going to be that large. Instead, the focus is shifting toward enhancing the user experience and developing apps that are unrelated to the website.

Key Future Plans:

  • Open up the current library of games.
  • Focus on improving user experience.
  • Publish new apps that are (un)related to the site.

Even with its success, the founder has come to terms with the peculiar reality of his business. He’s going to be explaining to people for the rest of his life how you can make a living from creating card games for old people online!”

In conclusion

At first, CardGames.io was only a hobby, but it grew into a profitable gaming site. Many players, especially older ones, liked it since it was easy to use, had a basic design, and included engaging games. What started as a simple test grew into a popular online card gaming site.
