I am a digital marketer, not a professional developer or game developer. Most of my career has been focused on SEO, growth marketing, paid acquisition, content, and digital strategy. When I started building GamesMom, however, I found myself learning much more about web development than I expected.
GamesMom is a collection of free educational games and learning activities for kids that run directly in the browser. The site includes math games, word games, typing games, memory games, puzzle games, classroom games, quizzes, and other interactive activities. The idea was simple: make games that children can open and play without downloading an application or creating an account.
I initially assumed that building browser games would require a dedicated game engine or a large JavaScript framework. After experimenting with different approaches, I found that many of the games I wanted to create could be built with ordinary HTML, CSS, and JavaScript.
That was probably the most useful lesson I learned from the project. You don't always need a complicated technology stack to create an interactive web experience.
I Started With the Simplest Approach
When you're not a professional developer, it is tempting to look for the most sophisticated solution available. I did this too.
I spent time looking at frameworks, game engines, libraries, and different ways of structuring interactive applications. Eventually I started asking a much simpler question: what does this particular game actually need?
A basic educational game might need to display a question, accept an answer, update a score, show feedback, and move to the next question. Another might need a timer, a few buttons, and some randomization.
Those requirements don't automatically justify a game engine.
For simple browser games, the browser already provides a lot of what you need.
HTML, CSS and JavaScript Can Go a Long Way
The basic combination is surprisingly capable.
HTML provides the structure of the page. CSS controls the visual presentation and responsive layout. JavaScript handles the interaction and game logic.
That combination was enough for many of the interactive experiences I wanted to create.
This also made the project easier for me to understand. Instead of learning a large development environment before I could build anything, I could take one problem at a time and learn the JavaScript or browser feature required to solve it.
That approach was much less intimidating.
Understanding Events Changed Everything
One of the most important concepts I encountered was the browser event system.
A player clicks a button. They press a keyboard key. They select an answer. They interact with something on a touchscreen.
JavaScript can listen for these actions and respond.
For example, a simple interaction can look like this:
button.addEventListener("click", () => {
checkAnswer();
});
There isn't much code here, but understanding what is happening is important. The browser waits for an event, JavaScript receives it, and the application responds.
Once I understood that pattern, many game interactions became easier to think about.
Timers Are Simple Until You Start Testing Them
Timers are another feature that looks trivial until you actually build something around them.
A timed math game, typing game, countdown activity, or classroom timer needs to know when the timer starts, when it stops, and what happens when the time reaches zero.
A simple implementation can use JavaScript's built in timing functions.
let timerId;
function startTimer() {
clearInterval(timerId);
timerId = setInterval(() => {
updateTimer();
}, 1000);
}
function stopTimer() {
clearInterval(timerId);
}
The important lesson for me wasn't memorizing setInterval().
It was understanding that every temporary process needs a clear lifecycle. If something starts, you need to know when it should stop.
That principle applies to much more than games.
Randomness Makes Games Replayable
A lot of educational games become more useful when the experience changes each time someone plays.
A math game can generate different questions. A word game can select different words. A memory activity can shuffle cards. A quiz can select questions from a larger pool.
JavaScript provides simple tools for random selection.
const index = Math.floor(Math.random() * items.length);
const item = items[index];
The interesting part comes after that.
You need to think about whether something can repeat too often, whether the difficulty remains appropriate, and whether the player is actually getting a different experience.
For example, one of the quizzes currently available on GamesMom selects questions from a larger pool and shuffles both the questions and answer positions between rounds.
That turns a simple randomization function into an actual product decision.
Not Every Game Needs Canvas
Before working on the project, I assumed that interactive games would naturally require Canvas.
That isn't always the case.
If a game is primarily made up of questions, text, buttons, cards, scores, and simple interactions, ordinary HTML elements can work very well.
JavaScript can update the page when something changes:
scoreElement.textContent = score;
questionElement.textContent = currentQuestion;
For many educational games, this approach is perfectly reasonable.
It also has a practical advantage. Normal HTML elements can work naturally with browser features such as text selection, zooming, keyboard interaction, and accessibility tools.
For the types of games I was building, I didn't need to make everything a custom graphical surface.
Mobile Testing Changed My Thinking
One of the biggest differences between building a normal website and building browser games is interaction.
A button that works well with a mouse may not work well on a phone.
A small card can be easy to click with a cursor and frustrating to tap with a finger.
As I tested games on different screen sizes, I became much more aware of touch targets, spacing, responsive layouts, font sizes, and the amount of information displayed on the screen.
GamesMom is intended to work across phones, tablets, laptops, and classroom displays, so responsive design became part of the development process rather than something to consider at the end.
Accessibility Is Part of the User Experience
I also learned that building games for children changes the way you think about accessibility.
An interactive element needs to be easy to identify and use. Text needs to remain readable. Controls should not depend entirely on a mouse. The interface needs to remain usable across different screen sizes.
This doesn't require an advanced accessibility framework.
It requires paying attention.
Keyboard navigation, visible focus states, readable typography, appropriate contrast, sensible touch targets, and simple interactions can make a significant difference.
The more I worked on the project, the more I realized that accessibility isn't something you bolt onto a finished website. It is part of the interface from the beginning.
Performance Becomes More Important as the Site Grows
A single game can hide a lot of inefficiency.
When you start building a larger collection of browser games, those decisions become more important.
Images need to be appropriately sized. JavaScript should do useful work rather than unnecessary work. Pages shouldn't load resources that the visitor doesn't need. Animations shouldn't exist simply because they look impressive.
This is one reason I liked keeping the individual games relatively focused.
Someone playing a typing game shouldn't need to load the resources required by an unrelated memory game.
Keeping experiences focused can improve both the development process and the experience for the person using the site.
Reusable Code Is Useful, But There Is a Limit
One of the biggest lessons from building multiple games was learning where reuse makes sense.
Some functionality naturally repeats. Scores, buttons, timers, result screens, and common interface elements can often follow the same patterns.
But the actual experience of each game should still feel appropriate to what the player is doing.
If you make everything too reusable, you can end up forcing completely different games into the same structure.
The goal isn't to make every game identical.
The goal is to avoid solving the same technical problem repeatedly.
What Building Games Taught Me About Development
The biggest lesson wasn't a particular JavaScript function or browser API.
It was learning how to break unfamiliar technical problems into smaller problems.
Coming from digital marketing, I didn't approach GamesMom with years of software engineering experience. I approached it by learning what I needed, testing different approaches, reading documentation, using development tools, and fixing problems as they appeared.
That experience changed how I look at websites.
As a marketer, it is easy to think about a website primarily in terms of traffic, rankings, conversions, content, and acquisition.
Building the product myself made me think more about what happens underneath those metrics.
Performance affects the user experience. Interface decisions affect engagement. Accessibility affects who can use the product. Architecture affects how easily a site can grow.
Those things are connected.
What I Would Do Differently
If I started again, I would spend more time defining the common building blocks before creating a large number of games.
I would also test on mobile devices earlier and establish accessibility and performance standards before the number of pages and games became large.
Most importantly, I would avoid adding technology simply because it is popular.
If a simple JavaScript solution works, there is no prize for making it complicated.
If a project eventually reaches the point where a framework or game engine solves a real problem, then introduce it.
The technology should respond to the requirements of the product.
You Don't Have to Be a Developer to Start Building
I wouldn't describe myself as a developer because that isn't my profession.
But building GamesMom taught me that the barrier between marketing and development is much lower than I previously thought.
You don't need to know everything before starting a technical project.
You need to be willing to learn enough to solve the next problem.
That might mean learning JavaScript today, responsive web design tomorrow, and performance optimization next week.
The process is incremental.
You don't have to become an expert in everything before you build your first useful thing.
I started GamesMom because I wanted to create free educational games and learning activities that children could use directly in a browser. Along the way, the project became an unexpected education in web development.
I learned that HTML, CSS, and JavaScript can go surprisingly far when the problem is relatively simple. I learned that good mobile experiences require more than making a desktop layout responsive. I learned that accessibility and performance need to be considered early. Most importantly, I learned that adding more technology isn't automatically the answer to a technical problem.
Sometimes the best solution is the simplest one you understand well enough to improve.
And that may be the most useful thing I took away from building browser games as a marketer rather than a developer.
