I Thought I Was Building One 2048 Game. It Turned Into Three.

I originally only wanted to make one small browser game.

The idea was simple: keep the familiar rules of 2048, but replace the numbered tiles with cupcakes.

I have always liked how little explanation 2048 needs. You open it, move a few tiles, and within seconds you understand what is happening. The original 2048 project is a good example of how far a simple game mechanic can go without needing much around it.

What I wanted to change was not the rule itself, but the feeling of progression.

Instead of watching 2 become 4, then 8, then 16, I wanted one cupcake to turn into another cupcake, and eventually into something much more elaborate.

That became 2048 Cupcakes.

At that point, I wasn't thinking about reusable architecture or building a collection of games. It was just one page.

Most of my time went into things that looked small from the outside: getting tile movement to feel right, making merges easy to read, handling swipes properly on mobile, saving the board, and making sure the game still felt comfortable at different screen sizes.

None of those things were especially difficult on their own.

There were just a lot of them.

The second version changed the project

Once the cupcake version was working, I had another idea.

What if the same game used Doge images instead?

My first instinct was to copy the project, replace the artwork, change a few strings, and move on.

I almost did that.

Then I looked at what I would actually be copying:

• movement logic
• merge rules
• score calculation
• keyboard controls
• touch controls
• animations
• game-over detection
• local saving
• sound
• hint logic

Almost everything would remain the same.

Only the images, names, and presentation were really changing.

That was the point where I stopped thinking of it as one cupcake game and started separating the game itself from the theme.

The core does not need to know whether a tile represents a cupcake, a dog, a princess, or a number.

It only needs to understand the board.

A tile has a value. Tiles move. Matching values merge. The score changes. A new tile appears. Eventually there may be no legal moves left.

Everything visual can sit somewhere else.

Once I had that separation, Doge 2048 became much easier to build.

The game logic stayed almost untouched. I could focus on the Doge progression, the images, and how the theme felt instead of rebuilding the mechanics.

Then I tried a third version: Princess 2048.

That was probably the moment I knew the separation had actually worked.

By the third theme, adding another game was no longer mostly a programming task. Most of the work had moved toward artwork, progression, naming, and presentation.

What started as one page had quietly become a small themed 2048 collection.

I didn't want a backend just because I could build one

Another decision I kept throughout the project was to avoid adding a backend unless there was a real reason for one.

A game like this needs to remember a few things:

• the current board
• the score
• the best score
• the number of moves
• sound preferences
• display preferences

It would be possible to create accounts, authentication, an API, and a database to save all of this.

But I couldn't find a good reason to ask someone to register just so a 4×4 board could survive a page refresh.

The browser already gives us localStorage, so that is enough for the current version.

The tradeoff is obvious: progress stays in that browser instead of following the player across every device.

For this kind of game, I am comfortable with that.

Someone can open the page and start playing immediately. There is no login form and no network request required just to restore a game.

It was a useful reminder that more infrastructure does not automatically mean a better product.

Touch controls were more annoying than expected

Keyboard controls are easy.

An arrow key gives you a direction. WASD does the same thing.

Touch input sounded equally simple at first.

Record where the finger starts, record where it ends, work out the direction, and move the board.

In practice, it needed much more tuning.

If the swipe threshold is too low, an ordinary tap can become an accidental move.

If the threshold is too high, a deliberate short swipe feels like the game ignored you.

Diagonal movement also needs to be interpreted in a predictable way, and mobile browsers have their own scrolling behavior that can conflict with the game.

It made me think more about the difference between something being technically correct and something feeling correct.

The board can move exactly as the code intended and still feel bad to play.

That kind of detail ended up mattering more than adding another large feature.

The move guide became its own little problem

Later, I started experimenting with a move guide.

The naive approach is easy: test the four directions and choose whichever move gives the highest immediate score.

It is also not very good.

A move that creates a nice merge right now can leave the board in a terrible position two or three turns later.

So the guide needs to care about more than the next score.

Things like empty spaces, board smoothness, where the largest tiles sit, and how many future moves remain all start to matter.

Once the search becomes deeper, computation time becomes noticeable.

Doing too much of that work on the browser's main thread can interfere with animation and user input.

That led me to Web Workers.

The current board can be sent to a worker, the heavier search can run separately, and the suggested move can come back without making the interface feel stuck.

I did not expect a little 2048 game to lead me there when I started.

That has probably been the recurring pattern with this project.

The rules are simple.

Most of the work is somewhere else.

It is in how a swipe feels.

It is in whether the game remembers where you left off.

It is in whether a second theme means copying hundreds of lines of code.

It is in whether a helper feature makes the whole interface stutter while it is thinking.

The third theme was the real test

The first theme could not tell me whether my structure was reusable.

There was nothing to reuse yet.

The second theme exposed the duplication.

That gave me a reason to refactor.

The third theme told me whether the refactor was actually useful.

By the time I was working on Princess 2048, I wasn't rebuilding movement, saving, scoring, touch handling, or the move guide.

Those parts were already there.

That was much more satisfying than designing a generic system before I knew what needed to be generic.

If I had tried to predict every future theme while making the first game, I probably would have created abstractions for problems that never appeared.

Building the second version showed me the real boundary.

I'm still trying to keep it small

There are plenty of directions this project could go.

I could add accounts, cloud saves, global leaderboards, daily challenges, multiplayer, a backend API, or a larger frontend framework.

Some of those might make sense later.

Right now, the main experience still works with HTML, CSS, and vanilla JavaScript.

I like that.

The goal isn't to use as little technology as possible.

It is to avoid adding technology before there is a problem that actually needs it.

For now, I would rather spend time improving how the games feel, experimenting with themes, and watching how people actually use them.

The most useful lesson from this project turned out to be fairly simple:

Build one real version.

Build another variation.

Notice what actually repeats.

Then make that part reusable.

Sometimes the second version tells you what the first one was really supposed to become.
