Stimulation Clicker: the website that overloads you on purpose

Stimulation Clicker is a free browser game by Neal Agarwal in which a single button slowly summons the entire modern internet onto one screen at once: a true crime podcast, Subway Surfers footage, a Duolingo lesson, bouncing DVD logos and a shouting video game announcer, all running together until the page is pure noise. It is a clicker game about clicker games, and a pointed joke about what it feels like to be online in 2025.

In brief

• A clicker game released on 6 January 2025 at neal.fun, where clicking earns Stimulation Points that buy upgrades, and every upgrade adds another layer of noise.
• The upgrades are real internet artefacts stacked on top of each other: a 45 minute true crime podcast, Subway Surfers gameplay, Duolingo questions, a DVD screensaver, and a Halo announcer calling out your clicks.
• It is a satire of the overstimulated, engagement driven web, and it ends, once you have bought everything, with a single quiet shot of the ocean.

What Stimulation Clicker is

On the surface, Stimulation Clicker looks like any idle game. There is a big button in the middle of the screen and a simple instruction: click it. Each click earns one Stimulation Point. Points buy upgrades, upgrades earn more points per second, and the counter climbs. Anyone who has touched Cookie Clicker or a mobile idle game will recognise the shape of it within seconds.

The twist is what the upgrades actually do. In a normal clicker, an upgrade is an abstract number: a bigger cursor, a faster factory, a higher multiplier. In Stimulation Clicker, every upgrade is a piece of the real internet, and buying it drops that piece permanently onto your screen. The podcast does not just boost your income. It starts playing. The Subway Surfers footage does not sit in a menu. It runs in the corner for the rest of the session. The game does not describe overstimulation. It performs it, on you, one purchase at a time.

By the halfway point the screen is a collage of competing media, all demanding attention, none of it pausable. The button is still there somewhere underneath, and you are still clicking it, because that is the deal you made. Stimulation Clicker is the rare game whose difficulty is not enemies or timing but simply the state it puts your senses in.

How the game works

The core loop is deliberately familiar. You click the central button to earn Stimulation Points. You spend those points on upgrades from a list, each of which either increases how many points a click is worth or generates points passively over time. Cheaper upgrades unlock more expensive ones, and the numbers grow quickly enough that the early game feels brisk rather than grindy.

What sets the pace is not the maths but the sensory cost of progress. Each upgrade you buy is a decision to make the screen louder and busier in exchange for a faster counter. There is no volume slider that fixes it and no way to buy a quieter path. The only way forward is more. That single design choice turns an ordinary numbers game into something closer to an experiment about tolerance.

There is also no save system. Progress cannot be carried between sessions, so if you close the tab, the whole overwhelming edifice vanishes and the next visitor, or the next you, starts again from one lonely button. For a genre built on months long persistent progress, throwing all of it away on refresh is its own small act of satire. It also quietly changes how you play. Knowing nothing will be kept, you stop optimising and start simply experiencing the thing, which is exactly the frame the game wants you in.

The stimulations it piles on

The specific upgrades are what people remember, because Agarwal did not gesture vaguely at internet clutter. He built the clutter. Among the layers the game stacks onto the screen are these.

• A full true crime podcast, reportedly a 45 minute original recording performed by voice actors, murmuring away in the background as if you had left something playing and forgotten it.
• Gameplay footage of Subway Surfers, the endless runner whose looping mobile action has become internet shorthand for content designed to occupy the eyes while another video plays.
• Duolingo questions that pop up and quiz you, complete with the guilt loop of a language app that wants its daily minute.
• A DVD screensaver logo bouncing across the page, forever almost hitting the corner.
• Voice lines from Jeff Steitzer, the announcer whose Halo multiplayer callouts are burned into a generation of memories, now narrating your clicking.
• Recordings of streamers and influencers talking directly at you, the ambient chatter of a hundred open tabs compressed into one.

Each of these is recognisable on its own. The joke is the sum. No single element is unusual in a modern browsing session, and that is exactly the point: the game only assembles things you have almost certainly already had running at the same time, and asks you to notice how absurd the stack has become.

There is craft in the ordering, too. The stimulations arrive one at a time, cheap ones first, so the escalation is gradual enough that you keep saying yes. No single purchase feels like the one that tips the screen into chaos, and yet somewhere along the line it does. That creeping quality is the most true to life thing about it, because nobody chooses an overwhelming internet in one decision. They arrive at it the way you arrive at the late game here, one reasonable upgrade after another.

What it is really about

Agarwal has said the game grew out of wanting to capture the experience of being terminally online, and the finished piece reads as commentary on how the modern web keeps people engaged. Sites and apps compete for a finite pool of attention by adding stimulation: autoplaying video, infinite feeds, notifications, streaks, sounds. Each addition makes sense on its own terms and is defensible as a single feature. Stimulation Clicker simply refuses to stop at one, and lets the logic run to its conclusion.

The result lands harder than a lecture would, because the player is complicit. Nobody forces you to buy the podcast or the bouncing logo. You choose each layer, one click at a time, in exchange for a bigger number, which is precisely the bargain the attention economy offers every day. By the end you are not a victim of the noise so much as its author, which is a far more uncomfortable and more honest thing to be.

Critics picked up on that edge. One writer called it a funny but bruising commentary on engagement tactics. Another described it as a remarkable rendering of how digital life has gone off the rails. A third, only half joking, called it a terrifying art project. It is unusual for a free browser toy to be discussed in those terms, and that gap between the humble format and the weight of the subject is a large part of why the game travelled.

How it spread

Stimulation Clicker did what the best neal.fun releases tend to do: it escaped its own website. Within days of launch it was being clipped, screen recorded and passed around, precisely because it is so hard to describe and so easy to show. A screenshot of the mid game, with five kinds of media fighting for the same square of screen, communicates the entire joke instantly, and a screen recording with the sound on is even better. The game is, in a sense, built to be shared, which is a neat irony for a piece about the attention economy.

That shareability is not an accident of the subject so much as a feature of how Agarwal works. His pieces tend to compress a whole idea into a single screen you can grasp at a glance, which makes them ideal fuel for the same feeds and group chats the game is gently mocking. Stimulation Clicker went out into exactly the environment it depicts and thrived there, which is either the final joke or the proof of concept, depending on how cynical you are feeling.

Who made it

Stimulation Clicker is the work of Neal Agarwal, the creator behind neal.fun, a site that has spent years turning single ideas into small, self contained interactive pieces. Agarwal has a particular talent for taking one concept and building it out just far enough to become a shared internet moment, then leaving it free and open for anyone to try.

His back catalogue explains why Stimulation Clicker arrived with an audience already waiting. The Password Game asked players to satisfy an escalating list of increasingly deranged password rules. Infinite Craft let people combine elements endlessly to discover new ones. The Deep Sea, which this blog has written about before, invited a slow scroll from the ocean surface down to the trench floor. Each is a different flavour of the same instinct: take a simple interaction and follow it somewhere strange. Stimulation Clicker points that instinct at the internet itself, which may be why it feels like the most self aware thing he has made.

How it was built

By Agarwal's account the game took around four months to make, and its lineage is clear. The mechanical skeleton borrows from Cookie Clicker, the game that made idle clicking a genre, and from Upgrade Complete, an older browser game that turned the act of buying upgrades into its own joke by charging you to upgrade the menus and the play button. Stimulation Clicker inherits that self aware streak and pushes it toward sensory overload rather than economic absurdity.

The idea itself is older than the build. Agarwal has said it dates back to the COVID lockdown period, when a great many people were spending more of their waking lives inside a browser than ever before, often with several sources of stimulation running at once. The game is in that sense a document of a specific moment, when being online stopped being an activity and became closer to an environment. That the finished piece landed years later, when the habits it describes had only deepened, gave it an accidental timeliness.

How it ends

Most clicker games do not really end. They stretch toward ever larger numbers with no finish line, which is part of what makes them so sticky. Stimulation Clicker is different. There is a finite list of upgrades, and once you have bought all of them, the game is over.

The ending is the sharpest joke in the whole piece. After the cacophony of podcasts and announcers and bouncing logos, buying the last upgrade triggers an end credits scene set at the ocean: quiet water, and nothing demanding anything of you. After all that noise, the reward is silence. It is the one moment the game stops performing overstimulation and instead offers its opposite, and it makes the preceding chaos feel, in hindsight, like a held breath.

That structure, a clear build to a single calm release, is unusual for the genre and gives the game a shape closer to a short story than a toy. It is the difference between a joke that repeats and a joke that resolves, and it is why people who finish it tend to describe the ending rather than the middle.

A browser toy that argues with the browser

Stimulation Clicker belongs to a small but persistent tradition of websites built to comment on the web from the inside. What makes that tradition powerful is that the critique is native to the medium. The game does not describe the problem of the overstimulated internet in an essay you can nod along to and close. It reproduces the exact mechanics, the autoplaying video, the stacked media, the endless list of upgrades that each seem reasonable, inside the very browser tab where you experience those things every day. The argument is felt rather than read, which is why it sticks.

Being free, open and instantly shareable matters here too. A piece of media criticism reaches the people who already seek out media criticism. A browser toy that goes viral reaches everyone else, the people actually living inside the thing it describes, and it reaches them through the same feeds and group chats it is quietly mocking. That is a rare and valuable trick. The interactive one idea web toy remains one of the last formats where a single person can ship a complete cultural statement without a studio, a store or a subscription, and have millions of people try it within a week. Stimulation Clicker is a particularly sharp example, but it is part of a larger, healthy habit: the web occasionally turning around to take a hard, funny look at itself, using nothing more than the tools it hands to anyone with a text editor and a domain name.

Why it belongs in the boring websites canon

Stimulation Clicker fits neatly among the small, single purpose sites this blog collects. It does exactly one thing, it does it in a browser tab, there is nothing to install and nothing to buy, and it commits completely to its premise. It also belongs to a long tradition of websites that are secretly about the web itself, holding up a mirror to the medium they run in.

If the game leaves you wanting the opposite sensation, the quiet end credits rather than the noise, the blog's guide to relaxing and ambient websites is full of calmer single purpose corners of the internet to wander into next. A site that piles the whole internet onto one screen and a site that asks nothing of you at all turn out to be two sides of the same small, hand made web, the one that still makes things for the pleasure of making them. You can find more of it across the Boring Websites hub.
