What is Particle Clicker?

Particle Clicker is a free browser-based incremental ("clicker") game about running a particle-physics lab. It was created during the CERN Webfest 2014 and borrows its core loop from Cookie Clicker: you click a detector to generate events, convert that activity into data, and reinvest it to grow.

How it plays

According to the game's own page, the loop has three currencies and a small team-building layer:

  • Data — produced by clicking the detector and by the workers you hire.
  • Funding — money spent on workers and upgrades.
  • Reputation — earned through research, which you unlock and level up as you progress.
  • HR — you hire staff whose output is measured in data per second, the classic idle-game growth curve.
  • Upgrades and research — permanent boosts and new research lines that raise your yield.
  • Achievements and statistics — tracked progress, including total clicks and data spent versus collected.

It is explicitly framed as a "historic journey through modern particle physics," so the research names and milestones reference real physics topics rather than generic fantasy upgrades. The page lists version 0.9 and labels itself a pre-release.

Who it suits

  • Curious non-physicists who want a light, playful entry point to particle-physics vocabulary.
  • Fans of idle games who enjoy optimizing output-per-second and chasing achievement lists.
  • Teachers or outreach organizers looking for a low-stakes classroom or event activity.

It is not a simulation or a teaching tool with structured explanations; the physics is flavor wrapped around a clicker mechanic.

Practical caveats

The page notes the game runs best in landscape orientation, that mobile play is landscape-only, and that the event display's performance depends heavily on your hardware. Progress is saved with a visible save timestamp and a manual "Save now" option, so if you care about a long run, save deliberately.

Next step: if you want to try it, open Particle Clicker in a desktop browser in landscape view, click the detector a few times to feel the loop, then spend your first funding on workers rather than upgrades—steady data-per-second income usually compounds faster early on.

How does the game simulate a particle physics research career?

Particle Clicker turns a research career into an incremental clicker: you start by clicking a detector to generate events, convert those into data, and reinvest data and funding into people, upgrades and research that raise your output. The page describes it as a historic journey through modern particle physics, borrowing the loop from Cookie Clicker.

The career loop on the page

  • Detector clicks → events → data. Clicking the detector is the entry-level "work"; the counter shows data collected and spent.
  • HR and staff. Named workers each have a hire count, a description and a data-per-second rate, so your career grows by building a team rather than only clicking.
  • Funding. Money is a separate currency with its own collected/spent statistics, used alongside data for upgrades.
  • Research and reputation. Research items are hidden as "?????" until unlocked, each with a level, a reputation yield and a data cost — the progression ladder that stands in for a scientific portfolio.
  • Upgrades. Purchasable items with an effect and a cost, the standard way to multiply your existing operation.
  • Achievements and statistics. Progress is tracked against an achievement list with timestamps, plus totals for clicks, data and money — a career record rather than a single score.

A concrete example: a player who enjoys optimization will spend early data on staff to raise passive data per second, then save for research that yields reputation, while a casual player may just keep clicking the detector. The trade-off is breadth versus depth: hiring widely raises steady income, while concentrating on research and upgrades changes what your lab is known for. The game is explicitly a pre-release (version 0.9), designed for landscape orientation, and the event display's performance depends on your hardware — relevant if you plan to play on a low-end phone or an older laptop.

For a next step, treat the statistics panel as your lab notebook: compare data spent against data collected after a session to see whether hiring or upgrades gave the better return, then adjust. The project's source and issue tracker are on GitHub, and the game itself is at Particle Clicker.

What upgrades and research options are available in Particle Clicker?

Particle Clicker's upgrades and research are the two main ways to turn clicking into steady progress. The game itself describes research as generating reputation and upgrades as purchasable effects tied to your detector, staff and data output; the page also shows HR hiring alongside them, so the three systems work together rather than as separate mini-games.

What each system does

  • Research: You unlock research items in sequence; each has a name, a level and a description, and produces reputation. Early items are hidden as "?????" until you reach them, so the exact list is something you discover as you play rather than read up front. Research is the long-term progression layer.
  • Upgrades: These are one-off purchases with a stated effect and a cost in funding. They modify how your detector, staff or data production behave, so they are the short-term efficiency layer.
  • HR (hiring): Staff have a description, a hiring cost and a data-per-second rate. They are the passive-income layer that makes research and upgrades affordable without constant clicking.

A typical play pattern

A new player clicks the detector to generate events, spends the resulting data on HR to build passive data per second, and uses funding to buy upgrades that raise that output. Reputation from research then gates access to stronger research. The practical decision is whether to spend funding on an upgrade now or save it for a hire that compounds over time; upgrades pay off fastest when you are actively clicking, while hires pay off when you leave the game running.

Trade-offs to weigh

Upgrades are immediate but finite, so buying them early smooths the opening and buying them late wastes their benefit. Research is slower but unlocks reputation, which is the metric the game tracks separately from data and funding. Staff scale with how long you play, so they suit longer sessions and are less useful for a quick visit.

Particle Clicker is a CERN Webfest 2014 project inspired by Cookie Clicker, available at Particle Clicker; the page notes it is a pre-release (version 0.9) and runs best in landscape orientation. For a concrete next step, open the Research tab first and note which items are still hidden, then check whether your current funding is better spent on the next upgrade or on one more hire.

How do I save my progress and restart the game?

Particle Clicker saves your progress automatically, and you can also save manually or restart from the same top menu. The page shows a "Saved: {{ lastSaved | date: 'H:mm' }}" indicator with a "Save now" button and a "Restart" option next to it.

Saving progress

  • Automatic saving: The game tracks progress on its own; the timestamp next to "Saved" tells you when it last saved.
  • Manual save: Click "Save now" before closing the tab or switching devices, especially if you've just made a big purchase or reached a new research level.
  • What's preserved: The interface tracks your data, reputation, funding, staff hires, upgrades, research levels and achievements, so a save captures the full run rather than just the click count.

Restarting the game

  • "Restart" in the top menu resets the run. Use it deliberately: it's the option to reach for when you want a clean slate, not a quick undo.
  • Before restarting, note that progress is tied to the browser session shown by the save indicator. If you're unsure whether a restart is what you want, save first so you have a timestamp to compare against, then restart and confirm the counters have reset.

Practical scenario

If you're playing on a laptop and plan to continue on a phone, click "Save now" before leaving, then reopen the game in landscape orientation on the mobile device. The game states it runs best in landscape mode, and mobile play requires landscape orientation, so rotating the device is part of the routine rather than a troubleshooting step.

The game is a pre-release (version 0.9), and the authors ask that bugs be reported through GitHub issues. If a save doesn't seem to stick, that's the channel to use. For background on the project, see Particle Clicker.

Can I play Particle Clicker on mobile devices?

Yes. Particle Clicker runs in a mobile browser, with one important condition: the game states that it can only be played on a mobile device in landscape orientation. Rotate your phone sideways and it should work; the page also notes that the event display's performance depends heavily on your hardware, so older or low-end phones may feel sluggish.

What to expect on a phone

  • Controls: The core loop is tapping the detector to generate events, so a touchscreen suits it naturally; the rest is menu-driven (Research, HR, Upgrades, Achievements, Statistics).
  • Saving: The interface shows a "Saved" timestamp and a "Save now" button, so use the manual save before closing the tab rather than relying on the browser staying open.
  • Version: It is labelled a pre-release (version 0.9), and bug reports are directed to GitHub issues, so occasional glitches are plausible.

Practical next step

If the page loads but the game looks cramped or unresponsive, check that rotation lock is off, then reload in landscape. For a quick comparison of what the game is, it borrows its structure from Cookie Clicker but frames progress as a historic journey through modern particle physics, made during the CERN Webfest 2014; the original Cookie Clicker shows the genre template it follows. The game's source is published on GitHub under an MIT licence, which matters if you want to study or adapt it rather than just play.

Where can I report bugs or contact the developers?

Report bugs through the project's GitHub issues page, which the game's About section names as the place to file bug reports. For general contact, email the developers at [email protected]. The About section also says you can reach them via GitHub, and the game's source is published there under an MIT license.

Both channels are listed on Particle Clicker's own About panel, so you don't need to hunt elsewhere.

A practical next step: before filing, note your device, browser and orientation, since the game states it runs best in landscape and warns that the event display's performance depends heavily on your hardware. Include those details in the issue so the developers can tell a genuine bug from a slow device.

Why Particle Clicker Requires Landscape Mode and May Run Slowly

Particle Clicker only supports mobile play in landscape orientation, and its event display performance depends heavily on your hardware. The game's own About panel states both points directly: mobile devices must be held in landscape, and the event display "may rely heavily on your hardware." So if you see a rotate-your-device prompt on a phone, that is expected behavior, not a bug. If the game stutters, the cause is most likely the graphical event display rather than the click-and-upgrade logic.

Why landscape is required on mobile

The game was built during the CERN Webfest 2014 as a browser-based incremental game, and its interface is wide: a detector area, a data/reputation/funding bar, and panels for Research, HR, and Upgrades. The About panel says the game "runs best in landscape mode," and a dedicated notice tells mobile players they "can only play Particle Clicker on your mobile device in landscape orientation."

In practice:

  • On a phone in portrait: expect the orientation notice instead of the game. Rotating the device to landscape is the fix.
  • On a phone in landscape: the game loads, but the layout is still cramped compared with desktop.
  • On desktop: landscape is the natural orientation, so no prompt appears — but the "runs best in landscape" advice still reflects the intended wide layout.

This is a design constraint of the pre-release (version 0.9), not a setting you can toggle.

Why the game can run slowly

The About panel separates two things: the game logic and the event display. The event display — the visual representation of particle events tied to your detector — is the part flagged as hardware-dependent. That means:

Symptom Likely cause What to try
Choppy or laggy visuals around the detector Event display taxing your GPU/CPU Close other tabs and apps; try a desktop browser
Game feels slow on an older phone Hardware below what the display needs Play on a more capable device or desktop
Prompt to rotate instead of gameplay Portrait orientation on mobile Rotate to landscape
Layout looks broken or cut off Narrow viewport Use landscape, or a wider window on desktop

The game does not publish minimum hardware requirements, so "slow" is relative to your device. The honest guidance is: if the event display is the bottleneck, move to a stronger device rather than hunting for a graphics setting — none is documented.

Practical steps to get a smooth session

  1. Open the game at particle-clicker.web.cern.ch in a modern browser.
  2. On mobile, rotate to landscape before or right after loading. If you see the orientation notice, rotation is the only supported fix.
  3. On desktop, maximize the window so the wide layout has room.
  4. Reduce background load — close other tabs, streaming, or heavy apps — since the event display competes for the same hardware.
  5. Verify progress is saving. The interface shows a "Saved: [time]" indicator and a "Save now" button. If performance problems make you reload or switch devices, use "Save now" first. Note the game also has a "Restart" option, so avoid clicking it by accident.
  6. If something is genuinely broken — not just slow — report it through the GitHub issues link in the About panel, which the developers explicitly request for bugs in this pre-release.

What counts as a bug versus a limitation

  • Expected, not a bug: the landscape-only prompt on mobile; slower event display on weaker hardware; the pre-release "Version: 0.9" label.
  • Worth reporting: the game failing to load, the save indicator not updating, controls not responding in landscape, or visual glitches beyond ordinary lag. Use GitHub issues, as the About panel asks.

The game is free to play in the browser and its source is available on GitHub under an MIT license, so the landscape requirement and hardware sensitivity are properties of the published build rather than paywalls or account restrictions.

What Is Particle Clicker?

Particle Clicker is a free browser-based incremental game about particle physics, built during the CERN Webfest 2014 and openly inspired by Cookie Clicker. You play by clicking a detector to generate events, then spend the resulting data and funding on research, staff, and upgrades that push your lab through a historic journey across modern particle physics. It is best suited to people who want a short, low-pressure clicker with a physics theme rather than a deep simulation.

What you actually do

The core loop is simple and follows the standard incremental pattern:

  1. Click your detector to generate events, which produce data.
  2. Spend data on research — each research item yields reputation and has a data cost.
  3. Hire staff (HR) — workers produce a set amount of data per second and cost funding.
  4. Buy upgrades — upgrades modify your output and cost funding.
  5. Track progress through achievements and statistics screens.

The page presents three running totals: Data, Reputation, and Funding. Research items show as ????? until you reach their level, so part of the experience is unlocking the physics story as you go.

Key mechanics at a glance

Element What it does Cost / output
Detector clicks Generate events and data Manual input
Research Yields reputation; advances the physics narrative Costs data
Workers (HR) Produce data automatically Cost funding; produce data per second
Upgrades Change your output Cost funding
Achievements Track milestones with timestamps No cost
Statistics Clicks, data spent vs. collected, money spent vs. gathered No cost

The game also saves automatically — the interface shows a "Saved" timestamp and a Save now button, plus a Restart option.

Practical things to know before you start

  • Play in landscape orientation. The game states it can only be played on mobile in landscape, and it runs best in landscape generally.
  • It is a pre-release (version 0.9). The authors ask that bugs be reported via GitHub issues.
  • Performance depends on your hardware. The event display may be demanding on weaker devices.
  • It is a browser game. No install is described; you open the site and play.
  • Source and contact are public. The code is on GitHub under an MIT license, and the authors list a group email and GitHub as contact channels.

Who made it and why it matters

Particle Clicker was created by Gabor Biro, Igor Babuschkin, Kevin Dungs, Tadej Novak, and Jiannan Zhang during CERN Webfest 2014. It is built with AngularJS, Bootstrap, Fontawesome, jQuery, retina.js, and fastclick.js. Its value is mostly educational and playful: it turns the history of modern particle physics into a progression system you unlock by clicking, which makes it a friendly entry point for newcomers and a small piece of CERN web culture for everyone else.

If you want a quick, free clicker with a real physics theme and don't mind a pre-release build, open the site and start clicking the detector. If you need a polished, content-complete game, treat this as a short curiosity rather than a long-term commitment.

How Particle Clicker Gameplay Works

Particle Clicker is a browser-based incremental game where you click a particle detector to generate events and data, then spend those resources on staff, upgrades, and research to grow your lab. It was built during the CERN Webfest 2014 and borrows its core loop from Cookie Clicker. The game is a pre-release (version 0.9), runs best in landscape orientation, and on mobile devices only plays in landscape.

The Core Loop

The game has three interlocking resources:

Resource How you get it What it's for
Data Clicking the detector, plus production from hired staff Buying staff and upgrades
Reputation Generated by research Unlocking and advancing research areas
Funding Earned through gameplay progression Hiring staff and buying upgrades

The detector is the starting point: each click generates events and produces data. Early on, clicking is your only income; the game's Statistics panel tracks total clicks, data spent versus collected, and money spent versus gathered, so you can see how efficiently your lab is running.

Staff, Upgrades, and Scaling Production

Hired workers each produce a set rate of data per second, shown alongside their cost. Buying more of a worker increases your passive data income, which gradually replaces manual clicking as your main source. Upgrades modify your operation — each has a name, description, effect, and cost — and are purchased with funding. The practical rhythm is: click to accumulate data, spend data on staff to raise per-second output, and spend funding on upgrades that make each worker or click more effective.

Research and Reputation

Research is the progression layer. Each research area has a level and a description, and research yields reputation. Areas you haven't reached yet display as "?????" until unlocked, so the research tree doubles as a map of what's ahead. Reputation feeds back into research, creating a second growth loop alongside data production. Achievements track milestones with timestamps, and a progress counter shows how many you've earned out of the total.

Saving and Practical Notes

The game autosaves — the header shows the last save time and offers a "Save now" button, plus a restart option. It's built with AngularJS, Bootstrap, and jQuery, and the source is available on GitHub under an MIT license. The about page notes that event-display performance depends heavily on your hardware, so on older machines expect the visuals to be the bottleneck rather than the game logic. Bugs are reported through GitHub issues, and the team can be reached at [email protected].

If you want a quick sense of whether the game suits you: it's a short-session idle game best played in a landscape browser window, where the fun comes from watching data-per-second climb as you layer staff, upgrades, and research.

How to Get Started and Progress in Particle Clicker

Particle Clicker is a browser-based incremental game (a pre-release, version 0.9) built during the CERN Webfest 2014. To start, open the game, click the detector to generate events and earn data, then reinvest data and funding into HR, upgrades, and research to grow your data-per-second rate and reputation. Play in landscape orientation and save regularly, since the game notes it runs best that way and progress is tracked through manual and timed saves.

Starting Out: The Core Loop

The game screen is organized around a few panels: your detector, Data, Reputation, Funding, HR, Upgrades, Research, Achievements, and Statistics.

  1. Click the detector. The page describes it as "Your detector. Click on it to generate events." Each click adds to your data total, shown as Data in the lab state.
  2. Watch your counters. Data, Reputation, and Funding are displayed at the top of the lab view. Statistics track clicks, data spent versus collected, and money spent versus gathered.
  3. Reinvest early. Your first data should go toward the cheapest available workers or upgrades so that data accumulates even when you are not clicking.

What Each Resource Does

Resource How you get it What it is for
Data Clicking the detector; workers producing data per second Paying for research and other data-cost items
Funding Game progression (shown as currency) Hiring HR staff and buying upgrades
Reputation Research yields reputation Unlocking and advancing research content

Building Data per Second with HR and Upgrades

The HR panel lists workers, each with a name, a hired count, a description, a production rate ("Produce X data per second"), and a cost in currency. Hiring more of a worker raises your passive data income; the cost is shown next to each entry.

The Upgrades panel lists upgrades with a name, description, effect, and cost in currency. Upgrades modify your production rather than adding raw output, so check the stated effect before buying.

A practical order of operations:

  • Buy the cheapest worker that meaningfully raises data per second.
  • When an upgrade's effect multiplies or improves what you already produce, it is usually worth more than another low-tier worker.
  • Keep some funding in reserve so you can respond when a new upgrade appears.

Using Research to Gain Reputation

Research entries appear as ????? until unlocked, then show a name, level, and description. Each research item states its reputation yield ("Research yields X reputation") and its data cost. Spending data on research converts it into reputation, which in turn opens up further content. Because research costs data, avoid draining your data balance entirely—keep enough flowing to sustain worker and upgrade purchases.

Saving, Orientation, and Other Practical Notes

  • Save often. The interface shows a "Saved: [time]" indicator and a "Save now" button, plus a "Restart" option. Use Save now before closing the tab.
  • Play in landscape. The game states it runs best in landscape mode and that on mobile you can only play in landscape orientation.
  • Performance depends on hardware. The event display may rely heavily on your hardware, so a slower machine may feel less smooth.
  • Report bugs via GitHub. The pre-release notice asks players to report issues through GitHub issues.
  • Track progress through the Achievements panel (with a progress count) and the Statistics panel (clicks, data spent/collected, money spent/gathered).

A Quick Example Session

Suppose you open the game fresh: click the detector repeatedly until you can afford your first worker. Hire it, then keep clicking while its passive output accumulates. Once funding allows, buy a low-cost upgrade whose effect boosts existing production. When your data balance is comfortable, fund a research item to gain reputation and reveal the next ????? entry. Save, then repeat—each cycle should raise your data per second and your reputation total.

The game is free to play in the browser and its source code is available on GitHub under an MIT license; contact is available via the project's GitHub or the [email protected] email listed on the About page.
