Cookie Clicker Hacks: Three Backdoors the Developer Left Wide Open

Sometimes the most elegant software architecture is just finding the backdoor the developer forgot to close — or in this case, the one they intentionally left wide open.

Cookie Clicker is a deceptively simple idle game by developer Orteil: click the big cookie, earn cookies, spend cookies on buildings and upgrades, earn more cookies, repeat — forever. It sounds absurd, and it is. It’s also utterly addictive.

But here’s the twist: Cookie Clicker is a browser game written in JavaScript, and its internal state is exposed as global variables on the page. That means anyone with a browser console can reach right in and rewrite the rules.

Below are three hacks — from the nuclear option to the subtle — each a single line of JavaScript.

Opening the Browser Console

The Developer Console lets you run JavaScript directly on any page. To open it on the Cookie Clicker page:

Windows / Linux: Press F12 or Ctrl + Shift + I, then click the Console tab.
Direct shortcut: Ctrl + Shift + J jumps straight to the Console.

Mac: Press Cmd + Option + I, then click the Console tab.
Direct shortcut: Cmd + Option + J jumps straight to the Console.

You’ll see a blinking cursor. Type (or paste) any command and press Enter to run it. Commands are case-sensitive — type them exactly as shown. Seeing undefined after a command is completely normal.

📱 On a phone or tablet? Mobile browsers don't have DevTools — but each hack below includes a bookmarklet you can use instead. No computer needed!

Hack 1: “Ruin The Fun” — The Developer’s Own God Mode

This is the nuclear option. Orteil actually built a RuinTheFun() function directly into the game’s source code — a single call that instantly grants you nearly infinite cookies, every building, every upgrade, and every achievement simultaneously.

 js 
Game.RuinTheFun();

One line. The game is beaten.

How does it work?

Game.RuinTheFun() is a built-in convenience function Orteil left in the production code — originally used during development to test the late-game state without grinding. Because Game is a global variable, anyone with console access can call it.

Hack 2: The Invisible Auto-Clicker

If “Ruin The Fun” is too destructive and you actually want to watch the numbers go up, this is the classic approach. It silently sets up a background loop that clicks the big cookie 100 times a second — no menus, no buttons, no interruptions.

 js 
setInterval(function() { Game.ClickCookie(); }, 10);

The 10 is the interval in milliseconds — so this fires 100 times per second. You can raise it to 100 (10 clicks/sec) for a more leisurely pace, or drop it even lower for absolute insanity.

How does it work?

Game.ClickCookie() is the same function the game calls when you physically click the cookie. setInterval runs it on a timer in the background. The auto-clicker keeps running until you refresh the page, so you can switch tabs and come back to a mountain of cookies.

javascript:setInterval(function(){Game.ClickCookie();},10);void(0);

💡 Tip: The auto-clicker stacks with upgrades and buildings — so activate it after buying a few cursor upgrades for maximum effect.

Instead of building your own cheat menu, you can just force Cookie Clicker to reveal its own hidden developer tools panel. The game has a built-in easter egg: if your bakery name ends with saysopensesame, a small wrench icon appears in the top-left corner. Click it to access sliders and buttons for spawning Golden Cookies, manipulating time, and more.

 js 
Game.bakeryName = "Hacker saysopensesame";
Game.bakeryNameRefresh();

A wrench icon will appear in the top-left of the game. Click it to open the full dev panel.

How does it work?

Cookie Clicker checks the bakery name for the string saysopensesame and toggles visibility of the dev panel accordingly. Game.bakeryNameRefresh() re-evaluates the name immediately, so you don’t have to wait for the game to check on its own.

javascript:Game.bakeryName="Hacker saysopensesame";Game.bakeryNameRefresh();void(0);

Using Bookmarklets on Mobile

Mobile browsers don’t have a developer console — but they do support bookmarklets. A bookmarklet is a bookmark whose URL is JavaScript code. When you tap it, the browser runs the code on the current page.

Step 1: Create a New Bookmark

In your mobile browser, bookmark any page. The URL doesn’t matter — you’ll replace it next.

Step 2: Edit the Bookmark

Open your bookmark manager, find the bookmark you just saved, and tap Edit:

Change the name to something descriptive (e.g. Cookie Clicker God Mode)
Replace the entire URL with one of the bookmarklet codes from above (copy the whole thing — it must be one continuous line)

Save the bookmark.

Go to orteil.dashnet.org/cookieclicker and wait for the game to fully load.
Tap the address bar, type the bookmark name, and when it appears in the dropdown, tap it.

The script will inject and run instantly.

Want to write your own bookmarklets? The Bookmarklet Compiler turns any JavaScript snippet into a ready-to-use bookmarklet in seconds.

Enjoy your mountains of cookies — however you choose to earn them!
