How to Cheat in Cookie Clicker: Codes, Safe Limits and What Actually Breaks

Once you have the developer console open, the real question is which cheat code to run and how far you can push it before the game breaks. This guide covers every working cheat code organized by goal, explains the safe number ceiling, and tells you exactly which commands corrupt your save.

Why Cheats Work in Cookie Clicker: The JavaScript Reason

Cookie Clicker is built entirely in JavaScript and runs inside your browser tab. Every value in the game, including your cookie count, cookies per second, upgrade states, and sugar lumps, is a live JavaScript variable stored in your current browser session.

Your browser’s developer console has direct read and write access to those variables. When you type Game.cookies += 1000000000; you are not injecting anything foreign. You are using the same interface the developer used to build and test the game.

Orteil, the original developer, confirmed this by building Open Sesame into the game itself. The debug panel exists because the game was designed to be inspectable. That is why no third-party software is needed and why cheats carry no virus or malware risk when used on the official site at orteil.dashnet.org.

For how to open the console or activate Open Sesame, see the full Cookie Clicker hack guide.

How to Get Cheats in Cookie Clicker: Choosing the Right Method First

Before running any command, pick your approach based on how much control you want.

Approach	Best For	Access Needed
Single console command	One specific boost	Browser console open
Open Sesame panel	Point-and-click, no typing	saysopensesame in bakery name
Autoclicker script	Passive clicking without full cheating	Browser console open
Game.RuinTheFun(1)	Everything at once, no going back	Browser console open

Every method triggers the Shadow Achievement “Cheated cookies taste awful” except the autoclicker script and the cookie duplication command covered below. Export your save through Options before running anything. One wrong command has no undo.

Cookie Clicker Cheat Codes Organized by Goal

Most guides dump every command in one unordered list. This section groups them by what you actually want so you can copy exactly what you need.

Add cookies and set production rate:

Game.cookies += 1000000000;

// adds 1 billion cookies to your balance

Game.cookiesEarned += 1000000000;

// adds to your all-time baked total

// required to unlock certain milestone achievements

Game.cookiesPs = 100000;

// sets cookies per second to 100,000

Game.computedMouseCps = 5000;

// sets the value of each manual click to 5,000 cookies

Adding to Game.cookiesEarned matters. Many achievements and prestige thresholds check your lifetime baked count, not your current balance. If you only add to Game.cookies those milestones will not trigger.

Unlock upgrades and achievements selectively:

Game.SetAllUpgrade(1);

// unlocks every upgrade in the game without touching achievements

Game.SetAllAchievs(1);

// unlocks all achievements including shadow achievements

Game.Win(‘Neverclick’);

// unlocks one specific achievement by exact name

// replace Neverclick with any achievement name

Unlock everything in one command:

Game.RuinTheFun(1);

// grants every upgrade, every achievement, and 1 nonillion cookies

// this is irreversible during the current session

// do not use this if you plan to continue a legitimate run afterward

Sugar lumps, Krumblor and Santa:

Game.gainLumps(10);

// adds 10 sugar lumps to your total

Game.dragonLevel = 10;

// sets Krumblor the dragon to level 10

Game.santaLevel = 14;

// maxes out all Santa upgrades instantly

Save and session management:

Game.loadSave();

// reloads your save so recent changes register correctly

// run this after any command that changes a stat

Game.WriteSave();

// force-saves the current game state to your browser storage

How to Activate Cheats in Cookie Clicker Without Touching Achievements

Two cheat methods leave your achievement record clean. Every other method triggers “Cheated cookies taste awful” the moment the console or Open Sesame panel opens.

Method 1: Cookie duplication command

Game.cookiesEarned += Game.cookies;

Game.cookies *= 2;

This doubles your current cookie balance and adds the same amount to your lifetime total. It bypasses the detection condition in the game’s code that normally triggers the shadow achievement when you add cookies directly. Run it multiple times to compound the effect.

Method 2: Autoclicker script

var autoClick = setInterval(function(){

  Game.ClickCookie();

}, 17);

This clicks the big cookie once every 17 milliseconds, which equals roughly 60 clicks per second. The game treats every click as a legitimate player action. No cheat flag is triggered and no shadow achievement is awarded.

To stop it, paste this into the console and press Enter:

clearInterval(autoClick);

The autoclicker is the least disruptive cheat available. It preserves upgrade costs, building prices, and the incremental feel of the game while removing the repetitive manual clicking.

How to Unlock Cheats in Cookie Clicker Safely: The Number Ceiling

This is the section every other guide skips. There is a hard mathematical ceiling above which Cookie Clicker’s cheat commands start corrupting your session rather than helping it.

The JavaScript safe integer limit is 9,007,199,254,740,991 (roughly 9 quadrillion).

Cookie Clicker performs cost calculations using JavaScript’s standard number format. When you enter a value above the safe integer ceiling, JavaScript cannot represent it precisely. The game receives a rounded or incorrect value. This produces three specific bugs.

Bug 1: The infinity glitch

Setting Game.cookies = Infinity; sounds like the ultimate cheat. In practice the game’s building cost formula cannot process infinity as an input. Buildings display a price of Infinity and become unpurchasable even though your balance reads infinite. Your cookie counter can also flatline at zero after extended play with infinity active.

Use a large finite number instead. The recommended ceiling is:

Game.cookies += 1e15;

// adds 1 quadrillion cookies, well within the safe integer range

// this is enough to buy every building and upgrade multiple times

Bug 2: The negative cookie glitch

Entering a number beyond the safe integer limit causes JavaScript to return a small or negative number instead of the figure you typed. Your cookie balance drops dramatically. This is recoverable if you have an exported save but not otherwise.

Bug 3: The ascension inheritance break

Running Game.RuinTheFun(1); and then ascending through Prestige can break upgrade inheritance. Some upgrades that should carry through ascension do not transfer correctly when acquired through debug commands. If you plan to ascend legitimately, use targeted commands to boost specific values rather than unlocking everything at once.

Safe number reference:

Amount	Command	Safe?
1 billion	Game.cookies += 1e9;	Yes
1 trillion	Game.cookies += 1e12;	Yes
1 quadrillion	Game.cookies += 1e15;	Yes, recommended ceiling
1 quintillion	Game.cookies += 1e18;	Borderline, may cause display issues
Infinity	Game.cookies = Infinity;	No, breaks building costs

How to Remove the Cheated Cookies Achievement

Opening any cheat method automatically awards the Shadow Achievement “Cheated cookies taste awful.” It does not block other achievements or affect gameplay. It is purely cosmetic. Two methods remove it.

Console command:

Game.Achievements[“Cheated cookies taste awful”].won = 0;

Run this after using any cheat. The achievement disappears from your stats page immediately.

Neuromancy debug upgrade:

Inside the Open Sesame panel, enable the Neuromancy upgrade. This unlocks the ability to toggle any achievement on or off directly from the Stats menu under Upgrades. Click the achievement name to remove it.

The underlying save file still contains a cheat flag after either removal method. The cosmetic record is clean but the internal tag remains.

Frequently Asked Questions

Conclusion

Cookie Clicker cheats work because the game runs in JavaScript and your browser console has direct access to every game variable. Use the duplication command or autoclicker script to cheat without triggering the shadow achievement. Stay below 1 quadrillion per command to avoid the infinity bug and negative cookie glitch. Avoid Game.RuinTheFun(1); if you plan to ascend legitimately later. Export your save before running any command.
