Automating Cookie Clicker!

Prize: $5 Cookie Grant and 3 snowflakes :)

Hello! I am Aditya, and i'll teach you how to use Python and Selenium. Selenium is a browser automation tool used by engineers to test their applications, today we will be using it for a completely different purpose, automating cookie clicker.

Perquisites:

• An Editor(I recommend PyCharm for this)
• Python(I recommend 3.13)

Setup

Make a new folder for the project and make a virtual environment using

python3 -m venv .venv

to activate the virtual environment on macOS/penguinOS(Linux) run:

source .venv/bin/activate

on windows run:

.venv\Scripts\activate.bat

now you need to install the selenium package, which lets us use selenium with

pip install selenium

now make a main.py file, this file will contain the main code for the project

Writing the Code

Open up main.py and let's start by importing the necessary libraries:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time

Now, let's initialize the browser and open Cookie Clicker:

# Create a Chrome webdriver instance
driver = webdriver.Chrome()

# Open Cookie Clicker
driver.get("https://ozh.github.io/cookieclicker/")

# Wait for the page to load
time.sleep(10) # This is also time so you can click your language and it doesn't crash

The fun part: actually clicking cookies. Here's how to find and click the big cookie:

# Find the big cookie element
cookie = driver.find_element(By.ID, "bigCookie")

# Click it a bunch of times (adjust the number based on your patience)
for i in range(100):
    cookie.click()
    time.sleep(0.1)  # Don't be TOO cruel to your CPU

Want to make it smarter? Let's add automatic building purchases:

def buy_buildings(driver, how_many_times=5):
    """Automatically buy buildings because manual clicking buildings is for people
    who haven't discovered loops yet."""
    
    for _ in range(how_many_times):
        # Find all building purchase buttons
        buildings = driver.find_elements(By.CLASS_NAME, "product")
        
        # Click each building we can afford (from bottom to top, because we're fancy)
        for building in reversed(buildings):
            try:
                building.click()
            except:
                # If we can't afford it, just move on with our lives
                pass
        
        time.sleep(1)

# Call it
buy_buildings(driver, how_many_times=10)

Here's a complete script that clicks cookies and buys buildings forever (or until you get tired and stop it):

from selenium import webdriver
from selenium.webdriver.common.by import By
import time

driver = webdriver.Chrome()
driver.get("https://ozh.github.io/cookieclicker/")
time.sleep(10)

cookie = driver.find_element(By.ID, "bigCookie")

try:
    cycle = 0
    while True:  # Keep going forever
        cycle += 1
        
        # Click the cookie 50 times per cycle
        for _ in range(50):
            cookie.click()
            time.sleep(0.05)
        
        # Try to buy buildings
        buildings = driver.find_elements(By.CLASS_NAME, "product")
        for building in reversed(buildings):
            try:
                building.click()
            except:
                pass
        
        print(f"Cycle {cycle} complete. Your cookies are accumulating rapidly.")
        time.sleep(1)

except KeyboardInterrupt:
    print("\nBot stopped. Check your cookie count - it's probably ridiculous now.")
finally:
    driver.quit()

The key change: we replaced for cycle in range(50): with while True: so the bot keeps clicking forever.

What You've Learned

You now know:

• How to use Selenium to automate a web browser
• How to find and interact with elements on a webpage
• How to loop and conditionally perform actions
• How to waste a lot of computational resources for a silly game (a valuable life skill)

Next Steps

Want to make it even more automated? Try:

• Adding logic to detect and click golden cookies
• Tracking your cookie per second (CPS) and logging it
• Creating a GUI to start/stop the bot
• Realizing this is just the beginning and you're now a full-stack Cookie Clicker developer

Now go forth and let your bot achieve cookie dominance.
