How to Build a Script That Monitors Changes in No Deposit Bonus Offers on Casino Sites

If you frequently visit casino-related websites to find the latest no deposit bonus offers, you’ve probably wished there was a way to get notified automatically when something new is posted. Manually checking these pages can be repetitive — but as developers, we can automate it.

In this guide, we’ll build a Python script that monitors changes on a bonus listing page and alerts you when a new offer appears. For our example, we’ll use https://nodepositbonushungary.com/, a site that regularly publishes no deposit bonuses for Hungarian players.

What We'll Build

This script will:

Scrape the content of the page
Extract and store bonus-related data
Compare it to the previous version
Notify you if something new appears

It’s a great mini project if you're just starting with Python, scraping, or automation.

Tools and Libraries

You’ll need Python installed, along with the following libraries:

pip install requests beautifulsoup4 schedule

You can also add:

difflib – to compare text content
smtplib or python-telegram-bot – for notifications

Step 1: Fetch the Page Content
Use the requests and BeautifulSoup libraries to get and parse the HTML:

import requests
from bs4 import BeautifulSoup

url = 'https://nodepositbonushungary.com/'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')

Step 2: Extract Bonus Data

Let’s assume bonus offers are inside h3 tags. We’ll extract them as plain text:

bonuses = soup.find_all('h3')
bonus_list = [b.get_text(strip=True) for b in bonuses]

Step 3: Save Data Locally

We'll store the latest scraped data to a text file for future comparison.

with open('bonuses_latest.txt', 'w', encoding='utf-8') as f:
    for bonus in bonus_list:
        f.write(bonus + '\n')

Step 4: Compare With Previous Data

Now let's check if the content has changed compared to the last saved version.

def read_previous():
    try:
        with open('bonuses_old.txt', 'r', encoding='utf-8') as f:
            return f.read().splitlines()
    except FileNotFoundError:
        return []

old_data = read_previous()
new_data = bonus_list

added = set(new_data) - set(old_data)
removed = set(old_data) - set(new_data)

if added:
    print("New bonuses found:")
    for a in added:
        print("-", a)

with open('bonuses_old.txt', 'w', encoding='utf-8') as f:
    for bonus in new_data:
        f.write(bonus + '\n')

Step 5: Automate It

Let’s schedule this script to run every hour.

import schedule
import time

def job():
    print("Checking for bonus updates...")
    # Place the scraping and comparison logic here

schedule.every(1).hours.do(job)

while True:
    schedule.run_pending()
    time.sleep(1)
