Context

Our client requested an automation solution for online blackjack games in few online casinos. The primary objective was to implement a perfect strategy, enabling the bot to play with a predefined balance ensuring no mistakes was made. The bot needed to be fast, stable, and user-friendly, providing an efficient and seamless gaming experience.

The automation of online casino platforms using Python has gained significant traction in recent years due to advancements in web scraping, artificial intelligence, and automated decision-making systems. With the increasing popularity of online gambling, operators and developers seek to enhance user experience, optimize game mechanics, and ensure regulatory compliance through automation techniques.

The customer had a well described retirements and we choose a Python + Playwright for this typo of automation, ensuring stability and scalability (in case of adding new platforms).

Online casino automation can be categorized into different domains, such as:

• Live Games: Online games such as Live BlackJack, when a game-stream presented to a user on a website and user can interact with dealer by clicking web-buttons on a screen and using chat. This type of games usually requires UI-Automation.
• Static Games: Online games, without any live dealer on a screen, but a program automatically shuffles and provides player with cards every new round. This type of automation usually requires API Automation.
• Real Games: Offline games, when player comes to real place and playing offline games. We will not describe this type of a play in this article.

In this case study we will show first two types of automation and share best practices with you.

Perfect Strategy requirement

The main requirement was the bot to play perfectly without mistakes, so the player RTP (Return To Player) will be close to 99-100%. So what is a perfect strategy in a blackjack?

The Repflect Strategy or Perfect Strategy in blackjack is an advanced card-playing method that combines elements of traditional basic strategy with adaptive decision-making based on observed gameplay patterns. Unlike rigid strategy charts, Repflect involves dynamically adjusting betting sizes, hit/stand decisions, and splits based on dealer tendencies, deck composition, and personal risk tolerance. It emphasizes pattern recognition, leveraging probability calculations alongside real-time game observations to optimize long-term winnings. While not a card-counting system, Repflect strategy integrates fundamental principles of expected value and statistical variance, making it a hybrid approach suited for experienced players seeking an edge in both casual and professional blackjack settings.

Discovery

We started a discovery phase with investigating different types of casinos and by checking possible ways of software automation. After a careful consideration and discussion with the customer we stopped on a list of games that were possible to automate.

List included UI and API only games to automate, after our alignment with the customer - InnovateWire team started implementation of the solution

Many online games had the same game provider which makes automation across different sites easier, by using the same program modules. On the other side some of the websites have custom software requires to make more custom automation.

Some of the websites does not provide any documentation regarding it's logic, so reverse engineering was used by leveraging DevTools and similar API's. This allowed to automate most of the bot logic in stable way, after spending some time on investigation and research.

Technologies & tools 

Python and PlayWright were chosen as the best tools in this particular scenario by InnovateWire team. We discussed these tools in our recent blog post here. This task required a framework to be developed, so the solution could be scalable, assuring reusage of the existing locit to any other website. As an example Inject-Framework could be taken, with the very similar functionality.

Solution included UI automation with PlayWright by using existing user session, assuring stability during gameplay and protection of unexpected log-outs. API automation was used on some games when it was possible. Most of the games were to complicated to be automated with API, so UI automation was implemented.
