The Technology Behind Casino Apps Explored


Behind every casino app is a suite of technologies working together to keep it running smoothly. Although it may not seem like a big deal to most users, the tech a casino uses to support its app can make or break its existence on the market. It also helps sites such as recommend various mobile casino apps to browse and review casinos to determine which are worth a player’s time.

To truly understand how casino apps work behind the scenes, let’s explore which kinds of technology are involved in bringing your favorite casino games to your fingertips.

How Do Casinos Decide Which Technology To Use In Their Apps?

When a casino creates a dedicated mobile app, the technology used depends on the kind of experience the casino wants players to have. A stellar user experience is always the ultimate goal, but you first need various technologies to work together before that can happen.

That’s where things get tricky because casino operators need to balance security, fairness, and ease of use. An overzealous security protocol could deter malicious third parties from harvesting players’ information, but this can also make logging in difficult for a user. An unstable server could make the games unavailable to players at random times, eventually discouraging them from playing again if it happens frequently.

Here are some of the technologies that casino apps use to keep players happy:

Server Infrastructure

A mobile casino app can’t expect to achieve anything without proper server infrastructure. It’s the backbone of the entire operation. If the server can’t handle the load, everything collapses.

The ideal server should be able to handle a large number of users simultaneously, such as during a busy weekend or at the launch of a new game. Specifically, the server must be able to handle multiple login attempts simultaneously, fulfill game requests, run numerous live streams for live dealer games, and handle transactions securely without slowing down or crashing.

Server Security

Server security also goes hand in hand with stability when maintaining a mobile casino app. Because casinos deal with sensitive information all the time, a good server needs to have a secure firewall, strong encryption and state-of-the-art intrusion detection systems. The server must also be easy to update, with little to no downtime, to stay ahead of newly developed hacker attacks.

Random Number Generators

Casino games depend heavily on random number generators (RNGs), so an online casino operator must use a fair and independent RNG for its games. RNG tech is so important that various gaming commissions check periodically to ensure games are genuinely random and don’t favor any particular player – or the operator.


The primary function of an RNG is to guarantee that games are unpredictable, especially in an online setting where players can’t physically see what’s happening. A well-coded and officially vetted RNG assures the player that the operator isn’t manipulating results in their favor. It also helps make online casino games just as fun and thrilling as their physical counterparts.

Game Providers

You may have seen names such as Pragmatic Play and NetEnt mentioned in online casino reviews. They may sound like just another company name to most people, but they actually contribute more than you’d expect behind the scenes.

Game software providers are the minds behind the massive library of games you’ll find in every online casino. Through software development, game providers deliver a variety of slot games, table games, and live dealer games to casino operators. Without agreements between the providers and the operators, players wouldn’t have anything to play.

Payment Processors

Online casinos are fun, but if you encounter a payment-related problem, it can be very frustrating. Whether the problem is with deposits or withdrawals, the experience can quickly turn sour.

This is why online casino operators have to make sure they’re working with as many reputable payment processors as possible to ensure player satisfaction. By doing so, not only do they provide several options for players, but they also deliver peace of mind. Players know their funds are secure when they can comfortably use their preferred payment method.

Mobile Optimization

A secure server and a library of fair (but fun!) games are useless if the app can’t run on an older phone.

Not everyone upgrades to the newest phone every year, so online casinos must make sure their apps are compatible with older devices. The point of an online casino is to make the games accessible wherever the player is; they can’t achieve this if their app only works with the newest phones. Online casinos can do this by creating a responsive design on their website (for browser-based casinos) or by developing a dedicated app that can run on older phones.

Responsive website designs should automatically adjust the page’s size and layout depending on your device, which helps immensely with load times. On the other hand, dedicated mobile apps can be made so that they don’t require much processing power from the device to run, regardless of the phone’s age.

Data Analytics

Online casino operators have hundreds (or thousands!) of games in their library, and a casual player can’t discover all of the games themselves. This is when data analytics can help.


Through personalized algorithms, online casino operators can help players find similar games they might enjoy by analyzing their behavior and preferences. For example, if a player prefers ocean-themed games, the algorithm can pick up on this pattern and suggest similar games for the player to try. Or, if a player likes to play conservatively, the algorithm can point the player towards games with lower minimums.

Customer Support Infrastructure

Things don’t always go as planned, so it’s important for a player to have someone to ask for help online. An online casino app needs a responsive and easy-to-find help section so players won’t spend too much time trying to find a solution.

Most online casinos try to offer several customer support options, the most common being live chat service and email assistance. The fewer hoops a player has to go through when seeking assistance, the better their experience will be.
