The Technology Behind Online Casinos

Online casinos have been around since the mid-1990s and have only risen in popularity, with more seemingly being launched every other day. As the technology keeps improving, online casinos keep upping the ante and offering improved features and products.

Have you ever wondered how these casinos can offer such impressive game with top of the line graphics, animations and sounds, a wide range of bonuses, promotions and special features and top service such as banking, customer support and loyalty programs? Here we’ll take a look at the technology behind online casinos that makes them safe and secure, at the same time as being fun and entertaining.

Safe and Secure

A good place to start with any online casino is with its security. You will be registering with your personal information and banking with your financial information so you will want to know that it’s safe. Casinos use SSL data encryption technology which is the same technology used by banks to protect their customers’ financial information. A complex code that scrambles your financial and personal information makes this data almost impenetrable. If that weren’t enough, firewalls prevent the information that is stored on the casino’s hard drive servers from being accessed. Third party security professionals often handle the security of the casino, so you can rest assured that your information is in good, secure hands.

Random Number Generators

The thrill of playing lies in your chance of winning. Everyone loves pressing the spin button on a pokie machine and watching those reels turn, but what is actually going on behind the reels and how do you know if you have a fair chance of winning on every spin. That is where the random number generator (RNG) comes in. The RNG creates numbers at several hundred combinations each second and when you hit the spin button, the next number combination lets the machine know when the reels should stop spinning. Online casinos use third party auditors to make sure that these RNGs are completely random and fair.

Software Providers

Different online casinos are powered by different software providers. Some online casinos offer games from a range of different software providers. These companies develop the games and features that you will come across at the casino. They have their reputations at stake so they ensure a high quality service. Many of them are members of gambling councils that ensure they maintain a high standard and they are also tested by third party labs to ensure they offer fair play.

Live Casino Technology

More and more online casinos are now offering a live dealer games suite. These games use webcam technology to stream real live gaming to the player. Gaming tables are set up in studios with live dealers who deal cards or spin the roulette wheel in real time. Players can enjoy chatting with these dealers as they play. New live dealer games are being released all the time with the most common options including live blackjack, live roulette, live baccarat, live 3 card poker and live casino hold’em.


The technology behind online casinos allows them to become accessible to a wide range of players. The games can be developed in a range of different formats to suit different players. In the past, games were available either for download or for instant play via Flash technology, but today, it is more common to find casinos that offer instant play for all players so that players no longer need to download any games. In addition, mobile technology has offered a new type of casino play that is taking the online gambling world by storm. According to Juniper’s research, mobile betting on casinos and poker is expected to exceed $60 billion by 2018. The software also supports play in multiple languages and often offers support in multiple languages, making the casino accessible to players around the world.


Online casinos offer a range of deposit and withdrawal methods. Players can set up their casino account and choose their banking methods and their currency, offering flexibility for all customers. Most commonly, whether you play via the casino’s online or mobile platform, you will be able to use the same wallet for simplicity and convenience. These may be e-wallets that connect your casino account and bank account via a third party, they may be credit cards or debit cards or they may be a pre-paid card that does not require you to enter personal or financial information.


There is a lot of technology behind an online casino as there are many aspects to how an online casino runs. And, in fact, as technology advances, the technology changes. For example, with the growth of virtual reality technology and its popularity, online casinos are beginning to offer VR games. It is likely that technology for online casinos will continue to advance and evolve as customer’s preferences continue to change.
