Online Casino Software

Updated: 29.05.2025

The growth and evolution of gambling software have occurred with the rise of the Internet in common use. Naturally, among the most beloved features of the Web during its early stage were games including shooter and strategy games. During the early 90s, the creation of online gambling games was happening, and it is often said that 1994 marked the first launch of a true online casino. In time, Internet casino software has advanced to become more sophisticated, appealing, and user-friendly. As a result, developers today offer software for platforms that include a wide spectrum of opportunities. Furthermore, there is software for downloadable games, browser-based instant play games, Macs, mobile devices, and WebTV available to you.

Types of Online Casino Software Providers

The huge expansion of the online casino market has brought all types of software developers into the marketplace. It can be difficult to compare because they offer such different products. Some concentrate only on producing casino games, while others offer full service solutions for casino operators, including design, management, marketing and all back end processing. There are also niche developers who focus on producing only one type of game such as slots or bingo. Or they may specialize in a certain style, for example super realistic looking 3D games.

Reliability of Online Casino Software

When you are going to be dealing with large financial transactions in the anonymous atmosphere of the Internet, it’s vital to deal with a reliable company. A number of the software providers on today’s market have a checkered past; some have overcome their shaky start while others are still ironing out their problems. However, there are plenty of casino software developers which have built up a well deserved solid reputation. It’s best to look for licensing in a respected jurisdiction and certification that the software and algorithms have been verified by a third party testing organization such as TST. Membership in an industry self regulatory body like eCOGRA is another sign of reliability. All interactions between player and casino should be protected by 128 bit encryption technology.

Choosing an Online Casino Developer

When you choose an online casino, the gaming software it uses makes a huge difference. Think about what types of casino games you prefer. If you eat, sleep and breathe poker, for instance, then a casino that offers every known poker variant will be great fun for you. On the other hand, you may be a comics fan who loves casino games starring your favorite superheroes. There are casinos that have just what you are looking for, if their software provider has a licensing agreement with the comics brand. Or you may want to spread your play around among a large assortment of games. In that case, a casino with a huge portfolio of assorted titles will be just right. For some “hands on” examples, take a look at our software reviews and sample of casinos.
