Online Casino Software

An online casino allows a player to play his favorite casino games from home and use bonuses to make his game experience interesting. Graphics and animation, the interface, game range, promotions, payment methods, and customer support all contribute towards this experience. At the core of an online casino is the software that powers it.

The software powers the online casino, it is as simple as that. It takes care of the different aspects of online casino gambling, from the look and feel, the range of games, the features that the games come with, the random nature of the spin of a wheel or the dealing of a hand, the way the bonuses are tracked, the way the payment methods work, and much more.

In the early days, each casino was powered by one casino software provider. The emergence of new technology now makes it possible to have casinos that are powered by multiple software providers.

Kinds of Online Casino Software Providers

You find a large number of software providers today compared to the bare minimum numbers that were there in the early days of the online casino industry. Microgaming was a pioneer, having set up shop back in 1994, and is still considered an industry leader. There are a number of others as well.

Categorizing software providers is not the easiest of tasks because most of them provide the same range of games. One way of differentiating them is on the basis of the play mode they support. All the early casino software providers offered games in the download mode only. The arrival of Flash technology led to the emergence of the no download instant play mode,

These same providers now offered games in both these modes:

  • Download mode: You have to download the software to your computer to be able to launch the casino.
  • Instant play mode: You can play directly from a web browser in instant play mode. You don’t need to download software. However, until very recently the game range was lighter in this mode; you did not get the full complement of games.

The advancements in technology have now ensured that you get the full complement of games in both download and instant play modes. As a result, a number of casino software providers are now offering their games solely in the instant play mode. A classic example of this kind of provider is NetEnt, which is an industry leader.

Live dealer casinos recently emerged which feature real-life dealers with whom you can interact through live chat and video. Most of the top software providers offer live dealer casino games as well. However, the emergence of this game type has led to a new breed of specialist software providers – those who provide solely live dealer games. Good examples of such providers are Evolution Gaming and Extreme Live Gaming, among others.

There are other specialist providers in the overall casino gaming scene as well. For instance, Quickspin and Habanero are two providers that develop only slots. BetSoft Gaming is a specialist providers of cinematic quality 3D slots – the first to do so actually – though it does also have other games on its plate.

And to round off the categorization, one more area to look at is the mobile casino industry. All the major software providers now also offer mobile casino solutions to operators, but there are a few that are actually mobile first: their casino software is primarily for mobile casinos.

Casino Software Testing and Certification

Three of the biggest concerns for online casino fans right from the time the first online casino was launched have been safety, reliability, and security. That is not the only challenge: software providers need to deliver games that not only look great – adaptations of land-based casino games need to look as good as the original at least – and have great features but are also fair and reliable . This is where testing and certification of software becomes critical.

All software providers put their games and software through a comprehensive testing and audit process. This is done to ensure that the games are 100% in terms of throwing up random results and are therefore fair. Regular and rigorous auditing of the games ensures that the games consistently deliver on the payout percentages they promise while advertising them. To ensure complete fairness the testing and auditing of casino software is done by independent and neutral third party agencies.

Top casino software audit companies include:

  • iTech Labs
  • Technical Systems Testing (TST)
  • Gaming Labs International
  • NMi

These organizations put the software and games through stringent checks across multiple parameters. Some of the elements they test for are listed below:

  • 100% randomness in all game outcomes, be it the card hand dealt, balls rolled, dice thrown, or reels spun.
  • Accuracy in the Return to Player (RTP) values and payout percentages.
  • Preparedness of game logs and interruption protocols.

Once the testing is done the testing agency publishes a report for the casino highlighting the protocols followed and the outcomes arrived at. Successful testing allows the casino to display a certificate with the logo of the agency on its homepage, and clicking on the certification link displays the certificate.

Online Gambling Licensing Jurisdictions

One way that casino software providers establish their credentials as a respectable provider of games is by getting licensed and regulated by reputed licensing jurisdictions. Licensing is anyways required to be in compliance with the gambling legislations laid down.

Some of the popular licensing jurisdictions across the world include:

  • The United Kingdom (United Kingdom Gambling Commission)
  • Malta (Malta Gaming Authority)
  • Gibraltar (Government of Gibraltar and the Gibraltar Gambling Commissioner)
  • Kahnawake (Kahnawake Gaming Commission)
  • Curacao (eGaming Curacao and the Government of Curacao)
  • Alderney (Alderney Gambling Control Commission)
  • Antigua and Barbuda
  • Isle of Man
  • Cyprus
  • Costa Rica

Check whether the casino displays its licensing information and where it is licensed as this gives a guarantee of safety, reliability, and trust.
