Kinds of Online Casino Software Providers

There are many kinds of casino software providers. For instance, there are those that develop downloadable games, those that develop HTML5 instant play games, and those that develop both. Some even develop land-based casino games as well as virtual or online games.

Some casino game vendors develop all types of casino games where others focus mainly on one type of game, like slots or live dealer games. What all successful online casino providers have in common, however, is that their offerings are all designed to be fun, lucrative and easy to play.

Casino Software Testing and Certification

It’s one thing to produce an online casino game that looks virtually identical to its land casino counterpart, and another to ensure it delivers the exact same odds or random results, time after time, which is where independent testing, auditing and certification firms come in.

To prove to players and their licensing jurisdictions that a casino’s game results are 100% random and meet their advertised pay-out percentages (return to player), their games must undergo rigorous testing and auditing by respected 3rd-party companies.

One such company is iTech Labs, which ensures that casino games are compliant with the prescribed industry and software standards, and are resilient, reliable and most critically, fair. They test, among other things, that:

  • All dealt cards, thrown dice, rolled balls, spun wheels, spinning reels and so forth are 100% fair and random
  • That the return to player (RTP) calculation for each and every casino game type is correct
  • All games work correctly and that their logs and interruption protocols are fully operational

On completion of testing, a report will be issued highlighting the respective testing and auditing protocols used, and the results thereof. In the case of a successful evaluation, the testing firms allow the casino to put a certification logo on its homepage, along with a link to its respective certificate.

Online Gambling Licensing Jurisdictions

All leading online casino software is licensed and regulated by one or more online gambling licensing jurisdictions. The most popular and respected of these include but are not limited to the UK, Curacao, Costa Rica, Cyprus, Alderney, Kahnawake, Malta, Antigua and Barbuda, the Isle of Man and Gibraltar.

Whenever you see an online casino - and by extension its online casino software provider - that is licensed in any of the jurisdictions mentioned above, you can rest assured that it is comprehensively regulated and monitored regularly, and is thus safe, trustworthy, secure and reliable to play on.
