Casino Software

By Dale Shelabarger, Updated:

While playing your favourite online pokie, have you ever wondered where it came from? Who made the casino software? How did it end up at your favourite casino? How come the same pokie can be found on numerous casino sites? The reason the same pokie game can appear on multiple online casinos, is because the casinos do not create the games themselves. They leave it to the experts – the software developers who design and develop the games, package them into platforms and sell licences to the casino operators.

Best Casino Software

Some casinos stick with one developer’s platform, throw a bit of branded jazz over it (“a skin”) and chuck it out. However, the best casinos tend to offer a comprehensive range of games that are also in keeping with the feel and the brand of their online platform.
When playing your favourite online pokies, it’s worth noting the developer, whose name will often appear as the game is loading. You may even begin to see a pattern developing. Once you’ve latched onto your favourite casino game developer, it’s going to be that much easier to keep track of its latest releases.

Casino Software - Regulatory Requirements and Testing

Trust and fair play are absolutely crucial for the success of online casino software. Thankfully, to ensure that players are protected there exist a variety of regulatory bodies which oversee the industry and which require all games to be thoroughly tested.

Online Casino Software Testing

One of the most important elements of testing relates to the evaluation of a game’s random number generator. The outcomes of all casino games are generated by RNGs. Therefore, to ensure fairness, these numbers must be unbiased, unpredictable and have an equal probability of being generated.

Then you’ve got the pay-out percentages (RTPs) which is what the player can expect to win when calculated over the wagering of 100 credits. This area is especially important given that gamers pay particularly close attention to RTPs when choosing an online casino game. As with testing, a game’s RTP must be officially ratified by an independent agency before it can be displayed online. For UK operators, eCOGRA undertakes these tests.
