How to Evaluate Gambling Software Providers

There are a few things you should look out for when evaluating casino gaming software developers, as companies can look fantastic on the surface but may only offer a paltry few games.

The reverse can also be true where a company could offer hundreds of poor-quality titles. Follow the short list below to make sure you’re on the right track.

The best casino software developers have:

• A great variety of games of excellent quality, including game categories and themes.
• These games should have high RTP rates and be audited for fairness by a third party company.
• The games should be mobile-optimised for playing on the go from your preferred device.

Variety & Quality of Games

In order for software providers to appeal to online casinos, and indeed their players, they must offer a wide range of games. A developer that makes regular slots as well as jackpots and table games is far more valuable to casino than one that only creates slots.

This doesn’t mean that a developer can’t create only slots, but that if they choose to, they had better be of great quality and as varied as possible in order for them to be worth paying for from the perspective of a casino site.

Bonus features are another useful way to make a title stand out from the crowd and while stacked wilds are a nice touch, a true bonus game-within-a-game is the best option to hold player interest.

A good example of this is Play’n GO’s Rage to Riches slot. This features an interactive bonus game that is easily triggered, in which players act as a monster smashing down buildings. Small rewards like this really elevate the overall player experience.

Some developers create game themes based on characters that feature in multiple slot games, or that make guest appearances in other games, which creates a sort of universe within that software provider’s library.

A good example of this is ELK Studios, whose characters can often be seen popping up in each other’s games. Other developers have secured licences to valuable intellectual property to create slot themes based on tv shows, films and other pop culture phenomena.

More recently, several slot developers have gone beyond the usual role of creating games and invented tools that help casinos, players and developers alike. For example, Yggdrasil’s BRAG tool allows players to share big wins with friends on social media platforms.

Also, Quickspin Promote offers casinos the chance to customise games and offer players tournaments and races against others, creating a more interactive gaming feel that promotes player loyalty.

RTPs, Fairness and Security

RTPs, or return to player rates, are very important when it comes to choosing a game developer or title. The return rate is how much of a player’s bet they can expect to receive back from a game after a certain length of time, this will always be under 100%. For example, if a player chooses a game with an RTP of 96%, and bets £100 over 100 spins, they can fairly expect to end up with £96. It is the developer that decides this number and it is up to them to ensure it, though third-party auditors are required to check the accuracy and fairness of these rates under the laws of the United Kingdom Gambling Commission.

A transparent company is a safe company with regards to auditing. Developers that proudly display the results of these tests and the RTP rates of each game clearly make it easy for players to see that they have been checked for fairness and can be trusted. Sadly, this is not always the case and some companies make it almost impossible to find out the slot games with the highest RTPs, let alone the results of fairness checks.

If it is difficult to find out the RTP of a game, then it is probably one you should avoid. There are more than enough alternative slot games and developers out there that do display this information which make it unnecessary for you to play at any sites that are not forthcoming.

Mobile & Tablet Compatibility

Mobile gaming has become big business in recent years. With more players picking up mobile devices than sitting down at desktops, most developers are now turning their attention to mobile-first strategies to ensure their output can be enjoyed on as many devices as possible. In fact, development of mobile compatible games is now one of the fastest growing areas of the entire online gambling industry.

This rapid growth is thanks, in large part, to the development of new technology like HTML5. This computing language allows for smooth streaming of video and games within mobile web browsers. This has provided a major breakthrough for developers and online casinos alike, as players can now enjoy products on a mobile device without having to sacrifice valuable memory in downloading an app.

Though online casino games can still be played through dedicated mobile apps, the advent of HTML5 and its incorporation into the development of online games means that the titles themselves can reach a broader audience. Additionally, it’s easier than ever before for players to enjoy an immersive casino experience no matter where they happen to be, while developers can experiment with adding more special features to their products. Truly, it’s a win-win situation for both the game developers and the fans of their output.

How Does Online Casino Software Work?

Naturally, there are differences between the games you play in a land-based casino and those you play in an online casino. Though, to a player many of the rules and gameplay are basically the same, online games by necessity have to operate differently to their land-based counterparts.

To fully understand the work done by game developers, it’s wise to be aware of these differences and to understand how online casino software works. To give the best possible overview, let’s take a look back at the origins of online gambling software.

With the digital boom of the 1990s, developers like Microgaming, Playtech and NetEnt caught onto the new possibilities offered by the internet and started their own online casinos. Due to bandwidth limitations at the time, a lot of digital casino software was regularly downloaded onto desktops by players.

Some casinos still give that option to players, but it’s far less common platform now than it was 20 years ago. As internet speeds and technology improved, so too did online games. In recent years the industry has witnessed many breakthroughs in quick succession, leading to a climate of constant innovation and creativity in online gaming.

One of the biggest breakthroughs in recent years has been the advent of HTML5. This programming language has allowed for online casino games to be played on any device’s browser, whether desktop or mobile.

Improved AI and graphics have allowed developers to create incredibly realistic and immersive gaming experiences, replete with computer rendered croupiers such as in Yggdrasil’s Sonya Blackjack.

Betsoft and Realistic Games, in particular, have been exploiting the possibilities of high definition 3D graphics in crafting their casino products. Perhaps one of the most impressive examples of this is the rise of virtual reality gaming, which is being heavily explored by developers like NetEnt and Pragmatic Play.
