                              What are Actually Slot Providers and Online Casino Software Developers?

                              1. To begin with, casino games developers are companies that are in charge of creating casino and slot games. In other words, online casino game developers come up with the game theme, graphics, design, gameplay, audio and all similar stuff.
                              1. Once they come up with all these ideas, i.e. how everything should look, sound, and function, their next goal is to put all this into practice. They hire slot game developers who write codes in order for games to work. One of the necessary processes here is testing.
                              1. A game can be released after it has gone through various tests. Each brand’s main goal is to develop the best online casino software. After developing games, casino slot providers supply slot gaming companies with games.
                              1. Their goal is to distribute a variety of games that casino games companies ask for. There are many online gambling platform providers as well as developers, such as different online casino software solutions that develop and supply lots of different online casino sites.

                              Online Casino Software Providers Licencing

                              Any company or person who makes slot machines should possess a proper licence. Depending on the country or region one company is based in, there may be different operating licences.

                              In general, the best online casino providers should have a proper and legit gaming and operating licence. That said, this review focuses on top slot providers with the aforementioned licence type only. We can mention Relax Gaming, Playtech, Evolution Gaming, RTG, and many more.

                              How We Rate and Review Slot Game Providers

                              This is one of the casino software reviews that pays attention to many bits and pieces when determining the right slot games for you. Some of the key aspects we take into account include safety and licensing, number and type of games, design, gameplay, wagering style, users’ ratings, etc.

                              Safety and Licencing

                              Safety and Licencing


                              It goes without saying that one of the most important factors contributing to a good casino gaming experience relates to safety and security. Most of the time, casino game providers that hold a proper gaming licence are also the ones that are well-protected.

                              Number and Type of Games

                              Number and Type of Games


                              Of course, the number of different games a slot provider is ready to launch is what we consider, too. Not only that, but we also focus on different themes of the games supplied by operators. The more diverse the selection is, the more fun and entertaining players’ experience will be.

                              Design, Gameplay & Wagering Style

                              Design, Gameplay & Wagering Style


                              Providing games with a high-quality design is important for customers because this can largely expand their gaming experience. Similarly, the gameplay may be different for some casino game categories, and users can choose the ones with gameplay that fits them most.

                              Casino games also differ according to their wagering style. As not everyone likes every wagering style, we aim to describe different ways the wagering process can be done so that players can get to know them and choose the most suitable slot payment method for them. 

                              Users’ Ratings

                              Users’ Ratings


                              Your opinion matters to us. Therefore, we always look for users’ ratings of slots providers. We pay attention to their comments regarding the most important casino slot provider elements and compare them to our own reviews and tests, after which we come up with our own ratings.

                              Slot Providers Mobile Compatibility

                              As many of you prefer using mobile devices to desktop or laptop computers, there are slot providers whose goal is to make your mobile betting experience as best as possible.

                              They usually do this by trying to make their games have a responsive design. This means that games can easily adapt to different screen sizes and resolutions. Also, it is always important for mobile casino game providers to create mobile games without any bugs that run smoothly and fast.

                              Among many, some of the most popular casino mobile game providers are Pragmatic Play, Play’n Go, Booongo, and more.
