The quantity of software providers for online casinos grows each month. However, not all software developers are considered as good as others. They all offer slot games of different genres and themes, but only several of them are considered the top software developers for quality casinos online. When forming these ratings we took into account portfolios, user reviews, as well as a variety of bonuses and options available in their games.
Quality criteria of the provider
The reliability of the provider is considered according to several criteria. One of them is the presence of certificates of independent laboratories and their licences like the Gibraltar gambling license, Curacao or MGA.
If a developer is approved by organisations such as eCOGRA, this indicates that it produces software with a proven random number generator. Meaning that any games it releases meet the required standards.
Another indicator of quality is a license from the regulator. You can get such a permit only after comprehensive testing of the games available. This is quite a complicated process. If a developer is in the business of getting approval for their slots, it means that they are aiming for a long run of high industry standards.
There are several other indicators of quality:
- Regular new releases;
- Availability of unique features and mechanics;
- Original bonuses;
- Quality graphics and design;
- A rich selection of genres and themes.
The top-level brands that meet all the above criteria often participate in exhibitions, receive special awards and sign partnership agreements with other studios and operators.
