How to judge any studio
- Independent testing. Reputable studios certify their RNG and RTP with labs like eCOGRA or GLI.
- RTP transparency. The best publish the RTP (and flag multi-RTP versions). Always check the figure on the specific game.
- Consistent maths. A studio’s volatility profile is usually a reliable signal of how its games feel.

Frequently asked questions
What should I look for when choosing a slot game provider?
Consider the studio's reputation for fair, independently tested maths, its typical volatility range, and how polished its mobile builds are. Established providers such as Pragmatic Play, NetEnt, and Play'n GO publish RTP figures for each title, which SlotWhizz lists on every game page so you can compare before you play.
Does the slot studio affect my chances of winning?
The studio determines the game's maths model — its RTP, volatility, and hit frequency — which shape your experience over time. No studio can guarantee wins, and the house edge is always present. What differs is how often wins land and how large they tend to be, so matching a studio's style to your preference matters.
How many slot providers can I browse on SlotWhizz?
SlotWhizz catalogues over 560 developers, from globally recognised studios like NetEnt and Big Time Gaming to smaller independent teams. You can filter by provider on the providers directory page, making it straightforward to find every game from a particular studio in one place without searching across multiple casino sites.
What is the Megaways mechanic and which studio created it?
Megaways is a reel engine invented by Big Time Gaming that varies the number of symbols on each reel with every spin, creating thousands of potential ways to win per round. BTG licenses the engine to other studios, so you will find Megaways games from a wide range of providers, each with their own theme and maths.
