The listed providers and their verified data
This page lists the slot machine providers present in our database. For each provider, you will find the number of listed games, the average RTP of their catalogue and a link to the full list of their titles. The ranking is by descending number of games, without any commercial promotion.
Only providers whose RTP data is certified by an independent laboratory (eCOGRA, iTech Labs, GLI) or available in official technical documentation are included. No commercial agreement with these providers influences the content of this site.
What is a slot machine provider?
A provider (or supplier) is the company that develops and commercialises slot machines. It designs the game, defines the RTP, volatility and bonus mechanic, then distributes the game to online casino operators under licence. The providers listed here are among the most active on the European market.
Which providers are listed on this site?
We currently list Play'n GO, Pragmatic Play, Nolimit City and Push Gaming, providers whose RTPs are certified by independent laboratories and available in their public documentation. Other providers are added as their official data becomes available.
Where is game data verified?
Data (RTP, volatility, maximum win) comes from technical sheets published by the providers themselves or certification reports issued by eCOGRA, iTech Labs or GLI. We do not estimate any value: if a piece of data is not documented in a primary source, it is not displayed.
