Which slot studios actually run the highest return-to-player rates? This ranks 73 providers by the average provider-verified RTP of their games in Slottomat’s first-party database (sourced from official provider data via the SlotsLaunch feed, not estimated). Across 4,267 verified games from 339 studios, the average verified RTP is 95.62%.
Providers are ranked by the mean of the provider-stated theoretical RTP across their verified demos (minimum 15 games with a confirmed RTP, so single high-RTP titles don’t skew the ranking). RTP describes long-run design, not any session, and every game is a free demo. Method: How We Verify Game Facts · single-game ranking: High RTP Slots · full data: RTP Database.
Slot providers ranked by average verified RTP
All figures are provider-stated theoretical RTP for demos indexed on Slottomat, refreshed from our first-party database. A higher studio average means more of that provider’s catalogue is built with above-baseline return rates — useful when choosing which studios’ demos to try first.
