I haven't tried BetFury but I just had a look. They have quite a long list of slot providers. A total of 28 to be precise. I see a lot of well-known brands, but also a few I don't' really know, like Revolver Gaming or Fugaso. What providers are you missing and think should be there?

A casino is not all about Slots. RTP wise, those are the games with the biggest House Edge. If you want bigger chances to land some wins, try card or table games like Blackjack, Roulette, or Dice.
