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.
