Endorphina plays it remarkably safe with their recent maths models. Their RTP sits in a stubbornly tight band just above 96%, which is a solid average today while other developers quietly slash theirs. But that reliability demands a steep trade-off. You take on highly volatile mechanics that rarely deliver the payouts to justify the risk.
Titles like 3 Golden Chests run high on volatility yet stop around 1400x. Even Gift of Midas only pushes to 6500x. You are giving up those massive top prizes. What you get instead is polished, predictable behaviour under the hood without having to dodge sneaky lower-paying configurations. The trade is stability over spectacle.
