Hellcatraz bonus buy: 83.69% of buys returned less than they cost
Model basis: feature-round returns are modelled as a calibrated heavy-tailed (capped log-normal) distribution, mean set to 96.88% (published buy RTP), tail scaled to the 51,840x ceiling. Providers do not publish feature-round distributions, so this is a model, not observed data, flagged per our methodology.

The honest read
A bonus buy is a single high-variance bet. The average is not the typical outcome: most buys here returned less than they cost, and the rare big multipliers that lift the average are exactly that, rare. Buying the feature does not improve your odds, it pays to skip to them. 18+, this is analysis, not betting advice.
