The RTP of 96.09% is right around the industry average of ~96%. This represents a fair return that's in line with what most modern slots offer.
High volatility means longer gaps between wins, but when wins do land, they can be significantly larger. A bigger bankroll and patience are recommended for this type of slot.
About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
Hellish Seven 100 features scatter symbols that can trigger free spins rounds.
