At 95.65%, the RTP is slightly below the industry average of ~96%. While this is typical for many popular slots, players should be aware of the slightly lower theoretical return.
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.
