The medium high volatility strikes a middle ground that should suit most playing styles. Overall it's a well-rounded slot game that knows what it is.
At 95.32%, 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.
Medium-high volatility means wins come less frequently but tend to be larger when they hit. Players should be prepared for dry spells between bigger wins, requiring a moderate bankroll.
About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
3.0 / 5 — Good
