The RTP of 96.26% is right around the industry average of ~96%. This represents a fair return that's in line with what most modern slots offer.
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.
40 King features scatter symbols that can trigger free spins rounds.

During free spins, special modifiers may apply to boost your winning potential.
