The RTP of 96.17% is right around the industry average of ~96%. This represents a fair return that's in line with what most modern slots offer.

About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
Dr. Acula features scatter symbols that can trigger free spins rounds. Landing the required number of scatter symbols anywhere on the reels activates the free spins feature, giving you extra chances to win without additional bets. During free spins, special modifiers may apply to boost your winning potential.
