Book of Olympus is a game from Apparat Gaming, built around an ancient and fantasy theme. It runs on a 5-reel grid running 20 paylines with a medium high-variance maths model, and a published RTP of 96.1%.
The mechanics are what make Book of Olympus interesting. Look out for scatter symbols that unlock free spins and extra bonus rounds. Its medium high variance balances steady wins with the odd larger payout. On balance, Book of Olympus is a dependable option worth a few spins in the demo first.
The RTP of 96.1% 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.
Book of Olympus 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.
