At 95.71%, 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.

About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
Secret of the Stones 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.
