Expert’s Opinion

363 Articles

NetEnt’s Secret of the Stones masterfully blends atmospheric design with engaging gameplay. One of its biggest strengths is the pick-and-click Free Spins feature, which not only personalizes the bonus round but also adds a layer of anticipation as players uncover multipliers, wilds, or additional spins. The flexibility between the Classic and MAX versions caters to different player types — the former provides a more balanced experience, while the latter offers high-risk, high-reward potential with a staggering 25,000x maximum win. Visually, the slot impresses with its detailed rune-covered symbols and enchanting soundtrack, pulling you into a world of druidic magic. However, the lack of variety in the base game can make it feel repetitive during long sessions, as most excitement hinges on triggering the Free Spins. Despite that, Secret of the Stones continues to stand out as a memorable and rewarding slot for players who enjoy immersive themes and potent features.

Secret of the Stones Slot Gameplay and Mechanics

Secret of the Stones Slot BaseplayThis slot plays out on a traditional 5×3 grid with 25 fixed paylines, providing a familiar setup for both new and experienced players. To land wins, players need to align matching symbols from left to right across active paylines. The controls are intuitive and positioned beneath the reels, allowing players to adjust bet levels, activate autoplay, or spin manually. The game is smooth and responsive, thanks to its HTML5 framework, making transitions between gameplay and features seamless.

The standout mechanic is the Free Spins bonus, initiated when three or more scatter symbols land. This triggers a pick-and-click round where players choose from stone tablets to unlock bonus modifiers. These can include extra free spins, multipliers, or wild reels—making each bonus round feel unique. The game also includes wild symbols that substitute for regular symbols to help form winning combinations, adding excitement even outside the bonus rounds.

Secret of the Stones Slot RTP

96-97 RTP Range“Secret of the Stones” offers a solid RTP of 96.72% in its Classic version and a slightly higher 96.81% in the MAX version. This figure indicates the theoretical percentage of wagered money that players can expect to receive back over time. These RTP values position the slot as a fair and rewarding choice compared to industry averages. The Classic version appeals to players looking for balanced risk and reward, while the MAX version increases volatility for those chasing large payouts.

The consistent RTP ensures long-term value while maintaining excitement in both base and bonus gameplays. NetEnt’s transparency and adherence to fairness standards are evident, and players can feel confident that they’re engaging with a mathematically sound and tested game. These figures make the slot particularly attractive to strategic players who factor RTP into their gameplay choices.

Secret of the Stones Slot Volatility

High volatility iconVolatility in “Secret of the Stones” varies based on which version you choose. The Classic version comes with medium volatility, offering a good balance between frequent smaller wins and the chance of triggering more significant bonuses. This makes it suitable for casual players or those with limited bankrolls who want longer playing sessions with moderate risk.

On the other hand, the MAX version is designed for high-volatility play, ideal for thrill-seekers. It features much larger win potential, up to 25,000x the stake, but with less frequent payouts. The shift in volatility means that players should choose based on their risk tolerance and gaming style. This dual setup gives the slot impressive replay value and flexibility, making it appealing to a wide player base.

Whether you're playing conservatively or going all in, the game’s broad bet structure ensures that you can tailor your experience to fit your bankroll and objectives.

Before the spins begin, players are taken to a pick-and-click screen featuring 20 stone tablets.
