Secret of the Stones Slot Machine

Secret of the Stones is a slot with a 5x3 playing field and 25 flexible paylines, offering a single free spins feature with a myriad of little modifiers that make it different each time you are lucky enough to see it activated. So come and learn the ancient teachings these old druids left behind!

While most people nowadays associate the word druid with fantasy novels or a video game class, they were a rather prominent feature in the Celtic regions of Europe before the Romans brought over Christianity which spelled out their doom. But worry not — druids aren't something you will only find in the latest Asterix and Obelix film, but also in this NetEnt release.

The user interface is something that most NetEnt fans will find quite familiar. It uses their older version, which isn't as sleek as the modern one, but everything is cleanly labelled and easy to access. In fact, there's even one thing that you don't see in NetEnt titles nowadays: a big button that allows you to preview the feature and see what it looks like. This is something that would get players excited for the real thing, and it could be something the developers might want to consider bringing back.

The lower paying bracket of icons include 10, J, Q, K and A, which look carved out of stone with intricate rune patterns all over them. The rest are stone carvings of animals on coins — the snake, the wolf, the bull, the owl and the deer — all with a distinct shape and colour fitting of their status as objects of reverence for the druids of old.

Collecting three or more Scatters will reward ten free spins and a pass through the stone field the druids take good care of. There are twenty stones, and the amount you can pick through depends on how many Scatters activated the feature. Among the prizes you can find are extra Wild symbols which will make all owl and deer icons into Wilds, Wild Reels that will fill the second or fourth reel with Wilds, a multiplier increase from x1 to x2, and extra free spins, up to a maximum of 10 more.

Despite having just one feature on offer, NetEnt's release takes it and runs, achieving a great deal with that one bonus where a lot of titles have several that don't seem to go anywhere. Every time you hit the bonus, odds are, it's going to turn out a little bit differently, and a good combination can put you in a serious surplus — though it naturally requires a good amount of luck to get to that point.

Secret of the Stones offers medium volatility with an RTP of 96.7%. For the year it was launched, the visuals are well done, the inclusion of a feature preview was a nice addition, and the winning potential certainly tickled our fancy.

Frequently Asked Questions

What is the RTP of Secret of the Stones slots?

Secret of the Stones has an RTP (Return to Player) of 96.7%, which is above average for a NetEnt druid-themed video slot. The game is medium volatility with 25 flexible paylines. The randomised stone-picking modifier during free spins — which can deliver Wild reels, multipliers, extra spins or new Wild symbols in varying combinations — is what drives the game's highest-value sessions.

Can I play Secret of the Stones slots for real money online?

Yes, Secret of the Stones real money slots are available at licensed NetEnt online casinos across the UK, Europe and other regulated markets. Its 96.7% RTP and medium variance make it a solid real money option for players who enjoy Celtic-themed slots with a single richly modifiable free spins feature rather than multiple separate bonus rounds.

How does the stone-picking feature work in Secret of the Stones?

When 3 or more Scatters trigger free spins, players are taken to a druidic stone field containing 20 stones. The number of stones you can select depends on how many Scatters triggered the feature. Each stone reveals one of four modifiers that will apply during the free spins: extra Wild symbols (converting owl and deer icons to Wilds), Wild Reels (filling reel 2 or 4 entirely with Wilds), a x2 multiplier boost, or extra free spins (up to 10 additional). Multiple modifiers can be collected in one trigger.

What symbols act as Wilds during Secret of the Stones free spins?

In the base game, there is a standard Wild symbol. During free spins, if you pick the Extra Wilds modifier from the stone field, all owl and deer symbols on the reels are converted into Wild icons for the duration of the bonus. Combined with the Wild Reel modifier that can fill an entire column with Wilds, it is possible to have large portions of the reel set covered in Wild substitutions, creating winning combinations across many of the 25 paylines simultaneously.

Can free spins be re-triggered in Secret of the Stones?

Yes — the stone-picking feature includes an option to receive extra free spins, up to a maximum of 10 additional spins on top of the initial 10 awarded. The number of extra spins available depends on which stone you select during the picking round. While you cannot re-trigger indefinitely, a single stone selection can meaningfully extend the bonus session beyond the initial 10 free games.

What is the feature preview button in Secret of the Stones?

Secret of the Stones includes a dedicated feature preview button — a relatively unusual addition that lets players see what the free spins bonus looks like before committing real money to trigger it. This was part of NetEnt's older interface design and is rarely seen in modern slots. It functions as a demonstration mode for just the bonus round, allowing players to understand the stone-picking mechanic and its possible outcomes without needing to spin until a natural trigger occurs.
