Inside NetEnt's Celtic Stone Circle

Secret of the Stones is a NetEnt video slot built around an ancient Celtic theme, set among carved standing stones and weathered runes rather than the usual leprechaun-and-shamrock clichés. The game was relaunched in its current "Max" form by NetEnt, which lets players choose between a calmer classic mode and a punchier high-octane mode from the same interface. It runs on a familiar five-reel grid but keeps the presentation moody and atmospheric, with stone symbols that light up as wins land.

Reels, Grid and Paylines

The game uses a 5x3 layout, meaning five reels and three rows on screen at once. Wins are paid across 25 fixed paylines running left to right, so every spin plays all lines and there is nothing to switch on or off. Lower-value symbols are rendered as carved rune tablets, while the premium symbols lean into the mystical Celtic artwork. It is a straightforward structure that keeps the focus on the bonus mechanics rather than on configuring lines.

RTP and Volatility

In its Max configuration, Secret of the Stones carries an RTP of 96.81%, which sits a touch above the common 96% benchmark for online slots. The classic mode plays at a lower, steadier volatility, while the Max mode raises the variance for bigger swings. On Slottomat the game is listed at medium volatility, a reasonable middle ground that reflects regular mid-sized hits without the extended dry spells of a hardcore high-variance title. The exact rhythm you feel will depend on which mode you choose to play.

Wilds, Scatters and Free Spins

The core feature set is classic NetEnt. Wild symbols substitute for regular symbols to help complete winning combinations, while scatter symbols are the key to the bonus. Landing enough scatters triggers the free spins round, where the game's bigger potential lives. Before the free spins begin, an interactive stone-picking step lets you influence the round, revealing extras such as wild reels and multipliers. Those multipliers and added wilds are what turn ordinary free spins into the standout moments of a session.

Maximum Win Potential

The headline number is the top payout: the Max version of Secret of the Stones can pay up to 25,000x your stake. That is a substantial ceiling and comfortably ahead of the classic mode's smaller cap, which is part of why NetEnt rebuilt the game. As always with a figure like this, it represents the rare best-case outcome driven by the free spins multipliers rather than something you should expect on a typical spin, but it gives the game genuine reach when the features align.

Betting Range

Stakes run from a minimum of 0.25 up to a maximum of 125 per spin. That spread is wide enough to suit cautious players testing the waters at the low end, while still leaving room for higher-stakes spins toward the top of the range. Because the 25 paylines are fixed, your bet adjusts as a single coin value rather than by toggling lines, keeping the betting interface simple.

Playing on Mobile and in Demo

Secret of the Stones is built to run in the browser on desktop and mobile alike, with no download required. The reels, touch controls and bonus picks all scale to phone and tablet screens, so the experience carries over cleanly to smaller displays. You can also try the game in free demo mode at the top of this page, which uses play-money credits and mirrors the real-money version's RTP, layout and features. The demo is the easiest way to learn the stone-picking bonus and see how the two volatility modes differ before deciding which suits you.
