How Secrets of Atlantis Demo Works

Secrets of Atlantis is a video slot designed by NetEnt, one of the top names worldwide for digital slots. This game uses a five-reel, four-row setup with 40 paylines. If you’ve spun Starburst or Ocean’s Treasure, you will recognize that smooth NetEnt engine and the crisp art style. What stands out here is the “both ways” setup, meaning you can match symbols left-to-right and right-to-left, which can catch you off guard in the best way.

• Theme: Underwater Atlantis adventure with mermaids, pearls, jellyfish, turtles, and gems
• Grid: Classic 5×4 reels, 40 fixed lines
• Betting: Adjust coin values and bet level using on-screen controls, all virtual in free sim mode
• Bonus: No traditional scatter symbol, but stacked Mermaid Wilds nudge to fill whole reels and unlock the highlight respin bonus
• Favorites: Colossal respin reels covering reels 2 to 4; coins and gems look especially shiny on spins
• Not my favorite: No free spins in the classic sense, but respins pop up often enough

Settings are super simple. Tweak bet levels, mute sounds, check the paytable, or trigger autospins inside the demo. Free play uses simulated credits, so you can try different bet levels and see which features hit most often.

Secrets of Atlantis RTP & Volatility

The secret sauce here? A generous theoretical RTP of 97.10 percent, which is above the average for online slots. RTP stands for “return to player”, in theory, this is how much is paid out over a very long session. Of course, every spin is random. Nothing you do makes future outcomes more likely, and all spins in the Demo are separate events, just like the real thing.

Secrets of Atlantis rates as a medium volatility slot. In my playthrough, that meant occasional streaks of smaller wins with the odd bigger payout sprinkled in. Colossal Respins can come in bunches or seem to dodge you for a good run, all depending on your luck. Sometimes Mermaid wilds fill the screen, sometimes you will wish they did. Bottom line, expect ups and downs, nothing is ever guaranteed, but the overall risk curve feels pretty fair compared to high volatility “hold-on-for-your-life” slots.

How to Win on Secrets of Atlantis: Symbols & Payouts

Payouts come from lining up three or more of the same symbol on one of the 40 fixed lines. The “both ways” mechanic means wins pay from leftmost or rightmost, doubling your chances compared to standard one-way paylines. The symbols run from high-value gems (blue, green, red) to pearls, turtles, jellyfish, and crabs for smaller wins.

The stacked Mermaid wild is by far the most important symbol. Anytime she lands partially in view on a reel, she nudges to cover it completely, helping complete multiple lines at once. There’s no free spins feature, but hitting highlighted reels on a spin activates the Colossal Respins, where a giant symbol block covers the middle reels for one spin. My biggest simulated win came from a Colossal Respins round that lined up gems and wilds, definitely the most entertaining part for me.

There’s no gamble bonus after wins, just base play and respin action. Bonus rounds triggered for me roughly every 30–40 spins, but it was definitely streaky.

Secrets of Atlantis Jackpot

Secrets of Atlantis does not include a progressive jackpot, so there’s no ever-growing prize pool. Instead, you’re aiming for the max win, which clocks in at 3,200 times your bet per spin. To get anywhere near this, you’ll need a Colossal Respins round packed with premium symbols or wilds across most of the grid. Not an everyday event, but it does add a big-game element when the right symbols line up.

Secrets of Atlantis Strategy

Everyone always seems to be chasing secrets, but here’s the truth: there is no hidden trick or pattern to slot machines. In this Demo, all spins are completely random and using different bet sizes or pressing spin faster does not tilt the odds in your favor. That said, I liked sticking to moderate bet levels just to see more feature triggers over longer play sessions. Keeping an eye on the highlighted reels for unlocked respins was the only “strategy” I could really apply, but of course, the game controls that at random.

The key is to spin for fun, test out how the bonus triggers, and spot what happens when wilds land, no pressure, no stress, no real money bets. Trying to “game” the Demo for a pattern is a bit like staring at storm clouds, hoping to see a dolphin, possible, but not really something you can force.

Secrets of Atlantis Visuals & Design

The design work on Secrets of Atlantis is genuinely eye-catching with its underwater city backdrop, ancient columns, and schools of neat sea creatures. All the icons, from jellyfish to gems, glimmer like they have been fresh polished. Animations are smooth but never overbearing, and wins are clearly shown with bright lines.

Sounds are light and breezy, with soothing water effects and some subtle mermaid sparkles when you score wilds or respins. Everything is easy on the eyes and ears, and controls are clearly laid out, whether you are spinning on mobile or a desktop.

Gamesville Verdict: Is Secrets of Atlantis a Good Slot Machine?

After plenty of simulated spins, I like what Secrets of Atlantis brings to the table. The two-way pays and stacked Mermaid wild keep it fresh, especially if you enjoy slots with feature-packed base play but do not want to babysit endless bonus rounds. The theme hits a nice spot between relaxing and vibrant, pulling you in with its blue-tinted ruins and bright symbols.

For those wanting something similar, check out Starburst for another both-ways pay setup and gem-stacked action. Or try Ocean Magic for an underwater slot with a classic bonus round and a slightly higher volatility punch. And if Atlantis is what brings you here, Neptune’s Gold shows a different take with ancient Greek gods for company. All are available as demos right here at Gamesville.
