Atlantis Megaways is a maritime-themed Megaways slot developed by Yggdrasil Gaming. It transports players to an underwater or oceanic realm, with treasure chests, coral reefs, dolphins, mermaids, and shipwrecks populating its reels. Unlike many Megaways titles tied to mythology or fantasy, Atlantic Megaways leans heavily on aquatic ambiance and sea legends.
The game supports up to 117,649 Megaways, rolling cascades, a jackpot-style mechanic in some markets, and several bonus-enhancing features such as “Sea Spins” and mystery treasure chests. Its variance is on the higher side—structured to reward players who tolerate swings. The design goal appears to be a balance between frequent action and occasional large payouts via features.

Theme, Art & Audio
Theme & Symbolism
The oceanic theme prevails: sea creatures (seahorses, dolphins, octopi), shipwreck artifacts, sunken helm, treasure chests, and gemstone icons. The symbol palette is rich in blues, aquamarines, and coral tones.
The background shows a sunken ship submerged over ocean floor with drifting sand particles and aquatic plant life. Occasional fish or schools swim overhead, giving a sense of depth and motion.
Visual Treatment
Yggdrasil’s design standard is high: crisp animations, smooth symbol transitions, and subtle lighting effects. Cascading wins are visually celebrated with bubbles, light beams, and symbol shake. The UI cleanly frames Megaways counters, bet controls, win meters, and mobile-friendly options.
Symbols enlarge slightly during cascade chains to help readability. Mystery chests glow when holding features are possible, serving as visual lures.
Sound & Atmosphere
Ambient underwater audio with soft strings, ocean murmurs, and occasional harp glints set a calming background. Winning combos produce delicate plucks, and feature triggers bring up thematic crescendos. During bonus modes, sound intensifies to deepen immersion.
Overall, the audio design supports long sessions without overwhelming repetition.
Core Mechanics & Feature Breakdown
Megaways & Cascades
The slot uses a standard Megaways engine: reels 1–6 display 2–7 symbols each spin. Winning combinations are evaluated left to right on consecutive reels. Upon any win, contributing symbols are removed and replaced via cascades, allowing multiple wins within a single spin.
Sea Spins / Free Spins Feature
A primary bonus mode is Sea Spins (free spins) triggered by scatter symbols (often seashell or star symbols). Typical structure:
- Landing 4 scatters awards 10 free spins
- Each additional scatter adds extra spins
- During Sea Spins, a multiplier is in effect which increases by +1 per cascade, and does not reset between spins
- Additional scatter symbols appearing during free spins award further spins (retrigger)
This structure rewards cascade momentum and extended play.
Mystery Treasure Chests & Bonus Enhancers
Scattered mystery chests may land randomly or during certain spins. These chests open to reveal wilds, multipliers, symbol upgrades, or extra cascade chains. In some builds, these chests interact with the free spins mode, boosting its value.
In some operator versions, a jackpot symbol is tied to a chest meter that, when filled, triggers a jackpot pick bonus.
Jackpot / Progressive Mechanic (Optional)
Certain licensed builds of Atlantic Megaways include a progressive jackpot layer. The jackpot is funded via a small rake on each spin. The activation may occur via a chest pick bonus or random jackpot trigger. Not all versions include this – availability depends on the licensing territory and the operator.
Mathematics & Performance Profile
RTP & House Edge
Common RTP variants for Atlantic Megaways span 96.10% to 96.25%, depending on region or operator. Yggdrasil typically offers a single unified RTP per jurisdiction.
Volatility & Hit Behavior
Volatility is high; base-game wins are moderate and often small, while most of the value lies in cascading multipliers and bonus rounds. Because the multiplier carries in Sea Spins, free spins accumulate value more than base play.
Maximum Payout
In non-jackpot installations, the max non-progressive cap often sits around ~10,000× the stake (this is an approximate value used by reviewers). With progressive variants, theoretical ceilings scale with jackpot pools.
Feature Frequency
Sea Spins triggers are less frequent, leading to longer base-game expectation time. Mystery chest occurrences and cascade chains with high multipliers are more sporadic but high impact.
Player Experience & Flow
- Base-game pacing: Regular cascades reward low-level wins; wilds and chests build into potential features.
- Multiplier climb: As cascades chain, the multiplier quickly escalates in free spins rounds, causing large spin outcomes late in the feature.
- Feature suspense: Mystery chests and scatter combos maintain tension even outside free spins.
- UI continuity: Always-visible Megaways counter, chest meter, and multiplier display keep players informed of state progression.
Players report that watching the multiplier climb and seeing cascading symbols pay off in a late sequence is one of the most satisfying experiences in the game.
Strategy & Bankroll Considerations
- Large bankrolls advised: High volatility means many spins may offer little; plan for long runs.
- Session capping: Limit risk exposure by stopping after a certain loss threshold.
- Stake moderation: Smaller stakes extend play and allow more feature hunts; large stakes speed feature access but risk bankroll exhaustion.
- Demo testing: Use the free demo to note chest frequency, multiplier growth rate, and scatter triggering patterns before staking real money.
Strengths & Weaknesses
Strengths
- Beautiful aquatic theming and polished presentation.
- Cascade + multiplier in free spins yields compelling feature dynamics.
- Mystery treasure chest adds unpredictability and surprise elements.
- Potential for progressive versions increases upside.
Weaknesses
- High volatility may frustrate risk-averse players.
- Chest/jackpot features may appear rarely, giving uneven payout distribution.
- Some mobile layouts may feel crowded when grid and UI elements overlay.
- Versions without jackpot lack the “big win chase” appeal some players seek.
Demo & Real-Money Availability
The demo version is often available on Yggdrasil partner sites and slot portals; this allows players to test mechanic behavior, chaining potential, chest occurrences, and multiplier growth in a risk-free environment.
For real-money play, verify whether the operator supports the progressive jackpot version or the standard variant. Also confirm the implemented RTP and availability of chest features.
Conclusion
Atlantic Megaways is a mature and visually compelling aquatic Megaways experience enriched with cascading wins, multiplier mechanics, and optional jackpot layers. Its high volatility and layered bonus structure favor players who chase big feature outcomes over steady base returns. As part of your slot suite, this game is a strong pick for audiences seeking immersive themes, tension-filled mechanics, and upside potential. It pairs well with cautionary bankroll tools and should be presented with clarity about variance risk.
