Atlantis: The Forgotten Kingdom Slot Review
Half Pixel Studios have built a solid reputation for polished game design, and this underwater-themed release showcases their strengths with compelling visual presentation and thoughtfully structured bonus mechanics. Developed in collaboration with Microgaming and released in October 2021, Atlantis: The Forgotten Kingdom occupies a distinctive space in the high volatility market—not chasing trend mechanics, but focusing instead on artistic execution and meaningful player choice within the bonus structure.
Base Game & Features
The game operates on a classic 5×3 grid with 243 ways to win, offering a familiar setup that feels welcoming to players across all experience levels. Mermaid characters serve as premium symbols, presented in stacked arrangements (1×1, 1×2, and 1×3) that add visual variety to the base game while helping form winning combinations across the 243 paylines.
Standard playing card symbols (Ace, King, Queen, Jack) complete the symbol set, creating a straightforward composition that prioritises clarity over complication. The high volatility nature of Atlantis means extended dry spells in base gameplay are common—this is by design rather than oversight, as the game channels most excitement towards its bonus features.
Wild Mermaids Feature
A dedicated mini bonus reel triggers the Wild Mermaids feature, the game’s primary base game modifier. When the mini reel lands on matching mermaid symbols, that specific mermaid becomes a stacked wild across a random main reel, applying multiplier values to any winning combination it participates in:
- Mermaid Queen: 4x multiplier
- Mermaid Beauty: 3x multiplier
- Mermaid Adviser: 2x multiplier
- Mermaid Warrior: 1x multiplier
This feature brings genuine substance to what would otherwise be extended stretches of non-winning spins. The multiplier stacking mechanism ensures that even modest wins receive meaningful enhancement when the Wild Mermaids trigger, though the base game itself remains deliberately restrained to balance the volatility profile.
Scatter Payouts
Pearl Scatter symbols provide baseline payout payouts independent of winning combinations. Two or more scatters deliver immediate returns, with values scaling according to the number landed:
- 2 Scatters: 1x bet
- 3 Scatters: 2x bet
- 4 Scatters: 4x bet
- 5 Scatters: 5x bet
These scatter payouts serve dual purpose—they reward specific symbol combinations while also providing the trigger mechanism for the game’s most significant feature: the Free Spins selection screen.
Atlantis: The Forgotten Kingdom Free Spins
The free spins feature represents where Atlantis truly differentiates itself. Rather than awarding a predetermined number of spins, the game presents players with five distinct free spins options, each offering a unique risk-reward balance. This player agency transforms what could be a passive feature into an active decision point, allowing players to align the bonus structure with their personal playing style and session goals.
Free spins trigger when 3 or more Pearl Scatter symbols land anywhere on the reels, immediately presenting the selection interface. The five available options are:
Free Spins Options
- Queen: 5 free spins with 4x multiplier (highest volatility, genuine max win potential of 7,200x)
- Beauty: 10 free spins with 3x multiplier (balanced high volatility option)
- Adviser: 15 free spins with 2x multiplier (medium volatility, steadier approach)
- Warrior: 20 free spins with 1x multiplier (lowest volatility, consistent base play without enhancement)
- Mystery: Random combination of the above options (unpredictable risk-reward blend)
This structure provides genuinely meaningful choice in bonus strategy. High volatility chasers pursuing the 7,200x maximum can commit to the Queen option’s aggressive 5-spin, 4x multiplier combination. Players seeking steadier returns can select the Warrior’s conservative 20-spin run at base multiplier, whilst the middle-ground Beauty and Adviser options cater to players between these extremes.
Importantly, these spin selections deliver on their promises—the headline-level 7,200x maximum win is genuine, though realising it requires both selecting the Queen option and subsequently hitting multiple stacked Wild Mermaid multipliers during the free spins. It’s achievable but far from guaranteed, accurately reflecting the high volatility classification.
Our Honest Verdict
Rating: 7.5/10
Atlantis: The Forgotten Kingdom occupies an interesting position in the high volatility landscape. Half Pixel Studios have executed a visually compelling underwater experience with legitimately impressive artistic direction—the underwater setting is beautifully realised with its schools of fish, ascending jellyfish, and soothing ambient soundscape that creates genuine immersion rather than relying on flashy theatrics.
The free spins selection mechanism is the standout feature, offering player agency that genuinely matters. The five distinct options provide meaningful choice rather than cosmetic variation, and the volatility scaling across these options feels authentic rather than arbitrary. Once bonuses trigger, there are genuinely strong winning opportunities—the Wild Mermaids multiplier system delivers substance when it activates.
However, the base game feels deliberately constrained to sustain the high volatility profile. The generic card symbol composition combined with extended dry spells between features won’t appeal to players seeking consistent base game action. The game’s simplicity—whilst keeping design focused—means those looking for innovative feature mechanics or mechanical depth beyond the Wild Mermaids system may find themselves underwhelmed. The theme, whilst beautifully executed, doesn’t quite invoke overwhelming player anticipation in the way a true flagship release might.
For high volatility enthusiasts: The five free spins options provide meaningful strategic choice, and the 7,200x maximum win potential is genuine. The RTP of 96.19% sits above industry average, providing fair theoretical returns alongside the volatility thrills you’re seeking.
For casual players: The extended dry spells and deliberate base game simplicity mean you might find more consistent engagement elsewhere. The free spins selection mechanism is excellent, but reaching it consistently requires patience through the high volatility framework.
For aesthetics-first players: The underwater visuals and relaxing soundtrack deliver genuine atmospheric value. If you appreciate slots that prioritise artistic presentation over mechanical innovation, Atlantis delivers genuine visual appeal.
Overall, Atlantis: The Forgotten Kingdom presents a well-crafted but somewhat cautious release from Half Pixel Studios. It will more than suffice for high volatility players who appreciate the five free spins options’ strategic flexibility, though those seeking groundbreaking mechanics or consistent base game engagement should explore other releases in their portfolio.
