The underwater theme has been explored countless times in online slots, but Power of Atlantis Trio by Booming Games manages to introduce fresh mechanics that distinguish it from the crowded ocean of similar titles. This 5×3 grid slot with 20 fixed paylines ventures beyond the typical Atlantis-themed experience by integrating an innovative three-way Hold and Win system that operates through a unique Trident and Treasure Chest collection mechanism.
Diving into the Core Mechanics
Power of Atlantis Trio utilizes a standard 5-reel, 3-row layout with 20 non-adjustable paylines. Wins are awarded for matching symbols appearing consecutively from left to right on active paylines. Only the highest win per line is paid, with all winning combinations being added together for the total payout.
The paytable reveals two distinct symbol categories: the higher-value “Majors” and the lower-value “Minors.” The Majors include intricately designed Atlantean characters and artifacts, with the bearded male deity (presumably Poseidon) offering the highest regular payouts at 4.00x for five of a kind. The female deity with pink hair follows at 2.00x for a five-symbol combination. Other major symbols include golden anchors and ornate vases with payouts ranging from 0.30x to 1.20x depending on the number of matching symbols.
The Minors category consists of familiar card symbols (A, K, Q, J, 10) styled with an Atlantean aesthetic, offering smaller payouts between 0.05x and 0.50x for three to five matching symbols.
A crucial aspect of the gameplay is the 10,000x win cap. When total winnings reach or exceed this limit, any active feature immediately terminates, and the maximum 10,000x payout is awarded—creating a definitive ceiling for potential returns.
The Trio System: Where the Innovation Lies
What truly separates Power of Atlantis Trio from other underwater-themed slots is its namesake feature—the Trio system. During base gameplay, Trident symbols of different colors can appear on the reels. When these Tridents land, they fly upward to their corresponding color-matched Treasure Chests positioned above the reels.
This mechanic isn't just visual flair—it serves as the gateway to the game's primary bonus features. Each Treasure Chest, when activated, awards different Hold and Win variations. The genius of the design lies in how these features can combine: activating multiple Treasure Chests simultaneously unlocks enhanced bonus modes.
Hold and Win Variations: A Triple Threat
When triggered, the Hold and Win feature begins with an empty grid and provides three respins. Value symbols appear with multipliers ranging from modest 0.5x up to the grand 1000x. Each new symbol resets the spin counter to three, and the feature concludes when either no spins remain or all positions contain value symbols.
The game's innovation shows in its three distinct Hold and Win variations:
Boost Hold and Win introduces special Boost symbols that can incrementally increase in value with each spin. Starting from 0.5x, these symbols can grow by various increments up to an additional 15x, creating dynamic, evolving values that keep each bonus round unpredictable.
Grid Expand Hold and Win transforms the standard 5×3 grid into a 5×6 layout, dramatically increasing the number of positions available for value symbols. This expansion creates greater potential for filling the grid and accumulating higher total wins.
Collect Hold and Win introduces Collect symbols that gather all values present on the grid whenever they land. Importantly, the collected symbols remain in place, allowing for multiple collections from the same symbols—essentially creating a compounding value system.
Super and Mega Bonus: Where Features Converge
The game's most compelling aspect is how these Hold and Win variations can combine. When two features activate simultaneously, the game awards a Super Bonus. When all three features trigger together, players receive the coveted Mega Bonus.
This layered approach creates substantial depth, as each feature combination produces different strategic considerations. A Grid Expand with Collect symbols creates opportunities for multiple value harvests across an expanded field. Adding Boost symbols to either combination introduces growth potential to already powerful setups.
Feature Buy Option: Immediate Access at a Premium
For players who prefer direct access to bonus features, Power of Atlantis Trio includes two purchase options: Mystery Hold and Win for 75x the current bet and Mega Hold and Win (with all features active) for 250x the current bet.
These options guarantee feature activation but require substantial investment—a trade-off between immediate gratification and the potentially longer path of natural triggering.
Technical Parameters
With a theoretical return to player (RTP) of 95.6% across both base game and bonus features, Power of Atlantis Trio sits within industry standards. The 10,000x win cap establishes a clear ceiling for potential returns, with the game automatically ending any feature once this threshold is reached.
Visual Design and Thematic Elements
The visual presentation draws from classical Atlantis mythology with regal deities adorned in ornate headpieces. The bearded male figure evokes Poseidon's traditional representation, while the female deity with flowing pink hair offers a more stylized interpretation of Atlantean royalty.
Secondary symbols incorporate maritime elements like anchors and ceremonial vessels, reinforcing the underwater empire theme. Even the card symbols receive thematic treatment with gold accents and styling consistent with the Atlantean aesthetic.
The underwater setting utilizes deep blues and aquatic lighting effects that create an immersive atmosphere without resorting to cliché ocean imagery. This deliberate design choice helps distinguish the game visually from the multitude of marine-themed slots available.
Strategic Considerations for Experienced Players
For veteran slot enthusiasts, Power of Atlantis Trio presents several strategic angles worth considering:
The 20 fixed paylines simplify bet management, with wagers affecting only the multiplier applied to line wins rather than the number of active lines. This streamlined approach allows players to focus on bankroll management rather than payline configurations.
The feature buy option presents an interesting risk assessment calculation. At 75x for Mystery Hold and Win or 250x for Mega Hold and Win, players must weigh the guaranteed access against the substantial initial investment. The 95.6% RTP applies to both purchased and naturally triggered features, suggesting no mathematical advantage to either approach beyond personal preference for immediate access.
During Hold and Win features, the reset mechanism that restores spin counts to three with each new symbol creates dynamic sessions where a few well-placed symbols can significantly extend feature duration. This creates natural tension and anticipation with each respin, as a single empty spin brings the feature closer to conclusion while each new symbol extends the opportunity.
Power of Atlantis Trio demonstrates how even well-traveled thematic territory can yield innovative gameplay when approached with fresh mechanical ideas. The triple-feature Hold and Win system with its combination potential creates a multidimensional bonus structure rarely seen in games of similar complexity. The 10,000x win cap establishes clear parameters for potential returns while still offering substantial payout opportunities. With an RTP of 95.6%, the game balances volatility and return expectations in line with industry standards. For players tired of conventional Atlantis-themed slots with predictable bonus rounds, Power of Atlantis Trio presents a refreshingly original approach that emphasizes feature combinations and strategic depth within an accessible framework. The Trio system's ability to create varied bonus experiences through different feature combinations ensures that no two sessions feel identical, providing the novelty and depth that experienced players often seek.
