Moon Princess Trinity Slot Review
Play’n GO’s Moon Princess franchise remains a cornerstone of the modern slot landscape, entertaining players consistently since 2017. Moon Princess Trinity, released in March 2023, marks the fourth instalment in this celebrated series, introducing a fresh interpretation of the anime-inspired aesthetic whilst fundamentally reimagining the bonus structure. Rather than pursuing the increasingly common path of chasing ever-larger multipliers—as seen in companion titles like Moon Princess 100 (15,000x) and Moon Princess Origins (20,000x)—Trinity charts its own course with a more measured approach to volatility and win potential.
Base Game & Features
Trinity operates on a 5×5 grid using cluster pays mechanics—a departure from traditional paylines that requires 3 or more matching symbols to connect horizontally or vertically adjacent. When winning combinations form, those symbols vanish and remaining symbols cascade downward to fill empty spaces, creating the potential for multiple wins from a single spin. This cascading system forms the mechanical foundation of the game’s excitement, with each cascade building anticipation for additional winning combinations.
Win Multiplier & Cascade System
What sets Trinity apart from other cluster pays games is the win multiplier system. Blue-highlighted positions frame random areas of the grid. Each time a winning combination lands on one of these marked positions during a cascade, the multiplier increases by +1. Unlike many competing titles, this multiplier builds indefinitely throughout cascades, creating genuine potential for significant payouts during productive spins. Between standard paid spins, the multiplier resets to 1x, maintaining engagement and preventing excessive volatility swings.
Wild Symbols & Feature Triggers
Every winning combination generates a wild symbol that persists on the grid, substituting for all paying symbols to help form additional wins across multiple cascades. This wild-generation system creates natural progression through cascades, as wilds accumulate and contribute to subsequent winning patterns. The game employs no traditional scatter symbol—a design choice that pushes focus entirely onto the Trinity bonus mechanic as the sole special feature trigger.
Girl Power Modifiers (Base Game)
On non-winning spins during base gameplay, Girl Power modifiers can trigger randomly, injecting variability into otherwise dead spins. There are three distinct modifiers:
- Love: Transforms an entire set of matching symbols on the grid into a different symbol type, potentially creating new winning combinations.
- Star: Randomly distributes 1-2 wild symbols onto the grid, expanding win potential across cascades.
- Storm: Removes two sets of lower-paying symbols and replaces them with higher-paying symbols or additional wilds.
These modifiers provide meaningful rescue mechanics on dry spins, though their random nature means relying on them for consistent returns is not advisable. Still, when they activate—particularly Storm, which can inject an entire wild grid refreshment—the experience feels rewarding enough to maintain interest during base gameplay.
Bonus Features & Free Spins
Moon Princess Trinity abandons the traditional free spins format in favour of the Trinity Bonus—a reimagined feature that replaces scattered bonus symbols with a progression metre. Rather than spinning a wheel or selecting free spin counts, Trinity operates through a golden metre positioned adjacent to the main grid. This shift represents a deliberate design choice, moving away from expectation-building bonus mechanics towards more integrated, progression-based gameplay.
Trinity Feature: Metre & Activation
The Trinity Bonus metre fills by landing matching princess symbols during base spins. Landing three, four, or five matching princess symbols fills 1, 2, or 3 metre segments respectively. Once the metre reaches full capacity, the Trinity Bonus activates—a single free round where all three Girl Power modifiers (Love, Star, Storm) become active on each symbol drop that doesn’t form an immediate win.
During this bonus round, the win multiplier does not reset if the feature retriggered—a distinction that sets Trinity apart from many competitors. This means a retrigger during an already-active bonus round allows the multiplier to continue climbing, creating opportunities for genuinely substantial payouts. The feature can retrigger multiple times if the grid is cleared during the Trinity round, with each retrigger extending the bonus session and multiplier accumulation.
Grid Clearing & Modifiers During Bonus
One of Trinity’s most visually satisfying mechanics is the grid clear bonus. When all 25 grid positions are cleared of symbols during a spin, the player receives 50x the current stake. This award applies whether clearing occurs during base gameplay or bonus mode. The visual feedback—watching the final symbols vanish followed by the animated golden “50x” declaration—ranks amongst the most rewarding experiences in modern cluster pays design.
Critically, during the Trinity bonus round, a Girl Power modifier is guaranteed to activate on every symbol drop that doesn’t form an immediate win. This creates a frenetic, fast-paced experience where the screen is almost constantly animated with transformations, wild additions, and symbol replacements. The intensity differs markedly from base gameplay, making Trinity’s bonus feel genuinely distinct rather than a simple acceleration of existing mechanics.
Bonus Trigger Frequency & Volatility
Trinity’s high volatility manifests primarily in bonus trigger frequency. Community feedback consistently identifies one notable limitation: the Trinity metre can take considerable time to fill during standard play, and when it does trigger, payouts often remain modest unless cascades align favourably or multipliers build substantially. Most bonuses pay under 50x stake, which—given the game’s 4,000x max win potential—represents relatively conservative payouts. This characteristic suits players comfortable with extended dry spells in pursuit of rare but genuine big-win opportunities, though it may frustrate those seeking frequent bonus engagement.
Our Honest Verdict
Moon Princess Trinity represents a curious middle ground within the Moon Princess franchise—neither a revolutionary advancement nor a step backward, but rather a lateral move that trades certain features for others. The anime-inspired visuals remain stunning, with character designs showcasing intricate details and vibrant colours that immediately appeal to series enthusiasts. The gameplay feels demonstrably smoother than predecessors, and the cluster pays mechanic combined with the non-resetting multiplier system during Trinity retriggers creates legitimate mechanical depth.
However, the design choices reveal specific compromises. The removal of traditional free spins in favour of the Trinity metre—whilst innovative—narrows player agency. Previous Moon Princess iterations allowed selecting favourite princess modifiers during bonus rounds; Trinity activates all three sequentially, removing personalisation. More significantly, the 4,000x max win positions Trinity as the lowest-potential title in the current series lineup. Compared to the original’s 5,000x, this represents a 20% reduction in ceiling, making the game unsuitable for players specifically chasing maximum multiplier potential.
Trinity appeals most clearly to anime aesthetics enthusiasts and established Moon Princess fans seeking a fresh mechanical interpretation. The cluster pays/cascading system with modifiers delivers engaging base gameplay between bonus rounds, and the guaranteed Girl Power activation during bonus modes ensures productive, animated sequences. Players comfortable with high volatility and willing to weather extended bonus-drought periods will find genuine entertainment value, particularly given the technical polish and visual quality on display.
Those expecting this instalment to supplant the original or significantly advance the series mechanics may find the execution incremental rather than revolutionary. The game occupies space confidently within the franchise, offering a respectable entry rather than a definitive evolution. For casual players new to the series, starting with the original Moon Princess or Moon Princess 100 might prove more satisfying given their higher max win potential and simpler bonus structures. Trinity works best as a deliberate choice—particularly by existing series devotees—rather than as a standalone recommendation.
Moon Princess Trinity FAQs
What is the RTP of Moon Princess Trinity?
Moon Princess Trinity is available in five different RTP versions: 87.20%, 91.20%, 94.20%, 96.20%, and 84.20%. The highest RTP is 96.20%, though most online casinos strategically offer one of the lower-paying versions (87.20%-94.20%) to increase their profit margins. The difference between the lowest (84.20%) and highest (96.20%) RTP is approximately 12%, which significantly impacts win frequency and overall player returns.
What is the max win in Moon Princess Trinity slot?
Moon Princess Trinity offers a maximum win of 4,000x the bet. This represents the lowest ceiling among current series titles: the original Moon Princess offers 5,000x, Moon Princess 100 delivers 15,000x, and Moon Princess Origins reaches 20,000x. Whilst 4,000x remains a substantial multiplier, players specifically chasing maximum win potential may find other franchise entries more appealing.
How volatile is Moon Princess Trinity?
Moon Princess Trinity is a highly volatile slot game played on a 5×5 grid using cluster pays mechanics. High volatility means wins are less frequent but potentially larger when they occur. The game features extended dry spells between bonus triggers, with most payouts remaining under 50x stake when bonuses do activate. This volatility suits players comfortable with bankroll fluctuation in pursuit of occasional big-win cascades.
What are the bonus features in Moon Princess Trinity?
Moon Princess Trinity features the Trinity Bonus (which replaces traditional free spins), Girl Power modifiers (Love, Star, Storm), cascading wins, a win multiplier system, and a grid-clearing feature that awards 50x stake. There is no traditional scatter symbol or free spins bonus in the conventional sense. The Trinity Bonus triggers by filling a golden metre with matching princess symbols and activates all three Girl Power modifiers sequentially during the free round.
How do Girl Power modifiers work in Moon Princess Trinity?
On non-winning spins, Girl Power modifiers can randomly trigger during base gameplay: Love converts an entire set of symbols on the grid (allowing selection of which symbol type to convert to), Star randomly adds 1-2 wilds onto the grid, and Storm removes two sets of lower-paying symbols and replaces them with high-paying symbols or additional wilds. During the Trinity Bonus, a Girl Power modifier is guaranteed to activate on every symbol drop that doesn’t form an immediate win, creating frequent visual feedback and gameplay intensity.
What is the Trinity Bonus in Moon Princess Trinity?
The Trinity Bonus is triggered by filling a golden metre located adjacent to the main grid. Landing 3, 4, or 5 matching princess symbols fills 1, 2, or 3 metre segments respectively. Completing the metre activates the trinity bonus round where all three Girl Power modifiers (Love, Star, Storm) are active sequentially. Critically, the win multiplier does not reset if you trigger a retrigger during the bonus round, allowing continued multiplier accumulation. The feature can retrigger multiple times if the grid is cleared, with each retrigger extending the bonus session.
How do you play Moon Princess Trinity slot?
Moon Princess Trinity is played on a 5×5 grid with cluster pays mechanics. To win, you need 3 or more matching symbols adjacent horizontally or vertically. Winning symbols disappear and are replaced by falling symbols (cascading wins), which can generate additional wins with an increasing multiplier. The win multiplier increases by +1 for each cascade landing on blue-highlighted grid positions. The bet range extends from 0.10 to 100, and the maximum win is 4,000x your bet. Casino gameplay includes random Girl Power modifier activation during non-winning spins, adding variability and rescue mechanics.
Does Moon Princess Trinity have free spins bonus?
Moon Princess Trinity does not have a traditional scatter symbol or free spins bonus in the conventional sense. Instead, it features the unique Trinity Bonus that activates when you fill the golden metre with matching princess symbols. The bonus provides a single free round where all three Girl Power modifiers (Love, Star, Storm) are active sequentially, creating an intensely animated bonus experience. The ability to retrigger by clearing the grid means the feature can extend across multiple rounds whilst maintaining multiplier accumulation.
