Moon Princess is a fantasy-themed online slot developed by Play’n GO and released on July 27, 2017. Inspired by Japanese anime aesthetics and magical fantasy adventures, the game introduces three princesses named Love, Star and Storm, each possessing unique abilities that influence the outcome of individual spins.
Unlike conventional five-reel slots, Moon Princess uses a 5×5 grid where matching symbols create wins horizontally or vertically. Winning symbols disappear, new symbols cascade into position and additional combinations can form during the same round.
The game combines this cascading system with special character abilities, a Princess Trinity feature and free spins that can produce increasingly valuable combinations.
With a standard RTP of 96.50%, high volatility and a maximum advertised payout of 5,000× the original stake, Moon Princess offers an unusual combination of accessible matching mechanics and potentially substantial payouts.
In this Slotinia review, we examine Moon Princess’s gameplay, symbols, special features, free spins, mathematical characteristics and overall experience.
Moon Princess Theme and Design
Moon Princess takes place in a magical fantasy world inspired by anime and Japanese pop culture.
The game’s visual identity revolves around three princesses, each representing a different magical power.
Love, Star and Storm are illustrated in a colourful anime style, with distinctive costumes, expressions and visual effects.
The background features a mystical environment with bright colours and fantasy-inspired details.
Rather than relying on traditional casino imagery, Moon Princess creates an atmosphere closer to a fantasy adventure.
The soundtrack complements this presentation with energetic music, character voices and sound effects that accompany important gameplay events.
Each princess has a recognisable visual identity, making it easier to understand which character is currently active.
The combination of colourful graphics, animated characters and cascading symbols gives Moon Princess a distinctive appearance compared with more traditional online slots.
Despite its relatively compact playing area, the game can become visually busy when several consecutive wins and special abilities activate.
This is particularly noticeable during Princess Trinity and the free spins feature.
Moon Princess Gameplay and Winning Mechanics
Moon Princess is played on a 5×5 grid containing 25 symbol positions.
Although the game information may describe five reels and five rows, its winning system differs from traditional paylines.
Instead of requiring matching symbols across consecutive reels, Moon Princess awards wins when three or more identical symbols connect horizontally or vertically.
This creates a grid-based matching system.
A qualifying combination can form in different parts of the playing area, rather than only along predefined paylines.
Symbols can also contribute to more than one winning combination when the relevant conditions are met.
After a win is awarded, the winning symbols disappear from the grid.
The remaining symbols move downward and new symbols enter the empty positions.
This process is known as cascading or tumbling symbols.
If the new arrangement creates another qualifying combination, an additional win is awarded without requiring another paid spin.
The cascading sequence continues until no further winning combinations appear.
Moon Princess also features an increasing win multiplier during consecutive cascades.
This makes extended winning sequences particularly important because later combinations can become more valuable than earlier ones.
However, the multiplier resets when the relevant sequence ends, except where specific bonus rules provide otherwise.
Moon Princess Symbols
The game’s symbols reflect its fantasy theme.
Lower-paying symbols include colourful objects such as hearts, stars, bells and moon-inspired icons.
The higher-paying symbols include the three princesses.
These character symbols have an additional role because qualifying princess combinations contribute to the Princess Trinity meter.
This means that the princesses are important not only for their direct payout values but also for their ability to activate special gameplay.
Wild Symbol
The Wild symbol is represented by a full moon.
Wilds substitute for regular paying symbols when forming eligible winning combinations.
They can therefore help complete combinations that would otherwise fail to qualify.
Wild symbols also interact with other features, including the game’s special princess mechanics.
The precise effect of a Wild depends on its position and the current gameplay situation.
Cascading Wins and Multipliers
Cascading wins are central to the Moon Princess experience.
Every qualifying combination removes symbols from the grid and allows new symbols to enter.
This creates the possibility of several consecutive wins during a single paid round.
The game’s multiplier system adds another layer to these sequences.
As additional cascades occur, the multiplier increases and can improve the value of subsequent winning combinations.
A successful sequence may therefore become increasingly valuable as it progresses.
However, the existence of a multiplier does not guarantee additional wins.
New symbols must still form qualifying combinations.
This interaction between cascading symbols and increasing multipliers is one of the game’s defining characteristics.
It also helps distinguish Moon Princess from conventional five-reel slots where each spin is normally evaluated without a continuing cascade sequence.
Girl Power Feature
Girl Power is one of Moon Princess’s most recognisable mechanics.
Each of the three princesses possesses a different magical ability.
These abilities can influence the playing area and create additional opportunities for winning combinations.
The active princess is displayed alongside the grid.
Princess Love
Love’s ability changes selected symbols to help create matching combinations.
By transforming symbols, the feature can improve the arrangement of the playing area and potentially create additional wins.
The effect is particularly useful when several symbols are close to forming a qualifying combination.
Princess Star
Star introduces Wild symbols into the playing area.
Because Wilds can substitute for regular paying symbols, they may complete existing combinations or help create new ones.
The value of this ability depends on the positions of the Wilds and the surrounding symbols.
Princess Storm
Storm removes selected symbols from the grid.
This allows other symbols to move into new positions and can potentially create additional winning combinations.
Her ability works particularly well with the cascading system because removing symbols changes the arrangement of the playing area.
How Girl Power Affects Gameplay
The three abilities approach the same objective in different ways.
Love transforms symbols, Star introduces Wilds and Storm removes symbols.
Together, they create more varied gameplay than a standard cascading slot.
However, activating a special ability does not guarantee a winning result.
The outcome still depends on the symbols and combinations produced.
Princess Trinity Feature
Princess Trinity is another major feature in Moon Princess.
The game includes a meter that fills when qualifying combinations involving the princess symbols appear.
Different combinations contribute different amounts of progress.
Three matching princess symbols fill one section of the meter, four matching symbols fill two sections and five matching symbols fill three sections.
Wild symbols can also contribute to qualifying princess combinations under the game’s rules.
Once the meter is fully charged, Princess Trinity activates.
During this feature, the princesses use their special abilities in succession.
This creates additional opportunities to modify the grid and potentially generate new winning combinations.
The feature is particularly interesting because it combines all three character mechanics rather than relying on a single princess.
Love can transform symbols, Star can introduce Wilds and Storm can remove symbols.
The resulting sequence may create additional cascades and multiplier progression.
However, the feature remains dependent on the combinations produced.
Princess Trinity adds variety to the base game and provides a separate objective beyond simply collecting ordinary symbol wins.
Moon Princess Free Spins
Free spins represent the game’s main bonus feature.
Unlike traditional slots that require a specific number of Scatter symbols, Moon Princess uses a grid-clearing mechanic.
When the playing area is cleared under the game’s rules, the free spins feature can activate.
The player then chooses one of the three princesses.
Each princess offers a different bonus configuration, including a different initial number of free spins.
The selected princess also determines the special ability associated with the feature.
This creates an element of choice before the bonus begins.
Princess Abilities During Free Spins
The three princesses provide different gameplay effects during the bonus.
Love can introduce Wild symbols to the grid.
Star can increase the value of qualifying wins through her multiplier-related ability.
Storm can remove symbols and create opportunities for additional combinations.
These abilities can activate during non-winning spins, helping modify the grid before the round continues.
The effects differ from ordinary base-game interactions and contribute to the bonus’s distinctive structure.
Persistent Multiplier
One of the most important differences between the base game and free spins is the multiplier system.
During free spins, the multiplier can carry over between rounds rather than resetting after every completed sequence.
This creates the possibility of building a larger multiplier as the feature progresses.
The multiplier can reach 20×.
However, reaching the maximum multiplier is not guaranteed.
Additional Free Spins
The free spins feature can also be extended.
Filling the relevant meter can award additional spins, subject to the game’s limits.
The maximum number of free spins available is 20.
This gives the feature additional progression beyond its initial allocation.
Clearing the Grid During Free Spins
Clearing the grid during the free spins feature awards an additional prize worth 100× the total stake.
This creates another objective within the bonus.
The combination of character abilities, a persistent multiplier and grid-clearing rewards makes the free spins feature one of Moon Princess’s most elaborate mechanics.
Nevertheless, the bonus can still produce relatively small payouts when favourable symbol combinations fail to appear.
Does Moon Princess Have a Bonus Buy?
Moon Princess does not include a direct Bonus Buy feature.
Players cannot purchase immediate access to free spins through a dedicated feature-buy option.
Instead, bonus features are activated through the game’s regular mechanics.
This is consistent with the general approach of Play’n GO, which is known for placing greater emphasis on naturally triggered bonuses.
Players who prefer traditional feature activation may appreciate this approach.
However, those who specifically want to purchase bonus rounds will not find that option in Moon Princess.
Moon Princess RTP
Moon Princess has a standard theoretical Return to Player of 96.50%.
RTP represents the percentage of total wagers that a slot is mathematically designed to return over a very large number of rounds.
At the standard configuration, a 96.50% RTP corresponds to a theoretical house edge of 3.50%.
However, this does not mean that a player will receive exactly 96.50% of their wagers back during an individual session.
Actual results can differ significantly from the theoretical average.
Moon Princess is also available with alternative RTP configurations.
The documented RTP settings include:
- 96.50%
- 94.51%
- 91.49%
- 87.50%
- 84.50%
These differences are important.
A casino offering Moon Princess at 84.50% RTP provides a substantially different theoretical return from one offering the standard 96.50% version.
Players should therefore check the game’s information menu at their chosen casino before playing.
The RTP displayed within the actual game is more relevant than a general figure quoted in a review.
Moon Princess Volatility
Moon Princess is classified as a high-volatility slot.
High volatility means that payouts can vary considerably between individual rounds.
The game may produce periods of relatively small returns, interrupted by more valuable sequences or bonus features.
Its mathematical model places importance on cascading combinations, multiplier progression and the free spins bonus.
These features can contribute to larger payouts when favourable conditions occur.
However, high volatility also means that players should not expect consistently large returns.
Even when special abilities activate, they do not guarantee profitable outcomes.
The game’s official hit frequency is not disclosed in the referenced specifications.
It is therefore not possible to provide a verified percentage describing how often individual spins produce winning combinations.
Moon Princess Maximum Win
Moon Princess offers a maximum advertised payout of 5,000× the original stake.
For example, a 5,000× result would correspond to 5,000 units of currency for a stake of 1 unit.
The maximum payout is connected to the game’s mathematical model and its combination of cascading wins, special abilities and bonus features.
However, the maximum win is a theoretical limit rather than an expected outcome.
Achieving the maximum payout is not guaranteed, and its probability is not disclosed in the referenced game information.
Players should evaluate the maximum win alongside RTP, volatility and the overall gameplay structure.
Moon Princess Betting Range
Moon Princess supports a betting range from 0.20 to 100 per round in the referenced configuration.
The available currency and betting options depend on the casino.
This range allows players to select different stake levels according to their preferences and budgets.
However, changing the stake does not change the underlying randomness of the game.
A higher stake increases the monetary value of potential payouts but also increases the amount at risk.
Players should choose a stake that fits a predetermined entertainment budget.
Moon Princess Mobile Compatibility
Moon Princess is available on compatible mobile devices, including smartphones and tablets.
Its 5×5 grid adapts to smaller screens while preserving the game’s main mechanics.
The princess characters, cascading symbols and special effects remain central to the mobile experience.
Because the game uses a relatively compact grid, the basic matching mechanics are generally easy to follow.
However, the number of animations and special effects can make some sequences visually busy on smaller devices.
Performance may vary depending on the browser, device and casino platform.
The underlying RTP and mathematical rules are not changed simply by switching between desktop and mobile play.
What Makes Moon Princess Different?
Moon Princess stands out through its combination of several mechanics.
The first is its grid-based matching system.
Instead of traditional paylines, the game uses horizontal and vertical symbol connections.
The second is its cascading structure.
Winning combinations disappear and new symbols enter, potentially creating additional wins during the same round.
The third is the Girl Power system.
Love, Star and Storm each have a different ability, giving the game more variety than a conventional Wild-based slot.
Princess Trinity adds another layer by combining the characters’ powers.
Finally, the free spins feature introduces character selection, a persistent multiplier and additional grid-clearing rewards.
Together, these mechanics create a distinctive slot that feels different from many traditional five-reel releases.
Slotinia’s Verdict on Moon Princess
Moon Princess is one of the more distinctive releases from Play’n GO’s earlier portfolio.
Its anime-inspired presentation immediately separates it from traditional fruit slots and conventional adventure-themed games.
However, its strongest qualities are found in the gameplay mechanics.
The combination of a 5×5 grid, cascading wins and three different princess abilities creates a system that offers more variety than a standard paylines slot.
Girl Power adds unpredictability to individual rounds, while Princess Trinity provides an additional progression mechanic.
The free spins feature is particularly interesting because it introduces character selection and a persistent multiplier.
These elements make the bonus more elaborate than a conventional free spins round.
The standard RTP of 96.50% is another positive characteristic, although the existence of substantially lower RTP configurations is an important consideration.
High volatility also means that Moon Princess will not appeal equally to every player.
Those who prefer frequent smaller payouts or simpler gameplay may find the experience less suitable.
Nevertheless, Moon Princess remains a notable example of Play’n GO’s ability to combine recognisable characters with original slot mechanics.
Its distinctive theme, cascading system and interconnected bonus features make it an interesting choice for players who enjoy grid-based slots with several layers of gameplay.
Responsible Gambling
Moon Princess is a game of chance involving financial risk. Its RTP, volatility and maximum advertised payout do not guarantee any particular outcome. Players should verify the game’s RTP at their chosen casino, establish a budget before playing and avoid chasing losses. Gambling should always be treated as entertainment rather than a source of income.
