At first glance, Moon Princess might look like a pastel-colored tribute to classic anime like Sailor Moon, all cute characters and gentle hues. But don't let the "pretty in pink" aesthetic fool you. This 5x5 grid slot from Play'n GO, released in 2017, is a high-volatility powerhouse packed with cascading wins, a progressive multiplier, and three princesses with unique superpowers that can transform a losing spin into a cascade of victories.
In this Moon Princess review, we'll explore how this beloved game uses its Girl Power features and Princess Trinity meter to create a surprisingly manic and engaging experience. You'll learn about the three princesses—Love, Star, and Storm—and how their abilities differ, how the cascading mechanic with a growing multiplier works, and the path to the 5,000x max win. As always, you can harness the power of the princesses yourself with a Moon Princess demo before you join the fight.
Game Overview: A Magical 5x5 Battlefield
Moon Princess is played on a 5x5 grid. Unlike traditional slots with paylines, wins are formed by landing 3 or more matching symbols adjacent to each other horizontally or vertically (a cluster pays system). The visual presentation is a feast for anime fans: a dreamy, mystical kingdom backdrop and three doe-eyed princesses—Love, Star, and Storm—who cheer you on from the right side of the screen. The symbols are a mix of magical trinkets (hearts, stars, bells, moons) and the princesses themselves.
The game’s math model is rated very high volatility (10/10), promising significant swings. The betting range starts at €0.20 and goes up to €100 per spin.

Gameplay and Paytable: Meet the Princesses
Before the magic starts flying, let's look at the symbols you'll encounter. All wins are formed via clusters.
Low-Paying Symbols: A collection of trinkets—a golden-green charm, a moon star, a heart, and a winged bell.
High-Paying Symbols: The three princesses themselves: Love, Star, and Storm. A cluster of five of any princess pays 10x your bet.
Wild Symbol: A glowing full moon, which substitutes for all regular symbols. A cluster of five wilds pays 50x your bet.
Special Features and Mechanics
The game’s brilliance lies in its multi-layered, action-packed feature set, all driven by the princesses and a clever meter system.
1. Core Mechanics: Cascades and a Growing Multiplier
Cascading Wins: After any winning cluster, those symbols explode and are removed from the grid. The symbols above fall down to fill the empty spaces, and new symbols drop in from the top. This process, known as a cascade, continues as long as new winning clusters are formed.
Moon Wilds: When three symbols are part of a winning combination, the middle position of that combination transforms into a Moon Wild, which can help create further wins.
Progressive Multiplier: This is a key feature. With every new cascade within a single spin, a win multiplier increases by +1. It starts at x1 and can grow continuously, applying to all wins in subsequent cascades. It only resets when the spin ends with no further wins.
2. Girl Power: Random Princess Abilities
On any non-winning spin, one of the three princesses may randomly trigger her special Girl Power feature. The ability used depends on which princess is currently active on the right side of the screen. After using her power, she is replaced by one of the other two.
Love's Power: Transforms one entire set of matching symbols into another type of symbol, potentially creating a new winning cluster.
Star's Power: Adds 1 or 2 extra Wild symbols to random positions on the grid.
Storm's Power: Removes two sets of matching symbols from the grid, causing a massive cascade.
3. Princess Trinity: The Meter Feature
To the left of the grid is the Trinity Meter, divided into three sections. It fills up only when you get winning combinations that include princess symbols (or wilds in combination with them).
Filling the Meter:
A 3-symbol princess combo fills 1 section.
A 4-symbol princess combo fills 2 sections.
A 5-symbol princess combo fills 3 sections.
The Feature: When the meter is completely filled and no further wins are possible on the current spin, the Princess Trinity feature is awarded. You get one free spin where the multiplier resets. During this spin, the three princesses take turns using their Girl Power abilities one after another after each cascade, creating a chain reaction of modifiers and a huge chance for a massive win. After the feature ends, the active princess returns to the one that was on screen before it triggered.
4. Free Spins: Choosing Your Champion
The ultimate goal is to trigger the main Free Spins feature. This happens when you manage to clear the entire grid of all symbols during a single cascade sequence.
Choosing a Princess: You are then presented with a choice of which princess's power to take with you into the bonus round. The number of free spins you receive depends on your choice:
Love: Grants 4 free spins. Her power (transforming symbols) is active on every non-winning spin.
Star: Grants 5 free spins. Her power (adding wilds) is active on every non-winning spin.
Storm: Grants 8 free spins. Her power (removing symbol sets) is active on every non-winning spin.
Enhanced Features: During free spins, the chosen princess's Girl Power triggers on every non-winning spin. Crucially, the progressive win multiplier does not reset between free spins; it continues to grow throughout the entire bonus round, up to a maximum of x20.
Retriggers: The Trinity Meter is also active. Filling it during free spins awards extra spins (4 for Love, 3 for Star, 2 for Storm), up to a maximum of 20 total spins.
Grid Clear Bonus: If you manage to clear the entire grid during the free spins round, you are awarded an instant bonus of 100x your total bet.
Volatility, RTP, and Max Win
Understanding the numbers is crucial before you enter this magical realm. The default Moon Princess RTP is an above-average 96.5% . However, like many Play'n GO titles, this game uses RTP ranges, meaning casinos can adjust it to lower settings. The other possible RTP values are 94.51%, 91.49%, 87.50%, and 84.50% . It is vital to check the game rules at your chosen casino to ensure you are playing the version with the highest RTP.
The very high volatility means you should be prepared for a rollercoaster ride. The reward for enduring the swings is the Moon Princess maxwin of 5,000x your stake. While some reviews suggest this might be an optimistic ceiling, the combination of a persistent multiplier, cascading wins, and powerful princess abilities makes for thrilling, high-potential sessions.
