Moon Princess Slot Review
Play N’ Go carved out a significant reputation for releasing visually striking games with engaging mechanics, and Moon Princess remains a stellar example of their design philosophy. This 5×5 cluster pays slot launched in July 2017 and quickly became a player favourite, combining Japanese anime aesthetics with sophisticated cascading features and a progressive multiplier system that keeps sessions dynamic. The game’s defining characteristic is its Princess Trinity bonus meter system, charged by winning combinations to unlock free spins with multiple difficulty options. For players seeking high volatility gameplay with genuine skill expression in bonus selection, Moon Princess delivers on both fronts.
Base Game & Features
Moon Princess operates on a fixed 5×5 grid system using cluster pays mechanics rather than traditional paylines. This means you win by matching three or more identical symbols horizontally or vertically anywhere on the grid. There’s no scatter symbol to trigger bonuses—instead, the game uses a unique meter-charging system where every winning combination pushes you closer to the Princess Trinity bonus round.
The Girl Power Features
Three distinct princess characters activate randomly during base gameplay, each bringing their own mechanical twist:
- Princess Love: Transforms symbols to create additional winning combinations, providing immediate win generation on the same spin.
- Princess Star: Adds wild symbols to the grid in random positions, expanding win potential across multiple directions.
- Princess Storm: Zaps away existing symbols to make room for new cascades, often triggering chain reactions when combined with other features.
When the Princess Trinity meter charges to full capacity—achieved through accumulated wins during the base game—all three princess powers combine in a special re-spin featuring their combined magical abilities. This moment often marks the transition into the bonus round or delivers immediate substantial wins in the base game itself.
Symbol Drops & the Cascading Multiplier
Moon Princess uses a sophisticated cascading symbol mechanic that builds momentum across extended win sequences. After each winning combination, the middle symbol of that combo transforms into a Moon Wild and remains locked in place. A progressive multiplier then increases with each successive cascade, climbing from 1x up to a maximum of 20x the base value. Critically, this multiplier does not reset between spins—it carries forward through the entire session, including into bonus rounds. Grid clears award 100x the corresponding multiplier value, creating explosive pay moments when you clear all 25 symbols.
Bonus Features & Free Spins
The bonus trigger mechanism in Moon Princess sets it apart from conventional slots. Rather than landing scatter symbols, you must clear the entire 5×5 grid during regular play to unlock the Princess Trinity bonus selection screen. This mechanic demands sustained winning combinations, making the bonus feature a genuine achievement rather than a chance occurrence.
Free Spins Selection & Variants
Once bonus is triggered, players choose between three princess-themed free spins modes, each with distinct mechanics:
- Love Free Spins: Grants 4 free spins with a recharge mechanic—clearing the grid again during free spins adds additional spins without cap.
- Star Free Spins: Provides 5 fixed free spins with standard cascading and multiplier mechanics active throughout.
- Storm Free Spins: Awards 8 free spins, offering the longest bonus session of the three options.
The game permits up to 20 total free spins through retriggering. Critically, the multiplier accumulated during base gameplay carries into bonus rounds entirely intact, meaning if you’ve built a 15x multiplier in the base game and trigger a long free spins sequence, you’re starting from a substantial multiplier advantage. This mechanic creates the potential for epic chain reactions that define many high-win Moon Princess sessions.
Bonus Buy Feature
Players in jurisdictions where permitted can purchase direct entry into the bonus round rather than waiting for the grid-clearing trigger. This feature is available at most casinos offering Moon Princess, though some regions restrict or prohibit bonus buy mechanics due to regulatory requirements. When available, the bonus buy option appears as the most frequently used mechanic in streaming content, as content creators can control when bonus rounds commence rather than waiting for organic triggers.
Our Honest Verdict
Moon Princess represents a pivotal moment in cascading symbol game design, and it remains one of Play N’ Go’s most recognisable releases. The game’s framework—combining the Girl Power modifiers, Princess Trinity meter charging, and progressive multiplier system—creates a compelling feedback loop where players consistently feel progression toward bonus unlocks. The 5000x maximum win potential pairs legitimately with the 10/10 volatility rating, making this a game built specifically for high-variance chasers comfortable with extended droughts between significant wins.
The standout strength lies in feature variety. Between the three Girl Power options, the meter-charging mechanic, and the multiplier system, no two sessions feel identical. The anime aesthetic—vibrant pastel tones blended with the princess character design—resonates strongly with players who appreciate visual personality in their slots. Gameplay velocity is consistently high, with cascades and feature triggers maintaining engagement across longer sessions.
The honest limitation: bonus triggers require grid clears, and the Princess Trinity meter sometimes resists charging quickly during unlucky sequences. Players report sessions where the feature “tries to stop you from getting the bonus instead of helping you reach it,” creating frustration during extended base game play. The grid-clearing mechanic, whilst innovative, means you cannot trigger free spins through scatter symbols alone—you must generate wins organically. This positioning Moon Princess firmly in the “high stakes” category where patience becomes as critical as fortune.
Moon Princess suits high-volatility specialists, anime aesthetic enthusiasts, and players seeking feature-rich gameplay with genuine strategic choice in bonus selection. Those preferring frequent smaller wins or simpler trigger mechanics should look elsewhere. With 96.50% RTP and sophisticated mathematical backing, the game offers legitimate value for its intended audience. It remains a benchmark release nearly eight years after launch, proving that well-executed mechanics and distinctive visual design create enduring appeal.
