Few slots have earned a cult following quite like Moon Princess. Released by Play’n GO in 2017, this anime-inspired title broke the mold of conventional fruit machines and went on to spawn an entire series of sequels — a testament to just how captivating the original remains to this day.
Moon Princess Slot Theme & Design
Moon Princess takes players on a trip to outer space across three equally enchanting backgrounds that shift depending on which princess is controlling the reels — dreamy purple shades, midnight blues, and glowing emerald greens all make an appearance. The soundtrack and sound effects carry the energy of an adventure slot, encouraging you along the way.
How It Works
Moon Princess is an anime-inspired online video slot powered by Play’n GO. It features a 5×5 grid with no traditional paylines. Instead, it matches symbols horizontally or vertically in groups of three or more to generate winning combinations — a Cluster Pays mechanic that keeps every spin dynamic.
Symbols
Low-pay symbols include four mystical icons — a green-yellow moon charm, a blue star, a red heart, and a winged bell — each awarding up to 3x your bet for a five-of-a-kind. The three princesses (Storm, Star, and Love) are the high-pay symbols, each worth 10x for a cluster of five. The Moon wild substitutes for all other symbols and pays 50x your bet for a cluster of five.
Key Features
On any non-winning spin, the Girl Power feature may trigger at random depending on which princess is standing beside the grid. Love transforms one set of symbols into another type, Star adds one or two extra wild Moon symbols, and Storm removes two sets of symbols from the grid entirely.
When the power meter to the left of the screen is filled, it triggers the Princess Trinity feature. Should the grid be fully cleared, players win an instant 100x their total bet. Clearing the grid also unlocks the main Free Spins feature, where players choose their princess — Love grants 4 free spins, Star gives 5, and Storm awards 8.
A win multiplier increases by ×1 after each cascading drop of winning symbols. It resets at the end of a spin sequence but is carried over into the free spins round, where it can climb up to a maximum of ×20 and stays active throughout the entire bonus.
RTP, Volatility & Max Win in Moon Princess Slot
Moon Princess is a high-volatility slot with an RTP of 96.50%. The max win sits at 5,000x your stake, meaning a $100 bet could return up to $500,000. Bets range from $0.10 to $100 per spin. ACH Casinos Given the high volatility, a bankroll of at least 200x your bet size is recommended to handle the swings comfortably — and trying the free demo first is a smart way to get a feel for how the cascading wins build before playing for real money.
Mobile
Moon Princess runs flawlessly on iOS and Android devices using HTML5 technology, our casino making it just as enjoyable on a phone or tablet as on desktop.
Verdict
Moon Princess is a masterclass in grid-slot design — visually stunning, mechanically rich, and with enough bonus layers to keep experienced players engaged for hours. The high volatility means patience is required, but when the grid clears and free spins fire, the rewards can be spectacular.
