Moon Princess by Play'n GO is one of those grid slots that just sticks with you. After spending way too many hours chasing those bonus triggers, I can say it really does deserve its reputation as a standout video slot.
This one’s got a 5x5 cluster pays grid, cascading reels, and a personality-packed set of features. Every spin feels unpredictable, especially if you love slots that actually have some depth and character.
Released back in July 2017, Moon Princess features three princesses with their own quirks and powers. The Girl Power random features, the Princess Trinity meter, and the fact that you get to pick your free spins style—these things combine for a grid slot that’s way more layered than most from that era.
Play'n GO built their name on high-volatility, feature-rich slots with killer visuals. Moon Princess is a textbook example. The Sailor Moon vibes hit you right away, and each princess—Love, Star, and Storm—brings her own mechanic to keep things lively between bonuses.
I honestly expected this slot to feel dated after so many years. But it doesn’t. The mechanics are still sharp, the 5,000x max win is nothing to sneeze at, and the 96.5% RTP is still very competitive.
That RTP makes this a solid pick if you care about value. Always check the paytable before you start spinning, though—some casinos tweak the RTP, and you want the best shot possible.
Key Takeaways
-
Moon Princess runs on a 5x5 cluster pays grid with cascading wins, plus a handful of bonus features that can pop up anytime.
-
The free spins round lets you choose your favorite princess, and each one changes the gameplay and win potential in a real way.
-
This is a high volatility slot, so dry spells can drag on, but if you’re patient, that 5,000x ceiling is worth chasing.
Quick Verdict And Key Facts
Moon Princess is one of those slots that just refuses to fade away. The visuals still pop, and the anime theme hasn’t lost its charm after all these years.
It plays beautifully on mobile, too. You don’t lose any of that crisp animation or detail, even on a smaller screen. The 96.5% RTP is a major plus in my book.
Bonus mechanics here are more intricate than most high-volatility slots of its time. It’s still a go-to for fans of the genre—myself included.
Slotcatalog shows Moon Princess as a top performer for Play’n GO, with tons of players still coming back. The game’s got staying power, and that’s not just nostalgia talking.
Bigwinboard has logged some wild wins on this slot—those free spins can really surprise you. It’s not just theory; players have seen those big payouts land.

The different RTP options actually matter. Some casinos set the game to a lower RTP, so always check the rules page before you dive in. Play’n GO lets casinos pick, and you want the best version if you’re playing for real money.
That max win of 5,000x is right up there with the best of them. You’ll need a wild bonus round with multipliers stacking up, but I’ve seen it happen—those cascades can really snowball.

You need three or more matching symbols touching horizontally or vertically to score a win. Sometimes a symbol ends up in two clusters at once, which is always satisfying. There are no paylines here—cluster pays is a different beast from the usual reels.
Demo Mode And Autoplay
Most casinos let you play Moon Princess in demo mode—great for testing the waters before risking real cash. Autoplay is available, with options for spin count and stop conditions. Not all sites handle it the same, so double-check before you start a marathon session.
How The Game Plays
How To Play Moon Princess
Alright, let's talk Moon Princess. If you're new to this one, the first thing you'll notice is the 5x5 grid—no classic reels, just a grid that fills with symbols every spin. It's a lively, energetic setup that makes every round feel like anything could happen.
Here's the deal: you win when three or more matching symbols connect in a line, either horizontally or vertically. Once you hit a win, those symbols vanish, and everything above drops down—classic cascade action, and it's honestly one of the most satisfying mechanics around.
Cascades can chain together, so a single spin can set off a flurry of wins. That's where the game really comes alive, especially when you see the grid start to clear out and that anticipation builds.
Instead of spinning reels, the symbols drop in with a static animation. It's a little different, but it keeps things moving fast. Your main goal in the base game? Clear enough symbols to fill the Princess Trinity meter and set yourself up for those juicy free spins.
Symbols, Paytable, And Winning Clusters
Let’s break down the symbols, since knowing what to look for is half the fun. You’ve got low-pays and high-pays, and trust me, you’ll know when you hit the premium stuff.
Low-pay symbols:
-
Stars
-
Hearts
-
Bells
-
Green crescent circle
High-pay symbols:
-
Love Princess (red)
-
Star Princess (blue)
-
Storm Princess (yellow/green)
-
Full Moon Wild
The three princesses are your big hitters, and landing a 5-of-a-kind cluster with any of them? That's when you really feel the rush. The Full Moon Wild symbol steps in for any other symbol, so it’s your best friend for making those clusters connect.
Cascades, Wild Retention, And Drop Multiplier
Every time you hit a win and trigger a cascade, the game drops a Wild right in the center of the winning cluster. That Wild can help set off even more wins as the round continues.
With each new cascade in a single spin, your win multiplier climbs by 1x—up to 20x if you can keep the chain going. The multiplier resets if you don’t land a win, so the pressure’s always on to keep the action flowing.
If you manage a long cascade chain, that multiplier can really start to stack up. Hit four cascades in a row, and you’ll be looking at a 4x multiplier on that last win. In the base game, the multiplier resets after every spin, but if you get into the free spins, it sticks around and keeps building—this is where things get exciting.
Bonus Features And Bonus Potential
Girl Power Feature
Here’s where Moon Princess really stands out: the Girl Power feature. Sometimes, when you don’t land a win, the game throws you a lifeline and triggers a special ability, depending on which princess is active.
It’s a welcome surprise, especially on those spins that look dead at first. These features help keep the momentum going and can turn a cold spin into something worth celebrating.
|
Princess |
Girl Power Ability |
|---|---|
|
Love (Red) |
Transforms one symbol type into another to create or extend a winning cluster |
|
Star (Blue) |
Places up to two Wild symbols on the grid to complete winning combinations |
|
Storm (Yellow/Green) |
Removes a set of symbols from the grid entirely, opening space for new drops |
Honestly, Girl Power is a lifesaver. You never quite know when it’ll show up, but when it does, it can completely change the flow of the game.
Princess Trinity Meter And Trinity Trigger
Keep an eye on the Trinity meter over on the left. It fills up as you land princess symbol clusters, and the bigger the cluster, the more the meter fills:
-
3-of-a-kind princess cluster: fills 1 section
-
4-of-a-kind princess cluster: fills 2 sections
-
5-of-a-kind princess cluster: fills 3 sections (fills the meter entirely on its own)
Once the meter's full, you trigger the Princess Trinity feature. This is where all three princesses unleash their abilities in sequence—no extra bet required, just pure bonus action. It’s a mini bonus game that can set you up for some great wins.
The Trinity feature is also your ticket to the free spins round. If you fill the meter during free spins, instead of starting a new round, it just extends the feature—so you get more chances at those big hits.

The multiplier in free spins is where the magic happens. It doesn’t reset between spins, so if you get a strong cascade chain near the end of the bonus, you could see some seriously big wins—up to 5,000x your bet if the stars align.
Choosing your princess for free spins is more than just picking your favorite color. Storm gives you fewer spins, but her grid-clearing power can open up the board for big cascades. Star’s double-win modifier is perfect if you’re hitting a lot of medium clusters. Love’s Wilds are a lifesaver when you’re just one or two symbols away from a full grid clear.

How It Compares With Gemix And Moon Princess Christmas Kingdom
Gemix is probably the closest cousin—same 5x5 grid, cluster pays, and those random character features that can really shake things up. The theme’s crystal and gem-based, so it feels different, but the core mechanic is right at home for anyone who loves Moon Princess.
Moon Princess Christmas Kingdom is basically the original game in holiday clothes. If you’re already a fan, it’s a fun seasonal swap with the same mechanics, so you won’t have to relearn anything. The math model stays the same, which is a relief for those of us who like consistency.
Bankroll Fit, Risk Profile, And Session Expectations
Let’s get honest about volatility—Moon Princess is high variance. If you’re used to classic slots, this one can eat your balance fast if you’re not careful, especially while you wait for that Trinity meter to fill or for a lucky grid clear.
I always recommend starting with a session bankroll of at least 50 to 100 times your bet. So, if you’re spinning at $0.20 a pop, you’ll want $10 to $20 to really give yourself a shot. Betting more? Make sure you scale your budget up accordingly. Anything less, and you might not even see a bonus round before your session ends.
The free spins round is where the real fireworks happen. Sometimes, you’ll get a short, uneventful bonus, but if you hit those big multipliers and a nice cascade chain, that’s when you see why people chase the 5,000x win. It's not every day, but when it happens, man, it's unforgettable.
Pros, Cons, And Final Take
What The Slot Does Well
|
Strength |
Why It Matters |
|---|---|
|
96.50% default RTP |
This slot starts you off with a 96.5% RTP, which is already better than what you’ll find in most games. That edge might sound small, but trust me, it really adds up over hundreds or thousands of spins. |
|
Three distinct free spins modes |
You get to pick between Love, Star, and Storm for your free spins. It’s not just a visual thing—each choice actually changes the way the bonus plays out, so you get real control over your session. |
|
Persistent drop multiplier in free spins (up to 20x) |
The multiplier doesn’t reset between free spins. It keeps building, and that’s where those jaw-dropping wins can come from if the reels line up just right. |
|
Girl Power activates on losing spins |
Dead spins? Not always a dead end here. The Girl Power feature randomly kicks in after a losing spin, shaking up the grid and sometimes saving your streak. |
Where It Falls Short
|
Weakness |
Why It Matters |
|---|---|
|
Multiple lower RTP configurations available to casinos |
Some casinos set the RTP as low as 84.5%, and you won’t always know which version you’re playing. It’s a bit of a gamble before you even spin. |
|
Bonus trigger requires clearing the full 5x5 grid |
You’ve got to clear every single symbol on the grid to trigger the bonus. It’s a tough ask, and you’ll definitely feel the anticipation (and sometimes frustration) as you chase it. |
|
No bonus buy option |
If you’re the type who likes to shortcut straight to free spins, you’re out of luck. You’ll have to earn your way in the old-fashioned way—by grinding those reels. |
|
Hit frequency not publicly disclosed |
There’s no clear info on how often you’ll actually land a win in the base game. That makes it tricky to set your expectations or pace your bankroll. |
Overall Recommendation
Moon Princess has earned its place as a Play'n GO classic, and honestly, it’s easy to see why if you love a slot with depth. The grid mechanics, that trio of free spins choices, and the persistent multiplier make for sessions that can swing from icy to electric in a heartbeat.
If you’re into anime vibes, character-driven features, and the thrill of cluster pays, this game’s a treat. But if you want quick-fire bonuses or steady, frequent wins, you might find yourself waiting a bit too long for the action to heat up.
Playing with a welcome bonus? Always check those wagering requirements first—Moon Princess can chew through your balance fast on a cold streak but can also deliver a massive win when the stars align. Some promos don’t count grid slots toward wagering, and occasionally, casinos block bonus play here, so double-check before you dive in.
