Moon Princess Origins: Slot Overview

Moon Princess Origins is a 5x5 cluster-pay slot from Play'n GO, built around clearing symbols off the grid. Wins land when 3 to 5 matching symbols connect horizontally or vertically, and winning symbols are removed so the rest drop down. The twist is that no new symbols fall in from above, so every spin feels like a little board-clearing puzzle.

I found the setup pretty easy to get into, especially if you've played the older Moon Princess games. It has high volatility, up to 96.29% RTP on the best version, stakes from 0.10 to 100, and a max win of 20,000x. Fair enough on paper, though the anime theme and overall presentation feel a bit too close to what we've already seen.

Moon Princess Origins Features

Girl Powers are the main hook here. Princess symbol wins can trigger them, with a 50% chance for a 3-symbol win, 75% for 4, and 100% for 5. Love converts one set of symbols into another, Star adds 1 or 2 Wilds, and Storm removes 2 symbol sets. If the same Princess wins twice, her next trigger chance goes up to 100% until it fires or the round ends.

Heart, Star, and Circle wins also feed the empowerment side of things. Get more than 5 of the same low symbol and the matching Princess gets stronger. Love can convert 2 or 3 sets, Star can add 2, 3, or 4 Wilds, and Storm can clear 2 or 3 sets. That part is proper handy because the base game can drag a bit until one of these powers kicks in.

Moon Princess Origins Slot Information

5 reels and 5 rows give you a neat little grid, and the symbol values are straightforward enough. Heart, Star, and Circle are the low pays, worth up to 2.5x for a 5-symbol cluster. Love, Star, and Storm are the premium Princess symbols, paying up to 10x for five, while mixed Princess combinations pay up to 5x.

Wilds are a big part of the flow. They appear in the middle of winning low-symbol clusters, substitute for pay symbols, and five Wilds pay 20x. I like that touch because it makes the low symbols more useful than they first look, and it gives the slot a decent rhythm once the screen starts opening up.

Moon Princess Origins Slot Features

Trinity starts when a 6-part charge meter is filled by wins that include all 3 Princess symbols, with Wilds counting as Princesses too. A 3-symbol win fills 3 parts, a 4-symbol win fills 4, and a 5-symbol win fills 5. Once the meter is full and no more wins happen, you get 1 respin and the powers go off in order, Love, Storm, then Star.

10 free spins arrive if you clear the whole grid during that Trinity respin, apart from Wilds. During free spins, another full clear gives you instant prize orbs instead of the usual reward. Love's orb pays 5x to 150x, Star's pays 75x to 1,000x, and Storm's pays 1,000x to 10,000x. You can add more spins by filling the meter again, up to 20 total.

💬 What Players Say
Reviews say the mechanics are still good fun, especially if you like clearing the grid and building towards Trinity. The main complaint is that the look feels too familiar and the 20,000x top prize seems more theoretical than likely. Based on 5 reviews.
Ryan Cole’s Verdict

Our Verdict

Overall, I think Moon Princess Origins is decent if you fancy a relaxed session with a bit of build-up and the odd proper moment when the grid nearly clears. The mechanics are the best part. Trinity, the upgraded Girl Powers, and those orb prizes give it enough to keep me interested, even when the base game goes a little quiet.

Still, I'm not entirely sold on the presentation. It looks fine, mate, but not much more than that, and the whole Origins angle doesn't add loads. So yes, I'd say it's worth a go, especially for Moon Princess fans, but I wouldn't call it the strongest one of the lot.

Moon Princess Origins FAQ
How do the Girl Powers trigger in Moon Princess Origins?
They trigger from Princess symbol wins. A 3-symbol win has a 50% chance, a 4-symbol win has 75%, and a 5-symbol win guarantees it.
What does each Princess power actually do?
Love converts one set of symbols into another, Star adds 1 or 2 Wilds, and Storm removes 2 symbol sets from the grid. When empowered, those effects get stronger.
How do I trigger the Trinity feature?
You need to fill a 6-part meter with wins that include all 3 Princess symbols. Once it's full and the current spin stops producing wins, you get 1 respin with all 3 powers firing in sequence.
How are free spins triggered in this slot?
You trigger free spins by clearing the entire grid during the Trinity respin, apart from any Wilds left behind. That awards 10 free spins straight away.

Clearing the grid during free spins awards a Princess orb. Love pays 5x to 150x, Star pays 75x to 1,000x, and Storm pays 1,000x to 10,000x.
