Moon Princess is an action-packed online slot designed by Play’n GO that plays on a grid with five rows and five columns. It is visually reminiscent of the Sailor Moon anime television series that relate the adventures of several schoolgirls who can transform into powerful superheroes.
The manga-themed slot introduces players to a trio of lovely princesses, each of whom has a unique power that helps players win more on the 5×5 grid. The game is equipped with a round of free spins that activates whenever you clear all symbols from the unconventional reel grid.

Moon Princess Theme
Moon Princess is loosely based on the popular Sailor Moon anime series and was released just in time for the show’s twenty-fifth anniversary in July 2017. The game combines elements of the shoujo and shounen visual styles in manga comics. It features three princesses (Love, Storm, and Star) with distinctive hairstyles, costumes, and superpowers.
All three are impeccably designed in line with the cutesy art style of the manga genre. The upbeat synth-pop soundtrack further improves the overall feel of the game. With that said, we are confident Moon Princess is likely to appeal to most reel spinners even if they are not part of the manga fandom.
How Moon Princess Compares to Other Slot Games
Moon Princess achieved such massive success that Play’n GO decided to follow it up by releasing a festive sequel, aptly titled Moon Princess: Christmas Kingdom. The festive edition uses a similar cascading mechanic but has a significantly higher winning potential, with a maximum payout of up to 15,000 times the bet. The most you can win in the original version of the game is three times lower at 5,000 times your total stake.

Moon Princess Symbols and Payouts
Moon Princess plays on a 5×5 grid and uses the cascading reels mechanic instead of conventional paylines. Players form winning combinations by matching three or more identical symbols in a row, vertically or horizontally. The matching symbols are then removed from the grid and the remaining icons drop down in their places, potentially creating several wins in succession.
The symbol in the middle of the winning combination turns into a wild moon that boosts your chances of winning more on the next drop. The multiplier in the upper left corner of the screen increases with each winning drop up, to a maximum of 20 times the win, and resets after a losing round. The wild moon is the top payer in this slot with a maximum payout of 50 times the total stake, followed by the three princesses.

Bonus Features Overview
Moon Princess has several special features of interest, starting with the moon wilds and progressive multipliers that increase up to a maximum of 20 times the win. There is also the Girl Power feature where each of the three princesses helps players with different modifiers. Love, Star, and Storm combine their superpowers during the Princess Trinity feature. The cherry on top of the cake is the round of free spins.
Wild and Scatter Symbols
The wild symbol in this game is shaped like a moon and appears in place of the middle icon in each matching combination. The wild improves your chances of landing winning combos on the next drop since it can substitute for all other icons in the game, including Love, Star, and Storm. Moon Princess has no scatter symbols. Players activate the round of free spins by clearing all icons from the grid.
Girl Power Feature
The Girl Power feature activates randomly after losing rounds. The active princess during the feature appears on the right side of the grid and changes after each consecutive win. All three princesses have unique powers that help players create more winning combinations.
- Princess Love randomly transforms one set of icons into different symbols
- Princess Star can add up to two extra wild moons on the grid.
Princess Storm clears two sets of icons from the grid.
Princess Trinity Feature
A golden meter sits on the left side of the grid and players must fill all three sections to unlock the Princess Trinity feature. Only winning combinations created with the princess icons contribute to filling the meter. Love, Star, and Storm then unite their superpowers and take turns helping players collect larger cash prizes. The feature is impossible to retrigger.
Free Spins with Multipliers
To trigger the free spins round with progressive multipliers, you must clear all twenty-five symbols from the grid by landing consecutive winning combinations. Then you can choose from the three options listed below. Keep in mind that a round with fewer spins involves greater risk but has a higher winning potential.
- Princess Love awards 4 free spins, with the option to retrigger another 4 bonus rounds.
- Princess Star offers 5 free spins and can possibly retrigger 3 more rounds at no cost
- Princess Storm awards 8 free spins, with the option to retrigger 2 extra rounds at no cost.
Another great thing about this feature is that the progressive multiplier does not reset after losing rounds. It can continue growing until it reaches the 20x maximum. Players who succeed in recharging the golden meter to the left of the grid are rewarded with additional free spins. Those who are lucky enough to clear the entire grid during the feature are in for a tasty cash prize of 100 times their stake.

Moon Princess FAQs
Is there an autoplay feature in Moon Princess?
Moon Princess comes with an autoplay feature that allows you to go through up to a hundred rounds without interruption. The feature can deactivate after a win or when you trigger the free spins round. Click on the smaller orange button next to the green spin button to turn it on.
Is it hard to trigger the free spins round?
We regret to say the free spins are extremely difficult to trigger, largely due to the high volatility of the game. However, the round can prove to be very lucrative so the wait is well worth it. The Princess Trinity feature is, unfortunately, deactivated during free spins.
How can I be sure the outcomes are fully random in Moon Princess?
All games developed by Play’n GO, including Moon Princess, are fully certified for fairness and integrity. The software studio has obtained certificates for randomness from several accredited testing agencies, including Gaming Laboratories International (GLI), Quinel, and BMM Testlabs.
