Moon Princess 100 Slot RTP, Details & Wager Limits

Reels/Paylines: 5 reels + 20 paylines

Stakes Range: 20p to £100 per spin

RTP: 96.2%

Max Win: 15,000 x stake per spin

The Moon Princess 100 slot game is played using 5 reels, 5 row, and 20 fixed paylines. Winning combinations are formed with 3 or more matching symbols in a row, horizontally or vertically. Once a win is removed from the reels, the remaining symbols above it will drop down, with the win multiplier increasing for each drop.

Stakes range from 20p up to £100 per spin. To adjust your total bet, simply select one of the values below the reels. You can view the higher and lower values by selecting the hearts with the + and – icons in them. Autospins and Hyperspins are possible in most territories too apart from the UK.

The Moon Princess 100 RTP is 96.2%, which is bang on average for a Play’n GO slot. But please bear in mind that the variance here is high, so big wins won’t land as often as, say, a slot with low or medium volatility.

The maximum win is 15,000 x your stake, which is 3 times as much as the original Moon Princess slot, which was 5,000 x. Your best chance of landing this will be in the Free Spins feature where you could get up to 100 free spins along with numerous multipliers up to 100x too.

Theme – Audio & Design Features – which princess will cause havoc on the reels?

Theme: Japanese Manga

High Value Symbol: 3 Princesses

Compatibility: Mobile, Tablet, Desktop


Based loosely on the Sailor Moon TV series from 1992 in Japan, the Moon Princess 100 slot has a Japanese Manga theme, which has proven to be very popular since the original game was released back in July 2017.

Princesses Love, Star and Storm are at the heart of the action, appearing to the right of the reels and patiently waiting for their symbols to land before coming to life and causing chaos on the reels.

In terms of audio, the soundtrack is quite bland, and you’d be forgiven for muting the game while you play. But ignoring the music, the sound effects are what makes the game really. It’s all very intense when the princesses spring into action and winning combinations are blasted off the reels.

On the reels, you’ll come across a green charm, a star, a heart, and a bell as the lower value symbols. Storm, Star, and the Love princess symbols are the higher paying ones, with all 3 princesses the most rewarding as they payout exactly the same – 0.3, 1 or 10 x your stake for 3, 4 or 5 in combination.

The game’s wild is a moon, which substitutes for all symbols and pays up to 50x.

Moon Princess 100 Bonus Features

The Moon Princess 100 slot comes with 3 main bonus features. You’ve got 3 Girl Power modifiers, a trinity feature, and an exciting free spins feature where large wins are very much possible. Let’s expand on all 3 for you.

Girl Power feature

This feature can be triggered randomly whenever a spin is completed without a winner landing. The princesses rotate to the right of the reels, so whichever one it is when the feature gets triggered will perform her respective power to help create a win.

Love Converts 1 set of symbols into another symbol
Star Gists 1 or 2 wilds onto the reels
Storm Removes 2 sets of symbols from the reels

During the Free Spins feature, the chosen power triggers on every single spin where there’s no winner.

Trinity feature

To the left of the reels, you’ll notice a power meter. If you land wins with 3, 4 or 5 princess symbols, it will fill up to 3 sections of the meter.

When 3 sections have been filled, you’ll be awarded 1 free spin known as Princess Trinity. Multipliers are reset, then each princess will use their modifier on all non-winning spins until all 3 have been used, thus potentially leading to some big wins.

If you manage to clear the grid during this feature, you’ll trigger the Free Spins feature.

Free Spins feature


If you manage to clear the grid in the base game, not only will you initially be awarded 50 x your total bet, you’ll also trigger the Free Spins feature.

You will get the chance to pick a princess for the feature, and they each come with different perks:

  • Storm = 8 free spins
  • Star = 5 free spins
  • Love = 4 free spins

As mentioned when the feature appears, fewer spins mean higher risk, but higher potential.

If you manage to fill the power meter during the Free Spins feature, you will get extra spins. How many you get will depend on who you’ve chosen for the feature. Love will get you 4 extra, Star gives you 3 extra, and you will receive 2 extra with Storm. You can continue to fill the meter until you hit 100 free spins in total.

A nice benefit to note here is that the multiplier is never reset during this feature and can grow up to a maximum of 100x, which is a lot higher than the original game where it only went up to 20x.

RTP (96.2%)

Max Win (15,000 x)


There’s no doubt that this Moon Princess 100 slot is better than the original. The first release was a hit, so this one will no doubt follow suit. With 100x multipliers and up to 100 free spins up for grabs, there’s potential to win big here. The maximum win of 15,000 x your stake is also a massive improvement on the original.

While the soundtrack leaves a lot to be desired, the sound effects more than make up for it and add excitement to the game. Overall, it won’t be everyone’s cup of tea, but if you loved the original then you’ll enjoy this one.

If you’re a fan of increasing multipliers, check out the best Megaways slots on the market. Many of these have this feature during their Free Spins rounds, and some of the max wins are huge. Take the Wheel of Fortune Megaways slot for example – 1 million ways to win and massive max win potential of 80,150 x your stake.

  • 15,000 x stake max wins
  • 100x multipliers
  • Up to 100 free spins
  • Highly volatile
  • Nothing too different from the original
