Max Win: 5,000 x stake per spin

The Moon Princess slot is played on a 5×5 grid and has 5 reels and 20 paylines technically. Winning combinations are created by landing 3, 4 or 5 matching symbols in a row, either horizontally or vertically.

You can join this powerful princess trio from 20p to £100 per spin. The stakes are clearly displayed at the bottom of the screen and can be changed by clicking on the appropriate stake button. Scroll left or right for lower or higher stake amounts.

There’s an Autoplay function where between 10 and 100 autospins can be chosen. You can stop autoplay on any win and if the free spins are activated. There are options to add single win, balance decrease or increase limits too. Finally, there’s a lightning bolt which gives you turbo spin mode.

The Moon Princess RTP is 96.5% which is above the slots average and higher than the customary 96.2% RTP for most Play ‘n GO slots. Extremely high variance, this is rated as 10/10 by Play ‘n GO on the volatility front. The max win is 5,000 x your total stake per spin.

Theme – harness girl power

Theme: Manga

High Value Symbol: All 3 Princesses

Compatibility: Mobile, Tablet, Desktop


The Moon Princess slot game has a Japanese manga theme and is based on a powerful princess trio: Love, Star and Storm. The game is loosely based on the Sailor Moon TV series which celebrated its 25th anniversary when the slot was originally released in 2017.

With a purple background, this Japanese inspired game has an assortment of mystical items and 3 princesses (Love, Star and Storm) as symbols. The 3 princesses pay the most giving you 0.3, 1 or 10 x your total stake for 3, 4 or 5 in combination.

The Moon is the wild and substitutes for all other symbols. The most rewarding symbol in the game, it will pay 1, 3 or 50 x your total stake for 3, 4 or 5 across a payline.

moon-princess-slot-wild-symbolWild Substitutes for all symbols + pays up to 50x

It’s important to note here that 3 princesses anywhere on a payline will pay 0.2, 0.5 or 5 x your total stake for 3, 4 or 5 in combination. Although there is no scatter, you must simply clear the grid to trigger the Free Spins feature.

Moon Princess Mobile


You can play Moon Princess on desktop, mobile and tablet devices. The 5×5 grid and simple graphics work well on smartphone devices.

Moon Princess Bonus Features

Moon Princess comes with 4 bonus features. With a symbol drop mechanic, successive wins lead to Moon wilds and an increasing multiplier up to 20x. Then you have the Girl Power feature where each of the princesses offer different modifiers. All combining in the Princess Trinity feature, the main attraction is the free spins where you choose 1 princess and their modifier to be active during the feature. You can also benefit from multipliers up to 20x.

Symbol Drop feature

When you land a winning combination, the Symbol Drop feature comes into play. The contributing symbols are removed with the remaining symbols dropping down in the empty spaces. This gives you the chance to form new wins.

More importantly, the middle symbol of a winning combo transforms into a Moon wild and the multiplier increases with each win/drop, up to 20x.

Girl Power feature


Then you have the Girl Power feature which is triggered randomly on a non-winning spin. Depending on which active princess is display on the right-hand side of the gird, a different and unique ability is performed. They help you form winning combos basically:

  • Love Princess: 1 set of symbols is chosen which then transform into another symbol
  • Star Princess: 1 or 2 wilds will be added to the grid
  • Storm Princess: 2 sets of symbols are destroyed and removed from the grid

Princess Trinity feature

Landing winning combinations with princess symbols only ((involving the wild if needed) will fill up the meter to the left of the grid. When you fill the on-screen meter completely, you will activate the Princess Trinity feature.

Now, the Love, Star and Storm Girl Power features take turns in triggering to give you more wins. When you cannot form any more wins, a Girl Power feature is performed until no more wins are possible. This continues until all Girl Power features are performed.

Free Spins feature


If you do manage to clear the whole grid of symbols, you will activate the Free Spins feature. You then get to choose from 1 of 3 options:

  • Love Princess: 4 free spins
  • Star Princess: 5 free spins
  • Storm Princess: 8 free spins

The chosen Princess’ Girl Power feature is then active for the duration of the feature as it triggers on every non-winning free spin. If you get continuous wins, you could get a multiplier up to 20x.

If you fully charge the on-screen meter, you will get additional free spins (4 for Love, 3 for Star and 2 for Storm). You can do this multiple times with a maximum of 20 free spins on offer in total. Furthermore, if you manage to clear the grid, you’ll also receive a prize of 100 times your stake.

Moon Princess Review Summary – all about the multipliers

Bonus Features

RTP (96.5%)

Max Win (5,000 x)


The Moon Princess slot is actually more straight forward than it reads. Successive wins will lead to the multiplier increasing up to 20x in the base game and free spins.

With big wins achievable in the base game and bonus features, the key to big payouts is the multiplier which can increase with each drop. I found the Storm Princess modifier the most rewarding as it destroys 2 sets of symbols which allows for more new symbols to be added. Just for reference, it has exactly the same gameplay as Rise of Olympus which has a Greek mythology theme.

A cult favourite, it’s all about successive wins to achieve the big payouts. If you like increasing multipliers, most Megaways slots provide this in their free spins features.

Play ‘n GO has since released Moon Princess Christmas Kingdom. Played on a 5x grid with Cluster Pays, it offers similar features but 3 times the win potential (15,000 x stake).

  • 5,000 x max win
