Moon Princess 100 app

What changed in Moon Princess 100

This sequel is the follow-up to Moon Princess, released by Play'n GO on 7 April 2022. The number in the name is the headline change: the free spins count and the win multiplier, both capped at 20 in the original, can now climb to 100. Everything else is recognisably the same game, with Love, Star and Storm still helping out when a spin goes nowhere.

The trade-off is clear from the figures: a higher ceiling and a slightly lower top RTP. The sequel is built to concentrate more of its return into rarer, larger events, which makes it a harsher game for small budgets.

Playing Moon Princess 100 on a phone screen

You will not find a standalone download for this game. You reach it through a casino app from the App Store or Google Play, where it opens as an HTML5 game in the app’s game window. Hold the phone upright and the square grid fills most of the width; the multiplier display and princess characters sit around it, with stake and spin controls at the bottom within easy reach of your thumb.

Landscape gives you a little more room for the artwork but pushes the controls to the side. On a 6-inch or larger screen either works. On a compact handset, portrait tends to keep the gems a readable size. If you are not sure which suits you, our portrait vs landscape guide explains how slots adapt to orientation.

• Turn on Low Power Mode or battery saver for long sessions; the cascade animations use the graphics chip heavily.
• Mute the game from its own settings menu rather than the phone’s volume rocker if you want other sounds to keep working.
• Keep notifications for the casino app limited to account messages so a pop-up does not cover the spin button; see casino app notifications.

How to start Moon Princess 100 in a casino app

1. Log in to your casino app and tap the search bar in the casino or slots lobby.
2. Type Moon Princess 100 and pick the tile marked with the 100; the original appears in the same results, so check the name.
3. Once the grid loads, open the menu and read the rules page, including the RTP line near the bottom.
4. Choose a stake with the coin or stake selector. UK caps of £5, or £2 for 18–24s, are applied automatically.
5. Tap Spin and let the drops finish. Each spin, cascades included, lasts at least 2.5 seconds under UK rules.
6. Set a reality check reminder in the app’s safer gambling menu if you have not done so already.

Girl Power, Trinity and the clear-the-grid prize

Wins work as before: line up three or more identical symbols in a row or column and they pay, vanish and let new symbols fall. On a spin that produces no win at all, one of the princesses may use her Girl Power at random.

Clearing every symbol off the grid pays 50 times your total bet in the base game. The Trinity feature lets all three princesses act in turn, and clearing the grid during Trinity is what starts free spins. That two-step route is the main difference from the original, where a clear grid on any spin was enough.

Moon Princess 100 free spins and the 100x multiplier

When free spins begin, you choose one of the three princesses. Your choice sets both how many spins you get and which Girl Power is active through the round. If you choose to keep Girl Power on, it plays on every spin that does not win, rather than at random. The multiplier rises with wins during the feature and can reach 100.

The choice is a trade between more spins with a gentler power or fewer spins with a stronger one. Play'n GO publishes the effect of each princess but not which choice returns more, so no right answer exists to look up. Picking the same princess every time just makes the round more predictable to watch.

Feature buy is not available to players in Great Britain, so the only way into free spins on Moon Princess 100 is through normal play. Our bonus buy entry explains the rule.

Moon Princess 100 RTP, volatility and what they cost

The top published RTP is 96.2%. Over a very long run, £100 staked would on average return about £96.20, a theoretical cost of about £3.80. The phrase ‘top version’ matters here: Play'n GO offers casinos lower settings, and the rules page in your app is the only place that shows which one you are playing. Our guide to finding a slot’s RTP in an app walks you to it.

With high volatility, the spread of results is wide. Picture a £20 budget at 20p a spin: 100 spins is plenty for the cascades to look busy, but with a game of this type it is quite possible to see the whole £20 go without a single large result. Plan for that outcome rather than hoping to avoid it.

These numbers are averages, not forecasts. Real sessions can lose far more or occasionally win; the point is that the cost of play grows with stake and speed. Setting a budget first, as shown in our phone budgeting guide, keeps that cost under control.

The 15,000× maximum win

The top published payout is 15,000 times the stake, three times the original’s 5,000x. At 10p, that cap is £1,500; at £2 it is £30,000; at £5 it is £75,000. Reaching it needs a combination of high multipliers and long cascades in free spins, and very few players will ever see it. Large wins also trigger extra checks at UK casinos, as covered in large wins on casino apps.

UK rules for Moon Princess 100 in apps

Every UK-licensed app applies the same Gambling Commission rules to this game. Autoplay is absent, and so is the turbo button. Spins last at least 2.5 seconds. Your balance and the running net position for the session stay visible. Wins smaller than your stake cannot be dressed up with celebration effects. Stakes are capped at £5, or £2 for players aged 18–24, as explained in our UK slot design rules guide.

The free demo version can only be opened after the casino has verified your age, and some apps choose not to offer demos at all.

Moon Princess 100 vs similar slots

If the original felt too slow to pay anything worthwhile, the sequel will not fix that; it shifts even more weight to the feature. Reactoonz 2 offers a similar Play'n GO style on a bigger grid. Starlight Princess shares the anime look but pays for eight or more matching symbols anywhere on screen. Our cluster pays slots page lists more grid games.
