Moon Princess 100 Demo & review

Moon Princess 100 is Play'n GO's 2022 rework of Moon Princess: the same 5x5 grid where three in a row or column pay and drop away, with a far higher ceiling on the win multiplier. The price is a narrower road to free spins, which now need a full Trinity meter and then a cleared grid in the same round. It suits players who will spin a long time for one very large round, not those who want the bonus to come round often.

How Moon Princess 100 works

Three or more matching symbols in a straight line, across or down, pay, and every row and column counts, so one symbol can sit in two wins at once. Winning symbols are removed, the rest drop, and each new drop raises the win multiplier on the wheel above the win list. Between spins in the base game, that wheel shows x1.

The reels never deal a wild. One is created in the middle position whenever a three-symbol win is removed, and it stands in for every symbol. Once only wilds are left on the grid, they are removed as well, which is how a grid can empty completely.

When a spin brings no win, the princess beside the grid can step in at random. Love turns one set of symbols into another, Star adds one or two wilds, and Storm removes two sets of symbols. The first princess is random, and after each power the turn passes on in the fixed order Love, Star, Storm.

The paytable pages were not part of our capture, so there is no table here. The win lists in our session put three of the green medallion at 10 cents and three of a princess at 30 cents before the multiplier, which tells you how much of this game's value sits in the chain rather than the symbol.

The base game before spin 1 at $1: the 5x5 grid, the multiplier wheel at x1 above the win list, and the empty Trinity meter below it. FluxPlays demo test, 1 November 2026.

Which Moon Princess version is this?

Play'n GO has built several games on the original's grid. This one changes two things against the 2017 game: the way into free spins and how far the multiplier can go.

How to trigger free spins in Moon Princess 100

Free spins take two steps inside one paid spin: fill the Trinity meter, then empty the grid during the free round it awards. How the parts connect:

1. Wins made of princess symbols fill the three-section meter: a line of five fills all three sections, four fill two and three fill one. Wilds can be part of those wins.
2. A full meter, once no wins are left, awards one free round with all three Girl Powers.
3. An empty grid in that round starts Free Spins and pays no prize of its own.
4. An empty grid at any other time pays the instant grid-clear prize.

Free Spins carry the game. Everything in the base game either feeds the meter or keeps a dead spin alive.

The Trinity free round

The multiplier is reset as the round begins. Every drop that brings no win gets the next Girl Power, Love first, Star second and Storm third, until all three have acted. When it ends, the princess who was beside the grid before Trinity returns.

Free Spins: pick a princess

Before the first spin you choose Love for 4 spins, Star for 5 or Storm for 8. The multiplier carries over from the Trinity round, does not reset until the feature is over, and can climb to x100. Your princess acts on every spin without a win, Trinity cannot start, and filling the meter adds 4, 3 or 2 spins, up to 100 in all.

The grid-clear prize

Emptying the grid outside the Trinity round pays an instant 50x the total bet, multiplied by the win multiplier at that moment. By the rules, a clear with the wheel at x10 is worth 500x the bet. A clear in the base game is therefore a big round in itself, even though it does not lead to Free Spins.

RTP, volatility and max win

Neither the help text nor Play'n GO's game page states an RTP, a volatility label or a maximum win. Review sites agree on 96.2% as the top RTP and on high volatility, and they quote 15,000x as the top win, a figure the game does not state, so the table leaves the max win out. Casinos choose the RTP version, and nothing in the practice build tells you which one it carries.

Our Moon Princess 100 demo test

Two long cascades made our session. On spin 32 the wheel climbed to x5. Along the way five princess symbols in a line paid $15.00 at x3, and the round finished at $29.85.

Base spin 32 of 100 at $1, settled: the wheel at x5, five princess symbols paying 15.00 at x3 on the list, 29.85 for the spin. FluxPlays demo test, 1 November 2026.

Spin 81 went further, to x10, and paid $24.70. The wins on its list late in the chain were three-symbol ones worth 10 to 30 cents before the multiplier. Between them the two rounds made up 58% of what the session paid back, and most other wins were small: 25 of the 40 paid under $1.

Spin 81 of 100 at $1: the wheel at x10, with three-symbol wins at x7 to x9 on the list. The spin paid 24.70 in all. FluxPlays demo test, 1 November 2026.

The Trinity meter never filled, so the free round, Free Spins and the grid-clear prize appear here as the rules describe them. Treat these figures as one session's play, not a measure of the RTP.

Is it worth playing?

For a max-win hunter with patience, yes. For a player who wants the bonus to come round in an ordinary session, no. The higher ceiling only matters in Free Spins, and Free Spins need a full meter and an empty grid in the same paid spin, so most of your time goes on base cascades. Those still have a top end of their own: a long chain lifts every later win, and a cleared grid pays a multiplied instant prize.

For us the Trinity free round is the moment to watch, since three Girl Powers in a row are the best chance the game gives you to empty the board.

Pick Moon Princess if you want free spins from any cleared grid and can live with a lower ceiling. Pick Moon Princess 100 if the bigger ceiling is the point and you accept a narrower door to it.

In the demo, watch the meter under the win list rather than the balance. A single line of five princesses fills it at once, and that is the only way into the free round.

The board after spin 100 at $1 with no win: the wheel at x1, an empty meter and a different princess beside the grid than at the start. FluxPlays demo test, 1 November 2026.
