Moon Princess 100 Review

Moon Princess 100 is a 5x5 grid slot from Play’n Go built around Cluster Pays, not paylines. You need 3 or more matching symbols connected horizontally or vertically to get paid. I see it as a feature-heavy remake with a better visual package than the original, but the princess theme is still niche and not everyone will buy into it.

Volatility is high, max win is 15,000x, and bets run from 0.20 to 100. RTP is listed at 96.20% in most reviews, though one source gives 96.57%. For serious players, the important part is simple, this game can swing hard and the base game can drag a bit, so I would not touch it without a proper bankroll.

Moon Princess 100 Slot Features

Winning symbols disappear from the grid and new ones fall into place, so cascades are a core part of the game. Each winning combo adds an extra Moon Wild, and the global win multiplier climbs after every combo up to 100x. That is where the real upside sits. Without chain potential, this slot would be far less interesting.

Random Girl Power can trigger on dead spins. Star adds bonus wilds, Storm removes symbols, and Love transforms symbols. Princess wins charge the Power Meter, and filling three sections triggers Princess Trinity, a single spin with all three effects active. Clear the whole grid outside that feature and you get the Clear Grid Bonus for 50x stake.

Clear the grid during Princess Trinity and you unlock Free Spins. You choose Love, Star, or Storm Free Spins, and that choice determines the modifier active in the round. More spins can be added by filling the Power Meter, up to 100 total. A Bonus Buy is mentioned in one review, but no price is given, so I cannot call the buy value one way or the other.

Bonus Buy Options

Bonus Buy Girl Power
Girl Power
A random feature on non-winning spins that applies one of three effects: bonus wilds from Star, symbol removals from Storm, or symbol transformations from Love.
Bonus Buy Princess Trinity
Princess Trinity
Triggered by filling three sections of the Power Meter with princess wins, this grants a single spin with all three special effects active and aims to clear the entire grid.
Bonus Buy Clear Grid Bonus

Bonus Buy Bonus Buy
Bonus Buy
A bonus buy option exists in some versions and jurisdictions, letting players purchase the bonus feature directly instead of spinning into it.

Symbols and Paytable

7 pay symbols are mentioned. The low pays are moons, stars, hearts, and bells. The premiums are the three princesses, and those matter most because they also feed the Power Meter. A row of 5 princess symbols pays 16x, while a mixed five-symbol combo of the princesses pays 8x. That is fair, but not massive by itself.

Moon Wild is the only special symbol named in the reviews. It substitutes for other symbols and has its own pay values, though exact wild payouts are not listed. Since this is a cluster-style setup with extra wild creation and multipliers, raw paytable value is not the point. The slot lives or dies on feature chaining.

RTP, Volatility and Win Potential

96.20% RTP and high volatility is a workable mix, but I would not overrate the ceiling. 15,000x is solid, not elite. For bonus hunters chasing truly huge caps, the ceiling is too low for this variance. You can still get paid well here, but it is not in the top bracket for max-win hunters.

Bet limits are broad enough for casuals and high stakes sessions, with a cited range of 0.20 to 100. One source also lists a 10 max bet, but the more detailed reviews point to 100, and that fits the high roller positioning better. Dead-spin frequency is masked a little by random Girl Power, though long cold patches are still part of the profile.

💬 What Players Say
Reviews are broadly positive on the feature depth, visuals and 15,000x top end. Criticism centres on the niche princess theme, sharp volatility and a max win that serious hunters may find only decent rather than top-tier. Based on 3 reviews.
Ryan Cole’s Verdict

Review Summary

Overall, Moon Princess 100 has enough going on to keep me interested. The cascades, extra wilds, 100x multiplier, random modifiers and choice-based Free Spins give it more depth than most 5x5 grid slots. It is clearly built for players who can handle swings and wait for the right sequence.

My verdict is blunt. For serious players, this is playable with a proper bankroll, but I would not call it a top-tier bonus hunting target. The feature set is strong, yet the 15,000x ceiling is only decent against the volatility. If you like the mechanics, fine. If your whole game is chasing monster caps, I think the ceiling is too low for this variance.

It uses Cluster Pays. You need 3 or more matching symbols connected horizontally or vertically on the 5x5 grid.

The game has a global win multiplier that increases after each winning combo. It can build all the way to 100x during a chain, which is the main driver of big hits.

A Bonus Buy option is mentioned in one review, but no price is provided. Without the cost, I cannot judge the EV properly, so I would not make claims on value.
