Moon Princess

Moon Princess is a Play’n GO slot released in July 2019, introducing the magical-girl trio, Love, Star, and Storm, that the entire series still revolves around. The game runs on a 5-reel, 5-row cluster grid where 3 or more matching symbols connected horizontally or vertically pay and cascade away to let new symbols drop in. The theoretical RTP is 96.50%, volatility is high, and the win cap is 5,000x the bet.

A Wild forms whenever 3 identical symbols connect in a cluster, substituting for every other symbol, and pays 50x the bet for a full 5-symbol Wild connection. If a cascade leaves nothing but Wilds on the grid, they clear away, which can help set up the game’s free spins trigger.

Girl Power

The Girl Power feature can trigger randomly on any non-winning spin. One of the three princesses is active at a time, and her power fires automatically: Love transforms one set of symbols into another, Star adds up to 2 Wilds to the grid, and Storm destroys two sets of any symbol outright. The active princess changes after each trigger, and the game round continues normally once her effect resolves.

Free Spins

Clearing the entire grid triggers Free Spins, and players choose one of three starting options: Love for 4 spins, Star for 5, or Storm for 8, fewer spins carrying higher risk but a higher ceiling. Whichever princess is chosen stays active for the whole round, triggering her power on every non-winning spin, and the win multiplier does not reset between spins, climbing as high as 20x by the time the round ends. Fully charging the meter again mid-round adds extra spins, though the Girl Power feature itself does not run outside this dedicated round.

Moon Princess Review

Moon Princess earned its long-running sequel line by keeping its central idea simple: three distinct powers, one active at a time, doing exactly what their name promises rather than layering extra conditions on top. Choosing a starting princess before free spins begin gives players a real say in how a round unfolds, since picking Storm’s 8 spins over Love’s leaner 4 is a genuine risk decision rather than a cosmetic choice, and the multiplier’s slow climb toward 20x rewards a round that keeps finding wins rather than paying out everything at once. The 5,000x cap looks modest against what later entries in the Moon Princess series would eventually offer, but the clean three-power structure this original established is still the version every spin-off measures itself against, whether by keeping the same three princesses or replacing them with a different cast entirely. Part of that staying power comes from how legible the whole system is on a first session: the Wild forming directly out of a 3-symbol connection ties the grid’s two main mechanics together in a way a player can see happening rather than having to read about, and the Girl Power feature firing on non-winning spins specifically means the game keeps finding something to do even on a quiet stretch of the reels, rather than leaving those spins feeling entirely wasted.
