Moon Princess Christmas Kingdom: Slot Overview

If you’ve never seen Who Do You Think You Are, it’s a show where a different celebrity each episode digs into their family history. As the title suggests, it can be fascinating to discover who that person is connected to. Of course, everyday people have equally compelling family trees, since everyone is linked to all kinds of colourful figures from the past. That same idea of lineage can crop up in the slot scene too, sometimes in interesting ways. In this case, the trail begins with Play’n GO’s iconic Moon Princess, branches out into Sisters of the Sun, and then loops back with Moon Princess Christmas Kingdom.

In real terms, Moon Princess Christmas Kingdom blends the Sailor Moon-style vibe of Moon Princess with the gameplay mechanics, features, and stats found in Sisters of the Sun. The result is a 5×5 cluster-paying grid slot, packed with features that boost both payouts and excitement. All three titles share a similar look, though this one clearly leans harder into Christmas. To set the festive tone, Play’n GO covers the scene in snow, castles, pine trees, and—naturally—three women hovering beside the reels, ready to drop modifiers onto the grid at key moments. There are more overtly festive slots out there, but the point stands: Moon Princess Christmas Kingdom delivers a distinctively flavoured Xmas spin.

From a stats perspective, Moon Princess Christmas Kingdom doesn’t differ from Sisters of the Sun. Both come with variable RTP settings, a default of 96.2%, and a highly volatile model rated 8 out of 10. The theoretical upside is far stronger than what the original Moon Princess offered, although landing the top outcome has odds of roughly 1 in 100 million. For anyone wanting an anime-inspired holiday session, it runs on any device, with stakes from 20 p/c to $/€100.

Wins land when three or more identical symbols connect in a line horizontally or vertically, starting from any position on the grid. Those winning symbols are then removed, allowing the remaining icons to fall and potentially form additional wins. Whenever a winning three-symbol cluster is cleared, a wild symbol is dropped into the empty middle spot. Wilds can substitute for any pay symbol, and there are seven in total. From low to high value, you’ll see four Christmas decorations and three princesses. The princesses pay 10x the bet for a five-symbol match, or 5x the bet for a five mixed princess combination.

Moon Princess Christmas Kingdom: Slot Features

Moon Princess Christmas Kingdom is loaded with features—essentially the same set of extras seen in Sisters of the Sun, with one fresh addition called ‘What, the Fox’.

Win Multiplier

Every spin, 5 random grid positions are highlighted with mistletoe. If a win lands on a mistletoe spot, the win multiplier increases by +1. In the base game, the multiplier resets between spins, while in free spins it carries over.

Girl Power

Randomly, on any non-winning spin, the Girl Power feature can activate. There are three versions, and which modifier you get depends on the princess currently hovering on screen. They are:

• Love – changes a group of symbols into a different symbol type.
• Star – drops 1 or 2 wild symbols onto the grid.
• Storm – clears 2 groups of symbols from the game panel.

Trinity Feature

This feature triggers when a single fox scatter symbol lands, awarding 1 free game round. Scatters can appear on the initial spin or through the What, the Fox mechanic, where a scatter is randomly added anywhere after the spin finishes.

Once Trinity is activated, the win multiplier resets, and if a symbol drop fails to create a win, a Girl Power modifier is triggered until all three have had a turn. The key point is that clearing the grid of symbols during the Trinity Feature triggers free spins. On top of that, if the grid is cleared during a normal spin, the prize for doing so is 50x the bet.

Free Spins

When triggered, players may choose one of three free spins options – Love, Star or Storm Free Spins, which award 4, 5, or 8 initial spins, respectively. In free spins, the number of mistletoe locations increases from 5 to 10, and the chosen Girl Power modifier triggers on every non-winning spin. Note that Trinity can’t be triggered from here, though free spins can be retriggered. When a single scatter symbol lands, 4, 3, or 2 free spins are added for the Love, Star, or Storm bonus round, respectively. The maximum total is 150 free spins.

Moon Princess Christmas Kingdom: Slot Verdict

Play’n GO has taken players on a slightly unusual route to arrive here. Moon Princess evolved into Sisters of the Sun, and that framework was then reused while bringing back the Moon Princess styling to create this Christmas version. As Christmas slots go, Moon Princess Christmas Kingdom isn’t the most classic interpretation, but it still has plenty of charm—mostly thanks to its leading ladies—and it certainly helps that the feature set is pretty darn tootin too.

Even those who didn’t play the original Moon Princess have likely heard how enjoyable it is. It was bursting with character and features like a stocking stuffed with little surprises, and the payouts were respectable as well. Sisters of the Sun built on that base by raising the potential and adjusting the features to push the risk/reward balance. A big part of that was making free spins only reachable through the Sisterhood feature—called Trinity here. With that setup, if a scatter didn’t land on the initial spin, you already knew the bonus round wasn’t happening. Moon Princess Christmas Kingdom improves the outlook by adding a small chance via the ‘What, the Fox’ mechanic. Of course, ‘What, the Fox’ won’t show up often, but having it there makes things feel less final. Beyond that and the visuals, practically everything else remains identical to Sisters of the Sun, including the maximum win of 15,000x the bet.

As with many Christmas reskins, Moon Princess Christmas Kingdom likely didn’t require a massive build effort. Still, the additions are appreciated, and it plays just as smoothly as any other Moon Princess or Moon Princess-style slot—so it’s hard to find many reasons not to load it up if you’re after some Christmas-themed grid slot action.
