Moon Princess Christmas Kingdom Slot Overview

Moon Princess Christmas Kingdom is a holiday-themed grid slot from Play'n GO, built on a 5x5 Cluster Pays layout with Cascading Reels. Wins form when three or more matching symbols line up horizontally or vertically, after which winning symbols are removed and remaining ones drop down. Three anime-inspired princesses sit beside the reels and hurl modifiers onto the board at key moments.

Mechanically, the game mirrors Play'n GO's earlier release Sisters of the Sun, sharing the same math model, feature set, and 15,000x max win. What separates this version is its Christmas skin and one new addition called What the Fox. Default RTP sits at 96.20%, volatility is rated high at 8 out of 10, and stakes run from 0.20 to 100 per spin. Mobile compatibility is full across all devices.

Symbols and Paytable

Seven pay symbols populate the grid. Four lower-value Christmas decorations (a ball, star, heart, and bell) return between 2x and 3x the bet for a five-symbol line. Three princess symbols in green, blue, and red sit at the top of the table, each paying 10x the bet for five of a kind. A mixed combination of any princesses pays 5x.

Wilds appear only after a win. When a three-symbol winning combination is removed, a golden moon wild drops into the vacant middle position. It substitutes for all pay symbols but not the fox scatter. Compared to the studio's previous work on the original Moon Princess, the symbol hierarchy here is largely unchanged, just wrapped in festive artwork.

Bonus Features Breakdown

Every spin marks five random grid positions with mistletoe. Any win landing on a mistletoe spot increases the win multiplier by +1. During the base game this multiplier resets each spin, but in free spins it carries over. The design choice to double the mistletoe count to 10 during the bonus round makes the multiplier climb noticeably faster.

On any non-winning spin, a Girl Power modifier may trigger depending on which princess is active. Love converts one symbol type into another. Star adds one or two wilds. Storm removes two sets of symbols entirely. These fire in a fixed rotation, so you always know which is next.

Landing one fox scatter activates the Trinity Feature, resetting the multiplier and granting one free game round. If cascades produce no win, each princess uses her power in sequence: Love first, then Star, then Storm. Clear every symbol from the grid during Trinity to unlock Free Spins. Players then choose Love (4 spins, +4 retrigger), Star (5 spins, +3 retrigger), or Storm (8 spins, +2 retrigger), with a hard cap of 150 total spins.

What the Fox

RTP, Volatility and Max Win

Default RTP is 96.20%, though operators can select lower configurations, so checking before you play is sensible. Volatility rates 8 out of 10 on Play'n GO's own scale. Maximum win caps at 15,000x the bet, a threefold jump over the original Moon Princess, though the probability of hitting it sits around 1 in 1 billion according to published figures. Not everyone will be comfortable with those odds, but the feature chain from Trinity into Free Spins with a persistent multiplier is where the realistic big-win path lies.

💬 What Players Say
User rating of 8.7/10 from a small sample. Players appreciate the feature depth but note the game is very similar to Sisters of the Sun. Based on 3 reviews.
Ryan Cole’s Verdict

Verdict

Moon Princess Christmas Kingdom is, frankly, a Christmas-themed clone of Sisters of the Sun with the original Moon Princess characters swapped back in. I am not entirely sold on the level of novelty here; the maths, volatility, and nearly every feature are identical. Still, the What the Fox mechanic is a welcome tweak, giving players a random second chance at a scatter and making the route to Trinity slightly less punishing.

For anyone who enjoys grid-based cluster slots with layered modifier systems, this plays well. The persistent free spins multiplier and the choice of three bonus modes offer real strategic flavour. Seasonal slot fans looking for something beyond a basic reskin will find enough personality in the princesses and their powers to keep sessions engaging, even if the underlying engine is familiar ground.

Moon Princess Christmas Kingdom FAQ
How does the What the Fox mechanic work in Moon Princess Christmas Kingdom?
After a spin ends, the What the Fox feature may randomly place a fox scatter symbol anywhere on the grid. This gives an extra chance to trigger the Trinity Feature without needing the scatter to land naturally on the initial spin.
What are the differences between the three Free Spins options?
Love awards 4 free spins with +4 per retrigger scatter, Star gives 5 spins with +3 per scatter, and Storm provides 8 spins with +2 per scatter. Each option activates its corresponding Girl Power modifier on every non-winning spin.
Does the win multiplier reset during the Free Spins round?
No. The multiplier carries over from the Trinity Feature and does not reset between free spins. Additionally, the number of mistletoe positions doubles from 5 to 10, making the multiplier climb faster.
How do you actually reach the Free Spins in this slot?
You must first trigger the Trinity Feature via a fox scatter, then clear every symbol from the 5x5 grid during that round. Clearing the grid outside Trinity awards a flat 50x bet prize instead of free spins.
How does Moon Princess Christmas Kingdom differ from the original Moon Princess?
The grid expanded from the original's format to a 5x5 Cluster Pays system, the max win tripled to 15,000x, and the bonus structure shifted to require a full grid clear through the Trinity Feature. Mechanically it mirrors Sisters of the Sun rather than the first Moon Princess.
