About This Slot
It’s only November but we are already sitting knee deep in festive slots to review. The best so far has been the excellent Santa’s Stack game from Relax Gaming, but Play n Go are taking the battle to their rivals with this re-work of their fun Moon Princess game, ready to play at any of the new slot sites in 2021. It’s very common for developers to take an existing format and give it a Christmas facelift without adding any new features – why invest hugely in a slot that will only be played for a few weeks of the year after all? But in this case Play n Go have at least added some extra features so fans of the original title won’t just feel like their playing the same game but in their party hat! Play n Go fans who look closely might also notice that this game feels similar to their Sisters of the Sun slot.
In terms of the theme, as you would expect, Moon Princess Christmas Kingdom offers a snowy scene as a backdrop with a castle, holly and fir trees to ramp up the Christmas vibe. It’s all very cute and slightly retro.
Meanwhile, the game action takes place 5×5 grid that is covered in Christmas decorations with a fairy princess hovering to the side of the reels. The Cluster Pays mechanic means you need to match symbols in Clusters instead of on paylines and comes with the classic cascades feature. And whilst you won’t find Santa anywhere, there is a definite seasonal atmosphere with a pleasant, magical feel.

RTP, Variance and Top Payout
The RTP of this slot is variable, giving a maximum of 96.2%, which is just about above average for an online slot. The volatility level is high (8/10 according to Play n Go) which means you can expect extreme highs and lows and an uneven distribution of wins. So, if you want a relaxing play with regular pay outs, look elsewhere! You can find out more about this in our slots variance guide.
There is a 20p minimum bet which is reasonable and a recommended starting point as you get to grips with the gameplay. Remember, at this variance you can burn through your balance very fast! For the luckiest gamers, a 15,000x stake top payout awaits, which is possible if you manage to hit the right combination of Multipliers and Modifiers during the Free Spins feature.
Symbols and Graphics
The symbols in Moon Princess Christmas Kingdom include 3 fairy princesses and 4 Christmas decorations. The princesses are called Love, Star and Storm, while the decorations include the blue star, the red heart, the green bauble and the gold bell.
The decorations can pay up to 3x stake for 5 of a kind. The fairy princesses can pay out 10x stake for 5 exact matches or 5x stake for 5 mixed fairies.
There is also a moon symbol which is the Wild for the game and this can award up to 30x stake for 5 of a kind. This Wild also substitutes for the other symbols in the game to create more potential wins. Finally, the fox Scatter is required to activate the Free Spins round.

Gameplay and Features
Play n Go have ramped up the features here so that there is a little more going on than in the original slot and event trigger regularly enough to keep things interesting despite the high variance.
Mistletoe Multipliers
On every spin, 5 random positions are marked with mistletoe. If you hit a win that includes a symbol on a mistletoe position, the Multiplier increases by 1.
Trinity Bonus
Landing a fox Scatter will trigger a Free Spin. The What the Fox mechanic can also add a random Scatter to the screen to help trigger the feature. The Trinity Bonus resets the Multiplier and if a win doesn’t occur, the Girl Power feature begins with all 3 fairy princesses awarding their feature. Matching all symbols on the screen also triggers the Free Spins round.
Girl Power Bonus
On any non-winning spin, the Girl Power feature can trigger at random.
Whichever fairy princess is hovering on the screen at that moment will determine the feature for the round. The Love princess will transform a series of symbols, the Star princess will add 1 or 2 Wilds to the screen, while the Storm princess will remove 2 sets of symbols from the screen, causing another cascade and more potential winning combinations.
Free Spins
When the Free Spins round is triggered, you can choose one of the 3 fairy princesses to receive 4, 5 or 8 Free Spins initially – the 3 rounds are called Love, Star or Storm.
The free spins rounds come with enhanced features to increase the chances of hitting bigger wins. Mistletoe Multipliers increase from 5 to 10 and the Girl Power feature triggers on EVERY non-winning spin, rather than at random. Landing a Scatter symbol will also award 2, 3 or 4 extra Free Spins with a maximum of 150 Free Spins available.
Our Verdict
For those who follow these things closely, Moon Princess Christmas Kingdom is styled on Play n Go’s Moon Princess slot but it does in fact use the game mechanics of Sisters of the Sun. So, you’ll see that the features are copied exactly from the latter, with the exception of the What the Fox feature. This may feel a bit lazy but in truth its common practice in Xmas slots and there is enough originality here to separate this game from the two that inspired it.
What we like is that Christmas Kingdoms does have a truly magical feel and a great atmosphere and the graphics are of a high quality as you would expect. As far as maths go, the top payout of 15,000x stake remains the same as the originals and is a tempting reward. You’ll need to trigger the bonus features and hit some Multipliers to be anywhere even close to hitting the top payout. Like most high variance games, the action is cranked up considerably in the bonus round – and with more Mistletoe spots and Girl Power on all non-winning spins, things become more interesting for sure.
Just remember, this is a high-risk spinner though, so be prepared for ups and downs as you cascade towards the festive rewards!
