Moon Princess by Plan n Go


Moon Princess is a game that divides opinion in many circles, though all agree that it’s one of the toughest nuts to crack and an extremely high–volatility title. If you score some wins you’ll probably think it’s one of your favourite Play n Go slots, but if you get caught in a dry spell it can feel like the tightest game around!

This slot is based on a 5 reel and 20 payline format with a 5×5 grid of symbols. With each ‘spin’ new symbols drop from the top of the screen. Winning lines are formed horizontally and vertically of three or more identical symbols. Those in a winning line disappear to be replaced by others with the chance of creating more wins.

With each win your prize multiplier increases by one, up to a maxium of 20x. It’s a simple variation on the tumbling reels set up.

The real objective is to clear the whole screen of symbols because this triggers the bonus round and sets you up for as many as 20 free spins. You can imagine how good that can be if you are on 20x multiplier!

Our advice is to take it easy with this slot – don’t charge in with high stakes because you’ll get burned easily. Start off with 20p a spin max. And of course you can try for free right here before you play with your own money.

Moon Princess is available on mobile, desktop and tablet and you can play at any of our recommended slot sites.




This video slot was actually built to celebrate the 25th anniversary of the manga cartoon, Sailor Moon, which was a hit in the 1990s. The graphics are pretty smart as you would expect.

The lower value symbols are mystical looking items, whilst the higher value ones are the three princesses themselves – Love, Star and Storm – which each pay out at 10x your stake for 5 in a row. The Wild symbol is the moon and it pays out at 50x for 5 in a row, as well as substituting for all others symbols.

The win sequence is like this: when you match three or more symbols horizontally or vertically, then the matching symbols are removed and those above drop down in their place.

ALSO – the middle symbol in the win line becomes a Wild moon, AND your multiplier increases by one. This happens up to 20x!


These are the key features of the game:

Girl Power Feature: this can happen at any time randomly during the base game when there is a non-winning spin. Whichever princess is active on the right of the screen when this happens will affect the symbols on display as follows:

Love Princess – 1 set of symbols is chosen to transform into another set.

Star Princess – 1 or 2 Wilds get added into the 5×5 grid.

Storm Princess – 2 sets of symbols are removed from the grid.

Princess Trinity Feature: Every winning line that features a Princess adds to the meter on the side of the screen. When it fills completely you get 1 extra free spin.

Free Spins Feature: This is activated when the whole grid is cleared. Remember, with each winning combination, more symbols are removed from the grid. It takes time, but eventually you’ll hit a blank screen!

Then the fun starts.

There are 3 options to choose from – Love Princess is four Free Spins, Star Princess is five Free Spins, Storm Princess is eight Free Spins.

The relevant Princess’ Girl Power feature is also active for every non-winning spin during the bonus round, and of course you still get the multipliers of up to 20x with consecutive wins.

Furthermore, charge the on-screen meter and get additional free spins (4 for Love Princess, 3 for Star Princess and 2 for Storm Princess). You can add another 20 free spins this way, and also get a 100x prize if you clear the board again during the bonus round!


There is a lot going on in Moon Princess, that’s for sure. It’s a really hard game to win big on and one of the most volatile around. However, it can still be a lot of fun, and once you’re in the free spins round, the payouts can be huge. If you like volatile slots of course you can also try classics like Raging Rhino.
