Defenders of Mystica

by Yggdrasil

In a land far, far away, there was a beautiful castle on top of a mountain. And in that castle lived a family of fairies/elves/pointy-eared folk who had a bit of luck on the National Lottery. But they didn’t blow all of their winnings on sparkly trinkets and amazingly, there’s still 10,000x stashed under the mattress that you could walk away with in Defenders of Mystica. Mystery symbols and free spins are going to be your best friends as you set about ransacking this fairy-tale dwelling.

Defenders of Mystica Features

Defenders of Mystica is certainly trying its best to make it easy to land a win with its 28,125 ways. Wins can come in groups of 3, 4, 5, 6 or 7 symbols and the great thing is that they can form a win from the first reel on the left and make their way across to the right or from the last reel on the right, making their way to the left.

There are 5 low-paying symbols and these are represented by 10 through Ace, and then there are 5 picture symbols with the most valuable being 2.5x for a group of seven redhead ladies. As you can see, it might be easier to snag a win but the payouts are fairly low. In order to boost your balance, you are going to need mystery symbols.

Mystery Symbols & Free Spins

Mystery symbols land and will reveal themselves to be one of the regular paying symbols. This can help form a large group and hopefully give you some better payouts. If the Mystery symbols do create a winning combo, then they stick in place while all others are removed and a respin will occur. This continues to happen all the while these Mystery symbols are forming part of a win. 

On the first and last reel, Scatter symbols may fall and this triggers 7 free spins. Any mystery symbols that land during the triggering spin will also become an additional free spin as they convert into Scatter symbols

If you don't want to wait around for scatter symbols, then you may have the option of paying 100x to trigger the 7 free spins. This will only be possible in some areas outside the UK.

These symbols reveal themselves to be any of the regular paying symbols and could create a win. If they do so, then you get to enjoy an Avalanche Respin.

Avalanche Respins

Mystery symbols being part of a winning group makes the rest of the symbols disappear and only winning ones stay put. The reels respin and the Mystery symbols try again—this sequence keeps on going until the Mystery symbols don’t form a win.

Free Spins

A Scatter on the first and last reels will get you 7 free spins. Any Mystery symbols that land during the triggering spin will also turn into Scatters and grant more spins. Any Mystery symbols forming part of a win during the round will remain on the reels.

Defenders of Mystica Review

I can't remember the last time I played a slot that relied so heavily on Mystery symbols! It can be a little restrictive but when they land as frequently as they do in Defenders of Mystica, you should be in for an exciting ride.


It is an impressive-looking castle that appears to be guarding all of the magical secrets in Defenders of Mystica. There are some beautiful waterfalls to the front and also mountains in the background. It is literally a fairytale setting. You can't imagine anything bad happening here apart from say, some lucky slot player running away with the fairy’s treasure. As you move into the Free Spins Bonus, nighttime falls but the setting doesn't really change. It's a nice enough look and feel that carries over onto mobile screens too.


Those Mystery symbols really are everywhere you look and that is just as well as they are the only way you are going to start seeing your bankroll move in the right direction. As these symbols create part of a winning group you can see a run of respins that can last for quite some time and this is where the real magic happens. It can occur in both the base game and during the Free Spins bonus.

Win Potential

If these mystical creatures deem it so, you could walk away with 10,000x as the maximum prize. As I have said before, you're unlikely to get anywhere near this with regular paying symbols so just hope and pray the Mystery symbols turn up frequently. The volatility is very high and the RTP sits at 96%.

My Verdict

I'm not usually a fan of slots that depend so specifically on one element to produce any action or decent payouts. That said, when they land frequently, it is possible that the restrictions float out the castle window and some decent payouts can occur. This is exactly my experience of Defenders of Mystica and I hope the same goes for you.
