How to play Finn And The Swirly Spin mobile slot

NetEnt add a little magic to this Finn and The Swirly Spin slot by changing all the rules.

This Finn and the Swirly Spin slot game is the first of it’s kind, as you’ll see that unlike other 5×5 grid slots (like the equally good Emoji Planet game) the symbols don’t fall from above.

Instead the slowly rotate from the bottom left hand corner to the centre of the reels, creating wins whenever 3 or more symbols are on a horizontal or vertical line.

Are the Swirly Spins just a gimmick?

We thought so at first, but we have to admit that there was something wonderfully different about watching the symbols spin around: like watching a roulette wheel, hoping for the little white ball to land on your number.

It’s exciting, especially as the little white ball is actually a key that starts at the bottom left hand corner, and with each win where the symbols explode and disappear, slowly gets closer and closer to the centre.

This Finn and the Swirly Spin slot free spin bonuses

There are 4 free spin bonuses you unlock in this Swirly Spin Finn video slot, which like in much loved casino games like Immortal Romance or even the Castle Builders II slot.

You unlock by getting one of those keys. Every time you trigger the free spins, you collect more and more keys, unlocking more of the bars than Finn frequent in the Free Spins world.

Because Ireland and Bars go hand in hand.

Take your time with this casino game

Finn and the Swirly Spin slot is not a big hit game. Instead, what you have here is a little bit of an Emerald Isle Leprechaun slot adventure.

Your budget will last you remarkably long, and whilst you get 30x to 50x your bet wins in the free spins bonus game, you can get the exact same features randomly in the base game.

Meaning that your budget stays steady as you try and drink your way to as many free spin bars as possible.

Like any good pub crawl, you might not always remember why you are here, but you’re having so much fun, you don’t really care.

Bonus Features

Avalanche Swirly Spin Mechanics: There are 25 spaces on the board and they start from the bottom left hand corner, going round on themselves, until the final space which is at the centre of this 5x5 grid slot.

The symbols load in that order, and when you get a win, those symbols will disappear, and more symbols will load up from the left hand corner, moving around the snake like pattern.

It's like a cascading win in Pixies of the Forest, except the symbols go around a coil, instead of dropping down from above.

Wild Symbol Generation: You get wins when three or more of the same symbols find themselves either vertically on horizontally on the same line.

Once a win is made, a wild symbol (a star) will be created in it's place when the symbols disappear, and more load from the bottom of reel 1.

When the wild symbol is used, not only will it give you a win and cash, but it will also explode and take with it every adjacent symbol.

Random Features: There are a total of 4 random features you can get after any spin, given to you by our helpful Leprechaun friend in this Finn and the Swirly Spins mobile slot.

  • Irish Luck: One of the horizontal or vertical lines will be transforms to all of the same symbols, giving you a win, and an avalanche.
  • Starfall Wild: Places 2 to 5 extra wilds anywhere on the reels.
  • Dragon Destroy: Destroy a random number of symbols, activating another avalanche.
  • Magic Transform: Transforms all the spades and heart symbols into another high paying symbol.

These are listed in how likely you are to trigger them, and conveniently, how big a wins you are likely to get because of the bonus slot feature.

The Key to the Free Spins: After every spin, a key symbol starts on position 25, or the leftmost symbols at the end of the "swirly".

It can never be part of a win, but every win potentially gets it closer to the centre.

If it manages to get there you get to enter the free spins land where you can pick from any four of drinking establishment... but only once you've collected enough keys.

Each time you enter the free spins you collect one key. At first that means you only get a choice of one free spin bonus, but to be honest, they all pay more or less the same, except perhaps for the Golden pot, with it's higher symbol pays.

  • Star Bar - 1 Key: You get 7 free spins where after each spin the Starfall Wild feature triggers.
  • Lava Lair - 4 keys: You get 3 free spins where after each spin the Dragon Destroy feature triggers.
  • Lucky Mug - 9 keys: You get 4 free spins where after each spin the Irish Luck feature triggers.
  • Golden Pot - 16 keys: You get 2 free spins where after every spin the Magic Transform feature triggers.


  • High RTP of 96.62%
  • Fun Irish slot theme
  • Avalanching reels offer more wins
  • 4 free spins bonuses


  • Low max win of 500x bet
  • Bonus features don't show up often

Finn And The Swirly Spin Review Conclusion

Don't underestimate the lasting potential of this NetEnt phone slot; sure getting wins much more than 30x your bet aren't easy to find, but this whole game screams fun.

From your host the Leprechaun Finn, sitting by the side of the reels, reacting to every win, or randomly giving you one of four potential features on any spin.

To those wonderful swirly spin cascading wins and exploding wilds that brings you closer to the great free spin bars in the sky.

It can be a little frustrating at times, when those damn keys don't give you the free spin Guinness you want regularly enough, but you won't be losing too much whilst you wait, so it's easily forgiven.

This Finn and the Swirly Spin slot machine managed to surprise us, mixing theme, unique features and 96.62% RTP to create a truly wondrous Emerald Isle game.
