Finn and the Swirly Spin Slot Review
The clue here is in the name: Finn!
You can try the free play demo for Finn and the Swirly Spin on this page before exploring more online slots or comparing UK casinos.
Finn is an Irish name and this is a luck-of-the-Irish themed game, but with a difference. In fact, with quite a lot of differences.
The first one you’ll notice in this Finn and the Swirly Spin slot is that there are no reels! Or rather, the reels are a single giant spiral. Spins come with an avalanche feature that works as a respin.
The Finn and the Swirly Spin slot game is colourful, with cartoon graphics, and a series of different backdrops.
Finn and the Swirly Spin slot was released in 2017 and is different from the run of the mill Irish games, which tend to have rather retro graphics and extremely bright colours – mostly extremely bright greens and reds. Irish games tend, in our opinion, to swap visual sophistication for bright friendly colours, simple gameplay and big prizes.
Should you set this spiral spinning though?

NetEnt – the developers of Finn and the Swirly Spin Slot
Finn and the Swirly Spin slot is released by NetEnt. NetEnt aren’t the biggest gaming company in the world. But they very nearly are. The company doesn’t just make games, it has an interest also in producing software that runs casinos.
NetEnt has, according to the industry audit site we use, around one-fifth of the world slots market and nearly one-third of the European market.
This means that NetEnt games are always popular and always highly visible.
Their big titles are the biggest, including the UK’s favourite game, Starburst, and the top 10 hits, Gonzo’s Quest, both of which are major favourites in the free spins market.
They keep releasing games, and they keep having hits.
This game is one of them, rated in the 50s, with a related title, Finn’s Golden Tavern.
The Facts and Figures
Finn and the Swirly Spin slot has a theoretical return to player of 96.62%. This translates to a house edge of 3.38%. This figure relates well to the industry average. RTP records how a game is intended to do over the course of its lifetime for all players and if players behave in a particular way. It is not a measure of how you will do in your interaction with the game – that could be much better or much worse.
This game has low to medium variance (also called volatility). This means that the game is more likely – than the industry average – to pay out prizes more often, but they’re more likely to be lower in value. Again, this is not a guarantee of how your game will go, it’s a long-term measure.
Minimum betting is 0.1 coins (usually 10p), and the maximum stake is 100 coins (£100). The top prize is 50,000 coins.
The game is a five-by-five grid with 25 symbols in play (though it doesn’t have a standard reel set up), and because of that, it doesn’t have recorded pay-lines.
You can play this game on any mobile, desktop or tablet device that delivers JavaScript and HTML5.
Playing the Finn and the Swirly Spin Slot Game Online
The reels are atypical, but playing this game is very simple for any player who’s used NetEnt games.
The control panel runs along the bottom of the screen. In the game frame, you’ll find extra controls, including the sound controls, an autoplay option, more help options, and settings.
On the control panel, we’ll start from the left, where the information button opens up the pay tables and game rules. Then your bet level indicator, which is controlled with the neighbouring level control and a coin size metre on the other side of the central console. There you’ll find the usual set up of a spin button flanked by a max bet button and an autoplay button. Your balance is recorded at the far right.
Payouts
The pay table opens with card symbols and climbs into a set of themed lucky symbols.
The shamrock pays 10, 30, and 80 coins at bet level 1. The horseshoe pays 10, 40, and 100. The acorn pays 10, 50, and 120, and the diamond pays 20, 100, and 500.
Then we’re onto a load of special symbols.
Finn and the Swirly Spin Slot Bonuses
In the main game:
- Starfall Wilds put extra wilds on the reels.
- The Dragon Destroy feature is a respin that takes out extra symbols.
- The Irish Luck feature puts an extra symbol in for a guaranteed win.
- The Magic Transform turns spaces and hearts into better symbols.
- A key scatter triggers the free spins round, with four options tied to features.
- Star Bar Free Spins come from a single key. There are seven spins and 2 to 5 wilds on each spin.
- Lava Lair Free Spins come from four keys give you three spins with a random number of symbols destroyed for a respin on each spin. You also get a sticky wild.
- Lucky Mug Free Spins come with nine keys. There are four spins and a guaranteed win on each spin.
- Golden Pot Free Spins is triggered by 16 keys awarding two free spins with no lower value symbols.
The Verdict
There’s so much to enjoy with Finn. Irish games can be a bit samey, and, to be honest, we don’t like the aesthetics of a lot of these games (though that’s entirely personal).
This game is a refreshing take on Irish theming with something different wherever you look. The spiral is a novelty that you’ll need to take a look at to see if you like it. Otherwise, there’s lots of familiar features – wilds, respins, subs – given a nice new twist and delivered with great style in graphics and sounds.
We recommend Finn and the Swirly Spin slot, and while it doesn’t have a jackpot there is a chance to buck the low-to-medium volatility rating and win some really big prizes if you hit the bonus features here.
