Pros and cons of Finn and the Swirly Spin

Features of Finn and the Swirly Spin slot

Finn and the Swirly Spin does not use the traditional reel and payline format. Instead, it features a 5x5 grid where wins form both vertically and horizontally.
Any combination of three identical symbols grants a prize, regardless of their position.

However, this is not a "cluster pays" slot where large blocks count as a single win. Here, a line generates its own reward, and when a winning combination occurs, the symbols disappear from the screen, allowing the remaining ones to "swirl" toward the centre.

The goal in the base game is to move a special key from the first position to the lock in the middle of the board in twenty-four "steps." This unlocks the free spins round.
Essentially, the objective is to clear symbols to pave the way and reveal more winnings or at least a bonus. Note that any losing spin will send the key back to its starting position.

A spiral pattern dictates how this process works: new symbols appear in the bottom-left corner and move clockwise until they complete a full rotation, at which point they travel in an inner loop toward the centre.

Moreover, a regular win creates a star-shaped wild. These symbols substitute others to help form winning combinations.

However, a win that includes a wild does not generate another star: the involved wilds simply explode, destroying all adjacent symbols.

This is important because clearing the screen and reaching the lock is how Finn, the Irish leprechaun and the game's protagonist, gains access to free spins. As soon as this happens, new symbols will be added to the stone grid to repeat the cycle.

Furthermore, Finn and the Swirly Spin slot can be played on various devices—including smartphones and tablets—with a minimum bet of $0.10.

In terms of visuals, the slot features 3D animated graphics similar to a Pixar movie, giving it a very cartoonish and cheerful look.

The backdrop is the Emerald Isle, an astonishing green landscape of plains with trees, hills, and rivers—the home of Finn, who sets the mood by playing Celtic melodies on his magic flute.

Regarding standard symbols, there are only six: a heart, a spade, a four-leaf clover, a lucky horseshoe, an acorn, and a ruby. The latter is the most lucrative, as landing five in a row grants a prize of fifty times your bet.

There is also a wild symbol that, as mentioned earlier, appears under special circumstances and replaces all others except the scatter.

Swirly Spin avalanche mechanic

There are 25 spaces on the board, starting from the bottom-left corner and swirling toward the centre of the screen.

The symbols load in that order, and when you score a win, the combination disappears, and more symbols fall, spiralling around the 5x5 grid.

It works like Fruit Party's cascading reels system, except the symbols move around a coil instead of dropping from above.

Wild Generation

You'll receive a payout when three or more matching symbols land vertically or horizontally in a row.

Once a win is achieved, the combination explodes, and a wild (star) is created in its place while new symbols load from the bottom of the first reel.

Apart from helping you win, the wild also explodes, taking all adjacent symbols with it.

Four Random Features

During regular spins, Finn can work his magic and summon random features by casting spells.

There are a total of four features you can obtain after any spin, thanks to the leprechaun.

• Irish Luck: A horizontal/vertical line of one symbol type is added to guarantee a win and an avalanche.
• Starfall Wild: Two to five extra wilds are randomly placed on the reels.
• Dragon Destroy: A random number of symbols are destroyed, triggering another avalanche.
• Magic Transform: All spade and heart symbols turn into another high-paying symbol.

These are listed based on their activation probability and, conveniently, their potential for big rewards.

The Free Spins Key

After each spin, a key (scatter symbol) frozen in an ice block appears in position twenty-five of the grid.

This key will never be part of a winning combination, but each win moves it closer to the centre lock.

If you reach it, you'll enter the land of free spins, where you can choose from four different free spin types, each corresponding to one of the random features. However, to access them, you must collect a specific number of keys.

Upon activating free spins, you'll collect a scatter symbol, meaning you can only choose one bonus, although, to be honest, they all pay roughly the same—except for the Golden Pot.

• Star Bar: 1 key grants 7 free spins, with the Starfall Wild feature activated after each spin.
• Lava Lair: 4 keys grant 3 free spins, with the Dragon Destroy feature activated after each spin.
• Lucky Mug: 9 keys grant 4 free spins, with the Irish Luck feature activated after each spin.
• Golden Pot: 16 keys grant 2 free spins, with the Magic Transform feature activated after each spin.

Volatility and RTP of Finn and the Swirly Spin from NetEnt

The return-to-player (RTP) percentage of Finn and the Swirly Spin is 96.62%, a solid stat for playing and having fun.

In terms of inherent risk, the game has low-medium volatility, meaning its prizes are not extremely high but frequent enough to keep you engaged.

Our verdict of Finn and the Swirly Spin from NetEnt

NetEnt has done it again: they've designed a unique slot that cannot be compared to any other, and they deserve all the praise for it. We enjoyed playing Finn and the Swirly Spin, though we must admit the swirling pattern made us dizzy after a while.

Don't underestimate this game's potential. While scoring wins above 30x the bet isn't easy, everything else screams fun.

From Finn, the leprechaun host, reacting to each win or randomly granting one of four features, to the cascading reels and expanding wilds that bring you closer to the free spins bars in the sky.

It may be a bit frustrating when the keys don't grant the desired number of spins regularly, but you won't lose much money while waiting, so this is easily forgiven.

Finn and the Swirly Spin surprised us by blending an Irish theme with unique features to create an entertaining slot. If you liked the leprechaun theme, we recommend trying Gold Party by Pragmatic Play.
