Finn and the Swirly Spin is a 5x5 cluster pays slot from NetEnt, released in November 2017. It ditches traditional reels in favour of a spiral grid where symbols cascade inward from the edges toward the centre, giving it a look and feel unlike most slots. The Irish leprechaun theme is cheerful and well executed, but the mechanics are what set this game apart.
Grid and Paylines
There are no fixed paylines here. Instead, Finn and the Swirly Spin uses a 5x5 grid and a cluster pays system. Wins are formed by landing three or more matching symbols in a horizontal or vertical cluster. When a win lands, those symbols disappear and new ones cascade into their positions, which can chain into multiple wins from a single spin. The spiral layout means symbols enter from the outer positions and swirl toward the centre key position - hit that key enough times and you unlock the free spins modes.
RTP and Volatility
The RTP is 96.62%, which sits comfortably above the industry average of around 96%. Volatility is low to medium, so the game delivers wins fairly regularly rather than making you wait through long dry spells for a big hit. The maximum win is 840x your stake. Bets run from £0.10 to £100 per spin.
Random Features
Four random features can trigger at any point during the base game:
- Starfall Wilds - Two or more wild symbols are placed randomly on the grid. Additional wilds keep landing until at least one winning cluster is formed.
- Dragon Destroy - A dragon blasts a random set of symbols off the grid, triggering a fresh cascade. The destruction is guaranteed to produce a win.
- Irish Luck - A vertical or horizontal line of symbols transforms into a single matching symbol, creating an instant winning cluster.
- Magic Transform - Spade and heart symbols across the grid convert into higher-value symbols, boosting the potential of whatever lands next.
Free Spins Modes
The key at the centre of the spiral grid is what you are chasing. Every time a symbol lands on the key position, it collects and moves the key inward. Collect enough keys and you unlock one of four free spins modes, each tied to a different threshold:
- Star Bar - 1 key unlocks 7 free spins with Starfall Wilds active throughout.
- Lava Lair - 4 keys unlocks 3 free spins with Dragon Destroy on every spin.
- Lucky Mug - 9 keys unlocks 4 free spins with Irish Luck triggering constantly.
- Golden Pot - 16 keys unlocks 2 free spins with Magic Transform applied, turning lower symbols into premium ones before each spin drops.
Star Bar is the easiest to reach and suits lower-variance play. Golden Pot is the longest grind but the Magic Transform feature during free spins gives it real payout potential.
Mobile
Finn and the Swirly Spin runs cleanly on mobile browsers with no separate app needed. NetEnt designed the game's interface to scale across screen sizes, and the spiral grid actually displays well on portrait mode. Touch controls work as expected throughout base game and features.
Verdict
Finn and the Swirly Spin earns its reputation as one of NetEnt's more inventive releases. The spiral grid and key-collection mechanic give it a clear progression structure that most slots lack - you are working toward something specific with each spin rather than just waiting for a scatter to land. The four random features keep the base game lively, and the variety of free spins modes means different players can find their preferred risk level. At 96.62% RTP and low-medium volatility, it is a solid choice whether you play casually or with a specific strategy in mind.
