Finn and the Swirly Spin: NetEnt's spiral-grid oddity
Finn and the Swirly Spin is one of NetEnt's most inventive slots, and it looks like nothing else in the lobby. Symbols spiral inward across a grid rather than dropping down reels, and the whole game is wrapped in a cheerful Irish theme. It is playful, a little strange, and packed with features. We find it one of the more characterful titles the studio has made.
The mechanics
Instead of conventional reels, Finn and the Swirly Spin uses a spiral layout. Winning symbols form clusters, and when they pay, they vanish and the remaining symbols swirl inward along the spiral to fill the gaps, which can chain into further wins from a single spin. This cluster-and-avalanche style keeps each spin alive longer than a standard payline game. Wild symbols travel from the outer corner of the grid toward the centre, clearing symbols as they go. The base game also has a set of randomly triggered features that can drop wilds, transform symbols or otherwise shake up the grid, so no two sessions feel quite the same.
The free spins features
The bonus side of Finn and the Swirly Spin is unusually deep. To reach the free spins you unlock a key by clearing symbols and getting it to the centre of the spiral, and there are four different free spins modes, each with its own twist. Some add extra wilds, some convert symbols into higher-value ones, and they vary in how many spins and what kind of help they give. Cycling through those modes is part of the appeal, and it gives the game far more variety than a single repeating bonus. The maximum win lands in the region of a few thousand times your stake, which matches its measured variance.
RTP and volatility
The RTP is around 96.25%, a standard figure for the studio. Volatility sits in the low to medium range, so the cluster wins and avalanches keep the balance ticking over without violent swings. That makes it more forgiving than NetEnt's high-variance releases and a comfortable game for longer sessions. Our volatility guide explains what low-to-medium variance means in practice, and our RTP guide covers how to read the return figure shown at your casino before you commit.
How to play Finn and the Swirly Spin
Set your bet level and coin value, then spin. Because the grid works differently from a normal slot, we strongly suggest a demo run first to get used to how clusters pay, how the wilds travel, and how the key unlocks the free spins. Once you understand the spiral, it becomes very readable. If you find the game through a welcome offer, check the wagering on any winnings, the kind of detail our bonuses guide insists you confirm. For a broader grounding in slot features and formats, our slots guide is a good companion read. Finn and the Swirly Spin is from NetEnt, whose catalogue we cover in our NetEnt review.
The verdict
Strengths: a genuinely original spiral grid, cluster pays with avalanches, four distinct free spins modes and forgiving low-to-medium variance. Weaknesses: the unusual layout takes a few spins to learn, and the max win is moderate rather than huge. Finn and the Swirly Spin is a great pick for players who want something different and feature-rich without extreme risk, and a less obvious choice for anyone after a big-multiplier chase. Try the demo, then play at a licensed casino from our reviews, and stay sensible with our responsible gambling advice. 18+.
