Finn And The Swirly Spin Pros & Cons
Finn and The Swirly Spin delivers classic Aristocrat action with a proven track record. The choice-based free spins and stacked symbols create a good variety, but the RTP and max win won't impress everyone.
- Genuinely unique spiral mechanic — no other NetEnt slot moves symbols this way
- 4 free spins mode choices give real player agency over the feature experience
- Endless Free Spins mode can produce very long self-extending feature sessions
- 4 random base game features keep base spins between key advances interesting
- 96.62% RTP is competitive for low–medium volatility
- €0.10 minimum bet — extremely accessible entry point
- 300x max win is the lowest ceiling of any slot in this review set
- 22% hit frequency is lower than the low-volatility classification implies

- The spiral concept requires a few sessions to fully internalize — less immediately intuitive than reel slots
Finn and the Swirly Spin Slot Review
Most slots in 2017 were still running the same 5x3 reel setup with paylines that hadn’t changed since the 1990s. Finn and the Swirly Spin, released in November 2017, did something genuinely different: it scrapped the reel concept entirely. The playing field is a 5x5 grid and symbols don’t fall from above — they enter from the bottom-left corner and spiral inward toward the centre, like water draining. Winning clusters disappear and the remaining symbols continue their inward journey. No paylines. Wins form from three or more matching symbols in adjacent horizontal or vertical positions.
The centrepiece is the Free Spins Key system. A key symbol sits at the starting position at the bottom-left of the grid. Every win moves it one step closer to the centre. When it reaches the middle, free spins trigger — and you choose from four distinct modes: Coin Win Spins, Lucky Wilds Spins, Endless Free Spins or the Super Coin Win. Four random base game features — Starfall Wilds, Dragon Destroy, Irish Luck, Magic Transform — fire periodically to keep base game sessions alive. 96.62% RTP, low–medium volatility, €0.10 to €200 bets. The 300x max win is modest, but the mechanic is unlike anything else in the NetEnt catalog.

Key Features & Mechanics
🎒 Swirly Spin Mechanic — Symbols Spiral Inward No Reels, No Paylines — 5x5 Cluster Grid
Forget reels. Finn and the Swirly Spin uses a flat 5x5 grid where every symbol has a fixed path spiralling from the bottom-left corner through to the centre position. When you hit spin, new symbols enter from the bottom-left and travel the spiral inward. Winning clusters — three or more of the same symbol touching horizontally or vertically — disappear. The remaining symbols don’t fall from above like a cascade; they continue their inward spiral journey, potentially connecting with other symbols to form new clusters. If a win includes a Wild, the Wild explodes and destroys adjacent symbols too, opening up more cluster-forming possibilities. If a win doesn’t include a Wild, a new Wild appears on the grid at the position just vacated. It’s a genuinely different experience from a standard slot — the flow of symbols has a rhythm to it, and watching a cluster chain while symbols spiral inward feels like no other game NetEnt built before or since.
🔑 Free Spins Key — 4 Modes to Choose From Every Win Moves the Key — Reach the Centre to Trigger
A golden key symbol lives at the starting position (bottom-left) of the spiral path at all times. Every winning cluster moves the key one step closer to the centre. The key does not reset between spins — it keeps its position and keeps advancing with each subsequent win. When it finally reaches the centre position, you choose from four free spins modes. Coin Win Spins: each spin produces a coin win rather than symbol-based clusters — guaranteed returns every spin. Lucky Wilds Spins: multiple wild symbols appear on the grid each spin, with Wild explosions driving large cluster chains. Endless Free Spins: free spins with no fixed count — the key resets and continues advancing; each time it reaches the centre during the feature, more free spins are added. Super Coin Win: a single high-value coin win payout. The choice is meaningful and player-driven — the mode you select sets the entire character of your feature session.
🍁 4 Random Base Game Features Starfall Wilds — Dragon Destroy — Irish Luck — Magic Transform
Four random features can fire during base game spins, each changing the grid state before the spin resolves. Starfall Wilds drops between two and five additional Wild symbols randomly onto the grid, giving the incoming symbol spiral more wild positions to interact with. Dragon Destroy activates when no winning cluster occurs — a dragon appears and destroys a set of random symbols, which can break up symbol groups preventing clusters from forming and open the grid for the next spin. Irish Luck guarantees that the current spin produces at least one winning cluster — useful during dry stretches where the spiral isn’t forming natural connections. Magic Transform converts all spade and heart symbols on the grid into higher-paying symbols, shifting the value composition of the grid before the spin evaluates. These four features mean that even during base game spins between key advances, something is happening on a reasonably regular basis.

FAQ - Frequently Asked Questions
How does the spiral mechanic work exactly?
The 5x5 grid has a fixed spiral path running from the bottom-left corner inward to the centre position. Every new symbol that enters the grid does so at the bottom-left entry point and travels along this spiral path toward the centre. When you spin, the existing symbols already on the grid move one step inward along the path and new symbols enter from the entry point. Winning clusters — three or more matching symbols adjacent horizontally or vertically — are removed, and the remaining symbols continue their inward movement. The result is that unlike a standard cascade where symbols fall vertically from above, these symbols flow in a curve, and cluster formations emerge from that curved movement in ways that don’t happen on a straight reel system. The key symbol travels the same path and advances one step toward the centre with each winning cluster.
Which of the four free spins modes is the best?
It depends entirely on what you value in a session. Endless Free Spins is the fan favourite because the key resets and starts advancing again during the feature — every time it reaches the centre, additional free spins are awarded. A session where the key reaches the centre multiple times during Endless Free Spins can run for a very long time. Lucky Wilds Spins is the highest-volatility mode of the four — multiple wilds appear each spin, wild explosions chain into cluster formations, and the best individual spin values in free spins come from this mode. Coin Win Spins and Super Coin Win guarantee a payout but are less exciting mechanically. For session length: Endless Free Spins. For raw win potential within the feature: Lucky Wilds Spins. For guaranteed consistent return: Coin Win Spins.
Is Finn and the Swirly Spin available at Canadian casinos?
Yes — available at Ontario-regulated casinos carrying NetEnt software and at most international platforms serving Canadian players. The 96.62% RTP is consistent across operators. Stakes run from €0.10 to €200 with CAD equivalent applied. All four free spins modes, the spiral mechanic, and the four random base game features are fully accessible without regional restrictions. Mobile performance through NetEnt Touch technology is reliable. Bonus buy is not available — the key system is the only path to the feature, and it advances only through winning clusters.
How does Wild explosion work?
When a Wild symbol contributes to a winning cluster, instead of simply disappearing with the rest of the winning symbols, it explodes. The explosion destroys all symbols in the positions immediately adjacent to the Wild — the positions directly above, below, left and right of where the Wild sat. Those destroyed symbols are removed from the grid and open up new positions for incoming symbols on the next cascade step. The explosion is beneficial because it removes symbols that might be blocking cluster formations elsewhere on the grid, and the vacated positions receive new incoming symbols that may form additional clusters. When no Wild is part of a winning cluster, a new Wild appears at the position just vacated by that win — so the grid tends to maintain a Wild presence that feeds back into subsequent cluster formation.
Why is the max win only 300x?
The 300x ceiling is a direct consequence of the cluster-pay structure and the low-medium volatility classification. On a 5x5 grid with no paylines and cluster-size-based payouts, the maximum possible cluster covers all 25 grid positions with the same symbol — which pays the top paytable value but still caps at 300x because individual cluster pay values are modest by design. The game compensates through session length — particularly the Endless Free Spins mode, which can chain repeated feature cycles and accumulate smaller wins over a sustained period. Players who want a slot where a single spin can pay 2,000x will be disappointed by Finn and the Swirly Spin. Players who want an unusually long, consistently active session at 96.62% RTP with a genuinely different mechanic will find the 300x ceiling more acceptable.
What is the Irish theme?
Finn is a small Irish leprechaun character who appears as the top premium symbol. The overall theme draws from traditional Irish lucky charm imagery — shamrocks, harps, horseshoes, pots of gold — rendered in a bright, cheerful green and gold colour palette. The background depicts an Irish countryside at night with fireflies and a magical atmosphere that fits the swirling spiral mechanic. The four card suit symbols (spades, hearts, diamonds, clubs) fill the low-value positions, keeping the Irish charm theme consistent throughout the paytable. The Dragon that appears for the Dragon Destroy random feature is a playful break from the Irish theme — it swoops in from outside the grid to breathe fire on symbols before retreating. The overall presentation is family-friendly and deliberately lighthearted, which contrasts with the mechanical complexity underneath.
