Finn and the Swirly Spin is a 5-reel slot developed by NetEnt, with a 96.62% RTP, medium volatility, and a 300x maximum win. Its defining mechanic is the spiral path wins follow, leading to potential bonus features. Available at Ontario iGaming-licensed casinos regulated by the AGCO.

Finn and the Swirly Spin is a unique slot worth trying if you’re looking for something beyond traditional paylines, particularly if you enjoy games where the journey itself can unlock rewards. The game’s central spiral mechanic creates a distinct flow that keeps things interesting, though it might feel slow for players who prefer constant base game action.

  • Standout: The spiral path mechanic that collects keys to unlock bonus features.

How Finn and the Swirly Spin Actually Plays

Finn and the Swirly Spin doesn’t use traditional paylines; instead, wins are formed by landing three or more matching symbols in a horizontal or vertical line. The unique aspect is how symbols appear on a 5×5 grid but don’t cascade or respin in the usual way. Instead, winning symbols are removed, and the remaining symbols shift to fill the gaps, creating a spiral effect that moves symbols towards the centre of the grid. This continuous shifting keeps the game dynamic, and it’s this movement that’s key to unlocking the game’s bonus features. The game’s rhythm is steady; it’s not a slot that throws frequent small wins at you in the base game. The real excitement builds as you collect keys from winning combinations that land on the star symbol, which then move towards the centre. This progression feels more like an adventure than a typical slot spin, and the payout potential is more likely to come from the bonus features than from standalone base game wins.

Bonus Features

Free Spins

The Free Spins feature in Finn and the Swirly Spin is triggered by collecting keys. These keys are generated from winning combinations that land on the star symbol, which then makes its way to the centre of the spiral path. You’ll need to collect a certain number of keys to unlock different types of free spins. Each key you collect is added to a meter. Four keys unlock the Star Bar, which awards 5 free spins with the “Starfall Wilds” feature. Eight keys unlock the Lucky Mug, offering 5 free spins with the “Dragon Destroy” feature. Twelve keys unlock the Golden Pot, providing 5 free spins with the “Irish Luck” feature. Sixteen keys unlock the Leprechaun’s Chest, which grants 5 free spins with the “Coin Bonus” feature. The maximum win potential is 300x your bet, and this is primarily achievable through the enhanced free spins rounds. The wait for these features can be long, but the variety of bonuses keeps the anticipation high.

RTP and Volatility: What to Expect

Finn and the Swirly Spin carries a globally reported RTP of 96.62%, which is a solid figure and generally competitive within the Ontario online casino market. This RTP indicates that, over millions of spins, the game is theoretically designed to return approximately 96.62% of all wagered money back to players. The volatility is described as medium. This suggests that you won’t experience extremely long dry spells without any wins, nor will you likely see massive payouts on every other spin. Instead, you can expect a more balanced experience where wins might come in moderate sizes, and the larger payouts are more likely to be tied to the bonus features. This medium volatility means the game can be suitable for a range of bankrolls, but it’s still wise to manage your funds, as even medium volatility slots can have periods of quiet play before a significant win or bonus feature occurs.
