Finn And The Swirly Spin is a 5×5 grid slot from NetEnt with a whimsical Irish leprechaun theme, using a cluster-pays system instead of paylines: groups of 3 or more matching symbols landing horizontally or vertically adjacent anywhere on the grid form wins.

Winning clusters disappear and trigger an avalanche, but instead of falling straight down, replacement symbols travel inward along a spiral path toward the center of the grid — a distinctive visual twist on the standard cascade mechanic. Avalanches keep chaining as long as new winning clusters keep forming from a single spin. A separate Coin Win feature can shower coin symbols onto the reels that transform into matching high-value symbols as part of a Lucky Spins round. The 5×5 grid and cluster-pays structure give it noticeably more combination variety than a standard fixed-payline NetEnt slot.

Cons

- Spiral cascade mechanic can take a spin or two to get used to
