Finn and the Swirly Spin online slot game
Many slots use a similar theme and storyline to Finn and the Swirly Spin, yet NetEnt has put clear effort into giving this game its own identity. Several free spins bonus games can be triggered, creating opportunities for substantial wins, although no outcome is guaranteed.
Theme and storyline
Leprechauns have appeared in dozens of earlier slot games, but NetEnt gives Finn and the Swirly Spin a somewhat different treatment. The familiar objective of landing the available pot of gold remains, while the storyline brings an additional layer to the Celtic setting.
The game takes players through various levels. Without revealing spoilers, Finn and the Swirly Spin offers several reasons to investigate its features. The leprechaun beside the reels is called Finn, which explains the title and helps give the Celtic theme an authentic feel.
Graphics, sounds, and animations
Finn and the Swirly Spin showcases some of NetEnt’s strongest graphics, fitting for the Swedish developer behind many prominent slot games. Animation begins on the reels, which use a 5x5 grid of spaces instead of a conventional slot layout. Some audio elements feel basic and do not match the visual presentation, but the graphics and animations are particularly polished.
Top Casinos to Play Finn and the Swirly Spin:
Gameplay
The first notable feature of Finn and the Swirly Spin is its departure from the standard reels found in most slots. NetEnt uses a 5x5 grid instead, with every spin producing a swirl of symbols. A win is formed when three or more matching symbols are adjacent vertically or horizontally, creating plenty of potential combinations.
The grid contains a golden acorn, four-leaf clover, horseshoe, wooden heart and wooden spade. Ruby symbols are the glittering prizes players will be looking for because they are the highest payout symbol available. A free spin key appears on the grid after every spin, but the bonus only activates if it reaches the required position.
Finn and the Swirly Spin’s gameplay is sufficiently different from other slots to make a strong impression. Some players, however, have considered the payout levels rather low. Larger wins are possible too, so the experience can involve the swings and roundabouts associated with slot play.
Bonuses and free spins
NetEnt’s slot bonuses are often a highlight, and Finn and the Swirly Spin includes no fewer than four free spin bonus rounds: Star Bar, Lava Lair, Golden Pot and Lucky Mug. Star Bar needs only one key to trigger, whereas Lucky Mug requires 16 keys to unlock. The random features appear fairly regularly, and the review identifies these rounds as the point at which the game’s bigger wins occur.
Bet sizes, RTP and variance
NetEnt Slots use a distinctive coin-based pay system, with coins setting the stake rather than a separate cash payment for every spin. Set ‘Level Bet’ from 1 to 10, with ‘Max Bet’ applying to level 10. Each level adds 10 coins per spin, producing a 10-100 coin range. Every coin can carry a cash value of 0.01-2.00, so the cash stake runs from 0.10 to 200.00 per spin. Finn and the Swirly Spin lists an RTP of 96.62% and low to medium variance.
Conclusion
By replacing the usual reel arrangement, Finn and the Swirly Spin stands out as a distinctive NetEnt creation. Its swirling grid offers a different way to play and could potentially influence other slot developers. Four free spins bonus games add further appeal, although they do not ensure a win. The review presents this as a slot likely to interest players who enjoy unusual mechanics.
