Finn and the Swirly Spin by NetEnt (Net Entertainment) is played across an unusual 5×5 game-play setup (5 reels and 5 rows). Instead of classic paylines, there are Cluster Pays.

The player can select one of ten offered betting levels. Each level enlarges the amount of the total bet per spin by 10 coins. Total bet occupies the values between 10 and 100 (maximum bet).

The maximum base game payout (jackpot) is set at 500 times the amount wagered on one win match.

The theoretical RTP percentage is set at 96.6%, which describes the game as an online video slot with medium to high volatility.

The game comes with four base game features, the free spins feature and sticky wild symbols. An additional bonus round is excluded.

Auto-play mode is present. Through it, one can adjust between 10 and 1000 automatic spins.


The game is compatible with all smartphone or tablet devices that are powered either by Android or by iOS. Given the fact that Finn and the Swirly Spin mobile can be played in instant play mode (via web browser and Adobe Flash player), no specific mobile phone app needs to be installed.

There are also two options: to play Finn and the Swirly Spin for free or to test your luck and play Finn and the Swirly Spin for real money. The vast majority of online casinos allow both real money and demo (free) mode.

Additional Features

Cluster Pays means that symbols included in a winning combination get destroyed and the remaining symbols fall into their locations. This is known as “avalanche”.


If the wild (a star) is included in a win, it will explode, destroying all symbols in the same reel or row. Sticky wild appears only during free spins (Lava Lair game).

The free spins feature is triggered when the key symbol is placed in the middle of the reels and there are no wins in that particular spin. The feature comes with several different games that are being unlocked gradually in the following order while playing: Star Bar, Lava Lair, Lucky Mug, Golden Pot.

Base game features:

  • Starfall Wilds inserts two wilds in random positions. If a win doesn’t occur, it adds one extra wild until the payout happens.
  • Dragon Destroy destroys random symbols, creating an avalanche.
  • Irish Luck covers one row or reel in same symbols.
  • Magic Transform turns lower paying symbols (heart and spade) into higher paying ones.


It is worth playing Finn and the Swirly at casino online, while it offers a wide range of additional features that can potentially bring one massive payout!
