Storyline of Finn and the Swirly Spin Slot
NetEnt uses an Irish theme for the slot game. The game settings are in a magical forest with the funny leprechaun called Finn. Also, the overall design features a fantasy tale with a bright-coloured background.
On top of that, it features an ambient musical soundtrack that helps to make the game even more entertaining. Similar to many other Irish-themed games, the aim here is to spin the reels to reveal the pot of gold at the end of the rainbow.
How to Play Finn and the Swirly Spin Slot
The slot game features an unusual, yet straightforward gameplay on a 5×5 grid. Despite having the swirling reels rather than the usual vertical ones, wins are created in much the same way. A winning combination happens when a group of three or more matching symbols lands either vertically or horizontally to each other.
After matching the symbols, an explosion occurs that leaves a space to fill with other symbols as the avalanche feature. The ultimate bargain is unlocking the pot of gold at the end of the rainbow as it contains great prizes.
The game has an RTP set at 96% and a low to medium volatility level which is highly attractive especially for beginners.
Symbols and Special Features
The leprechaun — Finn — acts as the highest value symbol. In addition to the leprechaun symbol, there are a number of Irish-themed icons. Some of the other symbols available include shamrocks, diamonds, cloves and golden horseshoes and all are symbols of luck.
Excitingly, there are a number of bonus features in this game. First up is the Dragon Destroy which destroys a random number of symbols on the reels to get you another avalanche feature.
There’s also the Irish Luck feature that gives you a horizontal or vertical line of one symbol to get you a guaranteed win in the game. Other captivating casino bonus features within the game include the wild star feature. Activating this means you can get two to five more wilds on the reels to get bigger wins.
Finally, there’s the Magic Transform that turns all the heart or spade symbols into higher-paying ones on the reels.
Finn and the Swirly Spin Slot Free Spins
In addition to those bonuses, players get a chance to try out the four free spin features and these include the Lava Lair, Star Bar, Lucky Mug, and Golden Pot. You can trigger these free spins by landing a free spins key scatter in the central position of these swirling reels.
First up is the Star Bar spins and you only need one key to activate this feature. Afterwards, you get seven free spins plus 2-5 wilds added to the reels.
You need four scatters to activate the Lava Lair. This gives you three free spins. Also, the symbols are destroyed giving you an additional win plus a second avalanche. Triggering the Lucky Mug needs nine scatters to provide you with four free spins and a line of one kind of symbol for guaranteed wins on each of the spins.
Lastly, the golden pot needs up to 16 keys to start. Afterwards, it gives you two free spins containing the heart and spade symbols that turn into high-value symbols with each spin.
Try out this Irish-themed game at any new casino if you want to spice up your slot experience. Get to experience the unique spiral feature with the traditional 5×5 grid. Also, check out the rich gameplay and attractive payouts.
