Finn and the Swirly Spin Slot

Finn and the Swirly Spin Slot

Who doesn’t love a good NetEnt slot? With a headquarters in Sweden, this innovative content developer has been producing top games since 1996 – this means they have over 20 years experience in iGaming. Previous NetEnt games which online slot fans may know are the space-themed Starburst or fantasy-themed Jack and the Beanstalk, to name but a few. Their slots are known for not only offering exciting gameplay and top-draw graphics but also lots of cool bonus features.

With Finn and the Swirly Spin, they have come up trumps again with a slot that cements their status as a leading supplier of the best online slot games. But what do you need to know about it before you play?

Finn and the Swirly Spin game background

The basic game theme is Irish, which may not sound overly original. There have been many games based on this theme over the years but NetEnt manages to inject new life into it. The game setting takes you to the Emerald Isle with an exciting background choc full of green pastures, trees and even a rainbow. To the left of the game is protagonist Finn, a Leprechaun merrily playing the flute until a random bonus occurs or the free spins key reaches the middle of the spiral. A major part of this is the innovative cluster pay game design with Spin Mechanics. The impressive graphics in game help to keep the experience engaging with features from swaying trees in the background to the in-game cinematics when random bonuses take place.


The symbols enter the 25 square spiral from the bottom left corner rather than dropping in from above, winning symbols are formed by matching up at least 3 of the same symbol. When this happens, winning symbols disappear and are replaced by new ones from the same corner until no more winning combos are hit. As combinations are removed and new symbols enter the square the free spin key is pushed around the spiral; more information below. Visually, this slot looks amazing with vibrant colours and well-defined images. Fans of this type of slot will be pleased to see all the symbols you would expect present, such as spades, hearts, acorns, rubies and clovers that when matched up in 3 gain a starfall wild.

Finn and the Swirly Spin RTP

One key factor most online slot fans look at is RTP (Return to Player). For this NetEnt title, it is reported to be 96.62%, which compares well with other modern slots. Look out for the Ruby symbol when playing – 5 of these on a payline gives 50 times your original stake. This is classed as a medium volatility title so you shouldn’t be forced to wait too long for the pay-outs to appear, there should be fairly frequent wins. The ability to change the level you are playing on between 1 and 10 ultimately changing the bet value from 10 to 100 coins is handy for those who like to change the stake during play. The bet placed coincides with the coin value to show the total amount of coins you are able to play with, as the coin value changes between 0.01 and 2.00 the number of coins you have to play also varies. Whilst there is no jackpot in Finn and the Swirly Spin the maximum available win is 500 times your stake in the free spin feature and 420 times in the random feature. To look through the symbol pay out values simply click the information icon to the bottom left of the screen.
