    About Finn and the Swirly Spin

    Finn and the Swirly Spin is a 5 reel, 5-row video slot game which works in a 5×5 clockwise grid form. It swirls around your screen rather than falling and landing as a standard slot game would offer.

    With up to 10 pay lines available at any one time, there is always more to come in the same spin thanks to its style, similar to cascading.

    The Key is, well, key to this video slot game. Locked in a frozen block of crystal-like ice at the bottom left of your play screen at the start of each spin. It needs to reach the lock at the centre of the grid wherein the bonus round spins can begin. The aim of Finn and the Swirly Spin is to clear the path by smashing win lines on the way, moving the much-needed key further around the swirl to its destiny!

    Finn and the Swirly Spin Graphics Design

    As is typical with most video slots these days, Finn and the Swirly Spin doesn’t disappoint in terms of graphics or design. With blinking stars; a dancing leprechaun; various bonus types (yes there are 4 to choose from!) and not forgetting the random feature awards, there is always something to make you feel like you’re a part of Finn’s journey.

    Enjoy Finn and the Swirly Spin with musical melodies and sounds, or without. The choice is yours to make as either option is available and won’t affect the gameplay

    How to Play Finn and the Swirly Spin

    Really rather simply, all you need to do is select the bet amount and hit spin. There is no complication such as choosing an amount per line or however many lines you wish to play. Just choose the amount that you would wish to play each spin at and go. Simple as that!

    What Symbol Triggers the Finn and the Swirly Spin Slot Bonus Free Spins?

    The unique game has a different style of free spins feature. Collect the key symbol and get onto the free spins. You will be able to unlock one of four different bonus game options. Continue reading for more details on these bonus rounds and the free spins feature.

    Interactive Features

    First off you will notice that frozen block containing the key that I mentioned earlier, it starts in the bottom left of your grid.  Keep an eye on that glistening key as it holds the way into a magical world brimming with free spin bonuses in different mystical lands. That key can only move around the grid once the symbols in its way on the path are gone.

    There are no wilds in the initial spin (which I’m now going to call a swirl as it is more apt for this video slot game). This is because wilds are created by winning lines. They take the form of a blinking star that will stay in your grid throughout the swirl’s entirety, until used in another winning pay line or until all possible wins are exhausted.

    Once you have a wild that is included in another win line, it will also blast one or two of its neighbouring symbols. This brings the key to the bonus world ever closer to the centre of the grid.

    The symbols you will see are black spades, wooden hearts, horseshoes, acorns, clovers and pink diamonds. Pink diamond lines offer the highest return.

    As there are randomly awarded features as well as bonuses, there’s a lot to talk about here. Let’s start with the bonus rounds.

    Bonus Round Choices

    Once the magical world is unlocked there are several options you can choose from. Take note that only one option is available when you first play. The more you play Finn and the Swirly Spin, the more keys you will win and in turn, the more bonus worlds you can unlock. They are as follows:

    Star Bar (1 key to unlock)

    This bonus round offers 7 free swirl’s (spins). With each spin comes at least 2 guaranteed wild to be shot out into your grid. Up to 5 wilds can be shot out during each free spin.

    Lava Lair (4 keys to unlock)

    This selected bonus round offers 3 free swirls. It also features a coin in the bottom left of your screen, in place of the key encased in ice you originally see in normal gameplay. This coin acts as a wild throughout each spin.

    Once the initial spin has laid out the symbols (and any wins have already been exhausted) a dragon on your screen will shoot random symbols down with fire. This means the coin is moving closer to the centre of the grid. This is where your bigger wins will come from as the wild is more likely to be within a win line the closer it is to the centre. The coin will also never disappear during these rounds meaning you have a constant wild throughout gameplay in this bonus round!

    Lucky Mug (9 keys to unlock)

    This bonus round choice offers 4 free swirls and is the only bonus feature that will absolutely guarantee a win. Each spin enjoys an animated beer-mug ‘cheers’ over the top of the grid, which spills out one win line of identical symbols.

    Golden Pot (16 keys to unlock)

    These bonus round choices offer the fewest free spins of 2, however, it has the potential to bring you a greater win should it be your lucky day! The lucky pot at the end of the rainbow, showers your grid with luck. This turns lower payout symbols that have been laid on your free swirl into higher payout symbols. Not once, but twice!

    So all black spades will transform, and all wooden heart will transform too. Once any win line has been created, the blinking star wilds are activated in their place meaning a further greater chance of a win line again. 2 free spins might not sound a lot, but they can last a while if you hit lots of constantly avalanching win lines.

    At any given time, on any stake played, Finn can decide to give you a random feature which is essentially one go of any of the bonus rounds. They come with the following names:

    •       Starfall Wilds (as featured in Star Bar)
    •       Dragon Destroy (as featured in Lava Lair)
    •       Irish Luck (as featured in Lucky Mug)
    •       Magic Transform (as featured in Golden Pot)

    Only two of these will guarantee you a win. The Lucky Mug, as it will instantly transform any random line from their current symbols to matching symbols thus giving a winning pay line. Also, Star Bar, as it will shoot from 2 stars up to 5 until there is a win. The others will simply enhance your chances of a win. Look out for key symbols, heart symbols and bonus features.

    There are no scatter wins available in Finn and the Swirly Spin but then again, there’s barely any room for more ways to win so it is not to the game’s detriment!

    Paylines and Stakes

    Finn and the Swirly Spin offers cluster pays on any one swirl I.e. full screen. With a vast number of potential wins, before the frozen key reaches its destiny for the bonus rounds, it brings a countless number of full-screen swirls and movements within that initial spin. This means the pay lines offering is much more than 10 with any one staked game. You can match symbols in a vertical line or any other combo.

    You can bet from as little as 0.10 per game right up to a mega 200.00 per game. Whilst the bonus and random features can happen on any stake. Hit a bonus or random feature on the higher staked games and you could be sitting high upon that rainbow with Finn and his pot of gold himself!

    Symbol payout values are as follows:

    Wooden Heart & Black Spade

    • 3 in a line = 1 coin (0.1% of stake)
    • 4 in a line = 10 coins (1x stake)
    • 5 in a line = 40 coins (4x stake)

    Lucky 4 Leaf Clover

    • 3 in a line = 10 coins (1x stake)
    • 4 in a line = 30 coins (3x stake)
    • 5 in a line = 80 coins (8x stake)

    Lucky Horseshoe

    • 3 in a line = 10 coins (1x stake)
    • 4 in a line = 40 coins (4x stake)
    • 5 in a line = 100 coins (10x stake)


    • 3 in a line = 10 coins (1x stake)
    • 4 in a line = 50 coins (5x stake)
    • 5 in a line = 120 coins (12x stake)

    Pink Diamond

    • 3 in a line = 20 coins (1x stake)
    • 4 in a line = 100 coins (10x stake)
    • 5 in a line = 500 coins (50x stake)

    Wild stars cannot replace the frozen key at any time during normal gameplay. Plus the frozen key cannot be eliminated from the swirl during normal gameplay either until it reaches the centre of the grid that is!
