Feel the Theme and Graphics of Finn and the Swirly Spin Slot

There is nothing to complain about this game, absolutely nothing. Finn and the Swirly Spins slot features everything you can imagine from the Irish culture: the graphics, the gameplay, the soundtrack, etc. 

Let me start with the cartoon theme. All the icons in this game are related to Irish folklore: from the leprechaun tootling on the side to the rainbow spreading across the sky at the back, even the playing symbols are from their belief in luck. You couldn’t help but feel the Irish beauty radiating out of this slot game.

The graphics and music are also wonderful. All of them are made in 3D slots with one of the finest qualities that I have ever seen in all the games I played. The tree blowing with the wind in the background really highlights the whole picture, as it moves faster and faster each time the key gets closer to the keyhole. Every time there is a big win, the screen shakes up, the leprechaun will play the flute quicker and leaves fall all over the place. How can you not fall in love with those little but charming details?

RTP, Variance & Technical Data

In this section, I’m going to reveal some relevant data about this game, including RTP, volatility, payout, paytable, etc. Without further ado, let’s get started.

Return to Player and Variance

This NetEnt slot has an RTP of 96.62%, slightly above the industry average. With a low to med volatility, this slot is suitable for most players, as the payouts are pretty frequent. But for those who love big wins and long for some serious excitement, this game may not be their preferred choice as the payouts are really low in value. 

Betting Range

The line bet can be changed between 0.01 and 2.00, which are somewhat standard for slot games nowadays. The bet level can also be adjusted between 1 and 10, making the total bet vary from $0.1 to $200. The betting range is set up like this so that it can fit the preference of most gamblers.

Paylines and Highest Payout

Finn and the Swirly Spin slot is a fairly strange slot game with a unique layout. It follows a swirling pattern, which means that there is only 1 reel theoretically. There is also no pay line in this game, as every 3 similar symbols standing next to each other in a row or column will trigger a win. The highest payout, therefore, is low as well (only 500 times your stake for 5 identical symbols).


The payout of this game is described as below:

  • The Diamond: Pays 500 times for 5 on the same line
  • The Hazelnut: Pays 120 times for 5 on the same line
  • The Horseshoe: Pays 100 times for 5 on the same line
  • The Clover: Pays 80 times for 5 on the same line
  • The Heart and the Spade: Pay 40 times for 5 on the same line

Since it’s very common to get a winning combination in this slot, the payout values must below as well.

Where Can You Play for Free?

How to Play Finn and the Swirly Spin?

The gameplay in this slot game is identical to most of the slots from NetEnt, so I will explain this section briefly for you:

  1. The center of the options bar is the Spin button. Pressing this button will spin the reel, or roll the pattern in this case. You can press on the screen to skip the animation and save time.
  2. On the left of the Spin button is the Autoplay function. The number of auto spins can be chosen from 10 to 1000.
  3. On the right of the Spin button is the Max bet. Pressing Max bet will automatically set the betting level to 10.
  4. Next to the Autoplay button, on the left is the Bet level, changeable from 1 to 10.
  5. The Coin value on the right of the Max bet is used to set your preferable stake.
  6. The small box above the Coin value shows the number of keys that you have collected during this session.

In-Game Bonus Features

Here comes the highlights of the show. All the features of this famous slot harmonize perfectly with each other, and there are at least 7 of them! I will categorize them into 5 groups and explain them clearly in this section.

Avalanche Feature

Every winning combination will be destroyed after calculating the payout, and those blocks will be replaced by the next symbol in-line. 

Wild Feature

This game does come with the Wild function, which symbolizes the shape of a star. Wild symbols appear when there is a winning combo with 3 or more similar figures (combo with Wild itself does not create another Wild). After the Wild symbol is triggered, it will explode and destroy 4 adjacent blocks.

Sticky Wild Feature

The Sticky Wild can only appear during the Lava Lair Free Spins. It functions the same as a regular Wild symbol, except that it cannot be destroyed and cannot destroy blocks around it.

Random Features

One main attraction of the game is the Random features, which can be triggered when you least expect them. There are four types of Random:

  • Starfall Wilds: When it happens, 2 or more Wild symbols will pop out and replace the blocks on the screen. If there is no winning combo afterward, another Wild will appear until at least 1 win is realized.
  • Dragon Destroy: This Random can only be triggered if there is no winning combination on the screen beforehand. Dragon Destroy will randomly destroy a number of symbols to create the avalanche effect. It is created to ensure that a win is guaranteed after the avalanche.
  • Irish Luck: The condition is the same as Dragon Destroy. A horizontal or vertical type of symbol (except Wild) is added to the reel, giving a guaranteed win.
  • Magic Transform: This Random will transform all Heart and Spade symbols into a higher-paying one. The potential wins of this feature are great, however, there is no condition required.
    Free Spins Bonuses

The other charm of this slot is the Free Spins Bonuses. There are four types of Free Spins in correspondence with the Random Features. But first, you need to collect the keys by sending them to the center through avalanches. Each Free Spins game will need a certain amount of keys, from 1 to 16. I have to warn you, that getting keys is a painful and frustrating process, but the rewards are so satisfying.

  • The Star Bar: Requires 1 key to unlock. You will be awarded 7 free spins, each one will feature the Starfall Wilds Random.
  • The Lava Lair: Requires 4 keys to unlock. You will get 3 free spins, together with the Sticky Wild and Dragon Destroy activated.
  • Lucky Mug: Requires 9 keys to unlock. It features the Irish Luck and has 4 free spins each round.
  • Golden Pot: Requires 16 keys to unlock. There are only 2 free rounds in this game and it features the Magic Transform Random.

If you have played the Finn and the Swirly Spin demo version on our page, you will soon realize it is almost impossible to get to the last game. You may have to spend all your luck and effort on this slot, but the payoff will be so worth it.

Expert Verdict

Will there be a sack full of gold at the end of that rainbow? Hopefully. This slot has shown the true potential of NetEnt, one of the greatest gaming providers in the world. The gameplay, the graphics, the music, are all so marvelous and fascinating that will keep you entertained for hour after hour. I recommend all readers to give this slot game a shot, for Finn and the Swirly Spin may be one of the best NetEnt games for years to come.
