Finn and the Swirly Spin Slot Review

Finn and the Swirly Spin Slot Review

Gameplay**

Finn and the Swirly Spin is a unique slot game that plays on a five-by-five grid, where wins are awarded for lines of three to five symbols along horizontal and vertical lines. Instead of spinning reels, symbols appear at random on the grid (except for the Key symbol which appears in the bottom left).

The interesting part begins when winning symbols are exploded and a cascade mechanic kicks in. Unlike other cascade mechanics where symbols fall from the top, in this game, symbols are loaded in from the bottom left and move around in a spiral towards the center of the grid.

If you're lucky, the Key symbol will travel all the way to the middle of the swirl and trigger free spins. When the Key symbol makes it around from the bottom left to the center, one of four bonus games can be triggered (see below for details).

Wilds, Bonuses, and Free Spins

There are several random bonus features that can be rewarded at random after a spin:

  1. Starfall Wilds: Two or more Wild symbols are added to the grid until there is no win.
  2. Dragon Destroy: A random number of symbols are destroyed, always resulting in a win.
  3. Irish Luck: A horizontal or vertical line of one symbol is added to create a win for the player.
  4. Magic Transform: All Spade and Heart symbols are transformed into a random higher-paying symbol.

Dragon Destroy and Irish Luck only occur when there are no wins on a spin.

Wild symbols have a unique behavior in this game. They substitute for any symbol as usual, but they appear only when a win occurs without a Wild symbol. When the winning symbols explode, one will be replaced by a Wild symbol.

When a win involves a Wild symbol, it destroys any other symbols horizontally or vertically adjacent to it. No new Wild is generated by this kind of win.

Free Spins

During Lava Lair free spins, there is a sticky Wild symbol that remains in place as the other symbols spiral towards the middle. If enough symbols are destroyed to move the Key symbol round to the middle of the dial, you unlock a bonus round.

Initially, you can only unlock the basic free spin game, but each time you trigger the bonus, you gain a key, eventually unlocking all four. These four free spin games provide you with a number of free spins and an additional feature. The feature and number of spins are different for each of the bonus games.

Bet Sizes, RTP, and Variance

Finn and the Swirly Spin has a slightly above average return to player (RTP) of 96.62% and low to medium volatility. While the RTP is acceptable, we usually prefer high volatility slots that work better with our strategies.

The maximum bet per swirl was £/$/€0.10 on the site we tested, and the maximum bet was £/$/€200.


This is a lovely slot absolutely jam-packed with cool features and design. The random bonuses are a fun little spice, and the longer-term process of unlocking the free spin bonuses is rewarding and gives the game continuity between spins.

Its only major detraction is the low variance, which we would prefer to be much higher.

Overall, Finn and the Swirly Spin is a strong slot that is a lot of fun to play.
