About This Slot

We all know Thunderkick for their highly creative slots output that spans more than half a decade now from their debut release, Esqueleto Explosvio, through high volatility classics like Pink Elephants 1 and 2, Flame Busters and the Beat the Beast series. They are known for producing quirky, fun slots with super-high variance.

For their March 2021 release they once again foray into that territory with this off-beat game that seems to revert to old-skool style graphics whilst shamelessly borrowing from the Megaways™ slot manual – yes, there are even 117,649 ways to win, as well as the usual hectic selection of free spins and mystery wilds … no progressive multipliers though … and a 15,000x + top payout to aim for. Think something of a cross between the classic Fishin’ Frenzy and any of the formulaic Megaways™ games on recent release.

It’s up to you to make up your own mind what you think of that – but what we can tell you is that this game has the potential to tease and deliver big time in equal measure and it’s surely one that any high risk slots fanatic will want to have a crack at. The action starts from just 10p and wins at the base level require just 3 matching symbols on adjacent reels in a classic 4,096 win ways style.

Big Fin Bay is out right now at most UK slot sites.

RTP, Variance and Top Payout

The RTP of Big Fin Bay is set at a pretty average 96.14% which is decent value in the current slots market. However, the gameplay here comes with a warning as it is set to a vertiginous height with a very uneven pay model. You can expect plenty of non-paying action before the reels land in your favour and most of the good stuff is saved for the free spins round where monster wins are triggered by a combination of features aligning.

The top win of 15,040x win is also pretty competitive and matches some of the best high-risk games so far this year, with the exception perhaps of Nolimit City’s more recent efforts like Fire in the Hole.

Symbols and Graphics

The action is Big Fin Bay video slot intitally takes place on a 6×4 grid with 5,040 fixed paylines on which symbols are merely to land on adjacent reels to trigger prizes. The number of win ways can increase right up to the Megaways™-tastic 117,649, but only in the free spins round.

The lower part of the Paytable is taken up with playing card symbols 9 through to Ace that deliver from 0.80x to 1.5x the bet for 6 identical ones a payline. Four Fishing Trophies are premium-paying symbols with prizes of 2x, 2.20x, 3x and 3.20x your stake for 6 of a kind. The Fisherman stands alone as the top-win icon that triggers 7x wins when 6 appear.

Watch out as well for the Golden Swordfish Wild that substitutes all symbols except the Scatter when completing a winning combination. When a Wild does form part of a win then it will expand to cover the whole reel and so potentially create more wins. Finally, there is the scatter, shown as an Anchor, which is needed to trigger the Free Spins round.

What We Like

  Expanding wilds and re-spins
  High top payout
  Good high variance action
  Free spins re-triggers
  Slick design

What We Don't Like

  Variance too high for some

Gameplay and Features

The game has many similarities to Megaways™ in both its expanding reels format and the features. There are no progressive multipliers or cascading wins but you can boost your payouts with a selection of expanding wilds, mystery wilds, free spins and re-spins which all play out as follows:

The Mystery Wild Feature

As well as the expanding wilds, the mystery wild is also avaibable – this Bonus is randomly initiated during main game. Up to 3 whole reels can become covered with Wilds to enhance win potential. No scatters can land in this round.

The Free Spins Feature

When you spot at least 3 Scatters anywhere on the grid, the Free Spins Round is triggered. What’s new and interesting about this Bonus is that each reel on which a Scatter is found awards up to 6 free spins that are added together to create the total number of spins for the round. This way as many as 36 spins can be awarded.

Also, in this round, Wilds always expand to full reel height as well as triggering re-spins. At the same time, an extra wild is added to the wild reel in each case, increasing its size up to a maximum of 7. When a reel hits 7 high, 3 more spins are added to the total.

And of course, if all 6 reels reach 7 rows high, 117, 649 win ways are in action!

Our Verdict

Thunderkick’s latest contribution to the expanding reels genre of slots is a real grower. Initially the look didn’t do it any favours for us – it’s quite basic and old-skool and we started to think this was a quick-release Megaways™ clone. But that is not Thunderkick’s style and they have certainly added their own unique take to this thrilling group of slots. A lot of the good stuff is driven by wilds of course, expanding to enhance wins on regular occasions. But the best bits are in the bonus round where sequences of reel expansion, extra spins and re-spins can really push you onwards towards that 15,040x top payout.
