Should I Choose Big Fin Bay Free or Real Money Play?

Big Fin Bay free play sounds attractive because it allows you to relax and savour the game without risking an actual investment. You place your wagers in virtual coins and play for the sheer sake of it. In contrast, real money wagering requires you to take a risk to make some actual profit. Therefore, when choosing between Big Fin Bay free and real money play, you need to consider the type of reward you are looking to receive from this particular slot. If your goal is pure gaming satisfaction, then you should consider the first approach.

Big Fin Bay Rules: Kickstart Your Play

Learning the basic Big Fin Bay rules and settings, which are pretty straightforward, will give you a better chance at pursuing satisfying gameplay and big wins. The base Big Fin Bay game has 6 reels containing between 2 and 7 symbols. However, once you trigger the free spins feature, the game expands to 6×7 reels and 117,649 payways. Talking about free spins, according to Big Fin Bay’s rules, you need to land 3 to 6 Anchor scatter symbols to utilize this feature. You should also pay attention to the Golden Merlin wild symbol, which serves as an excellent replacement to create new winning combinations. Mystery Wilds are another impressive feature, which allows you to turn up to 3 regular reels into full wilds.

Big Fin Bay Winning Symbols: Learn the Basics

Big Fin Bay winning symbols are nicely crafted and straightforward. As with any other slot, getting to know the symbols’ meaning is of primary importance for player success. Therefore, we will give you a comprehensive overview of the Big Fin Bay symbols, which we have divided into three categories for your convenience. Additionally, you have the scatter symbol, an anchor, and the wild, represented by a golden merlin.

Low-Paying Symbols


The low-paying Big Fin Bay symbols comprise the 9-A classic card deck. They are brightly coloured and enjoyable, although not entirely in sync with the slot’s seaside theme.

Medium-Paying Symbols


Four funny fish represent the medium-paying Big Fin Bay symbols in red, blue, green, and purple.

High-Paying Symbols


The highest-paying Big Fin Bay symbol is The Captain. The suntanned bearded man smoking a pipe looks like a seasoned fisherman who will expertly guide you to a big win.

Enjoy a Fascinating Sea Adventure with the Diverse Big Fin Bay Features

Big Fin Bay features are extremely well-thought and diverse, creating unique gameplay for everyone who enjoys sea fishing and seeks exciting rewards. You have the lucrative Mystery Wild and Expanding Wilds and the Bonus Game, which is reasonably lavish on free spins. Read below for a detailed description of each Big Fin Bay feature.

Mystery Wild

The Mystery Wild feature is a great way to form winning combinations. The Mystery Wild symbols appear randomly during your game and can turn up to 3 reels into full wilds. Note, however, that the scatter symbol is disabled while this feature is on.

Expanding Wilds

You can activate the Expanding Wilds feature when you land a wild in a winning combination. The idea is that the wild will expand to fill the entire reel and enhance the probability of hitting a winning combo.

Bonus Game Feature

Big Fin Bay’s Bonus Game feature is skillfully crafted for your maximum enjoyment and success. Landing 3+ Anchor scatter symbols triggers this feature, which can award you with as many as 36 spins at the start. Further, each wild expands to turn the reel into a full wild, rewards a respin, and lengthens the reel by adding more symbols. All of these functions serve to increase your winning potential.

Big Fin Bay Graphics and Design: Charming Retro Fishing Trip

Big Fin Bay graphics and design are impressive with their fantastic attention to detail. The overall feel features retro coastal charm and a cosy atmosphere. The images are slightly cartoonish and cheerful, thus raising your spirit and preparing you for a thrilling adventure. Big Fin Bay graphics highlight bright and jolly symbols against a bluish coastal backdrop that covers in a lovely pink at sunset. In the distance behind the reels, you can see the Big Fin Bay itself, which – we must admit – looks very inviting. The designers have gone for a clear-cut, uncluttered look. The coastal colour palette paints a beautiful seaside picture and creates a sense of calm.

The slot’s lower-value symbols are the classic A to 9 royals. Surprisingly, the designers have chosen not to stylize them according to the game’s theme. The medium-value symbols are represented as fish. The highest-paying symbol is a jolly fisherman, also called “The Captain.” The scatter symbol is an anchor, and the wild depicts a golden marlin. Generally, Big Fin Bay’s graphics and design look very inviting and create a pleasantly relaxed feeling. The colour palette is vibrant, with a typical coastal touch and a hint of adventure. The music is lovely and fits the game’s overall theme.

Big Fin Bay’s Creators Thunderkick: Outstanding Graphics and Enticing Gameplay

Created in 2012 in a tiny Stockholm studio, Thunderkick’s mission is to conquer an industry ruled by giants through state-of-the-art graphics and revolutionary slot ideas.

Thunderkick slots are famous for their fascinating design and exciting gameplay.

It is worth mentioning that Thunderkick’s entire game and platform development is performed within the 50-employee company’s powerhouse. Such an approach allows Thunderkick casinos to be flexible and adaptable to the industry demands. Talking about the gaming world in general, it would be nice to see live dealer and more table game slots from Thunderkick. The game studio has demonstrated outstanding work so far, and we expect plenty of world-class additions to its portfolio.

What Is Big Fin Bay’s RTP?

Big Fin Bay’s RTP is around the industry’s average with 96.14%. Return to Player (RTP) is the term that represents the percentage of wagered money that a game will pay you back over time. There are two ways to calculate a slot’s RTP – a theoretical and a simulated approach. The industry’s standards on fair play require game providers like Thunderkick casinos to announce their RTPs. However, beware that a game’s RTP can vary according to the specific online casino. Therefore, always make sure to check RTPs when wagering real money. Big Fin Bay’s RTP of 96.14%, coupled with high variance, means that the slot allows you to win big although less frequent profits. In general, Thunderkick casinos display RTPs around the industry’s average with one huge exception: 1429 Uncharted Seas, which is also a maritime-themed slot, has the outstanding 98.5% RTP.
