Our Verdict on Big Bass Bonanza Slot – 7.6/10

After our test, we would first recommend this slot to casual players, due to its medium volatility and 96.71% RTP, that will allow you to place low-risk bets. That said, high-rollers can also enjoy this game with exciting features like the Fisherman Wild that can significantly improve your winnings.

Although it stands out by its variety of winning combinations, 5 reels, and 10 paylines, the game still lacks in a few areas. With a few innovative features, more bonuses, and a few animations to create a lively gameplay, our rating could have gone way up!

How to Play Big Bass Bonanza Slot

In order to enjoy the game to the fullest, you’ll need to understand its mechanics and recognize the symbols that will help you boost your winnings.

Playing Big Bass Bonanza: Step-by-Step Guide

Big Bass Bonanza is a 5×3 reel slot game with 10 different paylines. Its gameplay is quite simple and easy to comprehend. Here’s how a classic game works:

  1. Before your first spin, select the amount of coins you want to bet on each payline and the value of each coin. This will give you the total bet for your next spin. Please keep in mind that the minimum total bet per spin is £0.10, while the maximum is £250.
  2. Spin the wheel and see if you’ve won something.
  3. You can now adjust your bets, benefit from free spins if you were lucky enough to win some, and spin the wheel again.

Big Bass Bonanza Symbols and Features

In the game you’ll find many symbols. Most symbols work the same way: you’ll need to get 3, 4, or 5 of the same one in order to have a winning combination. But each symbol has a different value, so it’s important to identify which ones are the most valuable. 

The first ones are card symbols. There are 5 of those: 10, J, Q, K and A, and are considered low-value symbols. If you get 3, 4, or 5 in a combination, you’ll get up to 10x your bet. Other symbols will boost your winnings even more. 3-5 fish in a combination will get you up to 20x your bet, while 3-5 dragonflies or tackle boxes can multiply it by 50x. 

The two highest value symbols are fishing rods and floats, which can make you win respectively up to 100x and 200x your bet.

Aside from those classic symbols, you’ll be able to find Fish Scatter on your grid. They work the same as the others, but instead of money, they will give you 10, 15 or 20 free spins.

Finally, you might find a last symbol called Fisherman Wild. This one will replace any symbol in order to create a winning combination, but that’s not it. During free spins, the Fisherman Wild will collect all the values of money symbols that appear on the reels during those free spins. If you collect 4 Fishermen, you will get 10 more free spins and unlock a multiplier that will increase every 4 Wilds collected, up to 10x!

Big Bass Bonanza Slot Visuals and Theme

The game shares its visual identity with other games in the Big Bass series, such as Big Bass Splash. In Big Bass Bonanza, you are playing on 5 underwater reels, each one separated by a line of bubbles. In the background you’ll find algae and a deep blue color, and with each of your spins you’ll discover fishing rods, fish, and tackle boxes. While the visuals are polished and aligned with the theme, the game lacks some animation, both in the background and on the reels. Nothing that would get you out of the experience, but it’s always nice when the world enveloping a game seems more alive and immersive.

Regarding the soundtrack, Big Bass Bonanza comes with jolly and catchy music that will probably get stuck in your head for a few minutes after you exit the slot game.

Big Bass Bonanza RTP and Volatility Explained

The RTP (Return to Player) is the percentage of funds you will get back on average when playing a game. Big Bass Bonanza has a 96.71% RTP, which is considered quite high. It means that on average you will get £96.71 back for every £100 you bet. Please note that this percentage is an average, and therefore doesn’t mean you will always get this amount back.

The volatility describes the frequency and nature of the wins you can expect from a slot game. A medium volatility means medium wins at an average frequency. 

The high RTP, combined with medium volatility, ensures you a comfortable experience, during which you shouldn’t be taking too high of a risk but shouldn’t expect to get as many big wins as in a high volatility slot.

Play Big Bass Bonanza Mobile on iOS and Android

With its simple gameplay and visuals, Big Bass Bonanza is perfect for mobile, whether you are on iOS or Android. You won’t even notice the difference between this version and the desktop one: fast loading time, smooth controls, responsive designs, and visuals that don’t suffer from the mobile transition. You can play Big Bass Bonanza on mobile without having to download a new app, directly going to your online casino on your browser.
