Big Bass Bonanza Megaways Slot Review

Big Bass Bonanza Megaways is taking the classic fishing experience and shaking it up with the Megaways mechanics, throwing in a whole bunch of bonus features and a pretty crazy ride when it comes to volatility. Let’s take a closer look at how this slot game actually plays, what you can expect to win, and what you’re really getting yourself into when you spin the reels.

Slot Provider

Big Bass Bonanza Megaways is a high-octane slot game, created by Pragmatic Play and Reel Kingdom, a company known for offering feature-rich slot games, clear RTP levels, and great performance on all devices.

Slot Theme and Story Line

The slot theme is fishing, and to be honest, it lacks anything much of a storyline. You’ll be transported to a peaceful lake, with reels filled with fishermen, fish, and cash symbols. 

Reels, Rows, Paylines

Big Bass Bonanza Megaways plays out on six reels, with the number of rows on the reels varying with each spin. The number of symbols on the reels can be anywhere between 2 and 7, and there’s a maximum of 46,656 ways.

RTP & Volatility

Big Bass Bonanza Megaways RTP is 96.70%, and it is highly volatile. You’ll encounter a few dry spells, but when the bonus feature drops in, the rewards can be huge.

Betting Range

Bets start at £0.20 and go up to £100 per spin. Keep an eye on your bankroll, as the volatility of the game can change pretty quickly.

Max Win Potential

You can win up to 4,000x your stake. While this is decent, let’s be honest, Big Bass Bonanza Megaways is pretty much middle of the road when it comes to the max win potential.

Jackpot Element

No jackpot is present. If you see the term “jackpot race,” this simply refers to the total amount of wins you earn through the features.

Graphics & Sound

The graphics are quite nice, with bright and clear visuals. The sound is pretty relaxed and repetitive, which actually works quite well if you are playing the game for a long time.

Pros and Cons

Of course, no game is perfect, and all games have their advantages and disadvantages. Below are the pros and cons that I discovered after testing the Big Bass Bonanza Megaways game:

Pros

  • Higher RTP than most Megaways slots.  

  • Familiar gameplay.

  • Lots of bonus features and free spins.

  • Good betting options

Cons

  • High volatility doesn’t suit all players.  

  • Max win is low compared to other Megaways titles.

Game Symbols and Payouts

Big Bass Bonanza Megaways doesn’t overcomplicate things with symbols. Here’s what I found during testing:

Special Symbols

The wild symbols replace all symbols except scatter symbols. The scatter symbols appear on the base reels and trigger the free spins feature. The money symbols show cash amounts, and the fisherman collects them during the bonus games.

Regular Symbols

The lower-paying symbols include the card ranks, while the higher-value symbols include fish and fishing equipment. The winning combinations increase according to the reels on which the symbols appear.

Big Bass Bonanza Megaways Demo Version and Free Play

There’s also a demo version of the Big Bass Bonanza Megaways slot game, which can be found at many online casinos that are licensed in the UK. 

With this version, you can play the game without risk, spinning the reels with virtual money. This is especially useful since the game has high volatility, meaning that you may not win anything over a long stretch of spins. 

Playing the game in the demo version will give you the insight you need into how the Megaways reels function, how the free spins feature is triggered, and how the fisherman collection feature improves throughout the game.

Big Bass Bonanza Megaways Bonus and Key Features

Big Bass Bonanza Megaways is a game that is centred on feature-rich gameplay, with most of its winning potential coming from free spins and progressive bonus features rather than the main game itself. It is essential to understand how these features work.

Free Spins Feature

When three or more scatter symbols appear, the free spins feature is triggered. In the free spins feature, the Money symbols fall to the bottom of the reels, rather than vanishing.

Special Features

Fisherman symbols collect all the Money symbols on the reels. Every four Fishermen collect, the free spins feature is retriggered, and the win multiplier increases from 2x to 3x, then to 10x. Dynamite and Bazooka features may be triggered randomly.

Mobile Play Experience

Big Bass Bonanza Megaways is compatible with iPhone and Android devices.
The mobile version is well-designed, allowing you to adjust your bet or spin the reels in just one tap. 
Big Bass Bonanza Megaways plays well in portrait mode, and I didn’t experience any lag or connection drops, even when there were numerous cascading wins.

Big Bass Bonanza Megaways Expert Tips & Strategies 

As a high-volatility Megaways slot, it is essential to get a feel for the game’s tempo before investing real cash. 

Begin with the demo game to understand how the free spins bonus is triggered and where the key winning potential lies. 

When playing with real cash, it is essential to keep bets low to maximise playtime.
The free spins bonus rounds, particularly after unlocking additional bonuses, hold the key to winning potential.

SportsBoom Suggests – Is Big Bass Bonanza Megaways Worth Playing?

Big Bass Bonanza Megaways is best suited for UK players who are comfortable with highly volatile games that derive most of their value from feature-based payouts. There is a very long dry spell, and it is essential to be patient and have your bankroll under control. 

It is highly recommended to start your journey on Big Bass Bonanza Megaways in demo mode first to understand the value of the Megaways engine and the free spin upgrades. When you decide to play for real money, it is essential to keep your bets low, especially during base game play. It is recommended to increase your bet only when you start receiving more frequent bonus features.

FAQs

Can I play Big Bass Bonanza Megaways in the UK?

Absolutely. You can find Big Bass Bonanza Megaways at online casinos that are licensed by the UK Gambling Commission, and therefore, there is no need to worry about the legality and security of the game. The UK version has local regulations, which include responsible gambling, betting limits, and the features that can be used.

What’s the RTP and volatility like?

This slot gives you an RTP of 96.70%, which stacks up well against other Megaways games. It’s a high-volatility slot, so don’t expect wins to land often. Most of the serious payout action happens in the bonus features, not the base game.

How much can I win?

You can win up to 4,000 times your stake. Sure, that’s lower than some other Megaways slots, but it still packs a punch, especially if you manage to unlock all the free spins upgrades.

How do the bonus features work?

If you want to reach the bonus games, you’ll need to get some scatter symbols. That gives you the free spins. In these spins, the Fisherman symbols collect all the Money symbols and add the amounts to your win. More features mean that the multipliers start increasing, which is good for your win.

What’s the betting range?

You can wager anywhere from 20p to £100 on a single spin. It’s open to just about anyone, whether you’re betting low and slow or going high-roller-style. Because this game is pretty volatile, it’s probably smart to stick with smaller wagers.

Is there a progressive jackpot?

Nope. There’s no progressive jackpot in Big Bass Bonanza Megaways. All your wins come from the regular game and bonus features.

Any tips for playing this slot in the UK?

Definitely. First, try the demo mode to get a feel for how the game plays and how the bonuses trigger. Keep an eye on your bankroll, play low bets, and try to trigger the free spins. Most of the real win potential is in the free spins bonus rounds, not in the main game.
