Where to Play Big Bass Bonanza Megaways
Big Bass Bonanza Megaways RTP and Wagering
Big Bass Bonanza Megaways is a 6-reel, 2-6 row slot game featuring up to 46,656 ways to win with the Megaways mechanics, developed in partnership with Reel Kingdom. Over time, the Big Bass series has evolved from a Fishin’ Frenzy knockoff to one of the most well-known fishing-collection games and this particular slot game has been instrumental for that journey.
The number of symbols on each reel can vary, creating a dynamic and ever-changing play area. The wagering range allows for flexibility, with stakes starting at £0.20 per spin and going up to £100 per spin (all stakes limited to £5 per spin for UKGC-based casinos).
The game has the Megaways mechanic but differs from it slightly. Typically, you get up to seven rows in Megaways games (a changing number of rows/symbols). Big Bass Bonanza Megaways only goes up to five.
At a glance, this means you get fewer winning formations. But the game’s base RTP is higher than Megaways slots at an impressive 96.7%. This more than makes up for the lost lines because as a high-volatility slot, you will be getting more money back over the long run with cascading reels and free spin rounds—which, in turn, trigger with three Scatter symbols, not four—making it a very interesting game.
The max win in Big Bass Bonanza Megaways is 4,000x your stake, which can be achieved through the Money Symbols and multipliers during the Free Spins round. This is low compared to popular fishing slots, Pragmatic Play’s next Big Bass slots, and many other Megaways slots in general.
Big Bass Bonanza Megaways Symbols and Audio & Video Design
Big Bass Bonanza Megaways features a fun, fishing-themed design based on the simplicity of the Big Bass games (not Bigger Bass). Complete with colourful fishes and aquatic plants, the reels are set amid the deep blue sea under a bright, sunlit ocean surface. The lively soundtrack, with cheerful tunes and the occasional seagull squawking, adds to the light-hearted fishing adventure vibe.
There are several key symbols in the game, including premium fish-related symbols and the iconic fisherman. The Wild symbol is represented by a fishing net and substitutes for all symbols except the scatter and fisherman. The Scatter symbol is a fish jumping out of the water and triggers the Free Spins feature when three or more land on the reels.

Big Bass Bonanza Megaways Mobile Features
Pragmatic Play is well-known to develop mobile-friendly slot games. Big Bass Bonanza Megaways is a good example of how to create an HTML5 slot game that works really well on mobile. It is snappy, offers easy-to-use controls, and a neatly laid out grid.
Big Bass Bonanza Megaways Bonus Features
Multiple bonus features in the game can significantly boost your chances of big wins. Combining wilds, money symbols, and free spins, this slot keeps the action flowing. Let us break these features down:
Free Spins Feature
To trigger the Free Spins round, you need to land 3, 4, 5, or 6 Scatter symbols (the fish jumping out of the water) anywhere on the reels. This grants you 10, 15, 20, or 25 free spins, respectively. During the Free Spins, the Fisherman symbol appears on all reels. Every time he lands, he collects all values from the Money symbols (the fish symbols). Collecting 4 Fisherman symbols in the metre retriggers the feature and adds 10 more free spins with an increasing multiplier (2x, 3x, and 10x for each retrigger). The Dynamite and Bazooka features can also activate randomly to add more Money symbols or create winning combinations.
Dynamite Feature
The Dynamite feature can trigger randomly during the Free Spins round if there are 1 or 2 Fisherman symbols on the reels and no Money symbols in view. When activated, the Dynamite feature adds Money symbols to the reels in random positions, increasing your chances of collecting higher values with the Fisherman symbol.
Bazooka Feature
Another random feature, the Bazooka, can trigger when there are 1 or 2 Fisherman symbols but no Money symbols. When the Bazooka activates, all symbols (except the Fisherman) are destroyed, giving you a guaranteed win by clearing the reels and potentially leading to higher payouts.
Big Bass Bonanza Megaways Final Thoughts
96.7% RTP, a wide betting range of up to £100 (on UKGC casinos you are hard-capped at just £5), cascading/tumbling symbols, Megaways, and free spin retriggers that can go up to 10x your wager all make Big Bass Bonanza Megaways an excellent slot game by all means. Add to that a fun symbol collection mechanic and an interesting underwater/fishing theme and you have one of the most popular and greatest slots by Pragmatic Play. The only thing keeping it back is the subpar 4,000x max win potential given its high volatility.
The game is developed in partnership with Reel Kingdom.
Rating: 9 (Exceptional)
They have taken the Megaways concept and made it quite interesting. You trigger the free spins with 3 Scatters, not 4. And you have a higher base RTP alongside the very high volatility at the expense of 2-5 additional rows vs. 2-7 additional rows in a typical Megaways slot game. These tweaks look small on paper, but have a profound impact on the gameplay. Big Bass Bonanza Megaways is as good as slot games get, and deserves all the popularity it gets. But of course, there is also the Big Bass Hold & Spinner Megaways—Pragmatic Play’s next Megaways engine incorporating a Big Bass game that has even more bonuses and a 20,000x max payout potential.
That is the only thing keeping me from rating Big Bass Bonanza Megaways 10/10. Oh, and the fact that Bigger Bass Bonanza has flashier graphics, and developing a game in the Big Bass style while you already have Bigger Bass Bonanza available is a questionable decision.
