Big Bass Bonanza Megaways Slot Review 2026
Overview
Pragmatic Play takes the Big Bass franchise to Megaways: 96.71% RTP, high volatility, up to 200,704 ways across 6 reels, and a free spins round where money symbols and a running multiplier can combine for the 4,000x ceiling.
Big Bass Bonanza Megaways improves on the original's free spins format and layers it onto a proper Megaways engine. The money symbol mechanic from Big Bass Bonanza works better with the variable win-ways structure — a big money symbol cluster during free spins paired with a high running multiplier is one of the more satisfying hits in the franchise. Solid execution, 96.71% RTP, and 4,000x ceiling that's reachable on a strong bonus round.

Full Review
Big Bass Bonanza Megaways is a Megaways slot from Pragmatic Play that takes the studio’s popular fishing franchise and runs it through the BTG-licensed Megaways engine. The result is a game where the number of active ways to win changes on every single spin, the six reels each display a random number of rows per spin, and the total ways to win can reach up to 117,649 on any given spin. The RTP is 96.08%, which sits comfortably in line with modern high-volatility Megaways titles. If you know the original Big Bass Bonanza, this version keeps everything that made it work, the Fisherman Wilds, the cascading wins, the fishing rod scatters, and pairs it with the Megaways mechanic’s variable reel height for a substantially bigger win ceiling.
The defining feature here is the Fisherman Wild, and I think it’s one of the more inventive wild implementations in the Megaways category. Standard wilds substitute for symbols. The Fisherman Wild does that too, but it also collects fish symbols it encounters during a tumble sequence, accumulating a prize value with each fish it picks up. When the tumble sequence ends, the Fisherman pays out everything it has collected. That means a single Fisherman landing at the start of a long cascade chain can deliver a win that grows substantially with every tumble, a mechanic that creates genuine anticipation across the sequence rather than resolving instantly.
How Big Bass Bonanza Megaways Plays
The game runs on six reels. On each spin, every reel independently displays between two and seven rows of symbols, so the total number of active ways to win changes with every spin. At maximum reel height across all six reels, you get 117,649 ways. Most spins will produce far fewer ways than that, but when the reels stack high, the grid expands noticeably. Wins are formed by landing matching symbols on adjacent reels starting from the leftmost reel, with a minimum of two matching symbols on consecutive reels required for smaller wins and three or more for the main paytable prizes.
After a winning combination lands, the cascade mechanic activates: winning symbols disappear from the reels, and the symbols above them fall down to fill the gaps. New symbols then drop in from the top to fill remaining empty positions. If that creates another winning combination, the process repeats. Cascades continue until no new win forms. This tumble sequence is what makes the Fisherman Wild so valuable, each cascade gives the Fisherman another opportunity to collect fish symbols and add to its prize total.
Bets run from €0.20 minimum to €100 maximum per spin. The premium symbols in the game are the fishing-themed characters, the angler himself at the top of the paytable, followed by boots, fishing rods, and tackle boxes representing mid-range value. Low-value symbols are the standard A, K, Q, J card royals. The Fisherman Wild substitutes for all paying symbols except scatters.
Features & Free Spins
The Fisherman Wild is the centrepiece of this game’s feature set. When a Fisherman Wild lands on the reels, it functions as a standard wild (substituting for paying symbols) and simultaneously begins collecting fish symbols. Every fish symbol that appears anywhere on the grid during the same spin and subsequent cascades adds a monetary prize value to the Fisherman’s counter, you can see this value displayed on the wild itself. At the conclusion of the entire tumble sequence, the Fisherman pays out the total accumulated fish value as a cash prize on top of any line wins.
The implication is that a Fisherman Wild landing on the first tumble of a long cascade chain is worth far more than one that appears on the final tumble. Each cascade refreshes the grid with new symbols, each of which has a chance to be a fish, so a chain of six or seven cascades with an active Fisherman can produce a prize value that dwarfs the line wins. During free spins, this effect is amplified because the probability of triggering cascades increases with the free spins mechanics, and the fish values that drop can be large.
Free spins are triggered by landing four or more fishing rod scatter symbols anywhere on the reels in a single spin. Four scatters award 10 free spins. Landing additional scatters during the feature triggers a retrigger, adding more spins to the count. During the free spins round, the Fisherman Wild operates exactly as in the base game, collecting fish and paying the accumulated total at the end of each tumble sequence. The difference is that free spins tend to produce more cascades and more Fisherman Wild appearances, which is where the game’s 15,000x maximum win potential concentrates.
RTP, Volatility & Max Win
Big Bass Bonanza Megaways runs at 96.08% RTP. That figure comes from Pragmatic Play’s official documentation and is in line with the typical range for high-volatility Megaways titles. High volatility here is genuine, base game spins can pass without any meaningful wins for extended periods, and the game’s math is designed for the free spins round to carry the bulk of win distribution. For session play, this means budgeting for enough spins to reasonably expect one or more free spins triggers. At €0.20 minimum bet, 200 spins costs €40, a workable test window before expecting feature hits.
The maximum win is 15,000x the stake. Achieving it requires a combination of maximum Megaways (all reels at full height simultaneously) and a long cascade chain during free spins with multiple Fisherman Wilds collecting large fish values. It is a genuine ceiling rather than a regularly approached outcome. For practical planning: a 50x win from a single free spins round is a strong result; 200x+ represents a top-tier session. The max win of 15,000x at maximum bet of €100 equals €1,500,000, a theoretical figure that requires every condition to align.
Where to Play Big Bass Bonanza Megaways
Big Bass Bonanza Megaways is available at casinos carrying Pragmatic Play’s portfolio, which includes the majority of major licensed operators. A free demo version is typically available at Pragmatic Play-supported casinos before depositing. The game runs on mobile and desktop without any functional difference, the Megaways grid adapts cleanly to portrait mode on phones, and the cascade animations are readable on smaller screens. As with any high-volatility slot, I recommend playing within a session budget you are comfortable losing entirely, and using the minimum bet to extend your playing time when exploring the game for the first time.
