How Big Bass Bonanza Megaways's special symbols work

fish
The fish paying symbols are also MONEY symbols. At every spin, the fish take a random money value which can be won during the FREE SPINS feature. Possible values are 2x, 5x, 10x, 15x, 20x, 25x, 50x or 4000x total bet. In the base game, the fish symbols explode and tumble normally. In the free spins, they do not explode and just fall to the bottom of the screen as tumbles happen.
WILD (fishing net)
This symbol is WILD and substitutes for all symbols except for SCATTER and FISHERMAN symbol. WILD symbol appears only on reels 2, 3, 4 and 5 on the top row.
SCATTER
This is the SCATTER symbol. It appears on all reels. Hit 3 or more SCATTER symbols anywhere on the reels to trigger the FREE SPINS ROUND.
FISHERMAN
This is the FISHERMAN symbol. It appears on all reels only during the free spins round.

Big Bass Bonanza Megaways features

Tumble Feature
The TUMBLE FEATURE means that after every spin, winning combinations are paid and all winning symbols disappear. The remaining symbols fall to the bottom of the screen and the empty positions are replaced with new symbols coming from above. New symbols are of the same size as the inital spin result, before tumbles. Tumbling will continue until no more winning combinations appear as a result of a tumble. All wins are added to the player's balance after all the tumbles resulted from a base spin have been played.
Free Spins
Hit 3 or more SCATTER symbols to trigger the FREE SPINS feature. 6x SCATTER awards 25 free spins 5x SCATTER awards 20 free spins 4x SCATTER awards 15 free spins 3x SCATTER awards 10 free spins During the FREE SPINS feature each FISHERMAN symbol collects all the values from MONEY symbols on the screen. All the FISHERMAN symbols that hit during the feature are collected until the end of the round. Every 4th FISHERMAN symbol collected will retrigger the feature, award 10 more free spins and a multiplier for MONEY symbol collection and all wins is increased to 2x for the first retrigger, 3x for the second retrigger and 10x for the third retrigger. The retriggered spins are played after the previous batch of free spins ends. The multiplier applies to the retriggered spins. After the third retrigger, the feature cannot be retriggered anymore. Randomly, when there are only 1 or 2 FISHERMAN symbols on the screen with no fish, at the end of a free spin, a dynamite animation can make fish MONEY symbols appear in random positions. Also randomly, when there are only 1 or 2 FISHERMAN symbols on the screen with no fish, at the end of a free spin, a bazooka animation can appear and change all the symbols from the screen except for FISHERMAN. Special reels are in play during the feature.

Big Bass Bonanza Megaways Overview

Big Bass Bonanza Megaways is a medium volatility slot by Pragmatic Play with an RTP of 96.71%. This game plays across 6 reels. Play Big Bass Bonanza Megaways for free on Slottomat, compare the core stats quickly, and browse trusted slot offers available in your market.

Reeling In 46,656 Ways: How the Grid Works

Each of the six reels shows a variable number of symbols per spin, and the number of active ways shifts with it, up to the 46,656 maximum. Wins pay left to right across adjacent reels, starting from the leftmost. A tumble feature removes winning symbols and drops new ones into the gaps, so a single spin can chain several consecutive wins. Bets run from 0.20 per spin. The setting is a lake at dawn — blue water, green reeds and a country soundtrack — and the visuals stay sharp on both mobile and desktop.

Fisherman, Fish and the Rest of the Catch

Low-pay symbols are the card ranks 10 through Ace; the high-pay icons are fishing gear such as rods, tackle boxes, boots and hats. A wild substitutes for the regular paying symbols, though not for the fish or fisherman symbols. The fisherman is the special Collect symbol used in the free spins, and the leaping bass is the scatter that triggers the bonus. Fish cash symbols also drop in the base game with instant values attached — usually small hits, but they keep sessions active and preview the collect mechanic that drives the bonus.

Money Collect Free Spins

Landing 3, 4, 5 or 6 scatters awards 10, 15, 20 or 25 free spins. During the bonus, fish symbols land carrying set cash values, and each fisherman that appears collects every value showing on screen at that moment. Every fourth fisherman collected retriggers 10 extra free spins and steps the collect multiplier up — to 2x, then 3x, and finally 10x. Chaining collects while a multiplier is active is the route to the biggest payouts in this mode, including the 4,000x ceiling.

RTP 96.70%, High Volatility and the 4,000x Cap

The default RTP is 96.70%, slightly above the common 96% baseline; operators can run lower configurations, so check the in-game information panel. Volatility is high — expect dry spells between wins, with the payouts that do land tending to be larger. The maximum win of 4,000x your stake comes from a strong free spins run with retriggers and stacked multiplier upgrades. It is possible but rare, so set a session balance before you play.

Testing the Demo Before You Cast

High-volatility games reward patience. Give yourself at least 50 to 100 spins in demo mode before forming a view, and start small to feel how the Megaways grid shifts. Watch how the fish cash symbols behave in the base game, since they preview how the Money Collect rounds play out. If you enjoy this style, the original Big Bass Bonanza covers the core series formula, while The Dog House Megaways and Great Rhino Megaways offer more of the studio's Megaways action.
