The original slot pays on 10 fixed paylines, while Megaways uses up to 46,656 ways with tumbles. The original slot has 5 reels and 3 rows, while Megaways has 6 reels. A round in the Big Bass Bonanza Megaways bonus ends at once when its total reaches the max win, and unused spins are forfeited.
Big Bass Bonanza Free Spins Bonus
In the base game, the Big Bass Bonanza free spins bonus triggers when scatter symbols land on the reels. During this feature, the fisherman wild appears to collect cash values from money symbols, with potential retriggers extending the round.
Each retrigger raises the multiplier up to a maximum of 10x for bigger wins. Since every Big Bass Bonanza bonus round is completely random, results can vary from a single set of spins to fully maxed-out retriggers.
Scatters and Spins Awarded
Three or more scatters in any position trigger the Big Bass Bonanza bonus, and their number sets the spin count: 3 scatters award 10 free spins, 4 scatters award 15 free spins and 5 scatters award 20 free spins. The scatter can land on any reel of the grid. Only the spin that brings the scatters starts the round.
The scatter symbol appears on all reels. The first batch of spins is set at the trigger, and extra spins come only from retriggers by the fisherman wild.
Fisherman Wild Collects Cash
The fisherman wild appears on every reel only during free spins, and in the Big Bass Bonanza bonus it substitutes for all symbols except the scatter. The fish act as money symbols, and each one carries a random cash value shown beneath it. When a fisherman lands, it collects the values of all fish on the screen and adds them to the win.
The cash is paid when a fisherman lands in the same spin as the fish. Several fishermen in one spin can lead to larger payouts, since each of them collects the fish values on the screen.
Retriggers and Multipliers
Every fourth fisherman retriggers the round and adds 10 extra spins. In the Big Bass Bonanza bonus, each retrigger also raises the multiplier applied to wins: 2x on the 1st retrigger, 3x on the 2nd and 10x on the 3rd.
The 10x multiplier is the highest value of the round. Each fisherman still collects the money symbols on the screen at the moment it lands, so the multiplier works on top of the cash values already in play.
Big Bass Bonanza Bonus Frequency
In the original slot, the Big Bass Bonanza bonus triggers about once per 113 spins on average, according to the official Game Rules of the slot. This long-run average says nothing about a single session, which can pass without free spins or bring two rounds close together. Treat the Big Bass Bonanza bonus frequency as an expectation, not a schedule.
The base game has a 13% hit frequency, which is one winning spin per 7.69 spins on average. The figure is stated for the 96.71% RTP version, while 95.67% and 94.6% versions also exist and the casino picks which one runs. The rules inside the slot show which version you play, so check the RTP in the paytable before you rely on the Big Bass Bonanza bonus frequency and the hit frequency.
Big Bass Bonanza Megaways Bonus
During regular spins, the Big Bass Bonanza Megaways bonus brings the classic fisherman free spins round onto an expanded Megaways grid featuring tumbles. After each win, winning symbols disappear and new ones drop in from above until no winning combinations remain.
In free spins, money symbols do not explode and simply fall to the bottom of the reels, unlike in the base game where they tumble. This dynamic tumbling action makes every Big Bass Bonanza Megaways bonus spin potentially more rewarding before the total win is credited.
Free Spins on Megaways
Three or more scatters anywhere on the reels trigger the Big Bass Bonanza Megaways bonus, and 3, 4, 5 or 6 scatters award 10, 15, 20 or 25 free spins. The fisherman appears on all reels only during the round and collects the values of every money symbol on the screen. Collected fishermen are counted until the round ends, and each fish takes a random value of 2x, 5x, 10x, 15x, 20x, 25x, 50x or 4,000x of the total bet.
When only 1 or 2 fishermen are on the screen with no fish at the end of a free spin, a random animation can follow. A dynamite animation makes fish money symbols appear in random positions, and a bazooka animation changes all symbols on the screen except the fisherman. Special reels are in play during the feature.
Megaways Retriggers and Multipliers
Every 4th fisherman collected during the round retriggers the feature and awards 10 more free spins. The multiplier for money symbol collection and for all wins rises to 2x on the first retrigger, 3x on the second and 10x on the third.
Retriggered spins are played only after the previous batch of free spins ends, and the current multiplier applies to them. Once the third retrigger is reached, the feature cannot be retriggered again.
Big Bass Bonanza Bonus Buy
The original slot has no Big Bass Bonanza bonus buy, so the free spins round starts only from 3 to 5 scatters in the base game. There is no button that skips the base game, and every bonus has to be triggered by the reels. The Big Bass Bonanza Megaways bonus buy belongs to the Megaways game only, and it is not part of the original slot.
In versions of Megaways outside the UK, the Big Bass Bonanza Megaways bonus buy button takes you straight to the free spins round. UK versions have no buy button, so a Big Bass Bonanza bonus buy cannot be used there, and the round starts only from 3 to 6 scatters. The Game Rules inside the game show whether your version includes the feature, so check them before you look for the button.
Big Bass Bonanza No Deposit Bonus
Casinos rarely give free spins on this slot without a deposit, so a Big Bass Bonanza no deposit bonus exists only when a casino runs one. The number of spins and the value of each spin depend on the casino, and the terms of a Big Bass Bonanza slot UK no deposit bonus show both
Check the casino’s promotion page to see whether the offer needs a Big Bass Bonanza promo code, and read the wagering rules and the time you have to use the spins. The demo is free to play, but the Big Bass Bonanza Megaways demo bonus buy button appears only in versions with the feature.
Big Bass Bonanza Sign Up Bonus
Welcome free spins on this slot make up the Big Bass Bonanza sign up bonus, and the casino credits them after your first deposit. The number of spins and the value of each spin depend on the casino you register with.
The casino also sets the minimum deposit, the wagering rules and the time you have to use the spins. Whether you need a Big Bass Bonanza promo code to claim the spins depends on the casino. Read the terms of the Big Bass Bonanza sign up bonus in the casino’s promotion rules before you claim it, since they differ from one casino to another.
Bonus Symbols and Payouts
Three special symbols drive the Big Bass Bonanza bonus: the scatter, the fisherman and the fish money symbol, plus a separate wild in Megaways. In the original slot, 3, 4 or 5 fish also pay 1x, 5x or 20x the bet as regular symbols in the base game. In free spins, a random dynamite feature turns random symbols into fish when 1 fisherman lands with no fish on the screen.
| Symbol | Role in the bonus |
| Scatter | Appears on all reels. Landing 3 or more anywhere triggers free spins. |
| Fisherman | Appears on all reels only during free spins. Collects the values of all money symbols on the screen, and every 4th one collected retriggers the round. |
| Fish (money symbol) | Takes a random cash value on every spin, ranging from 2x up to 2,000x total bet. The fisherman collects these values during free spins. |
| Wild (Megaways) | Substitutes for all symbols except the scatter and the fisherman. Appears only on reels 2 to 5, in the top row. |
In Megaways, symbols pay from left to right on adjacent reels, starting from the leftmost reel. We multiply all wins by the base bet, and only the highest win is paid per winning combination on the same way. The free spins win is credited to your balance after the round completes.
Play the Bonus Round in Demo Mode
The demo lets you watch the Big Bass Bonanza bonus from the first trigger to the last retrigger without staking real money. It runs on virtual credits and needs no registration, so you can see how scatters, fishermen and multipliers behave before you look for a Big Bass Bonanza slot UK no deposit bonus or play with a balance.
Demo results do not predict real money results, since every spin is random. The Big Bass Bonanza Megaways demo bonus buy button appears only in versions with the feature, and UK demos show none, so a round there starts from scatters alone. Use the demo to see how long the base game runs between bonus rounds before you claim a Big Bass Bonanza sign up bonus at a casino.
