Big Bass Bonanza
1xBet carries Big Bass Bonanza in its casino games lobby — the Pragmatic Play fishing slot that wraps a fairly simple design around a collection mechanic capable of pushing the final result well beyond what the base game suggests on its own. There are no cascading reels or huge grids here — just a fisherman who collects cash values off fish symbols, and a retrigger chain that keeps stacking multipliers higher with each pass. This guide covers the mechanics in full, then adds what most Big Bass Bonanza reviews skip: the actual house edge translated into Rand, and an honest note on which frequency claims about this game can and can’t be trusted.

A note on volatility and frequency claims: independent sources don’t fully agree on how to label this game’s volatility — some describe it as “medium-high,” others as straightforwardly “high,” largely because the base game pays modestly while the bonus round carries most of the value. More importantly, no reliable, independently confirmed figure exists for hit frequency or natural bonus-trigger frequency — numbers circulating online for both vary widely (hit frequency estimates alone range from roughly 13% to over 30%), and several sources quoting very precise figures show other signs of unreliable, generated content. This guide treats those two figures as unconfirmed rather than repeating any single one as fact, and builds the math below entirely from the one number that is consistently and independently corroborated: RTP.

Big Bass Bonanza Interface
Look and Feel
The action takes place underwater, with reels separated by bubble lines and framed by aquatic plant life that keeps the whole scene visually coherent without overcrowding it. The soundtrack mixes natural sounds with a light jazz touch, and the tone shifts to something livelier the moment a win lands or the free spins round triggers, mimicking the feeling of getting a bite on the line.
Symbol Payout Table
The symbols split between standard playing cards and elements tied directly to the fishing theme. The values below are multipliers of the total stake:
| Symbol | 3 symbols | 4 symbols | 5 symbols |
|---|---|---|---|
| A / K / Q / J / 10 | x0.5 | x2.5 | x10 |
| Fish | x1 | x5 | x20 |
| Tackle box / dragonfly | x2 | x10 | x50 |
| Fishing rod | x3 | x15 | x100 |
| Multi-coloured float | x5 (3 symbols) | x20 | x200 |
The float is the highest-paying standard symbol in the game, and the only one that pays out with as few as two appearances (x0.5). The gap between standard playing cards and the theme-specific symbols is fairly wide, which is a common pattern in Pragmatic Play’s design to give visual and financial weight to the game’s own thematic elements.
The Fisherman and Its Role in Free Spins
The fisherman symbol only appears during the free spins round, where it acts as a wild, substituting for any standard symbol to complete combinations. But its real function goes further than that: some fish symbols on screen carry attached cash values — ranging from x2 to x2,000 the stake — and these values don’t pay out automatically just by the fish landing on its own.
Collection mechanic. When a fisherman symbol lands during a free spin that already has fish with attached values on screen, it collects all of those visible values in that particular spin and pays them out as a single win. Two fish worth x5 and x10 with no fisherman present pay nothing at all; with one fisherman, those same two values turn into a win of x15 the stake; with two fishermen landing in the same spin, each one collects the values separately, pushing the total up to x30 the stake.
Triggering and Retriggering the Free Spins
The round activates with 3 fishing boat symbols (scatter) or more landing anywhere on screen during a base game spin:
- 3 scatter symbols → 10 free spins
- 4 scatter symbols → 15 free spins
- 5 scatter symbols → 20 free spins
The retrigger chain. Every time a fisherman symbol lands during the free spins round, it registers on a counter positioned above the grid. Once 4 fisherman symbols accumulate, 10 additional spins are awarded automatically, along with a new multiplier applied to every subsequent fish collection. The first multiplier reaches x2, the second — after the next retrigger — climbs to x3, and the third, the highest available, rises to x10.
This means a single free spins round can turn into a long chain of multiplied rounds if the fisherman keeps appearing regularly, which is exactly why some sessions end up well above the theoretical average — and exactly why an unconfirmed single frequency number for how “often” this happens wouldn’t capture the real shape of the game’s variance anyway.
The Dynamite Feature
In some versions of the game, if a fisherman symbol lands during a free spin with no collectable fish symbols on screen, the Dynamite feature can trigger at random. Once activated, additional fish symbols with random values appear immediately on screen, giving the fisherman something to collect instead of leaving the spin completely empty. This feature isn’t guaranteed to fire on every occasion, and isn’t confirmed to be present in every operator’s version — it works as a random safety net that reduces the odds of a fully wasted collection spin where it’s active.
The Real Math: House Edge and What It Means in Rand
An RTP of 96.71% means the house edge is 3.29% — for every R100 wagered over a large number of spins, the game is designed to return R96.71 and keep R3.29. If your specific operator runs the lower 95.67% or 94.5% configuration instead, the house edge rises to 4.33% or 5.5% respectively — a meaningful difference over a long session, and worth checking in the paytable before playing.
Expected loss per spin scales directly with bet size:
| Bet size | Expected loss per spin (at 96.71% RTP) |
|---|---|
| R2 | R0.07 |
| R10 | R0.33 |
| R50 | R1.65 |
| R200 | R6.58 |
| R4,500 | R148.05 |
Bankroll Planning by Bet Level
| Bet size | Expected cost per 100 spins | Expected cost per 500 spins |
|---|---|---|
| R2 (minimum) | R6.58 | R32.90 |
| R10 | R32.90 | R164.50 |
| R50 | R164.50 | R822.50 |
| R200 | R658.00 | R3,290.00 |
| R4,500 (maximum) | R14,805.00 | R74,025.00 |
Turning this into a practical bankroll. Because the bonus-trigger frequency for this game isn’t reliably confirmed (see the note in the specifications section), the safest approach is to budget conservatively rather than anchor to any single circulating number. Setting aside 3–5x the “expected cost per 500 spins” figure for a chosen stake gives room to absorb a longer-than-average wait for the free spins round without exhausting the bankroll — at R50 a spin, that means treating R822.50 as the theoretical cost of 500 spins but budgeting closer to R2,500–R4,100 before starting, precisely because this game’s real dry-spell length isn’t something that can be stated with confidence from available data.

Bet Limits in South African Rand
Big Bass Bonanza offers a fairly wide betting range that suits different budgets. The minimum bet sits at around R2 per spin, while the maximum can go up to around R4,500 per spin. This broad range makes the game accessible both for lower-risk sessions and for anyone after higher stakes. The exact settings can vary by operator, so it’s worth checking the rules panel inside the game before getting started.
Volatility and What It Means in Practice
Whether labelled “medium-high” or “high” depending on the source, Big Bass Bonanza’s volatility profile means stretches without meaningful wins can run fairly long before a free spins round with stacked multipliers arrives. The game doesn’t aim for constant small payouts — its identity is built around the collection mechanic landing big when the fisherman shows up consistently during a bonus round, with the retrigger chain doing most of the work of separating an average session from an exceptional one, rather than steady, predictable returns from the base game alone.
A Strategic Approach to Playing
The game runs on certified random generation, and there’s no way to control when the fisherman will appear or how many scatter symbols will land. What follows is organisational, grounded in the confirmed math above rather than in unverified frequency claims:
Use the bankroll table’s wider buffer, not the bare expected-cost figure. Since no confirmed number exists for how far apart bonus rounds actually land, budgeting the 3–5x range from the Rand section above is more honest than assuming any specific spin count will reach the feature.
Track the fisherman counter during free spins, not the base game. Reaching 4 fisherman symbols means a retrigger is coming with a new multiplier attached — this is the one countdown in the game that’s fully transparent and worth watching closely, unlike base-game scatter counts, which reset with no bearing on the next spin.
Keep the stake fixed throughout an active free spins round. The stake set at the start of the round is what determines the value of every collection that follows, so keeping it steady avoids any confusion in calculating the expected win.
Treat any online claim of an exact “bonus every X spins” figure with scepticism. As the note above explains, no consistent, independently verified number exists for this game — a specific-sounding figure on a review site is not the same as a confirmed one.
1xBet Bonuses for Big Bass Bonanza Players
1xBet offers a welcome package spread across four deposits for anyone opening a new account. The first deposit adds a 100% match up to R6,000 plus 30 free spins on Reliquary of Ra, the second brings a 50% match up to R7,000 plus 35 free spins on the same title, the third adds a 25% match up to R8,000 plus 40 free spins on Juicy Fruits 27 Ways, and the fourth deposit rounds off the package with another 25% match up to R9,000 plus 45 free spins on Rich of the Mermaid Hold and Spin. This is a general casino welcome package rather than one specific to Big Bass Bonanza — none of the included free spins run on this title. The bonus comes with wagering conditions that need to be completed within a set time window, along with a capped maximum stake while clearing it. It’s worth reviewing the full terms before opting into any offer.
Registration and Getting Started
Registration on 1xBet takes just a few minutes via email, a phone number with an SMS verification code, or direct authorisation through a social media account. Once the account is set up, it’s worth completing identity verification early to avoid any delays when requesting a withdrawal later on.

Big Bass Bonanza Gameplay
Playing Big Bass Bonanza on Mobile
The simple design translates smoothly to smaller screens, with all controls — stake adjustment, autoplay, and the fisherman counter during free spins — clearly visible throughout. The Android app or iOS app can also be installed for quicker access without going through the browser every time, with balance and history syncing automatically across devices.
Big Bass Bonanza Compared to Similar Fishing Slots
Big Bass Bonanza vs newer entries in the series. The Big Bass series has expanded with titles like Big Bass Amazon Xtreme, with a win ceiling of x10,000, and Big Bass Hold & Spinner Megaways, with a maximum of x20,000 and far more ways to win. The original stays the simplest in terms of rules, while later entries add deeper bonus layers and notably higher win ceilings, generally paired with higher volatility than the 96.71%-RTP original.
Big Bass Bonanza vs Book of Ra Classic. Both rely on a single central symbol that drives the bonus round, but the logic is completely different. Book of Ra is built around a symbol that expands to cover a full reel, while Big Bass Bonanza relies on value collection through the fisherman, with multipliers climbing progressively on each retrigger. Anyone who prefers the direct visual expansion mechanic will find Book of Ra the better match; anyone who prefers accumulation with rising multipliers, and the specific bankroll math shown above, will feel more at home with Big Bass Bonanza.
