Updated: July 2026
The first direct sequel to the original, released in the fall of 2021. The developers didn't try to reinvent the gameplay—they expanded the grid, added a row, and doubled the maximum payout.
The action has been moved from a tranquil lake to a neon-lit harbor in the tropics—in Pragmatic Play’s announcement, the setting was compared to Miami.
Key Features
| Parameter | Meaning |
|---|---|
| Developer | Reel Kingdom |
| Publisher | Pragmatic Play |
| Release Date | September 17, 2021 |
| RTP (basic configuration) | 96,71% |
| Alternatives to the RTP | 95,67% · 94,62% |
| Volatility | 5 out of 5 (high) |
| Reels × Rows | 5 × 4 |
| Lines | 12 fixed |
| Min. rate | 0,12 |
| Max. rate | 240 |

| Purchasing a Bonus | has not been reliably confirmed |
| Mobile version | there is |
There are two things worth noting here.
First, Volatility rose to 5 out of 5 compared to 4 out of 5 on the original. The suspension is stiffer now.
Second, the game Three RTP configurations — 96.71%, 95.67%, and 94.62%. The difference between the upper and lower limits is more than two percentage points, which is significant. The specific version used by a given casino is always specified in the game rules.
What has changed compared to the original?
This is the main question about this type of slot, so I'll address it separately.
The grid is now 5×4 instead of 5×3, and there are 12 lines instead of 10. More paylines mean more cash symbols appear on the screen at the same time, which means a higher potential payout per spin.
The cap has increased to ×4,000 from ×2,100. In its own announcement, Pragmatic Play described this as effectively doubling the maximum multiplier of the original game.
A money-collecting mechanic has been added to the base game. Five matching fish symbols pay out their respective values without triggering free spins. In the original game, the base game is essentially empty in this regard—the cash symbols there simply fill space until the bonus round begins.
The Golden Fish Scatter symbol is worth ×4,000 based on the rate.
The situation has changed From a lake at dawn to a neon-lit harbor at night, lined with palm trees.
How Free Spins Work
The logic is the same as in the entire series.
| Skaters | Free Spins |
|---|---|
| 3 | 10 |
| 4 | 15 |
| 5 | 20 |
During free spins, the Wild Fisherman collects the values of all money symbols visible on the screen. Every 4th fisherman you collect grants +10 free spins and increases the multiplier:
| Retrigger | Multiplier |
|---|---|
| First (4 fishermen) | ×2 |
| Second (8 fishermen) | ×3 |
| Third (12 fishermen) | ×10 |
A maximum of three retriggers. After ×10, the ladder closes—from that point on, you can only increase the total amount, not the multiplier.
It’s actually the fourth row that works in the player’s favor here: there are more coin symbols across the 20 positions than there are across the 15 in the original version, so a single spin by the fisherman during the ×10 phase can yield significantly more.
Symbols
Fisherman — wild and collector. Goldfish — Scatter, value ×4,000. Moneyfish — with the specified rate multipliers. Higher-order symbols — fishing tackle and equipment, junior — Card values from 10 to ace.
Thoughts on the Game
The Bigger Bass Bonanza is the original, taken to its logical next step, without any attempt to invent something new.
The bonus feature in the base game really livens things up: waiting for the bonus no longer feels like a total waste of time. But the 5/5 volatility is still very much present—the dry spells here are longer than in the original, but they’re offset by bigger payouts.
The betting range of 0.12–240 accommodates both conservative play and high stakes. The minimum bet is slightly higher than in the original game (0.12 versus 0.10)—this is due to the twelve paylines instead of ten.
The estimated win frequency of 12,11% (roughly one winning spin out of every eight) is cited in only one source, so it should be treated with caution. Pragmatic Play does not officially publish this data.
Pros and Cons
| ✅ Pros | ❌ Cons |
|---|---|
| Ceiling ×4,000 — twice as high as the original | Volatility 5/5, tight spread |
| Collecting money symbols works in both the base game and the bonus game | Three RTP configurations; the bottom one is 94,62% |
| The 5×4 grid features more money symbols | The mechanics are essentially the same as in the original |
| RTP 96,71% in the top assembly | The purchase of the bonus has not been confirmed |
| Vibrant neon decor | The game is already falling short compared to later titles in the series |
What to compare it to

- Bass Boss - Bass Boss From Red Tiger — the collector collects data by rows and also operates in the base
- Blast the Bass - Crank up the bass from Belatra to RTP, 96,72%, and a much more generous bonus

Frequently Asked Questions
How does the Bigger Bass Bonanza differ from the Big Bass Bonanza?
Four main differences: a 5×4 grid instead of 5×3 (12 paylines vs. 10), a maximum win of ×4,000 instead of ×2,100, the coin symbol collection feature works in the base game as well, and volatility has been increased from 4/5 to 5/5.
What is the RTP in the Bigger Bass Bonanza?
96,71% in the base configuration. There are also versions with 95,67% and 94,62%—check the game rules to see which one the casino uses.
What is the maximum payout?
×4,000 the bet. This figure has been confirmed by an official announcement from Pragmatic Play.
Is there a bonus purchase?
We were unable to confirm this with certainty: the developer’s official website does not list this setting, and data from various platforms is contradictory. The availability of the “Buy” button also depends on the jurisdiction—in some countries, this feature is prohibited.
What is the maximum number of free spins you can get?
20 starting spins for five scatters, plus up to three retriggers of 10 spins each—that is, up to 50 free spins per round.
Final Grade
8 / 10
A solid sequel: the developers have genuinely improved upon what players were asking for. The fourth row and the collection feature in the base game address the main complaint about the original. The downside is that, mechanically, it’s still the same slot game, and compared to the version released in 2025, the ×4,000 cap is no longer impressive.
Gamble responsibly. Gambling is a form of entertainment, not a way to make money. The outcome of each spin is determined by a random number generator. Only gamble with money you can afford to lose.
If the game is no longer fun, seek help. International services: BeGambleAware.org - Link, GamCare - Link, Anonymous Players (Russian) - . Most casinos offer self-limitation and self-exclusion tools—make use of them.
