Background: Reel Kingdom and the Big Bass Franchise
Behind the success of Big Bass Bonanza stands a unique production duo. The game was designed by Reel Kingdom studio, which is responsible for the mechanics, mathematics, and the distinctive fishing theme. The official publisher and distributor is Pragmatic Play — it is thanks to their technology platform that the game runs smoothly on every device and is available at online casinos worldwide, often serving as a flagship title in the Pragmatic Play portfolio.
Released on 3 December 2020, Big Bass Bonanza drew clear comparisons to Fishin' Frenzy from Reel Time Gaming, borrowing the core concept of a fisherman collecting cash fish during free spins, but adding a progressive multiplier system that gave the format a meaningful upgrade.
The game caught on fast. Within a few years it had spawned one of the most prolific slot franchises in the industry: Bigger Bass Bonanza, Big Bass Splash, Big Bass Bonanza Megaways, Keeping It Reel, Big Bass Amazon Xtreme, Big Bass Day at the Races, Big Bass Hold & Spinner Megaways, Big Bass Bonanza 1000, and seasonal Halloween and Christmas variants. The original 5×3 title still ranks among the most-played slots globally and is the entry point most players start with before exploring the rest of the series.
How Does Big Bass Bonanza Work?
The grid is 5 reels, 3 rows, with 10 fixed paylines. All paylines are always active. Wins pay left to right on adjacent reels from reel 1. Only the highest win is paid per line; wins on multiple paylines are added to the total.
The base game is deliberately simple — no Wild symbol, no cascades, no bonus meter. You spin, match symbols on paylines, and aim to hit three or more Scatter symbols to trigger Free Spins. The base game is a grind by design; the real action is in the bonus round.
Symbol hierarchy (low to high): card royals (10, J, Q, K, A) → Fish (Money Symbols, also pay on paylines) → Dragonfly → Tackle Box → Fishing Reel → Fishing Float (top symbol). The Scatter (green fish with "SCATTER" label) appears on all reels and pays anywhere.
Key Features and Bonuses
Scatter Symbol (green fish): appears on all reels. Landing 3, 4, or 5 Scatters anywhere triggers Free Spins:
- 3 Scatters → 10 Free Spins
- 4 Scatters → 15 Free Spins
- 5 Scatters → 20 Free Spins
Money Symbols: the fish paying symbols are also Money Symbols. Every spin, each Money Symbol on the reels takes a random value. Possible values: 2x, 5x, 10x, 15x, 20x, 25x, 50x, or 2,000x total bet. These values are what the Fisherman Wild collects during Free Spins.
Fisherman Wild: appears on all reels, but only during Free Spins — not in the base game. Substitutes for all symbols except the Scatter. When a Fisherman Wild lands, it collects the values from all Money Symbols visible on the reels at that moment. All collected Wilds accumulate until the end of the round.
Retrigger and Progressive Multiplier: every 4th Fisherman Wild collected retriggers the feature:
- +10 Free Spins added
- Multiplier for Money Symbol collection increases: 2x (1st retrigger) → 3x (2nd) → 10x (3rd)
- After the 3rd retrigger, no further retriggers are possible
- The multiplier applies to all retriggered spins going forward
Dynamite Feature: activates randomly when exactly 1 Fisherman Wild lands with no Money Symbols visible on the reels. Dynamite explodes in random positions, adding fish Money Symbols to the screen so the Wild always has something to collect.
Max Win: 2,100x your bet. If the total win of a Free Spins round reaches 2,100x, the round ends immediately — remaining spins are forfeited and the cap is awarded.
Paytable
All symbols pay left to right on selected paylines. All wins multiplied by bet per line. Only the highest win is paid per line.
Paytable values shown at $2.00 total bet (base stake in game rules). Amounts scale with your chosen bet. Money Symbol values (2x–2,000x total bet) are separate from payline payouts and are only collected by the Fisherman Wild during Free Spins.
RTP, Volatility, and Bet Range
High volatility means the base game produces long stretches without significant wins. The design is intentional — the base game is a grind; Free Spins is where the math is concentrated. Budget for 100+ spins per session before expecting a bonus trigger.
Big Bass Bonanza vs the Series
If you enjoy this game, the Big Bass franchise has expanded significantly. Key differences from the original:
- Bigger Bass Bonanza — 5×4 grid, 12 paylines, max win 4,000x; same core mechanic with more room
- Big Bass Splash — lake setting, Golden Wilds with level-up multipliers, up to 20 free spins
- Big Bass Bonanza Megaways — dynamic grid up to 46,656 ways, tumbling reels, bazooka modifier
- Big Bass Amazon Xtreme — improved bonus features, max win 10,000x
- Big Bass Hold & Spinner Megaways — up to 147,456 ways, max win 20,000x, RTP 96.7%
- Big Bass Bonanza 1000 — Money Symbols up to 1,000x value, max win 25,000x
Bankroll and Strategy Notes
Big Bass Bonanza is high volatility with no base game Wild and no Bonus Buy at Wolfbet. Everything depends on hitting Free Spins organically.
- Budget minimum 100× your bet per session — the bonus can take a long time to trigger; dry spells of 200+ spins are normal
- Bet sizing is your only lever at Wolfbet — since Buy Feature is not available here, smaller bets = more spins = more chances to hit 3+ Scatters
- During Free Spins: patience with the retrigger pays off — each 4th Wild collected pushes the multiplier to 2x, 3x, then 10x; the 10x multiplier on a 2,000x Money Symbol collect alone approaches the 2,100x cap
- The 2,100x cap ends the round immediately — if you hit a big multiplier early and a 2,000x Money Symbol lands, the round may end before all spins are used
- Dynamite Feature is a safety net — it only fires when a Wild lands with nothing to collect, ensuring the Wild always produces a return

Who developed Big Bass Bonanza?
Behind the success of Big Bass Bonanza stands a unique production duo. The game was designed by Reel Kingdom studio, which is responsible for the mechanics, mathematics, and the distinctive fishing theme. The official publisher and distributor is Pragmatic Play — it is thanks to their technology platform that the game runs smoothly on every device and is available at online casinos worldwide, often serving as a flagship title in the Pragmatic Play portfolio. Big Bass Bonanza was released on 3 December 2020 and became Reel Kingdom's breakthrough title, spawning one of the most successful slot franchises of the last five years.
What is the maximum win in Big Bass Bonanza?
The maximum win is 2,100x your bet. If the Free Spins round total reaches this cap, the round ends immediately and the maximum is awarded. The cap is most commonly approached through a combination of high Money Symbol values (up to 2,000x total bet each) collected by the Fisherman Wild with an active multiplier.
How do Free Spins work in Big Bass Bonanza?
Landing 3, 4, or 5 Scatter symbols anywhere triggers 10, 15, or 20 Free Spins. During the round, Fisherman Wilds appear on all reels and collect the values of any Money Symbols visible when they land. Every 4th Wild collected retriggers the feature (+10 spins) and raises the collection multiplier: 2x after the 1st retrigger, 3x after the 2nd, 10x after the 3rd. No further retriggers after the 3rd.
What are Money Symbol values in Big Bass Bonanza?
Money Symbols (fish) take a random value each spin: 2x, 5x, 10x, 15x, 20x, 25x, 50x, or 2,000x total bet. These values are collected by the Fisherman Wild during Free Spins — the higher the value and the higher the active multiplier, the bigger the payout.
What is the Dynamite Feature?
If a single Fisherman Wild lands during Free Spins with no Money Symbols visible on the reels, the Dynamite feature can randomly activate. It explodes in random positions, adding fish Money Symbols to the screen so the Wild always has something to collect.
Does Big Bass Bonanza have a Bonus Buy feature?
The Bonus Buy feature (100× bet, available at many other casinos) is not available at Wolfbet as an operator restriction. Free Spins must be triggered organically by landing 3+ Scatters.
