Introduction
I'm Mia Stone, and Hold & Win boards are my usual territory, not fishing slots. Big Bass Bonanza is outside my usual lane, but it is the one that launched the whole Reel Kingdom fishing franchise. I wanted to know what the original actually does before forming an opinion on everything that came after it. The slot runs on a 5x3 grid with a fishing float as the top paying symbol, an angler in green waterproofs as the Wild, and an animated fishing dock as the backdrop: water movement in the background, a tackle box to the side, the whole dock scene. I put 1,161 spins through the Pragmatic Play demo to find out.
This is a slot where the base game is essentially a waiting room. The mechanics that matter - the Wild collector, the retrigger chain, the multiplier escalation - all live in the Free Spins feature. Understanding that changes how you read the session data.
How Big Bass Bonanza Works
Grid: 5 reels, 3 rows, 10 fixed paylines. All symbols pay left-to-right from the leftmost reel. Only the highest win per line counts; when multiple lines pay simultaneously, wins add together.
Symbol hierarchy at $1.00 total bet:
- Fishing float (top symbol): 5x = 200x bet, 4x = 20x, 3x = 5x, 2x = 0.5x
- Fishing rod: 5x = 100x bet, 4x = 15x, 3x = 3x
- Dragonfly and tackle box (same value): 5x = 50x bet each, 4x = 10x, 3x = 2x
- Bass: 5x = 20x bet, 4x = 5x, 3x = 1x
- Card ranks (A, K, Q, J, 10 - all identical in value): 5x = 10x bet, 4x = 2.5x, 3x = 0.5x
Every fish paying symbol also functions as a Money symbol. Each spin, a random Money value gets assigned to every fish on screen. Possible values: 2x, 5x, 10x, 15x, 20x, 25x, 50x, or 2,000x of total bet. Those values do nothing in the base game. They exist entirely for the Free Spins mechanic.
The Wild is the angler symbol, and the in-game rules tie it to the bonus: it "appears on all reels during FREE SPINS." In the base game the Wild does not appear at all - every substitution and every Money-symbol collection happens inside the Free Spins round. That is the structural point about this slot: the base game has no Wild to lean on.
Scatter appears on all reels. Three or more Scatter symbols trigger Free Spins.
No tumble. No cascades. No expanding wilds in the base game. This is a standard fixed-payline grid. The mechanics that matter are in the bonus round.
Free Spins and the Wild Collector Mechanic
Free Spins is the whole game. The base game pays are modest - 200x on the fishing float five-of-a-kind is the ceiling, and most spins return card-rank combinations well below that. Every meaningful win comes from the bonus round.
Trigger counts:
- 3 Scatter symbols = 10 free spins
- 4 Scatter symbols = 15 free spins
- 5 Scatter symbols = 20 free spins
In Free Spins, every Wild that lands collects all Money symbol values from every fish symbol visible on screen at that moment. Those collected values accumulate across the entire round and pay out at the end.
Retrigger mechanic: every 4th Wild collected triggers another 10 free spins and advances the multiplier.
| Wilds Collected | Trigger | Spins Added | Multiplier on Retriggered Spins |
|---|---|---|---|
| 4 | 1st retrigger | +10 | 2x |
| 8 | 2nd retrigger | +10 | 3x |
| 12 | 3rd retrigger | +10 | 10x |
Three retriggers maximum. The multiplier applies to retriggered spins only, not retroactively. After the 3rd retrigger, no further retriggers are possible. Total free spins at a full chain: 10 (or 15 or 20) + 30 retriggered = up to 50 total.
The 10x multiplier on the final phase is where the headline win potential lives. A 2,000x Money symbol collected by a Wild during the 10x phase produces 20,000x on that single collection in theory. In practice, the global cap cuts in: if the Free Spins round total reaches 2,100x bet, the round ends immediately and remaining spins are forfeited. The 2,100x ceiling is real and will truncate the final phase of a strong run.
There is also a "special reels" mechanic: randomly, when only one Wild is on screen at the end of a free spin, additional fish Money symbols can appear at random positions. The in-game wording: "Randomly, when there is only 1 WILD symbol on the screen, at the end of a free spin, fish MONEY symbols can appear in random positions."
The structure holds up. Four Wilds to each retrigger, multiplier escalating across three retrigger stages - a max chain requires consistent Wild landings, not a single lucky spin. Most Free Spins rounds will resolve without reaching the 3rd retrigger. The ones that do, and that hit strong Money symbol values in the 10x phase, are why this franchise still sells.

Session: 1,161 Spins in the Pragmatic Play Demo
This review runs off a real demo session on Pragmatic Play's direct demo - 1,161 spins at $1.00 a spin, about an hour and a half of play, with the key moments captured on screen.
The game opens straight onto the 5x3 grid at the $1.00 default bet: card ranks (A, K, Q, J, 10) sharing the reels with the tackle-box Money symbols, the angler up top. The bottom control bar carries a "HOLD SPACE FOR TURBO SPIN" prompt for faster play, with standard autoplay otherwise.
The base game is a waiting room, exactly as the math implies - card-rank lines tick over for small amounts while the real money stays locked behind the Free Spins. This session bore that out, and the bonus did trigger: three Scatters dropped a 10-free-spin round, and from there the Wild collector took over.
The best bonus captured here closed at $40.00 on the $1.00 bet - 40x the stake - with mid-round "MEGA WIN" flashes near $38 as Wilds swept the Money values off the fish. The retrigger meter climbed the 2x / 3x / 10x stages as collected Wilds stacked up. That is a modest result for a high-volatility slot - the 2,100x ceiling sits far above it - but it is the headline mechanic working as designed, not a dead run.
Session Stats
Between bonuses the base game does what the paytable says it will: card-rank lines pay 0.5x to 10x and tick over often enough to keep the reels moving, with the fish and the higher-value float and rod symbols scarcer. Nothing in the base game approaches the bonus - the gap between a card-rank line and a $40 Free Spins round is the whole point of a high-volatility build like this.
These figures come from a single demo run and are not predictive. One 1,161-spin session is far too short to say anything about long-run return rates or how often the bonus really lands - it shows the mechanic firing once and paying as designed, nothing more.
RTP and Volatility
RTP at 96.71% is above average for high-volatility titles in this tier - comparable Pragmatic Play entries often sit at 96.21-96.50%. The figure is verbatim from the in-game Game Rules. Individual casino operators may configure a lower RTP on their version. Always check the game's rules at your casino before depositing.
Volatility is labeled High in the in-game rules. The in-game description: "High volatility games pay out less often on average but the chance to hit big wins in a short time span is higher." SlotCatalog rates it Medium-High (4/5) - the in-game label takes priority in my analysis.
Pros and Cons
Pros
- 96.71% RTP confirmed verbatim from in-game screen - above average for high-volatility slots
- Wild collector Free Spins structure is coherent: big wins come from a sustainable mechanism, not a single spike
- $0.10 minimum bet enables extended sessions on a tight bankroll
- 10 fixed paylines across the card ranks give the base game a low-value but steady hit profile by design
Cons
- No Buy Bonus - Free Spins must trigger organically (Bigger Bass Bonanza 2021 added it)
- Free Spins expected roughly once per 200-250 spins: $200-250 in expected spend per trigger at $1.00
- 2,100x hard cap truncates what a max retrigger chain can actually deliver
- No Wild in the base game at all - it is a Free-Spins-only symbol, so the base game leans entirely on the paytable
- No Gamble feature
Big Bass Bonanza vs. the Competition
| Game | Grid | RTP | Max Win | Key Difference |
|---|---|---|---|---|
| Big Bass Bonanza (2020) | 5x3, 10 lines | 96.71% | 2,100x | Original: no Buy Bonus |
| Bigger Bass Bonanza (2021) | 5x4, 12 lines | 96.71% | 4,000x | Upgraded grid + Buy Bonus added |
| Fishin' Frenzy (2014) | 5x3, 10 lines | ~95-96% | ~500x | Mechanical ancestor: no multiplier chain |
| Book of Dead (2016) | 5x3, 10 lines | 96.21% | 5,000x | Expanding symbol vs. cash-collect mechanic |
vs. Bigger Bass Bonanza
The direct successor: 5x4 grid, 12 paylines, max win raised to 4,000x, Buy Bonus added. The core mechanic - Wild collector, retrigger chain, multiplier escalation - is the same structure. The original stays relevant at casinos that stock it without the sequel, and the $0.10 minimum bet is identical across both. If Buy Bonus matters, the 2021 version is the one. If Buy Bonus does not matter and the Wild collector mechanic is the draw, the original does the job.
vs. Fishin' Frenzy
Fishin' Frenzy is the acknowledged mechanical ancestor - a Wild fisherman collecting values during the bonus, predating this game by six years. No multiplier chain, no retrigger escalation. RTP varies by version in the 95-96% range. Think of it as the proof of concept. Big Bass Bonanza is the version with the compounding retrigger bolted on and the volatility cranked up.
vs. Book of Dead
Different theme, similar audience. Both are high-volatility single-feature slots with RTP above 96% and no Buy Bonus in the original version. Book of Dead sits at 96.21% vs 96.71% here. The mechanics differ entirely: Book of Dead uses an expanding chosen symbol during Free Spins, no cash-collect element. Big Bass Bonanza adds a running collection total across the bonus round - a mechanical layer that Book of Dead does not have. That difference splits the audience more cleanly than theme or volatility does.
