Bigger Bass Bonanza
Bigger Bass Bonanza is Pragmatic Play's follow-up to the original Big Bass Bonanza, expanding the grid to 5x4 and keeping the fishing theme that made the series one of the studio's most recognisable franchises. The default RTP is 96.71%, the highest default figure among the six Pragmatic titles reviewed here, and the game runs high volatility on just 12 paylines. The free-spins mechanic centres on a fisherman wild who collects fish symbols worth escalating values, with the largest fish paying up to 4,000x the stake.
Key takeaways
- RTP: 96.71% default, the highest of the series. Pragmatic ships lower builds; check the info panel before you play.
- Volatility: high. Only 12 paylines on a 5x4 grid means base-game wins are less frequent; the collector mechanic in free spins drives the large results.
- Max win: 4,000x your stake, reached when the highest-value fish symbols are collected repeatedly by the fisherman wild during free spins.
- Collector mechanic: the fisherman wild collects any fish symbol it lands on during free spins and pays their value; more fisherman wilds in the round accelerates collection.
- Layout: 5x4, 12 paylines; the wide grid and low payline count makes the fisherman wild the dominant source of value.

A wider grid, the same fishing formula
Bigger Bass Bonanza keeps everything that made the original series successful and scales it up. The grid moves from 5x3 to 5x4, adding a full extra row of symbol positions across all five reels. The payline count stays at 12, which means the added row doesn’t multiply winning combinations mechanically, but it does add more positions for fish symbols and fisherman wilds to land, increasing the frequency with which they occupy the same columns.
The theme is fishing: the fisherman is the wild, various fish fill the reels as both paying symbols and the collector targets, and the rod and tackle serve as scatters. The visual language is clear enough that the mechanic reads without instruction: if the fisherman and a fish share a column, the fisherman collects.
RTP at 96.71% and what it means in practice
Among the six Pragmatic Play slots covered in this series of reviews, Bigger Bass Bonanza carries the highest default RTP at 96.71%. That figure means the game’s long-run return to players is about 0.7% better per bet than a 96.01% title like Wolf Gold. On a high-volatility game the difference is only visible across a large number of spins, but it is real and it compounds. Pragmatic’s lower-RTP configurations still apply, so the info panel check before playing is as relevant here as on any other title.
High volatility with 12 paylines means the base game is not the entertainment. Payline wins land, but with only 12 combinations active on a 5x4 grid the between-bonus portions of a session are quiet by design. The game’s weight is in the free-spins collector rounds.
The fisherman wild and fish collection
The collector mechanic is the reason Bigger Bass Bonanza works. In the base game, the fisherman wild substitutes for all paying symbols on the 12 paylines as a standard wild. In free spins, that role extends: each fisherman wild landing on a reel scans its column for fish symbols and collects them, paying their face values immediately as a separate win on top of any payline combination.
Fish symbols carry printed coin values ranging from small amounts up to 4,000x the stake for the rarest large fish. A single fisherman wild landing in the same column as a 4,000x fish pays that amount regardless of the payline result. Two fisherman wilds in the same free spin collect from two columns simultaneously, and if both columns contain high-value fish, the total from collection alone can define the session result.
Free spins and the collection window
Three or more scatter symbols start the free-spins round, with more scatters granting more spins. The value of each free-spins session depends on how many fisherman wilds land, how many fish symbols are present in their columns, and the face values printed on those fish. A round with several fisherman wilds and multiple large fish landing in their columns is the high-end outcome; a round where wilds and fish avoid each other’s columns produces the low end.
Retriggering free spins by landing more scatters during the round extends the collection window, keeping the same reel structure with its mix of fish values available for more collection opportunities.
Bankroll position and where to play
Twelve paylines on a high-volatility game means the base game between bonus triggers runs quietly and the stakes-per-spin attrition is real. A bankroll sized to absorb an extended trigger wait is the practical requirement. No feature in the game changes the house edge, and the collector mechanic is straightforward to understand but not to control.

Frequently asked questions
What is the RTP of Bigger Bass Bonanza?
Bigger Bass Bonanza has a default RTP of 96.71%, above the typical slot average and the highest default figure in the main Big Bass series. Pragmatic Play supplies lower-RTP builds to operators, and the version at your casino is the one that applies to your real-money play. The game's info panel shows the active figure. On a high-volatility game with only 12 paylines, a lower-RTP build makes a tangible difference over any meaningful number of spins.
How does Bigger Bass Bonanza compare to the original Big Bass Bonanza?
Bigger Bass Bonanza expands the grid from 5x3 to 5x4 and raises the max win from 2,100x to 4,000x. The wider grid adds more positions for both fish symbols and fisherman wilds, making it slightly more likely they share a column on any given spin. The core mechanic is identical: the fisherman collects fish values during free spins, and the collected total drives the result. The original's 10x multiplier ladder is absent here; collection value alone determines the payout.
What is the maximum win on Bigger Bass Bonanza?
The maximum win is 4,000x your stake, reached when multiple fisherman wilds collect the highest-value fish symbols during free spins. It is lower than some Pragmatic high-volatility titles, but the 96.71% default RTP compensates with a better long-run return across base-game and average bonus sessions. It is a mathematical ceiling, not a realistic session target.
How do you trigger free spins in Bigger Bass Bonanza?
Landing three, four, or five scatter symbols anywhere on the 5x4 grid triggers free spins. Three scatters award 10 spins; four award 15; five award 20. During the round the fisherman wild's collector function activates: any fisherman wild landing on a reel scans its column for fish symbols and pays their face values as a separate win. Landing more scatters during the round retriggers additional spins.
Is there a strategy for Bigger Bass Bonanza?
No strategy changes the house edge. The default RTP is 96.71% on every spin, regardless of bet size or timing. The practical approach is to keep stakes proportional to your session budget so you can reach the free-spins round multiple times, since the collector mechanic is where the game's value concentrates. Adjusting stakes mid-session to recover losses shortens the session without improving your odds.
Can you buy the bonus in Bigger Bass Bonanza?
Yes, where the casino and local regulation permit it. The bonus buy enters the free-spins collector round directly at a fixed multiple of your stake. It does not change the expected return of the feature itself; it bypasses the base-game scatter route. Confirm availability in the game interface before committing, as jurisdiction rules vary.
