BigBassBonanza launched in December 2020. Reel Kingdom’s fishing-themed slot quickly became one of Pragmatic Play’s most-played games. It pairs a 5x3 grid and ten fixed lines with free spins in which a wild fisherman collects money fish.

Big Bass Bonanza at a glance: where the fishing series began

The franchise began with Big Bass Bonanza, introducing the lakeside collection mechanic that later became a defining feature of Reel Kingdom’s series. By 2025, the franchise had expanded to more than a dozen titles. The original game already featured its signature trio: the fisherman wild, float scatter and money fish, all of which remained central to later entries in the series.

The series later expanded beyond the original with several variations built around the same fishing theme. Some releases introduced different bonus structures or higher win potential, while seasonal editions changed the presentation rather than the core concept. Christmas Big Bass Bonanza is one example, adding a festive setting to the familiar format, alongside other spin-offs that developed the series in different directions.

Who built it and when it arrived

Reel Kingdom created the game. Pragmatic Play distributes it through partner platforms. Its wide release followed on 14 December 2020, and the core rules remain unchanged.

A 5x3 grid with ten lines that never switch off

The layout has five reels, each three rows high. All ten fixed paylines pay from left to right. A spin can cost anywhere from $0.10 to $250. Ten lines at $0.01 each make the minimum stake $0.10. Coverage cannot be reduced.

Wins run left to right. Card or themed symbols must land on active lines; cards from 10 through Ace pay up to 10x for five matches. Five fishing rods award 100x, the regular paytable’s top prize.

Big Bass Bonanza demo: free spins of the reels before any stake

A Big Bass Bonanza demo runs in a browser at partner sites, with no account required. The paid game shares its maths engine.

For a more useful practice session, work through these steps:

  1. Set the stake to the amount you would use in real-money play. That makes dry spells easier to judge against your intended budget.
  2. Trigger the bonus round at least three times and observe how often dynamite fires.
  3. Count the fishermen in each round and note whether four arrive to retrigger.
  4. Record the coin values displayed when the round finishes.
  5. Test the minimum and maximum stakes once each to compare the controls.

Based on our experience, the demo shares the paid version’s paytable, its 10 / 15 / 20 free-spin awards, and the 2x, 3x and 10x multiplier steps. Those mechanics carry over.

Limits of practice credit

Practice is not paid play. The demo reproduces the maths engine faithfully, but free credit carries no financial consequence, so long dry spells can feel shorter than they do with real money. It also hides site RTP settings.

Big Bass Bonanza Splash against the original

Released in June 2022, Big Bass Bonanza Splash exceeds the original on every mechanical measure. Our analysis showed that Splash’s broader modifier set – three random in-spin features instead of the original’s single dynamite – creates more session-to-session variance and a higher ceiling for individual outcomes. The principal differences are:

Splash also added two scatter-assist features. Nudging and hook activate when exactly two scatter symbols land and give near-misses another chance. The original offers no equivalent feature.

Paytable of the Big Bass Bonanza slot

Wins use total stake. The Big Bass Bonanza slot pays left to right on ten fixed lines; the table gives total-stake multiples for three to five matches, while the float pays anywhere on the reels.

Symbol 3 on a line 4 on a line 5 on a line
🃏 10, J, Q, K, A 0.5x 2.5x 10x
🐟 Fish 1x 5x 20x
📦 Tackle box 2x 10x 50x
🌿 Dragonfly 2x 10x 50x
🎣 Fishing rod 3x 15x 100x
🪝 Float (scatter) 5x 20x 200x

Scatter awards follow a separate rule. Two floats return 0.5x the total bet, while three, four and five return 5x, 20x and 200x. Scatter payments are added to any line wins on the same spin.

How the angler wild and the float behave

The angler wild, also called the fisherman wild, can replace any regular symbol. The collection feature starts when money fish appear on the same spin. The wild collects the coin value shown on every fish visible on the reels at that moment.

How the angler wild and the float behave in Big Bass Bonanza

If several fishermen land together, each one collects the value of every visible fish independently. With two wilds and four money fish on the reels, both wilds collect all four values. That doubles the collection versus a single wild. At the maximum $250 stake, a single top-value fish is worth $500,000; fish values run from 2x to 2,000x the total stake.

Inside the bonus: spins, fish and collections

Three or more float scatters anywhere on the reels award free spins, the feature that holds most of the game’s potential. Base-game wins are rare.

Triggering the round

Three floats award 10 spins and 5x the total stake; four award 15 spins and 20x, while five award 20 spins and 200x. Fish collection is reserved for the bonus round.

Money fish values and the dynamite

The bonus features eight possible coin values: 2x, 5x, 10x, 15x, 20x, 25x, 50x or 2,000x the total stake. Dynamite is the original’s only random modifier. Activation occurs only when the fisherman appears without any money fish alongside him. The feature places fish at random positions so the fisherman has something to collect instead of an empty wild.

Retriggers and multiplier steps

Our tests showed that every four collected fishermen trigger a retrigger. It adds ten spins and moves the multiplier through 2x first, 3x second and 10x third. No fourth retrigger follows.

Retriggers and multiplier steps in Big Bass Bonanza

Once the round reaches 10x, every fish value is multiplied by ten. A 50x fish then pays 500x the stake. A 2,000x fish reaches 20,000x, but the round ends once it hits the 2,100x cap.

Big Bass Bonanza RTP, volatility and the 2,100x cap

The published Big Bass Bonanza RTP stands at 96.71%. Reel Kingdom gives volatility a 4-out-of-5 rating, classed as medium-high. That profile brings sparse base-game returns and potentially lengthy dry spells. Most of the theoretical return comes through free spins.

Which RTP version a site runs

Some licensed sites use a reduced 95.67% configuration. This figure appears on many aggregator pages and adds roughly one percentage point to the house edge; across 1,000 spins at $1, that difference represents approximately $10.40 in additional expected loss. The operator chooses the configuration and players cannot switch it, so the game’s information screen is the place to check before staking.

The original Big Bass Bonanza tops out at 2,100x. That is the series’ lowest maximum win; Bigger Bass Bonanza reached 4,000x in 2021, while Big Bass Splash 1000, released in 2025, reaches 25,000x. Later titles raise the ceiling.

What medium-high volatility means in practice

Base-game wins arrive less often. Medium-high volatility can leave longer gaps between scatters. Individual payouts may be larger, so budget for many empty spins at your chosen stake. Retriggers can change outcomes. A 10x round may return several times the session stake. Without a retrigger, though, the round usually ends modestly.

Stakes and controls when you play Big Bass Bonanza

The game covers a wide stake range. Before you play Big Bass Bonanza, decide how much you are prepared to spend within the $0.10–$250 stake range. Players use all ten fixed lines whenever the reels are spun.

Big Bass Bonanza Pragmatic Play brings together the game developer and its distributor. Reel Kingdom makes the games. Pragmatic Play places them in partner casinos as part of its catalogue, and the arrangement has continued beyond the original five-reel format. The series keeps growing.

She pointed to the classic fisherman mechanic, 1,000x money symbols and wins up to 20,000x.

Big Bass Bonanza review verdict

A fair Big Bass Bonanza review centres on a focused game. Its bonus turns on a single collection mechanic. One wild, one collection mechanic, one random modifier and one retrigger path define a focused bonus for players who prefer less layered randomness than later entries offer.

Points in its favour

The original game stands out for keeping its core mechanics easy to follow while still offering enough variation to sustain longer sessions.

Drawbacks to weigh

Compared with later entries in the series, the original version has a lower winning ceiling and a more limited feature set.

FAQ: Big Bass Bonanza questions answered

What is the return-to-player rate in Big Bass Bonanza?

RTP is specified at 96.71%. Some sites set RTP at 95.67%. That configuration is chosen by the operator, not the player.

What is the free-spins allowance in the Big Bass Bonanza bonus feature?

The number of free spins depends on the float count: three award 10, four give 15 and five provide 20. Each set of four collected fishermen activates a ten-spin retrigger, with no more than three retriggers available.

Does Big Bass Bonanza offer direct access to the bonus round?

No bonus purchase is offered. Big Bass Bonanza provides free spins only when at least three scatter floats land in the base game, so the bonus round must be triggered naturally during play.

Which gameplay features distinguish Big Bass Bonanza from Big Bass Splash?

Big Bass Splash has a 5,000x ceiling compared with 2,100x, a bonus buy at 100x the stake, two scatter-assist features and three in-spin modifiers rather than the original’s single dynamite. Its money fish can also reach 5,000x per symbol.
