Bigger Bass Bonanza slot by Pragmatic Play — game artwork
Pragmatic Play · Big Bass series — the direct 2021 sequel to Big Bass Bonanza

Bigger Bass Bonanza

The “bigger” is literal, and the studio says so: Pragmatic’s own page calls this “this 4×5 edition of the classic fishing slot”. Twenty symbol positions against the original’s fifteen, 12 paylines instead of 10, and money symbols worth up to 4,000× rather than 2,000×.

What did not change is the 96.71% RTP — identical to the 2020 game. What did change quietly is the risk: both databases now call it High, where they split Medium and Med-High on the original. Bigger board, bigger symbols, harsher ride.

Worth a demo specifically to feel the extra row. A 5×4 board holds a third more money symbols on screen at once, which changes what a fisherman collect is worth when it lands — and changes how badly it stings when one does not. The maths you cannot check here is the RTP: Pragmatic ships this game in more than one configuration and the casino picks. This demo is part of our Pragmatic Play demo games library.

Top line pay4,000× total betA total-bet multiple, not a per-line figure like the Amusnet games on this site. SlotCatalog and VegasSlotsOnline both state 4,000×. Note that the SlotsLaunch feed’s own cap divided by the maximum bet gives 2,100× instead — a cross-check that reproduces the published figure on the other three Big Bass games and fails on this one. Two direct sources beat one derived number, so 4,000× stands, but we are not going to pretend the corroboration is as tidy as it was on the original.
JackpotNoneNo progressive jackpot. Neither the studio nor either database lists one, and SlotCatalog does tag a progressive where a game has one. Everything this slot pays sits inside the published RTP.

How Bigger Bass Bonanza Plays

Bigger Bass Bonanza is the direct sequel to the 2020 game that started the series, published by Pragmatic Play and developed by Reel Kingdom. The databases place it in autumn 2021 — SlotCatalog says 6 September, VegasSlotsOnline says 20 August, and Pragmatic publishes no date at all.

The headline change is the board, and it is officially stated. Pragmatic’s description opens: “Take to the seas in this 4×5 edition of the classic fishing slot.” Four rows, five reels — twenty symbol positions where the original had fifteen. SlotCatalog and VegasSlotsOnline both record the layout as 5-4, and both put the line count at 12 rather than the original’s 10. SlotCatalog’s minimum bet of 0.12 fits twelve lines at a penny each.

The feature is the same skeleton, unchanged. Three, four or five scatters award 10, 15 or 20 free spins. Money symbols land carrying cash values and pay nothing on their own. A wild collects every money symbol visible on the reels. Every fourth wild retriggers the round with ten more spins and steps the multiplier: 2×, then 3×, then 10×. Twelve wilds inside one round to reach the top step, exactly as before.

What the extra row actually does is hold more money symbols on screen at the moment a fisherman lands. That is the whole design change: the collect mechanic is untouched, but there is a third more board for it to sweep. Money symbols are doubled too, to a stated maximum of 4,000×.

The Story Behind Bigger Bass Bonanza

We reviewed the 2020 original last, so the interesting question here is what a year of iteration actually bought.

Not the return. Both games publish 96.71%, to the hundredth. Pragmatic did not adjust the payback when it enlarged the board — it moved the money around inside the same number.

Where it went is into the tail. The original’s money symbols topped out at 2,000× against a 2,100× ceiling. This one advertises 4,000× money symbols against a 4,000× ceiling. Roughly double the top end, on the same return — which means the money has to come from somewhere, and it comes from the ordinary spins.

The volatility labels confirm it. On the 2020 game the two databases we use disagreed: VegasSlotsOnline said Medium, SlotCatalog said Med-High. On this one both say High. Neither figure is official — Pragmatic publishes no volatility rating on any game in this series — but two sources moving in the same direction, on games that share a studio and a mechanic, is a meaningful signal.

So the sequel is not a bigger version of the same experience. It is the same return, redistributed towards a rarer and larger payout. Whether that is an upgrade depends entirely on what you came for.

Symbols and Paytable

Pragmatic publishes no symbol table for any game in this series. What follows is what the studio and the two databases actually establish.

The fisherman — wild, and the only thing that banks moneySubstitutes in the base game. In free spins he collects every money symbol visible on the reels. On a 5×4 board that is up to twenty positions of potential sweep, against fifteen on the original — the single biggest practical difference between the two games.
Money symbols — up to 4,000×Fish carrying cash values that sit inert until a fisherman lands. Pragmatic states the ceiling on one symbol as 4,000×, double the original’s 2,000×.
The scatterThree, four or five award 10, 15 or 20 free spins — official, and the same mapping as the 2020 game despite the larger grid. Note VegasSlotsOnline’s spec box claims this game has no scatter symbols, which is wrong and contradicted by its own review text.
The twelve linesTwo more than the original, bought by the extra row. Both databases agree on twelve; the official page states no line count at all.
What nobody publishesSymbol pay values, hit frequency, and any official volatility rating. Pragmatic gives you an RTP and a feature description and stops.

One number to read carefully. The advertised money symbol tops out at 4,000× and the game’s stated maximum win is also 4,000× — the two figures are identical. On the 2020 original there was a little headroom (2,000× symbol, 2,100× cap); here there is none published. There are two honest readings: either the ceiling genuinely is one money symbol, or the databases simply adopted the studio’s money-symbol figure as the max win. We cannot tell you which, and neither can they.

Bonus Features

🔢

A 5×4 board — officially the “4×5 edition”

Pragmatic’s own description names the change. Twenty symbol positions against the original’s fifteen, and 12 paylines instead of 10. It matters because the collect mechanic sweeps whatever is on screen: a third more board is a third more potential in the moment a fisherman lands.

💰

Money symbols doubled to 4,000×

The original stated 2,000×. This one states 4,000×, and the game’s published ceiling doubles to match at 4,000× your total bet. Same studio, same feature, twice the top end.

Same 96.71%, so the money moved rather than grew

Both games publish an identical return to the hundredth. Doubling the ceiling on an unchanged RTP means the extra value is funded from somewhere, and that somewhere is the ordinary spins. This is the trade the review is really about.

📈

Volatility stepped up to High

On the 2020 original our two sources split — VegasSlotsOnline said Medium, SlotCatalog said Med-High. On this game both say High. Pragmatic publishes no rating of its own for any game in the series, so this is two databases agreeing rather than a studio figure, but the direction is consistent with the maths above.

The feature itself is untouched

3/4/5 scatters for 10/15/20 free spins, wilds collect all visible money symbols, every fourth wild retriggers with ten more spins and a 2×, then 3×, then 10× multiplier. Word for word the original’s round. Reaching the 10× step still needs twelve wilds inside one feature.

No jackpot — the RTP covers everything

Like the rest of the Big Bass series, this game carries no progressive jackpot. Pragmatic lists none, VegasSlotsOnline lists none, and SlotCatalog — which does tag “Progressive Jackpot” on games that have one, including plenty in our library — does not tag it here.

That matters more than it sounds. On the Amusnet and EGT Digital games that make up most of this site, a chunk of every stake feeds Jackpot Cards or Bell Link, and the published RTP describes the reels rather than the whole product. Here there is nothing being skimmed: the 96.71% is the entire game.

The money-symbol collect can look like a jackpot round if you have only seen clips of it — cash values on the reels, a collect, a big total. It is not one. Those values are fixed multiples of your own stake, paid by the game, capped at 4,000×. Nothing pools, nothing accumulates across a network, and nothing fires at random.

The Gamble Feature, Properly Explained

There is no gamble feature on this game, and no source lists one. That is a standing difference between the Big Bass series and the Amusnet and EGT Digital catalogue that makes up most of this site, where a red-or-black card double-up appears in the studio’s own feature list on nearly every title.

There is no bonus buy either. The SlotsLaunch feed sets the flag to zero and SlotCatalog’s feature list for this game contains no Buy Feature — unlike Big Bass Splash, where it does. So feature entry here is earned on the reels only.

What you get is base spins, a scatter-triggered round and a collect mechanic. No side bets, no doubling ladder, nothing bolted on. On a High-volatility game whose return is already concentrated in one feature, having no way to gamble the small wins away is arguably a kindness.

What we like

  • A genuinely bigger board — 5×4 and 12 lines, stated by the studio itself
  • Money symbols and ceiling both doubled to 4,000× against the original’s 2,000×/2,100×
  • The same 96.71% return as the 2020 game, so the upgrade costs nothing in payback
  • No progressive skimming the RTP — the published figure describes the whole game
What to watch

  • The RTP is configurable: 96.71% published, 95.67% recorded live by SlotCatalog, and the casino chooses
  • Volatility moved to High on both sources — the doubled ceiling is funded by the ordinary spins
  • Our max-win cross-check fails here: the SlotsLaunch feed implies 2,100× where both databases say 4,000×
  • No official volatility rating, no official release date, and no paytable from anyone

How Bigger Bass Bonanza Compares

The series is the only fair comparison, because all four games share a studio, a mechanic and a multiplier ladder. Grids and lines are from the databases; money-symbol caps and RTP are from Pragmatic’s own pages.

GameYearGridLines / waysMoney symbolMax winRTP
Big Bass Bonanza20205 × 3102,000×2,100×96.71%
Bigger Bass Bonanza20215 × 4124,000×4,000×96.71%
Big Bass Bonanza Megaways20216 reelsup to 46,6564,000×4,000×96.70%
Big Bass Splash20225 × 3105,000×5,000×96.71%

Read the last column first. Three of the four games publish an identical 96.71%, and the Megaways build differs by a single hundredth. Pragmatic has not competed with itself on return at any point in this series — every game gives back the same amount.

So the columns that actually separate them are the middle ones. This game is the one that grew the board. The Megaways version grew the engine and kept the same 4,000× ceiling. Splash left the board alone entirely, went back to 5×3 and ten lines, and pushed the ceiling to 5,000× instead.

The pattern in the money-symbol column is worth noticing on its own: on the 2020 original the top symbol sat just below the max win, and on all three sequels the two figures are exactly equal. Either the ceiling is one symbol, or the databases took the studio’s number. Nobody publishes enough to settle it.

RTP, Volatility and Win Potential

The RTP of Bigger Bass Bonanza is 96.71% according to Pragmatic Play, printed under “Basic Game Info” on its official game page. VegasSlotsOnline states the same figure. It is identical, to the hundredth, to the 2020 original.

SlotCatalog states 95.67%, and flags the title with an RTP Ranges warning.

This is the same problem we documented on the original, and it applies to every game in this series. Pragmatic certifies more than one return configuration and the operator chooses which one to deploy. The studio’s page advertises the top build; a database that records what is live at casinos found a lower one. Both can be true at once, and there is no indicator in the game, no note in the paytable, and no way to tell from a demo — a demo runs whatever build that operator serves.

For scale: across the 44 official Amusnet spec sheets we have read for this site, the entire catalogue runs from 95.32% to 96.94%, a spread of 1.62 points between the worst game and the best. The gap between this one game’s two published figures is 1.04 points. Choosing the wrong casino costs nearly as much as choosing the wrong game.

The volatility is where this game genuinely differs from its predecessor. Pragmatic publishes no rating — none of the Big Bass pages carry one, which is a real gap next to Amusnet’s X-out-of-5 figures. But on the 2020 original our two databases disagreed, VegasSlotsOnline calling it Medium and SlotCatalog Med-High, whereas here both say High. That fits the arithmetic: the ceiling doubled while the return stayed still, so the distribution has to be thinner in the middle.

In practice, expect the same round you know from the original, on a board with a third more positions, paying out less often and larger when it does.

Bets, Bankroll and Session Planning

SlotCatalog gives a bet range of 0.12 to 240. VegasSlotsOnline’s spec box reads zero for both minimum and maximum, which is broken, so this is a single usable source and we would not treat it as the studio’s number. Pragmatic publishes no range at all.

The 0.12 minimum is a useful detail in itself: twelve lines at a penny each, which corroborates the twelve-line count both databases report and the official page omits.

The lines are fixed, so stake size is your only lever. What needs thought is session length rather than bet size. Everything worth having lives in the free-spins round, and the round is worth whatever the wild timing makes it worth — a board full of money symbols pays nothing until a fisherman lands. On a High-volatility build with a doubled ceiling, plan for the rounds that collect two small values and end, because there will be more of them than there were on the original.

Playing Bigger Bass Bonanza on Mobile

SlotCatalog records the game as JS/HTML5 at 15.1 MB, so it runs in a phone browser with no download — a little heavier than the original’s 13.7 MB, which is what the extra row costs.

The 5×4 grid is the one place where this sequel is slightly worse on a small screen than the game it replaced. Twenty positions with cash values printed on the fish is more to read at phone size than fifteen. It stays legible, but the original is the cleaner board if you play mostly on mobile.

Five Things to Know Before You Spin

  1. Ask which RTP build your casino runs. Pragmatic publishes 96.71%; SlotCatalog records 95.67% live. On this series that question is worth more than any strategy.
  2. The extra row is the whole upgrade. Twenty positions instead of fifteen means a fisherman collect sweeps more — that is what you are paying the extra volatility for.
  3. The 10× step still needs twelve wilds. Four per retrigger, three retriggers. The bigger board does not shorten the ladder.
  4. Read 4,000× as a total-bet figure. Nothing to divide, unlike the Amusnet games on this site — but note the advertised money symbol is also 4,000×, so the headline and the cap are the same number.
  5. If you want the original’s gentler ride, play the original. Same 96.71%, half the ceiling, and two sources that would not call it High.

Who Bigger Bass Bonanza Is For

Play it if you liked the original and want more of it in the literal sense. The board is a third larger, the money symbols are worth double, the ceiling is double, and the return is identical — you are not paying for the upgrade in payback. If the moment you enjoy is a fisherman landing on a screen full of cash values, this game gives you more screen for it.

Skip it if you want the steadier game. Both our sources moved this one to High volatility, and the arithmetic backs them: the same RTP with double the ceiling has to come out of the ordinary spins. The 2020 original is the gentler version of the identical idea. And skip it, as with every game in this series, if you cannot find out which RTP build your casino is running.

Bigger Bass Bonanza FAQ

What is the difference between Big Bass Bonanza and Bigger Bass Bonanza?
The board. Pragmatic’s own page calls this “the 4×5 edition” — five reels and four rows, twenty symbol positions against the original’s fifteen, with 12 paylines instead of 10. Money symbols are worth up to 4,000× rather than 2,000×, and the maximum win doubles to 4,000×. The RTP is identical at 96.71%, and the free-spins feature is unchanged.
What is the RTP of Bigger Bass Bonanza?
Pragmatic Play publishes 96.71% and VegasSlotsOnline agrees. SlotCatalog records 95.67% and flags the game as having configurable RTP ranges, meaning it ships in more than one certified build and the casino chooses. A full percentage point separates the two figures and nothing on screen reveals which one you are playing.
What is the maximum win?
4,000× your total bet, per SlotCatalog and VegasSlotsOnline. One caveat we would rather state than hide: the SlotsLaunch feed’s own cap divided by the maximum bet gives 2,100× instead. That derivation reproduces the published figure exactly on the other three Big Bass games and fails only here, so we go with the two direct sources — but the corroboration is not as clean as it was on the original.
How do the free spins work?
Three, four or five scatters award 10, 15 or 20 free spins. Money symbols land carrying cash values and pay nothing until a fisherman wild appears, at which point he collects every money symbol visible on the reels. Every fourth wild retriggers with ten more spins and raises the multiplier: 2×, then 3×, then 10×. Reaching the top step needs twelve wilds in one round.
Is Bigger Bass Bonanza more volatile than the original?
By the labels, yes. SlotCatalog and VegasSlotsOnline both call this one High, where on the 2020 game they split Medium and Med-High. Pragmatic publishes no volatility rating for any game in the series, so that is two databases agreeing rather than a studio figure — but it fits the maths, since the ceiling doubled while the RTP stayed the same.
Does it have a jackpot or a bonus buy?
Neither. There is no progressive jackpot on any Big Bass game, and no buy feature on this one — the SlotsLaunch feed sets the flag to zero and SlotCatalog lists no Buy Feature, unlike Big Bass Splash where it does. Feature entry is earned on the reels.
When was Bigger Bass Bonanza released?
Pragmatic publishes no date. SlotCatalog says 6 September 2021 with a wide release on the 16th; VegasSlotsOnline says 20 August 2021. Two secondary sources about three weeks apart, so autumn 2021 is as precise as we would be.
How many paylines does it have?
Twelve. SlotCatalog records “Betways: 12” and VegasSlotsOnline describes a 12-payline layout; the official page states no line count. SlotCatalog’s minimum bet of 0.12 fits twelve lines at a penny each, which is a small independent check on the figure.

Our Verdict

8.5/ 10

The same game with a bigger net, and a sharper edge

Bigger Bass Bonanza does exactly what its name promises and, unusually, the studio spells it out: Pragmatic’s own page calls it “the 4×5 edition of the classic fishing slot”. Twenty symbol positions instead of fifteen, twelve paylines instead of ten, and money symbols worth up to 4,000× where the original stopped at 2,000×. The maximum win doubles to match. The feature underneath — scatters for spins, wilds collecting every money symbol, a 2×/3×/10× retrigger ladder needing twelve wilds — is untouched.

The part worth thinking about is what stayed the same. Both games publish 96.71%. Pragmatic doubled the top end without moving the return, which means the extra value is funded out of the ordinary spins — and both databases duly moved their volatility label from Medium-ish to High. This is not a bigger version of the original’s experience. It is the same money, redistributed towards a rarer, larger outcome.

We rate it 8.5, a notch above the original, because the upgrade is real and costs nothing in payback. Two things keep it from going higher. The first is the series-wide problem: the RTP is configurable, SlotCatalog records 95.67% against the studio’s 96.71%, and the casino decides which you get. The second is smaller but worth your knowing — our max-win cross-check, which reproduces the published figure on the other three Big Bass games, fails on this one, giving 2,100× where both databases say 4,000×. We go with the databases, and we tell you the check disagreed.

If you want this feature at its gentlest, the 2020 original is still there at the same return. If you want it at its largest, Big Bass Splash reaches 5,000× on a smaller board. This is the middle of the series, and a good place to be.
