Which Big Bass Slot Is Best? Every Tested Edition in One Table

What every Big Bass slot has in common

Strip the artwork and every edition runs the same engine. Fish land on the reels carrying a cash value. The fisherman is a wild that appears only in free spins, and when he lands he collects every fish on the screen. In the original design, four fishermen add ten spins and step the collection multiplier up, 2x, then 3x, then 10x; three, four or five scatters open ten, fifteen or twenty spins. The line pays exist, but they are small change. The feature is a collector, and the base game is the price of admission to it.

The logs put a number on that. Across the three runs of Big Bass Bonanza logged in September 2026, the fisherman’s collections were 94% of everything the feature paid: 650 collections over 251 bonuses. Christmas Big Bass Bonanza, published on 26 September, gave the same 94% to Santa’s collections and 6% to paylines. In the first runs, published in September 2026, Reel Action split USD 9,782 collected against USD 528 from lines and Floats My Boat USD 9,467 against USD 161, and in Big Bass Splash 92% of what the bought features paid came through collections. Whatever a sequel adds, it adds around that collector, and the questions worth asking about any edition are the ones the collector answers: how often the feature opens, how far it runs, and what the fisherman finds when he arrives.

The table: every tested Big Bass slot

The table below is the lab’s register filtered to one family. Each row is one game with the figures its logged runs produced: measured return next to the studio’s declared figure, the share of rounds that paid anything, the largest ordinary round, what the bought feature returned against its price, natural bonuses per thousand rounds, and the longest run of blank spins. A column heading sorts by that column; a row opens the full review with its logs. Editions arrive here the day their test is published, so the list will outgrow the prose around it, and the note under the table names the test set that built it.

Two things the columns cannot show. First, a row can rest on a single run: on 16 October 2026 three of the thirteen did, and the other ten pooled two or three; the family so far holds 36 runs across 21 games and 360,000 logged rounds, and a single run of a game whose return arrives through rare 500x features carries a wide band, printed on every review. Second, the declared RTPs in this family sit within a point of each other, from 96.06% to 96.72%, so the measured column is a record of what happened in each run, not a league table of generosity.

Which Big Bass slot has the best RTP?

Asked of the rules screens, the question has a flat answer: the tested editions are declared between 96.06% and 96.72%, and the original Big Bass Bonanza, at 96.71%, sits near the top of that narrow range with several of its sequels. Asked of the logs, the answer moves with every run. Across 21 tested editions the measured average is 93.4% against a declared average of 96.41%. The highest measured return belongs to Big Bass Bonanza Megaways at 106.5%, the lowest to Big Bass Bonanza 1000 at 72.8%, and 15 of 21 editions finished under their printed figure.

That spread is the family’s character, not a ranking. Bigger Bass Splash measured 98.52% in the run published on 8 September 2026 because four features paid above 500x; without those four rounds the same run would have returned about 65%. Big Bass Bonanza returned 81.19%, 96.83% and 81.23% in three sessions of the same build. An edition with a higher measured RTP is one whose run caught more of the fisherman’s good days; the design value is printed on the rules page, and it is nearly the same across the family. 19 of 21 measured bands contain the declared figure, which is what a fairly declared set of finite runs looks like. The one that did not, at the time of writing, was the pooled Big Bass Bonanza series: three runs together at 86.41%, with a band that stopped short of 96.71%. That is a case for a fourth run, not a verdict. On 22 October 2026 a second joined it: the first run of Big Bass Bonanza 1000 returned 72.76%, and its band of 58.12 to 87.4% stops short of the printed 96.51% as well, on one run rather than three.

The hit rate tells a quieter story. Reel Action, whose paytable adds a two-float award worth half a stake, paid on 21% of rounds in the run published on 15 September 2026, the highest in the family at that date; the other editions sat between 11 and 16%, one paying round in seven or eight. The longest blank stretch in the family belongs to Bigger Bass Blizzard Christmas Catch, at 80 rounds without a win.

Which edition triggers free spins most often?

The family triggers on a narrow band. The median tested edition opens its feature once every 120 rounds; the most frequent, Big Bass Mission Fishin, once every 100, and the least frequent, Big Bass – Hold & Spinner, once every 230. The interval is an average; the longest gap column is the number that decides a session, and the longest wait between two natural features in the family so far is 1,264 rounds, in Big Bass – Hold & Spinner. Editions with a second bonus, such as the coin respins of Hold & Spinner, are counted here on free spins only; the second feature has its own rhythm and its own paragraph in the review.

Frequency and payout pull against each other here too, but gently. Because every edition pays its feature through the same collector, the most frequent editions pay their feature only a little less on average: the natural bonus in the family averaged 71 bets, and the gap between the top and the bottom of the payout column is well under a factor of two, where across the whole lab it is more than ten. What separates a feature from another feature is the retrigger. The 2x and 3x stages live in features that reach twenty or thirty spins, and in the run published on 26 September 2026, Christmas Big Bass Bonanza paid 45x on average for a feature that ended at ten spins, 83x for one that reached twenty, and 240x for the six that ran to thirty.

Is buying the bonus worth it in Big Bass slots?

18 of the tested editions sell the feature at a hundred times the stake and 3 do not; the demo builds of the original Big Bass Bonanza, of Big Bass Bonanza Megaways and of Bigger Bass Bonanza have no purchase at all, so every one of their features had to be waited for. Across the editions with a button, the average series returned 0.88x of its price, 4 of 18 series finished above the price, and 79% of individual tickets returned less than they cost. The strongest series in the family belongs to Big Bass Floats My Boat at 1.17x of price, the weakest to Big Bass Halloween 2 at 0.42x.

The median column is the one to read. Even the series that finished ahead did so on a handful of tickets. In Big Bass Day at the Races, published on 16 September 2026, the purchases returned 1.21x of price on average while the median ticket paid 0.52x and 35 of 50 lost money; in the first Reel Action series, published on 15 September 2026, the five largest tickets supplied USD 7,560 of the USD 11,959 returned. The fisherman’s payout has the same shape whether the feature was bought or triggered: most visits find a few small fish, and the average is made by the rare feature that runs to thirty or forty spins with the multiplier up. A purchase buys the visit, not the fish.

What the sequels changed, edition by edition

Figures in this section come from the runs as logged on the dates shown, and do not update; the table above does.

Big Bass Bonanza (2020) and Christmas Big Bass Bonanza (2020)

The template and its first repaint. The original’s demo build has no purchase and no ante, which makes it the cleanest measure of the collector on its own: 251 natural features over three runs, one per 120 rounds, 94% of the feature money through the fisherman. The Christmas edition swaps him for Santa and changes nothing underneath. Its first run, published on 26 September 2026, closed within a point of the declared figure, and its most telling number is a negative one: a 2,000x fish, the largest value in the rules, surfaced thirteen times in that run and was never on the screen at the same moment as a collector. A second run, logged on 30 September, returned 103.61%.

Big Bass Bonanza Megaways (2021)

The grid becomes six reels of variable height with an extra row over the middle four, up to 46,656 ways, and wins tumble. The change that matters is small print: fish survive a winning tumble in free spins and stay for the fisherman. In the run of Big Bass Bonanza Megaways published on 10 September 2026 the feature opened 88 times, one per 114 rounds, 23 of them retriggered, and none reached the 10x stage. Like the original, this build sells no feature.

Big Bass Splash (2022) and Bigger Bass Splash (2025)

Splash adds a set of modifiers drawn before the feature opens, a scatter respin that nudges a third scatter into place, and a fish worth 5,000x. The modifiers describe the conditions of a feature rather than its result: in the run published on 10 September 2026, two purchases each received four modifiers and paid USD 563 and USD 29. Bigger Bass Splash keeps the mechanics and turns the volatility up. Its first run, published on 8 September 2026, held four features above 500x, one of them a 48-spin feature that collected seventeen times for 1,171x, and measured 98.52% while the base game on its own returned 30% of stake; the second, logged on 29 September, returned 108.41% with a 1,225.8x feature.

Big Bass Keeping it Reel (2022)

A golden fisherman and a net. Fish that escape the reels drop their value into a net that shrinks as it waits, and only a golden fisherman collects it; nothing left in the net is paid when the feature ends. In the run of Keeping it Reel published on 11 September 2026, the net supplied USD 3,786 of the natural features’ money, a golden fisherman paid USD 75.60 from it on a screen with no fish at all, and one feature ended with USD 484 still displayed in the net and USD 126 actually paid.

Keeping it Reel is also the edition that stayed far from its printed 96.07% across a second run. That run, logged on 15 October 2026, returned 89.09% after 83.55% in the first, and together the 20,000 rounds came to 86.32%, the lowest pooled return in the family, with a band of 72.5 to 100.14% that still contains the printed figure. Its largest round in the second run was a 571.1x feature, and its fifty purchases returned 0.77x of the price on a 0.41x median.

Big Bass Hold & Spinner (2023)

The first edition with a second bonus: money symbols lock in place and respin, and the coins that opened the feature are paid again with every new hit. In the run of Hold & Spinner published on 11 September 2026, the coin bonus opened 36 times and paid USD 3,624 in total, while the fisherman’s free spins opened 45 times and paid USD 5,800, including an 800x feature that reached the 10x stage. In that run the new mechanic did not take over from the old one, and its free-spin drought between rounds 7793 and 9057 was, at the time of writing, the longest in the family; in the second run, published on 5 October 2026, the coin bonus paid USD 8,058 against USD 7,360.80 from natural free spins.

Big Bass Amazon Xtreme (2023)

A pick screen before the feature: unopened positions reveal extra spins, guaranteed fish, fishermen already on the meter, or a boot that ends the picking. The cap rises to 10,000x and the volatility label on the rules page says low. The run of Amazon Xtreme published on 9 September 2026 recorded 72 consecutive rounds without a win, one paying round in eight, and a purchase series that lost USD 1,810 despite one ticket paying USD 1,231.

Big Bass Floats My Boat (2024)

Positions on the grid remember. A fish that lands on a cell and is not collected raises that cell’s multiplier, and a later fish on the same cell pays the multiple when a fisherman finally arrives. In the run of Floats My Boat published on 15 September 2026, one feature paid USD 154 from fish whose printed values summed to USD 92, and 647 feature screens showed fish with no collector; the multiplier stayed, the fish did not. Money collection also happens in the base game here, 190 times in that run for USD 3,858.

Big Bass Day at the Races (2024)

Horses replace the pick screen. Modifiers drawn before the feature can prefill the collector meter, add starting spins or guarantee a money symbol on every spin, and the multiplier ladder runs to eight levels and 50x. Base-game collections exist too, 203 of them in the run of Day at the Races published on 16 September 2026. The same run recorded a 901-round wait for a feature and the strongest purchase series in the table at that date: 1.21x of price on the mean, 0.52x on the median.

Big Bass Bonanza Reel Action (2024)

The fisherman counts toward the next extension even when the screen holds no fish, so the meter can fill on an empty catch. In the run of Reel Action published on 15 September 2026, 57 feature screens had a fisherman and no money fish, and one feature earned ten extra spins at 2x that then added USD 0. All three declared RTPs of this build, ordinary play, ante and purchase, are the same 96.50%, and its purchase series returned 1.20x of price on the mean with a 0.37x median.

Big Bass Halloween 2 (2024)

Halloween 2 repaints the Big Bass Splash ladder rather than changing it: its chainsaw does the bazooka’s job, replacing every symbol except the Fishermen when a Fisherman lands without fish, and the five pre-round modifiers and the 2x, 3x and 10x tiers are the same. In the run logged on 4 October 2026, round 185 used that replacement to produce USD 62 in fish values on its twelfth free spin. The Fisherman collected USD 124 at the existing 2x rate, and only the next twelve-spin batch used the newly earned 3x tier. In round 3072 three Fisherman retriggers took a twelve-spin opening to 48 spins and USD 451.20, with the +2 modifier adding two spins to each batch; a shorter 30-spin feature paid USD 621.20. The 87 natural features contained USD 10,362 in fish collections and USD 781.40 from paylines, while the separate fifty-ticket purchase sample returned 41.72% of its cost.

Big Bass Vegas Double Down Deluxe (2024)

Double Down Deluxe keeps the Splash ladder of 2x, 3x and 10x and its hook, dynamite and bazooka, but splits the collector in two: blue and red Fisherman Wilds fill separate trails, four of one colour add ten spins and raise only that colour’s rate, and both can collect the same fish on one spin. The raised rate also starts at once rather than after the current batch: in the run logged on 5 October 2026, blue reached 2x on the eighth free spin of purchase 5 and on the ninth took USD 16 from USD 8 of fish while red took USD 8 at 1x, one of only two such split-rate spins among 2,895 logged. Scatters award 15, 20 or 25 spins and Splash’s pre-round modifiers are gone; 27 of the 83 natural features were extended, and fifty regular purchases returned 115.94% of their cost on a median ticket of 0.486x.

Bigger Bass Bonanza (2021)

Four rows and twelve paylines instead of three and ten, the same ladder of a fourth, eighth and twelfth fisherman for 2x, 3x and 10x, and a top fish of 4,000x, which is also the cap. The demo build, like the original’s, sells no feature. In the run of Bigger Bass Bonanza published on 22 October 2026, 78 natural features came once per 128 rounds and paid 66.95% of all money; two of them collected twelve fishermen, ran the full 40 spins at 10x and paid 603x and 456.5x, 16.8% of the feature money between them, while 45 of the 78 never reached a fourth fisherman. The 4,000x fish was on a free-spin screen three times and never under a collector, and the run measured 94.11% against 96.71% declared.

Big Bass Bonanza 1000 (2025)

The original’s reels and ladder with the money values reshuffled: the fish are worth 2x to 50x the bet plus a 1000x value, the cap rises to 20,000x, and the build adds an Ante Bet, a 100x purchase and a 450x Super Free Spins purchase in which the 1000x fish is more frequent. In the run of Big Bass Bonanza 1000 published on 22 October 2026 the 1000x fish was on the screen 56 times, 36 of them in the base game where nothing collects it, and was caught once, on a bought ticket, for USD 2,024 at a USD 2.00 stake; the 69 natural features averaged 57.8x a round, the fifty 100x purchases returned 0.93x of their price on a 0.4755x median, and the run measured 72.76% against 96.51% declared.

Big Bass Halloween (2023)

The first Halloween repaint keeps the original’s ladder of 2x, 3x and 10x, prints a 2,000x fish and sells the feature for 100x the bet. In the run of Big Bass Halloween published on 29 October 2026, a fisherman collecting at 1x took USD 39.62 on average in the 98 natural features and USD 20.97 in the fifty bought ones, where 71.0% of the fish on the screen were worth 2x or 5x; the four purchases that reached the 10x stage supplied 59.2% of the bought feature money. The 2,000x fish was on a free-spin screen nine times and never under a collector.

Big Bass Mission Fishin’ (2024)

Every feature opens with a choice of mission: FREE SPINS with the fisherman, or STACK THE CASH, a respin round of sticky fish coins banked on robo-crabs under the reels. Our run took the free spins every time, so only they are measured. Six TOP SECRET folders then hand out upgrades until a boot turns up, and the one that counted was START FROM LEVEL 2, which opens the round at the 2x stage. In the run of Big Bass Mission Fishin’ published on 29 October 2026, it came up in 26 of the 100 natural features, which averaged 91.9x the bet against 51.3x for the rest; the fifty 100x purchases returned 0.78x of their price, and a single ticket that reached 10x paid USD 2,678 of it, 34.5% of the total.

Big Bass Splash 1000 (2025)

Splash’s pre-round modifiers, its hook, dynamite and bazooka and the 2x, 3x and 10x ladder stay; the fish become worth 2x to 100x the bet plus a 1000x value, the cap rises to 25,000x, and the build adds an Ante Bet, a 100x purchase and a 450x Super Free Spins purchase. In the run of Big Bass Splash 1000 published on 5 November 2026 the number of modifiers drawn did not order the results: the 25 natural features that drew none averaged 49.00x the bet, the seven that drew three 109.53x and the two that drew four 37.40x, and the best of the fifty purchases, USD 957.40 over 50 spins, drew none at all. The 1000x fish showed on a natural free-spin screen five times and was never collected; the run measured 87.72% against 96.52% declared, and the purchases returned 0.82x of their price on a 0.516x median.

Big Bass Secrets of the Golden Lake (2024)

Every feature opens with twelve face-down cards: a BONUS card plays the regular free spins, a SECRETS OF THE GOLDEN LAKE card a version whose reels carry only fish, fishermen and blanks, and the build sells the regular route at 100x and Golden Lake directly at 270x. In the run of Secrets of the Golden Lake published on 5 November 2026 the rig always took the first card, and it showed Golden Lake in 8 of 141 features, although each deck, once turned over, held two such cards among twelve; the four natural Golden Lake rounds included the best of the series, 551x over 30 spins, and brought 16.4% of the natural feature money. Fish worth 2,500x and 5,000x appeared on free-spin screens and none was collected, the fifty 100x purchases returned 0.88x of their price on a 0.482x median, and the run measured 82.15% against 96.07% declared.

Big Bass Christmas Bash (2023)

The Christmas Bash keeps the 5×3 board and ten lines and puts an ice-fishing scene in front of every feature: it draws anywhere from none to five modifiers, START FROM LEVEL 2, +2 SPINS, MORE FISH, MORE FISHERMAN and a raised chance of dynamite, hooks and bazookas, while fish tags reach 5,000x the bet and a round closes at 5,000x. Across the three runs of Big Bass Christmas Bash published on 7 November 2026, 212 of the 280 natural features drew at least one modifier, and the 85 that opened at the 2x stage averaged 116.55x the bet against 53.89x for the other 195. Round 230 of the second run, 1,377x over 36 spins with all five modifiers lit, took that run to 119.81%, against 96.59% and 93.19% for the others and 96.71% declared; without it the other 29,999 rounds returned 98.61%. Bought rounds drew a modifier in only 75 of 150, against three in four natural features, and returned 76.65% of their cost.

Bigger Bass Blizzard Christmas Catch (2022)

The Blizzard edition moves to five reels of four rows and 12 lines, lets the snowmobile rider pay for a pair, and keeps the ladder of ten extra spins and a 2x, 3x and 10x collect for every fourth fisherman, with fish worth 2x to 50x the bet plus a rare 4,000x value; its EXTRA CHANCE switch raises the bet to 18x and turns the purchase off. In the three runs of Bigger Bass Blizzard Christmas Catch published on 6 and 7 November 2026, the fisherman’s collects made up 94.4% to 96.5% of what natural free spins paid, yet the 10x stage came five times in the first run, once in the second and never in the third, 6 of 273 natural features in all, and the 4,000x fish was never collected. Returns fell from run to run, 114.07%, 103.02% and 95.41% against 96.08% declared, while the 150 purchases at 100x came to 0.95x of their price, the best ticket at 14.29x.

So which Big Bass slot is best?

It depends on what the question is really asking. For the most frequent feature, the bonus column of the table answers today, and so far the answer has been the tumbling Megaways build, with the original and its Christmas and Splash editions a few rounds behind. For the highest ceiling, Big Bass Bonanza 1000 at 20,000x since its test on 22 October 2026, whose first run topped out at 405x, and before it the editions capped at 10,000x: Amazon Xtreme, Day at the Races, Hold & Spinner and Keeping it Reel, and the first round among those four above a tenth of the cap came in the second run of Day at the Races, logged on 14 October 2026, at 1,075.8x. For the largest round actually logged in the family, Big Bass Floats My Boat at 1,991x. For a purchase that pays for itself, no edition: every series in the family has a median ticket under the price, and the ones that finished ahead did so on a few tickets each. For the collector at its simplest, the original, which sells nothing and lets the wait do the work, or Bigger Bass Bonanza, which adds a fourth row and twelve lines and sells nothing either.

What the logs do not support is the idea that one edition is set looser than another. The declared figures are a point apart, the fisherman is the same fisherman, and the runs differ by what he found. The honest way to choose is by the mechanic worth watching for a few hundred rounds, not by a measured RTP that the next run will move.

Big Bass slots the rig has not tested yet

Pragmatic Play’s demo catalogue, read on 29 September 2026, lists twenty-three titles carrying the Big Bass or Bigger Bass name, and three that it did not carry were added to the rig’s list by hand, Bigger Bass Bonanza and Big Bass Bonanza 1000 on 22 October 2026 and Big Bass Splash 1000 on 28 October; 21 of the twenty-six have a published test. The rest are queued: Big Bass Bonanza 3 Reeler, Big Bass Hold & Spinner Megaways, Big Bass Raceday Repeat, Big Bass Xmas Xtreme, and Big Bass: Return to the Races.

Each of those tests, once published, joins the table above and every figure on this page that carries the live-data badge; the paragraphs about individual editions are extended by hand and dated when that happens. Two numbers are worth watching as the family fills in. The measured average should keep drifting towards the declared average as runs accumulate, and the share of purchase series above the price should shrink as tickets accumulate, because the purchase RTP of these builds is the same figure as their ordinary RTP and a short series of tickets cannot beat it for long; on 16 October 2026 four of the eleven series stood above the price. If an edition holds a measured return far from its declared figure across a second run, that edition gets a re-test and a paragraph here.
