Stakes multiplied by this interval measure gross wagering, not the net cost of obtaining a bonus. Purchase returns above include the complete purchased round and are divided by the ticket price.

How it plays
8 rules screens from the game
A 5x4 board with twelve fixed paylines, evaluated from reel one outward. The boat is the premium: 200x the bet for five and the only picture that pays for two. Fish are the money symbols and carry a value from 2x to 5,000x the bet at every spin, but outside the feature they are just another 3, 4 or 5-of-a-kind symbol; the printed value matters once the fisherman is on screen, and he appears on the reels during free spins only.
The bass scatter lands on any reel. Three start 10 free spins, four give 15, five give 20. Two scatters without a third can trigger a respin: reels holding scatters shift down one row, the others spin again, or a hook pulls a reel up to reveal another scatter. The first run's log recorded 226 such respins in ten thousand spins, and they cost nothing.
Inside the feature every fisherman collects the value of every fish on the screen. Each fourth fisherman collected adds 10 spins and raises the collection multiplier, to 2x at the second level, 3x at the third and 10x at the fourth, after which the round cannot extend further. Before the round starts, up to five modifiers may be drawn: more fish, more fishermen, more hooks, dynamite and wipeouts, a start at level two, or two extra spins on the round and every retrigger. Dynamite drops fish onto a fisherman-only screen, a hook pulls a fisherman onto a fish-only screen, a wipeout clears everything except the fishermen.
Two purchases sit on the left panel: 100x the bet for the standard feature and 350x for a super version; the lab bought only the standard one. An ante bet at 1.5x the stake raises the scatter frequency; the rules quote 96.5% for every mode and cap a round at 5,000x.

Verdict
Six features past 500xSix rounds above 500x in 20,000 spins is the number this page turns on: 1,171.1x, 1,003.4x, 689.6x and 526.8x in run one, 1,225.8x and 829.2x in run two, all of them fisherman features, while no scatter-free spin passed 50.2x in either run. The runs returned 98.52% and 108.41%, 103.47% pooled over 20,000 rounds with an approximate 95% CI of 78.82 to 128.12%, wide because so much of the money sits in those six rounds; the combined balance closed 694 stakes up.
The feature paid 71.3% of everything returned: 170 triggers, one per 118 spins, 8.5 bHz (bHz: natural features in every 1,000 rounds), 86.83x on average and 38.1x at the median, 34 rounds above 100x, 36 under 20x and none under 10.2x; 43 of the 170 extended past their opening award, and the bought and natural rounds alike ran about fourteen spins on average, 14.6 and 14.2. Between features the reels returned little: hits on 15.56% and 15.32% of spins, a 1.0x median win, 16,912 blank rounds, and 96 dry stretches of at least twenty spins, 49 the longest, in run two.
One hundred tickets, USD 200 apiece, returned 0.974x of price, 97.38%, split 1.0672x and 0.880x by run, and USD 82 as the median ticket in both runs: 80 tickets lost money, 20 covered the price, six went past 2x and two past 5x, purchase 46 of run one at 21.468x and purchase 31 of run two at 16.845x, both 48-spin rounds. Fish collections supplied USD 19,026 of the USD 19,475.40 the tickets returned, line wins USD 449.40, so a ticket is a bet on fishermen turning up: 26 of the 100 bought rounds extended, and the typical ticket came back with two fifths of its price.
- Six fisherman features past 500x in 20,000 spins, 1,225.8x and 1,171.1x at the top
- Features came once per 118 spins, 8.5 per 1,000 rounds, and 43 of 170 extended
- The smallest of 170 natural features still paid 10.2x, and the pooled feature median was 38.1x
- Run two lost no 100- or 200-stake test bankroll across 10,000 spins
- The base reels returned a 1.0x median hit and never passed 50.2x on a single spin in 20,000
- Ninety-six dry stretches reached 20 spins in two runs, the longest 49
- Four tickets in five came back below their price, and only two of 100 passed 5x
- Neither the 350x super purchase nor the 1.5x ante has been measured in two runs
Run 01·2026-09-08·98.52%
Split the run into the base game and the feature and the design is plain. Base spins alone returned 30.03% of stake, 84.4% of them paid nothing, and 43 separate stretches of twenty or more blank spins appeared, the longest 43 spins from round 955 to 997. The feature returned 68.5 points on top, so this is a game you play for the trigger and nothing else.
When the trigger came it came often: 76 rounds, one per 132 spins, no gap longer than 612 spins (rounds 764 to 1376). Half of them paid under 37.4x, but eleven paid over 100x and four crossed 500x: 1,171.1x on round 5505, 1,003.4x on 4091, 689.6x on 2865 and 526.8x on 7937. The 5505 round ran 48 spins, collected fish seventeen times and took 2,326 from a 2.00 stake; it lifted the balance to its peak of 1,240 bets up, and the run still finished 148 bets under the start because the base game ate the rest.
All three test stakes went early: 50 bets by spin 186, 100 bets by spin 237, 200 bets by spin 671. The trough was 1,147 bets down on spin 2684, before the big rounds arrived. Anyone playing Bigger Bass Splash at 200 bets is playing for a bonus that, on this sample, is more likely to pay 37x than 500x.
The purchase route shows the same skew. Fifty buys at 200.00 returned 1.07x on average, a profit on paper, but the median was 0.417x and 40 of 50 lost money. One buy, number 46, ran 48 spins and returned 21.5x; the other 49 returned 0.65088x their combined price. Bought rounds gained spins after entry in 13 of 50 cases and collected 5,223 bets' worth of fish in total.
Run 02·2026-09-29·108.41%
The second session never fell far: the low was 72.1 stakes down on spin 2258, the 100- and 200-stake test bankrolls survived all 10,000 spins and only the 50-stake one ran out, on spin 2226, and the balance peaked 2,072.6 stakes up on spin 5914 before closing at USD 101,682.80, 841.4 stakes ahead, 108.41% of the USD 20,000 staked; block by block of 2,000 rounds the figures were 102.9%, 169.9%, 127.2%, 50.5% and 91.6%. Between features the reels were bare: a hit on 15.32% of spins with a 1.0x median, 8,468 rounds paying nothing, 53 blank stretches of twenty spins or more, the longest 49 from round 6688, and no scatter-free spin above 50.2x.
Ninety-four features arrived one per 106 spins, 9.4 bHz, and paid USD 15,823.40 over their rounds, 73.0% of the return, 84.17x on average and 42.9x at the median: 23 cleared 100x, 18 stayed under 20x, none paid less than 10.2x, and 25 of the 94 gained spins from collected fishermen. Round 3561 ran forty spins to USD 2,451.60, 1,225.8 stakes, the largest round on the page, and round 5150 ran thirty to 829.2x; the next were 289.4x on round 2915 and 280.7x on round 8746, and the widest gap between triggers ran 507 spins, from round 6281 to 6789.
Purchases came to fifty at USD 200 and returned USD 8,803.20, 0.880x of price, 88.03%, with USD 82 as the median payout: 40 lost money, 10 covered the price and one, purchase 31, ran 48 spins to USD 3,369, 16.845x, the only ticket past 2x; the worst, purchase 20, paid USD 10.40. Thirteen bought rounds extended past their opening award, the average bought round lasted 14.4 spins, and fish collections supplied USD 8,580 of the USD 8,803.20, with line wins adding USD 223.20.

Corrected 29 September 2026: this run was recorded by an early rig that lost the last free spin of a feature, so fisherman collections on that spin were missing from 12 natural features and 7 purchases. Natural collections rise from 232 to 244 and the average bought collection from USD 201.88 to USD 208.92. Round wins, the RTP and the trigger count are unchanged, and the published spin log keeps the figures as first recorded.

On 29 September the second run returned 108.41% after 98.52% on 8 September, and the two runs pooled stand at 103.47% over 20,000 rounds. Free spins came more often, 94 triggers against 76, one per 106 spins against one per 132, and the two biggest rounds on the page now sit in different runs, 1,225.8x here and 1,171.1x there; the purchases fell from 1.0672x to 0.880x of price, with one 16.845x ticket against one 21.468x.
2 test runs combined into one sample (2026-09-08, 2026-09-29): 20000 ordinary paid rounds, including naturally triggered features, at a fixed USD 2.0 bet; 100 bonus buys at 200.0 each (100.0x) on the official Pragmatic Play demo server (jurisdiction 99, RTP profile 96.5%); every request and response logged.

FAQ
6 questions · answered from the logHow did two runs of Bigger Bass Splash compare?
98.52% then 108.41%, 103.47% pooled over 20,000 rounds; the second run drew 94 features against 76 and its balance never fell more than 72.1 stakes below the start, while the first sank 1,146.8 stakes at spin 2684. Both hit on 15.56% and 15.32% of spins at a 1.0x median, and each produced a feature above 1,100x.
Which fisherman rounds paid over 500x?
Six in 20,000 spins: 1,171.1x on round 5505, 1,003.4x on 4091, 689.6x on 2865 and 526.8x on 7937 of run one, then 1,225.8x on round 3561 over forty spins and 829.2x on round 5150 of run two. No scatter-free spin in either run beat 50.2x.
What were the longest droughts between features?
One per 118 spins over 20,000, 8.5 per 1,000 rounds; the longest gaps were 611 spins in run one, from round 764 to 1376, and 507 in run two, from 6281 to 6789. The first run also logged 226 free scatter respins, the nudges and hooks that try to complete a trigger.
Do the purchases pay for themselves?
No. Typical tickets fell short: 100 buys at USD 200 came back at 0.974x of price, 97.38%, and the middle ticket returned USD 82 in both runs, with 80 losing tickets. The average holds up on two 48-spin rounds, purchase 46 of run one at USD 4,293.60 and purchase 31 of run two at USD 3,369; fish collections were USD 19,026 of the USD 19,475.40 returned.
What does a retrigger look like in Bigger Bass Splash?
Each fourth fisherman collected extends the round by ten spins and moves the collection multiplier up a level, so a round grows in steps: 43 of 170 natural features and 26 of 100 bought ones extended past their opening award, and the longest rounds on the page ran 48 spins, three natural ones in run one and one purchase in each run. Opening awards ran 10, 12, 15, 17 or 20 spins depending on scatters and the extra-spins modifier.
Why does one run of 10,000 spins swing so much?
Because six rounds carry so much of the return: a 10,000-spin sample swings on whether a 1,000x fisherman round lands. Run one had two rounds above 1,000x and finished at 98.52%; run two had one and finished at 108.41%, with 94 features against 76.
