One ticket equals 100 ordinary stakes. Natural bonuses occurred once per 118 ordinary rounds in this sample. 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
7 rules screens from the gameBig Bass Splash uses five reels, three rows and ten fixed paylines, with a line connecting matching symbols from the left edge. Most symbols need three matches; the truck also pays for two. At the USD 2 stake shown in the rule captures, five trucks on one line pay USD 400 before any separate money collection. Fish have two jobs: they complete ordinary paying lines, and their displayed cash values can be collected during free spins.
The fisherman is the wild and can appear on any reel during the feature, substituting for paying symbols and collecting the values of all fish visible on that screen; several fishermen collect the same fish. Fish values range from 2x to 5,000x the spin stake, while the complete round is subject to the game's win cap. Three scatters start ten free spins, four start fifteen and five start twenty. Two scatters in ordinary play can sometimes receive help, a downward nudge with a respin or a hook pulling a reel upward, but two scatters alone do not guarantee a feature.
Before free spins begin, the game randomly assigns between zero and five modifiers. They can put more fish or more fishermen on the feature reels, increase the chance of dynamite, hook and bazooka events, begin at collection level two, or add two spins. The extra-spins modifier adds two to the starting award and to every later retrigger. These are automatic selections with no player choice.
Each group of four fishermen advances the feature and adds ten spins, or twelve with the extra-spins modifier. Money collections use 2x at level two, 3x at level three and 10x at level four, and the new batch waits until the current one finishes before its multiplier applies. Starting at level two therefore changes the progression available from the outset. When fishermen appear without fish, dynamite can add fish or a bazooka can redraw the other symbols; with fish but no fisherman, a hook can pull a reel upward to bring one into view.
Direct bonus access is priced at 100x the spin stake, and its trigger can show anywhere from three to five scatters. The statistical sample used the USD 200 purchase with a USD 2 spin stake. Captured help lists USD 0.10–250 as the stake range, 96.71% theoretical RTP for both access routes, and medium volatility. A 5,000x total award stops the round even if free spins remain; the largest statistical result here was well below that limit.

Verdict
Retriggered features paid the second runRetriggers separated the two runs of Big Bass Splash: 16 of 84 natural features extended their spins in the first, 28 of 86 in the second, and the feature average moved from 59.90x to 73.40x, with 22 rounds above 100x in the second run against 14 in the first. The pooled 20,000 rounds returned 90.18% from 83.14% and 97.21% in the two sessions, so the printed 96.71% sits inside the approximate 95% band of 77.04 to 103.31% while the combined balance closed 1,965 stakes down. Between features the reels did not change: a hit on 14.08% and 13.3% of spins at a 1.0x median, 8,592 and 8,670 blank rounds, and empty runs of 51 and 56 spins at the longest.
Bonus rounds paid 62.9% of everything the 20,000 ordinary rounds returned: 170 features at one per 118 spins, 8.5 bHz, the lab's count of natural features per thousand rounds, 66.73x on average and 38.95x at the median, none of them empty and the smallest 2x. Two of them ran forty spins, round 9546 of run one for 269.6x and round 4497 of run two for 522.6x, the largest round on the page; without round 4497 the other 19,999 rounds returned 87.57%. The waits stretched past 600 spins three times, 955 spins from round 8490 to 9446 of run two at the longest, and the deepest fall, 3,116.3 stakes from a peak, belongs to run one at spin 9284.
One hundred USD 200 tickets came back at 0.640x of price, 64.04%: 0.356x at the median, USD 71.20, 78 tickets below their price, 22 above it and one, purchase 49 of run one, at USD 1,100, the only ticket past 5x. Bought rounds retriggered 22 times in 100 and ran 13.5 spins on average against 13.8 for the natural rounds, so the ticket opens the same feature the reels give, at 100 stakes a time. The fisherman feature arrives here once per 118 spins on average, and a 200-stake bankroll ran out by spin 5054 in one run and spin 399 in the other; the purchase route lost money on four tickets in five in both runs.
- Bonus rounds paid 62.9% of the pooled return, with 35 of 170 natural features above 100x
- Retriggers came in 44 of 170 natural features; the two forty-spin rounds paid 269.6x and 522.6x
- No natural feature in 170 paid nothing, and the smallest returned 2x the stake
- The base-game rhythm held across the runs: a hit every 7.1 and 7.5 spins at a 1.0x median
- Four bought tickets in five lost money in both runs, and only purchase 49 of run one reached 5x
- Empty runs of at least twenty spins occurred 134 times in 20,000 rounds, the longest 56
- Only one scatter-free spin in 20,000 passed 100x, the 200.5x hit on round 5798 of run two
- The wait for a feature passed 600 spins three times, 955 spins at the longest
Run 01·2026-09-10·83.14%
Most of the purchased-bonus payout came from collections: USD 5,456, against USD 469.60 from ordinary line combinations. A screen full of fish still needed a fisherman to turn its cash labels into a collection.
Purchases 11 and 25 each received four modifiers. Number 11 paid USD 562.80 over 24 spins; number 25 paid USD 29.20 over its twelve starting spins. No feature in either statistical series received all five modifiers. The opening icons described the conditions for those rounds, but gave a poor guide to their eventual payouts.
Purchase 49 was the clear outlier at USD 1,100. It began at level two with the extra-fishermen modifier, then extended from ten spins to thirty. Its fish collections paid USD 1,086 and line wins added USD 14. This was the only purchase to return at least five times its price; forty-one of the 50 buys paid less than their cost, and the median return of USD 57.90 was under one third of the USD 200 entry.
Ordinary play first built a surplus: the balance reached USD 101,746 on round 2590, whose natural feature paid USD 697.20, then fell to USD 95,513.40 by round 9284, a drop of 3,116.3 stakes from that peak. The final balance recovered to USD 96,628, leaving the loss at USD 3,372 and the return at 83.14% of USD 20,000 spent. The recorded extra-fish bonus paid USD 84 on a USD 200 purchase; the USD 1,100 best statistical purchase sits inside a series that lost USD 4,074.40. Both entry routes finished behind, and the fish did the paying in both.
Run 02·2026-09-29·97.21%
Round 4497 ran forty free spins, the longest feature of the run, and finished at USD 1,045.20, 522.6 stakes, the largest round on this page; 27 other natural features also extended past their starting award, and the 86 natural rounds averaged 14.5 spins against entries of ten, twelve, fifteen or seventeen. Their whole rounds came to USD 12,624.20, 64.9% of everything the 10,000 ordinary rounds returned, 73.40x per feature and 43x at the median: 21 features cleared 100x, 15 stayed under 20x, the smallest paid 10.4x, and the wait between triggers averaged 116 spins with one stretch of 955 spins, rounds 8490 to 9446.
Outside the feature one hit was worth writing down: round 5798 paid USD 401 on a single spin, 200.5 stakes, the only scatter-free round above 76x. Elsewhere 8,670 rounds paid nothing, the longest empty run lasted 56 spins from round 7803, and 75 runs of twenty or more empty spins were logged. The balance crossed its starting line on spin 486, climbed to 1,074.5 stakes up by spin 4540, then gave most of it back and closed 279 stakes down at USD 99,442, 97.21% of the USD 20,000 staked. The 200-stake test bankroll lasted 399 spins, the 100-stake one 119 and the 50-stake one 65.
On the purchase side, fifty USD 200 tickets produced USD 6,882.80 in return, 0.688x of price, 68.83%, on a 0.38x median, USD 76.00: 37 tickets below their price, 13 above it, three past 2x and none past 5x. Purchase 33 was the best at USD 544, 2.72x, over twenty spins; purchases 1 and 22 were the worst at USD 4 each. Thirteen bought features retriggered, the average bought round ran 14.1 spins and the longest 30 on purchases 10, 15 and 38, and fish collections supplied USD 6,618 of the USD 6,882.80, USD 132.36 per ticket, with line combinations adding USD 264.80.
