A retrigger here is the fourth, eighth or twelfth fisherman banked in one round, each worth ten added spins at a 2x, 3x and finally 10x collect rate; the 10, 15 or 20 spins set by the Scatters at the start are not part of it. Natural bonuses were extended 40 times across 36 of 98 rounds, bought ones 21 times across 12 of 50.

How it plays
7 rules screens from the game
Big Bass Halloween lays out ten paylines across a 5x3 grid and counts wins from the leftmost reel. The lifebuoy pays most, 200x the bet for a line of five, and it alone pays two of a kind, 0.5x; five gaff hooks pay 100x, five crows or tackle boxes 50x, five fish 20x and five of any card from A to 10 pay 10x. The bass Scatter can land on every reel, and the fisherman Wild shows up during free spins alone, standing in for every symbol but the Scatter.
Each fish is also a MONEY symbol showing one of seven random values from 2x to 50x the bet, or 2000x. Those values are won only in free spins, when a fisherman on the same screen collects all of them. Ten free spins follow three Scatters, 15 follow four and 20 follow five. With a lone Wild on the screen as a free spin finishes, the game may drop extra fish into random spots.
Every fisherman is banked until the bonus ends, and each fourth one adds ten free spins and raises the collect multiplier, first 2x, next 3x and finally 10x; after that third retrigger the round cannot be extended again. The new rate applies only to the added spins, which are played once the current batch runs out. A round that reaches 2,100x the bet stops there and pays the cap, forfeiting whatever free spins remain.
Regular play, the Ante and the purchase all carry a 96.06% RTP. The panel on the left sells the free spins for 100x the bet (USD 200 on this test's USD 2.00 bet), and its Ante switch takes the bet multiplier from 10x to 15x for more Scatters on the reels, with no purchase possible while it is on. Stakes span USD 0.10 to USD 375.00, and Reel Kingdom rates the game low volatility.

Verdict
Cheaper fish on bought screens
Over 765 bought free spins, 2,195 fish landed, 2.87 per spin, and 71.0% of them were 2x or 5x fish; the 1,390 natural free spins showed 3,931, 2.83 per spin, with the 2x and 5x kind at 49.3%. Fishermen came at a similar rate, 3.68 per ticket and 3.59 per natural bonus, so the gap arrived in what they gathered: the median spin that collected at 1x paid USD 14.00 after a purchase and USD 30.00 in a natural bonus. Among rounds that stopped after ten free spins, the 35 tickets had a USD 38.00 median and the 61 natural bonuses USD 62.00.
Natural bonuses never got past x3: 62 of the 98 ended without a retrigger, four were extended twice to the x3 stage, and an x3 Wild collected on just two spins of the series, USD 24 between them. They still came once per 102.04 rounds and, trigger spins included, produced 59.68% of what the 10,000 ordinary spins paid out. The best of them, round 6491, ran 30 spins and took USD 360 in one collect at x2 on spin 14, most of its USD 544.
Only tickets reached the x10 collect stage, which takes twelve fishermen in one round: four of the 50 got there, and six spins that collected at x10 paid USD 2,460, 33.1% of the fish money gathered on bought rounds. Ticket 44 banked 17 fishermen in 45 spins and collected USD 640 and USD 440 at x10 on spins 40 and 41, finishing at USD 1,722, 8.61 times its price; ticket 10 took USD 840 at x10 on its last free spin from fish worth 42x the bet. Those four x10 tickets hold 59.2% of the free spins money of all 50 purchases.
- Three x10 collects on ticket 44, on spins 40, 41 and 44, paid USD 1,220 of its USD 1,722
- Round 6491's x2 collect on spin 14 took USD 360, 180x the bet
- Natural free spins arrived once per 102.04 rounds of the series
- Natural bonuses paid USD 115.87 on average, 57.93 times the USD 2.00 bet
- Tickets that ended after ten free spins paid USD 38.00 at the median
- Round 8989's natural bonus returned USD 31.00 from ten free spins, the lowest of the 98
- Nine free-spin screens held a 2000x fish, and no fisherman landed beside any of them
- The weakest ticket, number 18, paid USD 4 for its USD 200

FAQ
5 questions · answered from the log
Were the fish worth less in the bought Big Bass Halloween free spins?
Yes. Of 2,195 fish on 765 purchased free spins, 29.0% carried 10x the bet or more, and the average fish, 2000x ones aside, was worth 6.79x the bet; natural free spins showed 50.7% of 3,931 fish and 10.20x. The rules give a single list of fish values, 2x to 50x plus 2000x, without separating the two ways into the bonus.
Which fisherman switches on the 10x collect in Big Bass Halloween free spins?
The twelfth of the round. Every fourth fisherman adds ten free spins and lifts the rate for those spins, to 2x at the fourth, 3x at the eighth and 10x at the twelfth, and that third retrigger is the last. Four of the 50 bought rounds got there in the test and no natural one did; round 3675 stopped one short with 11 fishermen.
If I buy the Big Bass Halloween bonus 50 times at USD 200, what comes back?
In the test, USD 7,688 of USD 10,000, or 76.88%. The median ticket paid USD 43.50, and leaving out ticket 44 with its USD 1,722, the other 49 returned USD 5,966 of the USD 9,800 they cost.
Which RTP did the Big Bass Halloween demo deliver over 10,000 spins?
95.14%, as USD 19,027 was paid back on USD 20,000 staked at USD 2.00, while the game declares 96.06% for regular play, Ante and purchase alike. Its approximate 95% CI stretches from 80.37% to 109.9%.
Without the bonus buy, what is the usual wait for Big Bass Halloween free spins?
One natural trigger per 102.04 rounds on average, 98 over the 10,000-spin series. Ninety-six were three-Scatter starts with 10 free spins, two had four Scatters for 15, and five Scatters never landed on a trigger.
