Fishermen are the only source of added spins: each fourth one banked adds 10 spins, or 12 with +2 SPINS, and those spins collect a stage higher; Scatters only set the opening award and never landed on a free spin screen in the test. With START FROM LEVEL 2 the count starts at four. In the test 20 of 100 natural rounds and 8 of 50 purchases got at least one such extension, 22 and 11 extensions in all.

Mission screen, a single +2 FREE SPINS upgrade and 12 free spins from a USD 200 buy at USD 2.00; on spin 12 a bazooka sets up a USD 32.00 collect and the fourth fisherman adds 12 spins at x2, where a USD 88.00 collect takes the total to USD 146.80 · Recorded in a separate browser session, outside the statistical samples.

One ticket equals 100 ordinary stakes. Natural bonuses occurred once per 100 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

9 rules screens from the game

Ten paylines run across a 5x3 grid, and every line win counts from reel 1 onward. The speedboat tops the table: five of them pay 200x the bet, and it is the one symbol that pays for a pair, 0.5x. Five dragonflies return 100x, the grappling gun and the tackle box 50x each, the fish 20x, A or K 10x, and Q, J or 10 5x. Scatters can stop on all five reels, while the diver-fisherman Wild appears in free spins alone and replaces any symbol except Scatters and fish.

Fish double as money symbols: the rules list eleven values from 2x to 5000x the bet, the top four being 100x, 200x, 500x and 5000x, and that money is paid only when a fisherman lands on the same free spin screen. Three, four or five Scatters start the bonus, and when just two land in the base game a random respin or a hook can bring in the third. The game then asks for a mission: FREE SPINS, worth 10, 15 or 20 spins by the Scatter count, or STACK THE CASH.

FREE SPINS begins with SELECT UPGRADES, six TOP SECRET folders opened one by one until a boot turns up. Behind them sit MORE FISH, MORE FISHERMAN, MORE DYNAMITES, HOOKS AND BAZOOKAS, START FROM LEVEL 2 and +2 SPINS, which adds two spins to the opening award and to every retrigger. Inside the round a fisherman gathers the values of all fish in view; each fourth one banked adds ten spins, played after those already awarded, and those added spins collect at the next stage, 2x, then 3x and finally 10x, after which the feature cannot extend again, while START FROM LEVEL 2 opens the round at the 2x stage. A free spin that ends with a fisherman and no fish can get dynamite fish or a bazooka that changes the other symbols, and one with fish but no fisherman can get a hook that pulls one in.

STACK THE CASH swaps the symbols for FISH COINS worth 1x to 10x or 25x the bet and blanks, with a robo-crab under each reel. The round starts with four respins, every new coin sticks and resets them to four, a full reel is banked on its crab and cleared, and each spin with a new coin drops a bomb that doubles the coins and crab of one random reel. Once no respins remain, the crabs' totals are added and paid; the test took FREE SPINS in all 100 natural and 50 bought bonuses, so none of its numbers describe this mode.

A purchase through BUY FEATURE costs 100 times the base bet, USD 200 here on the USD 2.00 base bet, and lets the player pick either mission, while the Ante switch moves the bet multiplier from 10 to 15 for extra Scatters and turns that purchase off. Regular play, Ante and the buy share a 96.50% RTP, the rules call the game medium volatility, the rules set the bet between USD 0.10 and USD 375.00, and a round hitting the 5,000x cap stops at once and forfeits any spins left.

Verdict

Level 2 from the first spin

Twenty-six of the 100 natural bonuses opened with START FROM LEVEL 2 and averaged 91.892x the bet per whole round, against 51.331x for the other 74; the medians were 65.6x and 33.85x. Round 1434 had that upgrade and no other, landed just two fishermen in ten spins and still paid 191.0x, because both of its collects, USD 240 and USD 120, came at 2x. Four of the five largest natural rounds started at level 2; the exception, round 336, got to the 10x stage without it at the twelfth of its 13 fishermen, over 48 spins.

Collects at 2x inside those 26 rounds made USD 4,176, 36.04% of the USD 11,586 that fishermen gathered in natural bonuses. Without the upgrade a round needs four landed fishermen to leave 1x, and 58 of the 74 never did; with it, 22 of 26 stayed at 2x and four went on to 3x.

Among the 50 USD 200 tickets, 21 hit the boot before any upgrade, while the seven that drew START FROM LEVEL 2 brought 46.15% of the USD 7,764.20 the purchases returned. Most of it came from ticket 27, which reached the 10x stage after eight landed fishermen, collected USD 2,240 at 10x on five spins and finished at USD 2,678, 13.39 times its price.

Measured upsides
  • One natural bonus per 100 ordinary rounds, 100 of them in 10,000 spins
  • Round 5259, the 364.2x top round, took USD 416 at 2x from two fishermen on its third free spin
  • No natural bonus paid under 10.0x the bet; rounds 2940 and 2941, back to back, were lowest at USD 20.00
  • Five collects at 10x brought ticket 27 USD 2,240
Measured downsides
  • The 22 natural bonuses that opened no upgrade had a 27.85x median
  • A single fisherman was all that nine natural bonuses landed
  • Ticket 37 drew no fisherman in its 10 free spins and returned USD 14.00 from line wins alone
  • Exactly three Scatters opened all 100 natural bonuses, so none began with 15 or 20 spins

FAQ

8 questions · answered from the log
Which upgrade behind the TOP SECRET folders pays off most in Big Bass Mission Fishin'?
Lab answer

START FROM LEVEL 2. In the first test run, natural bonuses that drew it had a 65.6x median as whole rounds, against 33.85x for those without it, and they brought 38.61% of all natural bonus money. It opens the free spins at the 2x collect stage, while +2 SPINS, the most frequent upgrade with 34 natural rounds, had a 38.1x median with it and 44.0x without.

Without buying, after how many spins do Big Bass Mission Fishin' free spins usually trigger?
Lab answer

Roughly 100: the 10,000 test rounds at USD 2.00 produced 100 natural triggers. Each began with 10 free spins, or 12 when +2 SPINS was among the upgrades, and 20 of the 100 were extended by a fourth fisherman.

Big Bass Mission Fishin' bonus buy: how much of the 100x price came back?
Lab answer

77.642%. Fifty tickets of USD 200, bought with the bet at USD 2.00, returned USD 7,764.20 of USD 10,000; the median one paid USD 63.60, 0.318x its price. Counted in bets, a bought round averaged 77.642x against 61.877x for a natural one, trigger spin included in both, so the purchase fell well short of its 100x price.

What is STACK THE CASH in Big Bass Mission Fishin', and was it part of the test?
Lab answer

The second mission, offered after every trigger or purchase: coin symbols worth 1x to 10x or 25x the bet stick on the reels, four respins reset with each new coin, robo-crabs bank full reels and bombs double them. The test did not play it; all 100 natural and 50 bought bonuses were taken as FREE SPINS, so every bonus figure on the page comes from that mission.

Against its 96.50% RTP, where did Big Bass Mission Fishin' land in 10,000 demo spins?
Lab answer

94.66%, from USD 18,931 paid back on USD 20,000 of USD 2.00 spins. Its approximate 95% CI, 77.52% to 111.79%, contains the listed figure, and natural bonus rounds, trigger spins included, supplied 65.37% of everything the series paid.

Counting fishermen, when does Big Bass Mission Fishin' reach the 10x collect?
Lab answer

At the twelfth fisherman of a round: the fourth, eighth and twelfth each add ten free spins, 12 with +2 SPINS, and those added spins collect a stage higher, at 2x, 3x and then 10x. START FROM LEVEL 2 opens the round at 2x, which is how ticket 27 reached 10x after eight landed fishermen; among the 100 natural bonuses only round 336 got there, and its one 10x collect paid USD 140.

Can the bazooka in Big Bass Mission Fishin' rescue a free spin with no fish?
Lab answer

Yes. A bazooka, by the rules, may change every symbol except the fisherman at the end of a free spin that has a fisherman but no fish, dynamite can drop fish in the same situation, and the MORE DYNAMITES, HOOKS AND BAZOOKAS upgrade raises the chance of such features. In the filmed bought round, a bazooka on the 12th free spin left fish beside the fisherman and the collect paid USD 32.00.

Will the Ante bet change the RTP of Big Bass Mission Fishin'?
Lab answer

No. Regular play, the Ante and the buy all carry 96.50% in the rules; the Ante lifts the bet multiplier to 15 from 10, so a USD 2.00 base bet costs USD 3.00, adds Scatters to the reels and switches BUY FEATURE off. All 10,000 test rounds were played without it.
