The Big Bass Secrets of the Golden Lake slot is a 2024 Reel Kingdom game, distributed by Pragmatic Play, with 10 fixed paylines. Its twist on the Big Bass formula is a card pick that sends you to either classic free spins or Golden Lake free spins, where only fish and fishermen land. RTP starts at 96.07% and the max win is 5,000× stake.
Three RTP versions exist: 96.07%, 95.07% and 94.07%, so check the help screen.
Scatters lead to a 12-card pick that chooses between the classic round and the Golden Lake round.
Every fourth Fisherman wild collected adds 10 spins and raises the money multiplier, up to 10×.
Top prize: 5,000× stake, or £10,000 on a £2 spin and £25,000 on a £5 spin.

Big Bass Secrets of the Golden Lake slot: the quick answer
This is a fishing slot from Reel Kingdom, the studio behind the Big Bass series, released through Pragmatic Play in 2024. It keeps the series’ core idea, where a Fisherman wild collects the cash values on fish symbols, and adds a medieval, mythological setting with an enchanted lake. The new element is a choice of bonus rounds decided by a card pick.
If you already know Big Bass Bonanza, you will recognise the base game instantly. The differences are in the bonus, in the higher 5,000× ceiling, and in the RTP, which tops out at 96.07% rather than the 96.71% of the original.
Golden Lake shares Big Bass Splash’s 5,000× ceiling but at a lower top RTP. That difference, 96.07% against 96.71%, is worth about 64p per £100 staked on average. Our comparison of Big Bass Bonanza and Big Bass Splash shows how small rule changes move the maths across the series.
Reels, lines and fish money symbols
The grid is five reels by three rows with 10 fixed paylines. Wins need three or more matching symbols on a line from the leftmost reel; the top symbol pays from two. At a £1 total stake, each line carries 10p, and the paytable shows prizes in pounds for your stake.
Money fish symbols pay as normal line symbols, but each also carries a cash value shown as a multiple of the stake. In the base game those values can be collected at random. In the free spins, the Fisherman wild collects every value in view whenever he lands, which is the heart of the Big Bass design and a variation on Cash Collect.
How the Big Bass Secrets of the Golden Lake slot machine reaches the bonus
Set a stake within UK limits: up to £5 per spin at 25 and over, £2 at 18–24.
The RNG fixes the result; the reels take at least 2.5 seconds to settle.
Line wins are paid. Money fish values may be collected at random in the base game.
Three or more Hooked Bass scatters trigger the bonus, with more scatters meaning more starting spins, up to 20.
Twelve face-down cards appear and you pick one.
A Bonus card starts the classic free spins; a Golden Lake card starts the Golden Lake free spins.
Landing two scatters can sometimes set off a random feature that moves or adds scatters, giving a second chance at the trigger. Like every random feature, it is part of the RTP and not a sign that the bonus is building. Our explainer on scatter symbols covers how scatters differ from line symbols.
The card pick: classic or Golden Lake?
The 12-card pick is presented as a choice, but it works like a lottery draw: the cards are face down, so there is nothing to choose between until they are turned. Published descriptions say two of the cards lead to the Golden Lake round, which means the classic round is the more common outcome. The game’s maths accounts for both, so the pick does not change the long-run return; it changes which kind of bonus you play this time.
Our page on pick-me bonuses explains why face-down picks are not a skill element.
Classic free spins and the fisherman ladder
The classic round plays like the familiar Big Bass bonus. Money fish land with cash values, and each Fisherman wild that lands collects every value on screen. Fishermen are also counted on a meter. Every fourth one collected adds 10 more spins and raises the multiplier applied to fish values, up to 10× after 12 fishermen.

From the maximum start of 20 spins, a full ladder adds 30 more, for 50 in total. That is the free spins retrigger structure the series is known for. The exact multiplier at each step is in the help screen.
Golden Lake free spins: a reel set of fish and fishermen
The Golden Lake round starts with 10 spins on a special reel set where only money fish, Fisherman wilds and blanks can land. With no regular symbols to take up space, every spin is about collection, and the same fisherman meter and multiplier ladder apply. Random extras can add a money fish when a fisherman lands alone, or hook a fisherman onto the reels when fish land without one.
An illustrative example at a 20p stake, with values invented for the arithmetic: three fish showing 2×, 5× and 10× add up to 17× the stake, which is £3.40. If a fisherman lands at the second level of the meter where the multiplier has risen to 2×, the same collection pays £6.80. The point is that the multiplier applies to the whole collection, which is why later spins in a long round can pay much more than earlier ones.
Golden Lake is the rarer and more variable of the two rounds. It can pay more, but it can also finish with only a few small collections.
Big Bass Secrets of the Golden Lake RTP across three versions
Pragmatic Play supplies the game at 96.07%, 95.07% and 94.07%. The casino chooses, and the difference is noticeable over time. This table shows the long-run average cost of 100 spins.
Big Bass Secrets of the Golden Lake max win in pounds
In pounds, 5,000× means £500 from a 10p spin, £1,000 from 20p, £5,000 from £1, £10,000 from the £2 spin open to 18–24s and £25,000 from £5. It is a ceiling written into the game, and reaching it is very rare. A max win cap also means a bonus ends once the limit is reached.
UK rules that shape the Golden Lake version
Some international versions offer a bonus buy for each round. Those buy options are absent from the version supplied to Great Britain, so UK players reach both rounds only through the scatters and the card pick. If your version lists an ante bet, its cost and RTP are stated in the help screen, and the total per spin counts towards the stake limit.
The 2021 design rules, in force from 31 October that year, remove autoplay, turbo and slam-stop, set a 2.5-second minimum spin and stop games celebrating returns at or below the stake. Stake limits of £5 (25+, from 9 April 2025) and £2 (18–24, from 21 May 2025) apply. Our page on the £2 limit for 18 to 24s explains how age bands are checked.
Fishing myths on Big Bass slots
Fish on screen without a fisherman means one is due. Each spin is independent, so a missed collection has no influence on the next. Picking a different card position changes your chances. The cards are face down and the result is set by the game’s maths. Golden Lake always pays more. It can, but it can also pay very little. The base game is just filler. Line wins and random collections are part of the RTP, even if the bonus is where the larger results come from. For more, see slot machine myths.

Frequently asked questions
What is the Big Bass Secrets of the Golden Lake RTP?
The highest version has an RTP of 96.07%, and Pragmatic Play also supplies 95.07% and 94.07% versions. At 96.07%, the long-run average cost is about £3.93 per £100 staked; at 94.07% it is about £5.93. Casinos choose the version, so check the help screen or paytable before playing. Short sessions vary widely from these averages. Why studios supply more than one setting is explained under RTP variants.
What is the max win on Big Bass Secrets of the Golden Lake?
The game stops paying at 5,000× your stake, which comes to £500 on 10p, £5,000 on £1, £10,000 on the £2 maximum for under-25s and £25,000 on the £5 maximum for everyone else. It matches Big Bass Splash and is above the original Big Bass Bonanza’s 2,100×. Reaching it is very rare, and once the cap is hit the round ends. See max win caps for how caps work.
How do you trigger free spins on Big Bass Secrets of the Golden Lake?
Land three or more Hooked Bass scatters in one spin. More scatters give more starting spins, up to 20. You then pick one of 12 face-down cards: a Bonus card starts the classic free spins and a Golden Lake card starts the Golden Lake free spins. Two scatters can sometimes trigger a random feature that adds or moves scatters. There is no bonus buy in the UK. Read how free spins work on slot machines for background.
What is the difference between classic and Golden Lake free spins?
The classic round uses the normal reels, where money fish, regular symbols and Fisherman wilds can all land. The Golden Lake round starts with 10 spins on a special reel set of only money fish, fishermen and blanks, so every spin focuses on collections. Both use the same fisherman meter, with extra spins and a rising multiplier. Golden Lake is rarer and more variable. Our fishing slot machines page compares collect designs across the genre.
How does the Fisherman wild work?
The Fisherman is a wild that, in the free spins, collects the cash value of every money fish in view when he lands. Each fisherman is also counted on a meter: every fourth one adds 10 extra spins and raises the multiplier applied to fish values, up to 10× after 12. A fisherman landing with no fish collects nothing, though random extras can add fish. Our Big Bass Bonanza page explains how the mechanic started.
Does the card I pick matter?
No, not in any way you can influence. The 12 cards are face down, and the outcome is set by the game’s maths; published descriptions say two cards lead to Golden Lake, so the classic round is the more common result. Picking a corner or the middle makes no difference. The pick decides which round you play this time, not the long-run return. Our pick bonus glossary entry explains how these features are built.
Is Big Bass Secrets of the Golden Lake better than Big Bass Bonanza?
It is different rather than better. Big Bass Bonanza has a higher published RTP of 96.71% and a 2,100× max win, while Golden Lake has a 96.07% top RTP, lower versions, a 5,000× max win and a second bonus type. If cost per spin matters most, the original is cheaper on average. If you want a choice of bonus rounds and a higher ceiling, Golden Lake offers that. See our Big Bass Bonanza vs Bigger Bass Bonanza comparison for how the series has evolved.
Can I play the Big Bass Secrets of the Golden Lake demo?
Yes. You will find it as free demo play, after age verification, at many casinos that stock Pragmatic Play games; the age check has applied to UK demos since May 2019. The demo follows the same rules as the real game, so it shows how often each bonus round comes up and how the fisherman meter works. It does not show which RTP version a casino uses for real money. Our demo slots guide explains what demos can and cannot tell you.
Can I use PlayOJO’s free spins on Big Bass Secrets of the Golden Lake?
No. PlayOJO’s welcome spins are played on the original Big Bass Bonanza, not on this game. The offer is for new UK customers aged 18 and over, excluding Northern Ireland, and gives 80 free spins at 10p each with a first deposit of £10 or more. There is no wagering, so winnings are paid in cash. It can’t be combined with other offers. Terms apply. Our PlayOJO free spins page covers the details.
Who makes Big Bass Secrets of the Golden Lake?
The game was made by Reel Kingdom, the studio behind the Big Bass series, and distributed by Pragmatic Play, which released it in 2024. Reel Kingdom’s breakthrough game was Big Bass Bonanza in December 2020, and its signature mechanic is the Fisherman wild that collects fish cash values. Pragmatic Play handles distribution to casinos. Our Reel Kingdom page lists the studio’s other titles.
