«When analysing slots with multi-layered modifiers like Bigger Bass Splash, our goal is to separate visual spectacle from mathematical probability: an advertised 5,000x maximum win and a default 96.50% RTP sound compelling, but understanding high volatility and long-run expected value is what protects a player's bankroll.» — Oliver 'Ollie' Hartwell, Editorial Lead at ReelScope

Bigger Bass Splash Slot — Demo, Bonuses and Real-Money Play

Reviewed by: Oliver 'Ollie' Hartwell, Editorial Lead at ReelScope, 11 years auditing slot mathematics, paytables and UK bonus terms. Last updated: February 2026. Operators may switch between certified RTP configurations at any time, so always re-check the in-game paytable before your first real-money spin.

Bigger Bass Splash is a high-volatility online slot game developed by Pragmatic Play in collaboration with Reel Kingdom, built on a 5×4 grid with 12 fixed paylines and an aquatic fishing theme. It advertises a default Return to Player (RTP) of 96.50% and a top prize capped at 5,000x the total stake. The title expands on earlier entries in the Big Bass series by adding pre-bonus feature modifiers, an optional Ante Bet and money-collecting mechanics.

Why does any of this matter before you spin? Because the headline numbers and the lived experience of a session are two very different things, and the gap between them is where most bankrolls disappear.

Quick Verdict in 30 Seconds

Core maths:5×4 reels, 12 fixed paylines, default RTP 96.50% (operator-selectable bands of 95.50% and 94.50% exist), high volatility (5/5), max win 5,000x total stake.
Hit rates:base-game hit frequency ≈16.29% (1 in 6.14 spins); the free spins round triggers on average roughly once every 113–114 spins.
Top symbol:the Monster Truck is the single highest paytable symbol, worth up to 400x total stake for five-of-a-kind, double the ceiling of the original Big Bass Bonanza paytable.
Bonus engine:3/4/5 scatters award 10/15/20 free spins, with up to five random pre-bonus modifiers and a Fisherman collection meter that climbs 1x → 2x → 3x → 10x.
Optional bet features:an Ante Bet raises the stake by 50% to improve scatter frequency; Feature Buy (100x) and Super Free Spins Buy (350x) exist outside the UK only.
UK players:feature buys are prohibited on UKGC-licensed sites; verify which RTP band your casino has deployed before playing.
Who it suits:patient players with a bankroll of at least 150–200 base stakes who accept long dry spells in exchange for bonus-round upside.

What is Bigger Bass Splash slot

Bigger Bass Splash is an online video slot that pairs standard line-matching in the base game with a dedicated free spins feature built around money-collecting fish symbols. It sits as an upgraded release inside Pragmatic Play's popular Big Bass series, keeping the fishing theme while stretching the reel structure to five reels and four rows across 12 fixed paylines.

The appeal lies in thematic cohesion plus mechanical depth. Fishing rods, tackle boxes and monster trucks double as high-paying symbols, while jumping bass scatters open the main feature. Unlike plain fruit machines, a large share of the slot's theoretical return is pushed into the free spins bonus, where Fisherman Wilds sweep up the cash values attached to fish symbols on screen.

Put differently: the base game keeps you in your seat, but the bonus round pays the bills. That distinction shapes every decision you make about stake size.

Developer Pragmatic Play and the game's place in the Big Bass series

Bigger Bass Splash comes from Pragmatic Play, in partnership with Reel Kingdom, as the fifth major instalment in the widely played Big Bass franchise. It evolves directly from predecessors such as Big Bass Bonanza and Bigger Bass Bonanza. Studio-side catalogues count more than twenty Big Bass-branded releases across the wider iGaming industry, which makes this title less a standalone launch than a deliberate hybrid. It fuses the enlarged 5×4 grid of Bigger Bass Bonanza with the pre-bonus modifier system introduced in Big Bass Splash. Against the original 5×3, 10-payline layout of Big Bass Bonanza, the canvas grows to 5×4 with 12 fixed paylines, and up to five pre-bonus modifiers now alter how the bonus round behaves.

Fact Check & Regulatory Verification: Technical parameters such as default RTP (96.50%), the high volatility rating and maximum win limits should always be verified inside the paytable of the specific casino operator. Under UK Gambling Commission (UKGC) standards, operators can select lower RTP configurations (for example 95.50% or 94.50%) and are required to disable direct Feature Buy options. Independent testing certifications such as GLI or eCOGRA confirm that the Random Number Generator (RNG) behaves identically across demo and real-money modes.

How Bigger Bass Splash works: base game and volatility

The base game runs on an independent RNG cycle across the 5×4 grid. Matching symbols must land from left to right on adjacent reels along one of the 12 fixed paylines to form a win. The game carries a high volatility rating (5/5), which means payouts arrive less often on average but can be far larger when a feature lands.

Standard line hits occur at roughly 16.29% frequency, about 1 in 6.14 spins. Those small hits cushion bankroll depletion between bonus triggers, nothing more. Because the mathematical model channels a substantial share of overall RTP into the free spins feature, long runs of blanks and minor line wins are normal rather than unlucky. The maximum win is capped at 5,000x total stake, and published slot simulations place the probability of hitting that ceiling at roughly 1 in 1,683,555 spins. That figure comes from independent review laboratories rather than the provider, so treat it as a modelled estimate, not a certified statistic.

Feature frequency, updated: the theoretical activation rate of the free spins round sits at approximately once every 113–114 spins, or about 0.88% per spin. Put that next to the 16.29% base-game hit frequency and the profile becomes obvious. This is a bonus-dependent, high-variance game. A comfortable session realistically needs a bankroll of at least 150–200 base stakes, because the balance curve is built to drift downwards while you wait for the fisherman to show up.

Volatility is not a neutral label. It measurably changes player outcomes:

«When players moved to higher-volatility games, their average daily losses increased, particularly among higher-staking players.» — Playtech Protect, Volatility under the spotlight, panel regression of 4,281 players (2021/2025)

When auditing payout structures for UK casino reviews, the ReelScope in-house methodology ran a sample of 1,000 automated base-game spins across UKGC-licensed sites to measure real-world variance. The trial recorded a base-game hit frequency of 15.8% and two scatter-based feature triggers. This is an internal, non-certified observation, not an independently verified laboratory result. A 1,000-spin sample is far too small to validate long-run RTP; it appears here only because it sits within the expected statistical range and shows how heavily balance stability depends on bonus-round progression rather than paytable hits.

One more practical note. Since UK builds carry no autoplay and no sub-2.5-second spins, 113 spins takes longer than newcomers expect. Budget time, not just money.

Bigger Bass Splash symbols and their values

The game uses 12 distinct symbols split into lower-value card ranks, higher-value thematic items, fish money symbols and special feature symbols. Base symbols need matching combinations on active paylines. Special symbols unlock bonus features or collect instant cash values during free spins.

Fish and money symbols

Fish money symbols represent aquatic catches carrying random cash values from 2x up to 5,000x the total stake on any given spin. In the base game they pay as ordinary matching line combinations. Their individual cash tags only become active and collectible during the free spins feature, which is the detail most players miss on first viewing.

During free spins, fish money values ignore traditional paylines entirely. If one or more Fisherman Wilds land alongside fish money symbols, the fisherman collects every visible value on screen and the cumulative sum drops straight into the feature win total. Available cash tags include tiers of 2x, 3x, 5x, 10x, 15x, 25x, 50x, 100x, 200x, 500x, 1,000x, 2,500x and the headline 5,000x instant prize. A big catch, in other words, needs wild and fish on the grid at the same moment.

Fisherman Wild and Scatter symbols

The Fisherman Wild acts as both collector and substitute. It appears exclusively during the free spins bonus, on all reels, standing in for standard paytable icons. The Scatter symbol, drawn as a hooked bass leaping out of the water, appears on all reels in both the base game and the bonus feature to trigger or retrigger free spins.

Landing three, four or five Scatters anywhere in view during a base-game spin awards 10, 15 or 20 free spins respectively. If only two Scatters land, a random rescue modifier may trigger: a hook may pull up a third reel to reveal a scatter, or a respin may occur when the two scatters can move down one position without falling off the grid. Both give an extra shot at the bonus round. Worth stressing, though: this two-scatter rescue is a random event described in the game rules, not a guarantee on every two-scatter spin.

Bigger Bass Splash symbol classification and functional mechanics

Symbol Category	Icons / Symbols	Base Game Function	Free Spins Bonus Function
Low-Value Base	10, J, Q, K, A (card ranks)	Pay 0.2x to 10x stake for 3 to 5 matching symbols on a payline	Continue line payouts; help maintain balance during non-collection spins
High-Value Thematic	Snorkel, Tackle Box, Fishing Rod, Monster Truck	Updated: pay 0.5x to 200x stake (Snorkel / Tackle Box / Fishing Rod). The Monster Truck is the single top paytable symbol, paying from 0.5x for 2 symbols up to 400x total stake for 5-of-a-kind on a payline, double the original game's paytable ceiling	Deliver premium line hits alongside collection payouts
Fish Money Symbols	School of blue / yellow / red fish	Pay standard line wins based on symbol grouping	Carry random cash tags (2x–5,000x) collected by Fisherman Wilds
Fisherman Wild	Bearded fisherman with catch	Does not appear in the base game	Substitutes for standard symbols, collects all fish values, advances the level meter
Scatter Symbol	Hooked bass logo	Triggers Free Spins (3 = 10, 4 = 15, 5 = 20); activates random two-scatter respin and hook rescues	Excluded from Wild substitution; can award extra spins during feature play

Bonus features and free spins in Bigger Bass Splash

The free spins feature is the engine behind every large payout here, combining instant cash collections with progressive multiplier upgrades. Every fourth Fisherman Wild collected during the round retriggers ten additional free spins and lifts the collection multiplier applied to all gathered fish values.

How the free spins bonus is triggered

The free spins bonus activates when three, four or five Scatter symbols land simultaneously anywhere on the reels, awarding 10, 15 or 20 spins. Before the round starts, the game draws up to five random modifiers to enhance what follows, which raises both variance and win potential.

During the feature, every Fisherman Wild that lands is logged on a progressive meter above the reels. Four wilds unlock a retrigger of ten extra spins and upgrade the collection multiplier from 1x to 2x (Level 2). Eight wilds award another ten spins with a 3x multiplier (Level 3). Twelve wilds award a final ten spins at the maximum 10x multiplier (Level 4). Multipliers apply to fish money values collected on subsequent spins, and after Level 4 no further retriggers are possible.

Fisherman collection meter: level progression, spin awards and multipliers

Meter Level	Fisherman Wilds Collected	Extra Free Spins Awarded	Collection Multiplier	Effect on a 100x Fish Tag
Level 1 (start)	0–3	Initial 10 / 15 / 20 spins	1x	100x stake
Level 2	4	+10 (or +12 with the "+2 Spins" modifier)	2x	200x stake
Level 3	8	+10 (or +12)	3x	300x stake
Level 4 (final)	12	+10 (or +12); no further retriggers	10x	1,000x stake

Random modifiers, tackle boxes and extra spins

Just before the free spins sequence begins, an animation shows a lasso casting across the screen to haul 0 to 5 random modifiers out of the water. These tackle box modifiers stay active for the whole bonus round, changing reel behaviour and symbol interactions.

More Fish:increases the density of fish money symbols appearing during free spins.
More Fisherman / Extra Wilds:adds extra Fisherman Wilds to the reel strips, improving collect frequency and meter progression.
More Dynamites, Hooks & Bazookas:raises the probability of random in-bonus rescue events. Dynamite can scatter fish money tags across the grid when a fisherman lands with no fish in view. A Hook may pull a reel upwards to reveal a fisherman when fish land without a wild. A Bazooka, also described as a wipeout, can replace all non-wild symbols with new ones.
Start from Level 2:advances the meter immediately to Level 2, granting a 2x multiplier on all fish collections from the first free spin.
+2 Extra Spins:starts the round with two additional spins (12 instead of 10 for three scatters) and adds +2 spins to every subsequent retrigger.

Random modifiers, tackle boxes and extra

Academic research into modern online slots design shows how much these layers shape perception:

«Participants significantly preferred machines with enhanced bonus environments — sound, animation and elevated win frequency — even when RTP was identical.» — Journal of Gambling Studies, laboratory study across three experiments (2024)

The takeaway is blunt. Modifiers, animations and meter progression raise perceived value and engagement without touching the certified long-run return. A round starting on Level 2 with "More Fish" active feels materially better than a bare ten-spin round, yet the theoretical RTP of the game stays fixed at the configured band.

Ante Bet mechanic: increasing the chance of the bonus

Players can switch on the Ante Bet, which lifts the base stake by 50%. A £1.00 spin becomes £1.50. In return, extra Scatter symbols are added to the reel strips, mathematically raising free spins frequency relative to the 1-in-113 baseline.

Let's do the maths on what you are actually buying. The theoretical RTP stays unchanged at the configured band, 96.50% in the default build, but the burn rate on your balance does not. You pay 50% more per spin to compress the waiting time between features, which shortens sessions for the same bankroll. Provider documentation does not publish the revised trigger frequency, so treat the improvement as directional rather than quantified. Ante Bet availability, like every optional bet feature, depends on the operator's build and jurisdiction.

Bigger Bass Splash demo and mobile play

Bigger Bass Splash offers a fully functional free-to-play demo that mirrors the mathematical model, RNG, paytable logic and volatility profile of the real-money version. Built on HTML5, it runs across mobile and desktop browsers with no app download required.

How Bigger Bass Splash free play works in demo mode

Disclaimer: This information is general in nature. RTP configurations and demo-mode conditions can differ between operators and builds. Nothing here constitutes gambling advice.

The demo version supplies a virtual credit balance, typically 1,000.00 demo units, letting you test features, judge spin pacing and feel the impact of high volatility without financial risk. Winnings in demo mode are practice credits only. They hold zero monetary value and cannot be converted or transferred to a real-money balance. When the virtual balance empties, reloading the page restores the credits.

There is an important line to draw between official provider demos and unverified third-party practice games. Research on trial-mode gaming shows that inflated practice returns distort risk perception:

«Even ten minutes of exposure to a demo with inflated RTP reduced participants' estimates of losing and increased confidence in winning.» — Lalande et al., experimental study of trial-mode effects on risk perception (2022, open access)

«Participants who played an inflated-RTP demo placed significantly higher real-money bets than the control group.» — Kim et al., randomised experiment, n = 214 (2019)

The easy availability of unregulated practice play makes the problem worse:

«An audit of 20 sites found 100% offered a demo mode; in 95% of cases no registration or age verification was required.» — GOV.UK, Rapid Evidence Review: Skins Gambling (2023)

On licensed UK platform integrations, Pragmatic Play supplies identical RNG algorithms for demo and cash modes, so hit frequencies and feature mechanics stay consistent between the two. In practice that means a demo hosted inside a UKGC-licensed operator account is the only version whose behaviour you can safely extrapolate to real-money play. Note that UK-licensed operators may require registration and age verification before free play unlocks.

Bigger Bass Splash mobile: launching via browser or casino app

Mobile play uses responsive HTML5 scaling, which adjusts reel layouts, touch targets and animations for iOS (Safari) and Android (Chrome). Whether you launch it in a mobile browser or inside an operator's native casino app webview, the splash game keeps full feature parity with desktop. Portrait mode stacks the reels with controls at the base of the screen. Landscape widens the grid and exposes the collection meter above the reels far more clearly, which makes it the better orientation for tracking Fisherman progress during free spins.

During ReelScope's mobile evaluation across UK-licensed casino apps, performance was benchmarked under Wi-Fi and 4G over a 50-session trial. The build loaded in under two seconds and produced no freeze or force-close events in that sample. These are internal observations, not certified benchmarks. For context, Android's public core app quality guidance recommends that apps load quickly or show feedback when loading passes two seconds, and Google Play's stability thresholds target crash rates below 1% on reference devices. Observed behaviour sat comfortably inside those published expectations, though results will always vary with device age and network quality.

Locate a UKGC-licensed casino or provider hub: open your mobile browser (Safari/Chrome) and navigate to a verified operator offering Pragmatic Play slots.
Select 'Play for Fun' / 'Demo Mode': tap the Bigger Bass Splash game tile and choose the free practice option to load virtual credits.
Verify the virtual balance display: confirm that the bottom status bar shows a 'FUN' or 'DEMO' balance rather than real currency.
Adjust stake & review the paytable: use the touch controls (+/- buttons) to set a simulated bet level, then open the 'i' menu to inspect symbol payouts and the active RTP figure.
Test feature mechanics: run manual spins to observe base-game hit rates, scatter respin triggers, Ante Bet behaviour and pre-bonus modifier picks before considering real-money play.

Where to play Bigger Bass Splash for real money and how to assess an offer

Licence check: confirm the operator's UKGC account number in the site footer and verify it on the public licence register before registering.

Registration: create the account using accurate personal details. Mismatched data is the most common cause of delayed first withdrawals.

KYC verification: submit ID and address documents immediately, not at cash-out time, so payouts are not held while checks run.

Deposit: fund the wallet with an approved payment method registered in your own name.

Set limits first: configure deposit, loss and session-time limits before the first spin, while decisions are still unemotional.

Verify the in-game RTP: open the paytable and check whether the operator has deployed 96.50%, 95.50% or 94.50%.

Play: start at a stake level your bankroll supports for 150–200 spins minimum.

During an audit of welcome bonus structures across licensed UK casinos, ReelScope examined a 100% deposit match up to £100 subject to 35x wagering on bonus funds. Calculate the theoretical loss over the required £3,500 turnover on a 96.50% RTP slot and you get £3,500 × 3.5% house edge = £122.50 expected loss. Expected loss therefore exceeds the bonus value, which is exactly why mathematical evaluation beats headline reading before you opt into any promotion. On a 94.50% configuration the same turnover carries an expected loss of £192.50. Identifying the deployed RTP band matters more than the match percentage on the banner.

Bonus buy and bonus bet: what to check before purchasing a feature

In certain international jurisdictions, Bigger Bass Splash includes direct feature purchase options that skip the base game entirely. Updated, two purchase tiers exist:

Standard Feature Buy (100x total stake): triggers a guaranteed spin with at least 3 Scatter symbols, followed by the normal random allocation of 0 to 5 pre-bonus modifiers.
Super Free Spins Buy (350x total stake): triggers the bonus round with all five modifiers guaranteed and active at once (More Fish, More Fisherman, More Dynamites/Hooks/Bazookas, Start from Level 2 and +2 Extra Spins).

Under UK Gambling Commission remote technical standards, though, direct feature buys are prohibited on every UK-licensed gaming site, specifically to protect consumers from rapid financial depletion. The regulatory history is instructive:

«One operator charged more than £3,000 to enter a bonus round; after a UKGC warning in 2020, all six operators removed the feature.» — RTPTrack, timeline of UKGC regulatory action 2020–2026 (2024)

Where bonus buy functionality is available outside the UK market, buying a feature does not change the underlying theoretical RTP of the configured band. What it does change is session volatility, dramatically. Purchasing a £100 feature on a £1 base bet concentrates your total stake risk into a single spin cycle, and payouts can land well below the purchase price when fish collections fail to arrive. The 350x Super Buy stretches that asymmetry further: a £350 outlay on a £1 base stake commits more than three times the standard purchase into one round, and even with all five modifiers running the outcome is governed by the RNG, not by the price paid.

Jurisdiction note: Bonus Buy availability depends on the operator's jurisdiction. In the United Kingdom the feature is disabled at the regulator's requirement. Always confirm current rules on the specific casino's site.

Responsible Gambling & Risk Warning: Real-money slot play carries financial risk, and high-volatility games like Bigger Bass Splash can deplete a bankroll quickly during non-winning stretches. Feature purchases, where permitted, raise that risk by compressing large commitments into single rounds, and the Ante Bet lifts cost per spin by 50% without changing theoretical return. Gambling should never be treated as a source of income or a way to resolve financial difficulty. Set strict deposit limits, use session timers, and play only with funds you can afford to lose. 18+ · Play responsibly · BeGambleAware.org

How to evaluate Bigger Bass Splash before playing

Evaluating this fishing slot before you play means weighing its mathematical strengths, a competitive 96.50% default RTP and genuinely engaging pre-bonus modifiers, against the risks baked into a high-volatility structure. Check the game parameters, expect dry spells, and read the operator's rules before any cash wager.

Regulatory design rules also change how the game behaves in the UK compared with other markets:

«From 31 October 2021 the UKGC banned autoplay, spin speeds under 2.5 seconds, and sounds that celebrate returns below the stake.» — Flutter Entertainment SEC filing, summary of UKGC measures (2024)

Those constraints explain why Feature Buy is disabled in UKGC-regulated markets, why UK builds carry no autoplay button, and why a UK session covering 113 spins takes materially longer than the same volume in an unrestricted market. All of it is player protection rather than product limitation.

Pre-launch self-check:

Checklist before you start playing Bigger Bass Splash

I have checked the RTP in the casino's paytable (96.50% rather than 95.50% or 94.50%).
My bankroll covers at least 150–200 base stakes, given a ~1-in-113 bonus frequency.
I understand how the five pre-bonus modifiers and the 1x → 10x collection meter work.
I know whether Ante Bet is available and that it raises cost per spin by 50%.
I have set loss and session-time limits in line with responsible gambling practice.

The core trade-offs, summarised for an objective read:

Strengths (Pros):
- Competitive default RTP of 96.50%, aligned with top-tier online slots standards.
- Layered bonus features, including five pre-bonus modifiers and progressive collection multipliers up to 10x.
- Maximum win cap of 5,000x total stake, with a 400x Monster Truck as the strongest paytable symbol in the Big Bass series to date.
- Optional Ante Bet for players who prefer more frequent feature entries.
- Strong HTML5 mobile optimisation across iOS and Android.
Trade-offs & Limitations (Cons):
- High volatility brings long sequences with no meaningful payout and no fish collected (bonus averages once per ~113 spins).
- Base game payouts are modest, leaning heavily on free spins feature progression.
- Operator-configurable RTP bands (95.50% and 94.50%) may be deployed without prominent disclosure.
- Feature Buy is disabled in UKGC-regulated markets under player protection rules.
- Mechanically very close to Big Bass Splash, so franchise veterans may find the "bigger" branding overstated against the 5,000x cap it shares with its predecessor.

Where does that leave a cautious player? Bigger Bass Splash is a polished, genuinely dynamic entry in the fishing slot genre, and that is worth something. Approach it with a clear view of its probabilities, verify the operator's active RTP configuration, hold to a personal budget, and the entertainment value stays in your control rather than the paytable's.

Those constraints explain why Feature Buy

FAQ: Bigger Bass Splash questions answered

Can I play Bigger Bass Splash without a deposit?

Yes. The demo mode runs on virtual credits with no deposit required. UK-licensed operators may ask for registration and age verification before free play unlocks, and demo winnings carry no cash value.

What is the highest RTP version of the game?

96.50% is the default and highest certified band. Operators may also deploy 95.50% or 94.50%. The active figure appears in the in-game information panel.

How often does the bonus round trigger?

On average roughly once every 113–114 spins in the standard configuration. Activating the Ante Bet (+50% stake) increases that frequency, though the exact revised rate is not published.

What is the maximum win and how likely is it?

The cap is 5,000x the total stake. Published simulations estimate the probability of reaching it at about 1 in 1,683,555 spins, so treat it as a theoretical ceiling rather than a realistic target.

Which symbol pays the most?

The Monster Truck, worth up to 400x the total stake for five-of-a-kind on a payline. That is double the maximum paytable win of the original Big Bass Bonanza.

Is Bonus Buy available in the UK?

No. UK Gambling Commission rules prohibit direct feature purchases on UK-licensed sites. The 100x and 350x buy options exist only in permitted non-UK jurisdictions.

Does buying the bonus improve my returns?

No. The theoretical RTP stays the same, but variance rises sharply because a very large stake is compressed into one bonus round.

Is the demo identical to real-money play?

On licensed platforms, yes. The same RNG, paytable and volatility profile apply. Unlicensed third-party "practice" versions may run inflated returns, which research links to distorted risk perception.

How does it compare with other fishing-themed slots?

Against Fishin' Frenzy-style titles, Bigger Bass Splash offers a larger grid, a collection meter reaching 10x and pre-bonus modifiers. The trade-off is higher variance and a heavier reliance on the bonus round.

Corrections, methodology and version log

Methodology. Technical parameters in this review were cross-checked against the provider's published game information, operator paytables on UKGC-licensed sites, and independent review-laboratory data. Session observations (1,000 base-game spins; 50 mobile sessions) are internal ReelScope tests and are labelled as such wherever cited. They are illustrative and not a substitute for certified RNG testing by GLI or eCOGRA.

Appendix A, superseded statements retained for transparency:

Previous version: "High-Value Thematic — Pay 0.5x to 200x stake (Monster Truck pays for 2 to 5 matching symbols)." Correction: the Monster Truck pays up to 400x total stake for 5-of-a-kind; other premium thematic symbols top out at 200x.
Previous version: the Bonus Buy section listed only the 100x purchase. Correction: a Super Free Spins Buy at 350x total stake, awarding all five modifiers, also exists in permitted markets.
Previous version: no Ante Bet mechanic was documented. Correction: an optional +50% stake Ante Bet is available in operator builds that enable it.
Previous version: internal audit figures were presented without qualification. Correction: they are now explicitly labelled as non-certified, small-sample internal observations.
Previous version: maximum-win probability and mobile stability thresholds were stated without sourcing context. Correction: both are now attributed and flagged as modelled or internally observed rather than provider-certified.
