96.0%	Extreme	21,175x	117,649	Big Time Gaming	2016

Every Megaways game in existence (and there are more than 500 of them) traces back to one slot. In 2016, Big Time Gaming released Bonanza (a 96.0% RTP, 21,175x max win extreme-volatility slot) with a mechanic that had never appeared in a commercial slot before: a variable reel height. Each of the six reels could display between 2 and 7 symbols on any given spin, chosen randomly. The ways-to-win count changed on every spin rather than staying fixed. When all six reels showed 7 symbols at once, the math produced 7 to the power of 6: 117,649 ways to win. Nothing like that existed before. Within four years, more than 40 studios had licensed the mechanic from BTG. By 2023, the industry counted over 500 Megaways titles. Gonzo’s Quest Megaways, Buffalo Megaways, Monopoly Megaways: every single one of them is possible because of Bonanza.

The Megaways Origin: What Big Time Gaming Invented

Before 2016, every slot reel showed the same number of symbols on every spin. Three symbols per reel, four symbols per reel: fixed, predictable, unchanging. The ways-to-win count was a constant determined by the grid layout. Big Time Gaming’s Matt Booth broke that assumption by making the reel height a random variable.

On each spin in Bonanza, every reel independently determines how many symbols it will show: any value from 2 to 7. A reel showing 2 symbols covers a narrow vertical strip. A reel showing 7 symbols covers the full column height. The ways-to-win calculation multiplies the symbol count across all six reels. A spin where the reels show 4, 3, 7, 5, 2, 6 symbols produces 4 x 3 x 7 x 5 x 2 x 6 = 5,040 ways. The next spin might show 7, 7, 7, 7, 7, 7 and produce 117,649 ways. The spin after that might show 2, 2, 2, 2, 2, 2 and produce just 64 ways. The ways count is a new random variable on every spin.

This was a genuine structural change to how slot mathematics work. It was not an incremental improvement to an existing format. The Megaways patent covered this mechanic, and BTG licensed it to other studios from around 2018 onward. Red Tiger, Pragmatic Play, Blueprint Gaming, and NetEnt all licensed Megaways. The royalty model made BTG one of the most commercially significant slot studios in the world despite having a relatively small game library compared to larger providers.

Bonanza is where all of that started. The mine theme, the gold rush setting, the cascading reels are all memorable. The variable reel height is what changed the industry.

The Mine Reel: Bonanza’s Unusual Free Spins Trigger

Most slot free spins bonuses are triggered by scatter symbols landing on the main reels. Bonanza does it differently. A horizontal mine reel sits above reels 2, 3, 4, and 5. Each spin, this reel displays 4 symbols. Those symbols can include the letters G, O, L, and D among other characters.

When the 4 symbols displayed on the mine reel spell G-O-L-D from left to right, free spins trigger. There are no scatter symbols on the 6 main reels. The trigger is determined entirely by what the mine reel shows on that spin.

The structural implication is significant. With scatter triggers, the probability of triggering scales with the number of scatter symbols on the reel strips and the number of scatters required to land. With the mine reel, the probability is determined by the frequency of G, O, L, D letters in the mine reel’s symbol pool. The mine reel is a fixed 4-symbol display, not a set of scatter positions spread across a 6-reel grid. This design makes Bonanza’s trigger mechanism genuinely distinct from every other major Megaways title released after it.

Landing GOLD on the mine reel during the free spins round retrigggers additional free spins. The retrigger uses the same mechanism: the mine reel must again show G-O-L-D while the bonus is active.

Bonanza Free Spins and the Unlimited Cascade Multiplier

Triggering free spins awards 12 initial spins. The free spins round includes a cascade multiplier that is the core driver of Bonanza’s top win potential.

At the start of free spins, the multiplier is 1x. Each cascade during the bonus adds 1x to the multiplier. A cascade occurs when a winning combination is removed from the grid and new symbols fall into the vacated positions, potentially creating further wins. Multiple cascades can occur within a single spin.

The critical detail: the multiplier never resets. It does not reset between individual free spins. It does not reset between cascade sequences within a single spin. If spin 1 of the bonus produces 3 cascades, the multiplier reaches 4x and stays at 4x for spin 2. If spin 2 produces 2 cascades, the multiplier reaches 6x for spin 3. A free spins round with consistent cascading across all 12 spins can accumulate a multiplier of 20x or higher before the bonus ends.

Consider a worked example: free spins begin at 1x. Spin 3 produces 5 cascades. The first cascade occurs at 3x (accumulated from earlier spins), and each subsequent cascade in that sequence adds 1x: 3x, 4x, 5x, 6x, 7x. The fifth cascade in that sequence lands at 7x. A high-value combination covering all 6 reels at 117,649 ways at 7x multiplier produces a substantially larger win than the same combination at 1x. By spin 10 at a 15x accumulated multiplier, a maximum-ways high-value cascade produces the kind of outcome that drives Bonanza’s ceiling.

The maximum win is cited at 21,175x stake. Reaching that figure requires a combination of a high accumulated multiplier from extensive cascading and a full-grid high-value combination at close to maximum ways. The multiplier has no stated ceiling; the 21,175x cap is a hard limit in the game’s math rather than a ceiling on the multiplier itself.

Bonanza Megaways RTP: 96.0% at Extreme Volatility

The Bonanza Megaways RTP is 96.0%. That figure is solid without being exceptional. For context, many extreme volatility slots cluster between 95.0% and 97.0% RTP. Bonanza sits comfortably in the middle of that range.

What matters more than the headline RTP at extreme volatility is the distribution. In high-volatility games, the theoretical return is weighted heavily toward the bonus round. Base game wins in Bonanza are frequent enough to generate some activity, but the session-defining wins come through the free spins cascade multiplier. A player who triggers the bonus multiple times in a session and experiences extended cascade chains is receiving a disproportionate share of that 96.0% return during those sessions. A player who spins for a session without triggering the bonus or with short cascade chains receives a much smaller share.

This distribution is typical of extreme volatility titles. The 96.0% is a long-run mathematical average. Short-run variance around that average is wide, which is what “extreme volatility” means in practice.

Because Bonanza has no feature buy, every session begins with base game play. There is no option to convert bankroll directly into bonus access. Budget management matters more in this game than in feature-buy slots because the time between bonuses depends entirely on the mine reel trigger frequency.

Bonanza Megaways Max Win: 21,175x Explained

The Bonanza Megaways max win of 21,175x is produced by a specific configuration: a high accumulated cascade multiplier in free spins combined with a maximum-ways, high-value symbol combination on the main reels.

The cascade multiplier is the variable that makes the max win possible. Without an accumulated multiplier from extensive cascading, even a full-grid highest-value combination at 117,649 ways does not reach 21,175x. The multiplier must be substantial, likely in the range of 15x to 20x or higher, for a single cascade win to approach the maximum.

How does that compare to Extra Chilli Megaways, the other original BTG Megaways title? Extra Chilli’s equivalent cap is cited at approximately 20,000x+, similar in magnitude. Both games use the same unlimited, non-resetting cascade multiplier in free spins and the same 117,649 maximum ways to win. The practical difference in max win ceiling is small. The structural differences between the two games (trigger mechanism, feature buy availability, Ante Bet) matter more to most players than the marginal difference in theoretical maximum.

Bonanza vs Extra Chilli Megaways

Both games are original Big Time Gaming Megaways titles. Extra Chilli arrived after Bonanza, with player feedback from Bonanza’s early success incorporated into the design. The feature buy and Ante Bet in Extra Chilli were responses to players who found Bonanza’s trigger mechanism opaque and the wait between bonuses frustrating.

Feature	Bonanza	Extra Chilli Megaways
Release year	2016	2018
Max win	21,175x	~20,000x+
Trigger mechanism	Mine reel GOLD sequence	Scatter symbols on main reels
Feature buy	No	Yes
Ante Bet	Operator dependent	Yes (standard)
Cascade multiplier	Unlimited, never resets	Unlimited, never resets
RTP	96.0%	96.2%
Max ways	117,649	117,649

The practical choice between the two games comes down to what a player values. Players who want direct control over bonus access should use Extra Chilli’s feature buy. Players who want the original Megaways experience, including the mine reel trigger that feels genuinely different from scatter-based games, should play Bonanza. Both games share the same cascade multiplier structure and the same maximum ways count. The core math of what drives the biggest wins is identical.

The Megaways Licensing Legacy

BTG’s decision to license the Megaways mechanic rather than keep it exclusive transformed the slot industry. From around 2018, studios paid BTG a royalty to use the Megaways system. Red Tiger released Dragon’s Fire Megaways. Blueprint Gaming built Fishin’ Frenzy Megaways. NetEnt adapted Gonzo’s Quest into Gonzo’s Quest Megaways. Pragmatic Play built an entire Megaways sub-catalogue.

By 2020, Megaways had become a genre rather than a mechanic. Players searched for “Megaways slots” as a category. Operators curated Megaways sections. The licensed mechanic became a marketing term.

The BTG royalty model gave the studio recurring revenue from every Megaways spin across every licensed game at every operator globally. That commercial success funded further BTG original development including White Rabbit Megaways, Danger High Voltage, and Extra Chilli itself.

All of that revenue, all of that game development, all of those 500+ Megaways titles: they originated from one mechanic, in one game, released in 2016. Bonanza is not historically significant despite being a good slot. Bonanza is historically significant because it changed the structure of how slot reels work.

FAQ

What is the RTP of Bonanza Megaways?

The Bonanza Megaways RTP is 96.0%, certified by Big Time Gaming. This applies to all spins including the free spins round. Because the original Bonanza has no feature buy option, every session runs at the standard 96.0% rate. The free demo at Flush runs on the same RNG as real-money play at this RTP.

What is the Bonanza Megaways max win?

The Bonanza Megaways max win is 21,175x stake. Reaching this ceiling requires extensive cascading during free spins to build the unlimited multiplier, combined with a maximum-ways high-value symbol combination. The multiplier starts at 1x and increases by 1x with every cascade event during free spins and never resets within the bonus round.

How do Bonanza free spins trigger?

Free spins trigger when the horizontal mine reel above reels 2 through 5 displays G, O, L, D in sequence during any base-game spin. This is not a scatter trigger, Bonanza has no scatter symbols. Twelve free spins are awarded. Spelling GOLD again on the mine reel during the bonus adds more free spins. The unlimited cascade multiplier is active for the full bonus.

How does the Megaways mechanic work in Bonanza?

Each of Bonanza’s six reels independently displays between 2 and 7 symbols per spin, chosen randomly. The ways-to-win count is the product of all six reel symbol counts. When all six reels show 7 symbols simultaneously, the result is 7 to the power of 6, producing 117,649 ways. This variable reel height system was created by Big Time Gaming in 2016 and was the first commercial implementation of the Megaways mechanic.

Can I play Bonanza Megaways at Flush?

Yes. Bonanza Megaways is available at Flush casino with the full free demo accessible without registration. Select Demo mode from the Flush game lobby to play with practice credits. For real-money play, deposit using BTC, ETH, USDT, TRX, or SOL. Flush processes all withdrawals in the same cryptocurrency used for deposit with no conversion fees. The full 96.0% RTP applies at Flush.

Mechanic Deep Dive

The Megaways mechanic generates a random number of symbols per reel on each spin. With 6 reels each showing 2 to 7 symbols, the total ways-to-win is the product of all six reel symbol counts. The minimum configuration (all reels showing 2 symbols) produces 2 x 2 x 2 x 2 x 2 x 2 = 64 ways. The maximum configuration (all reels showing 7 symbols) produces 7 x 7 x 7 x 7 x 7 x 7 = 117,649 ways.

The probability distribution of Megaways counts in any given spin peaks around 20,000 to 40,000 ways rather than the advertised 117,649 maximum. Full 117,649 ways occurs less than 1% of spins. On a typical spin, expect 10,000 to 50,000 active ways depending on reel heights. The counter visible in the game displays the current ways count for that spin, so players can see the exact active ways before evaluating win potential.

The Reactions (cascade) mechanic removes winning symbols after each win and drops new symbols from above to fill the empty positions. If the new symbols create another winning combination, that combination pays and another reaction occurs. Reaction chains can produce multiple wins from a single spin’s initial bet, with each reaction paying independently before the chain resolves.

In Bonanza’s free spins, the cascade multiplier adds +1 with every reaction. The multiplier does not reset between spins within the bonus round. A bonus round producing 3 reactions per spin across 8 spins accumulates a multiplier of 25x (1 base + 24 reaction increments). That 25x applies to every subsequent reaction within the same bonus, meaning the later spins in a high-cascade bonus run are worth dramatically more than the early spins.

The GOLD mine reel that triggers free spins sits horizontally above reels 2 through 5. It spins independently and must display G, O, L, D in sequence for the trigger to fire. This is structurally distinct from scatter-triggered bonuses in that the mine reel is the sole trigger mechanism, there are no scatter symbols on the main reels. The mine reel contains multiple symbols including non-GOLD characters, and the probability of GOLD forming across the 4 positions is determined by the frequency of those letters on the reel strip.

Paytable Reference

Bonanza uses a gem-themed symbol set on its 6-reel Megaways grid. Higher-value symbols produce disproportionately large wins at high ways counts combined with a built-up cascade multiplier.

Symbol	3-of-a-kind	4-of-a-kind	5-of-a-kind	6-of-a-kind (max ways)
Diamond (top)	0.5x	1x	2x	5x
Gold Mine	0.4x	0.8x	1.5x	4x
Ruby	0.3x	0.6x	1x	3x
Emerald	0.2x	0.4x	0.8x	2x
Sapphire	0.2x	0.4x	0.8x	2x
Card A	0.1x	0.2x	0.4x	1x
Card K	0.08x	0.15x	0.3x	0.8x
Card Q	0.05x	0.1x	0.2x	0.5x
Card J	0.05x	0.1x	0.2x	0.5x
Card 10	0.05x	0.1x	0.2x	0.5x

With 117,649 ways active and a cascade multiplier at 5x during free spins, a single Diamond combination on all 6 reels produces 5 x 5 = 25x from one combination on one reaction. At 10x multiplier on 100,000 active ways, the same combination produces 10 times as much. The path to the 21,175x max win requires sustained cascade activity in the bonus building the multiplier to 15x or higher before the highest-value combination occurs.

Series Comparison

Bonanza vs Extra Chilli Megaways:

Feature	Bonanza	Extra Chilli Megaways
RTP	96%	96.19%
Max Win	10,000x	20,000x
Ways	Up to 117,649	Up to 117,649
Free Spins Multiplier	Unlimited (cascade)	Unlimited (cascade)
Gamble Feature	No	Yes, bet spins for multiplier start
Reaction Mechanic	Yes	Yes
Feature Buy	No (most operators)	Yes
Ante Bet	No	Yes (25% for 2x scatter frequency)
Free Spins Trigger	Mine reel GOLD	4+ scatter symbols on main reels
Release Year	2016	2018

Extra Chilli Megaways is the more player-configurable game. It adds a Feature Buy, an Ante Bet, and uses scatter-based triggering rather than the mine reel. The cascade multiplier structure is identical in both titles. Extra Chilli has a slightly higher RTP at 96.19% versus Bonanza’s 96%. For players who want direct control over bonus access, Extra Chilli is the practical choice. For players who want the original Megaways experience with the mine reel trigger, Bonanza is the historical choice.

Bankroll Requirements

Bonanza carries Extreme volatility without a Feature Buy option, meaning all session value is reached through organic play. Long base game sessions before triggering are standard.

Session Type	Minimum Units	Recommended Units	Notes
Base game exploration	200	400	Observe mine reel frequency
Standard session	300	600	Very High vol, long dry spells normal
Extended session	500	800	Multiple bonus trigger expectation
Conservative	600	1000	Wide variance buffer, no feature buy safety valve

No Feature Buy means no shortcut to the bonus. Budget all units as organic base game spins. At Extreme volatility, sessions of 200 to 300 spins without triggering the GOLD mine reel are realistic. USDT deposits at Flush provide clean session accounting. The cascade multiplier resets at the start of each new free spins trigger, so bankroll efficiency in Bonanza is about reaching more bonus triggers rather than entering any single bonus with elevated conditions.

Provider Profile: Big Time Gaming and the Megaways Patent

Big Time Gaming was founded in Sydney, Australia, in 2011. The studio released a modest catalog of standard slot titles before Matt Booth developed the Megaways mechanic internally. Bonanza, released in 2016, was the commercial launch of the mechanic and remains the most historically significant slot Big Time Gaming has released.

The patent covering the Megaways variable reel height mechanic was filed by BTG in 2016. The studio began licensing the mechanic to other studios from approximately 2018, initially to Red Tiger Gaming and Blueprint Gaming. The licensing model created a revenue stream from every spin of every licensed Megaways game at every operator globally. By 2021, Red Tiger (later acquired by NetEnt and subsequently Evolution) had built one of the largest Megaways catalogs under license.

The BTG acquisition by Scientific Games (now Light and Wonder) in 2021 brought the Megaways patent into a larger corporate structure, but the licensing model continued operating through BTG as a distinct studio. The studio’s own game output under the Megaways banner included White Rabbit Megaways, Danger High Voltage, Extra Chilli, and several branded titles. All of these share the core variable-reel-height mechanic that Bonanza introduced.

Session Dynamics: Playing Bonanza Without a Feature Buy

Bonanza is one of the few high-profile Megaways slots that does not offer a Feature Buy in standard configurations. This absence has practical implications for session planning that differ meaningfully from Feature Buy-enabled titles.

Without a Feature Buy, every unit of session bankroll must be allocated to base game spins. There is no mechanism to skip the base game and purchase direct bonus access. The mine reel GOLD sequence must trigger organically. This means the time between bonus rounds is a function of mine reel symbol distribution and spin count rather than a player decision.

In practical session terms, Bonanza requires more patience than Extra Chilli Megaways or other feature-buy-enabled Megaways titles. A session targeting 3 bonus triggers needs enough base game bankroll to sustain approximately 180 to 270 base game spins at average trigger frequency (estimated at 60 to 90 spins per trigger, though actual frequency varies). At a 1 USDT stake, that is 180 to 270 USDT in base game wagering before the third bonus trigger on average.

The tradeoff: base game spins in Bonanza contribute to the session experience through Reaction chains and frequent small symbol wins. The mine reel GOLD sequence builds anticipation differently from scatter symbols because players watch the horizontal reel for letter accumulation across spins. G appears on spin 1. Several blank spins pass. O appears. The partial GOLD sequence creates tension across multiple spins rather than resolving in a single scatter-landing event.

Cascade Multiplier Strategy in Free Spins

The unlimited cascade multiplier in Bonanza free spins creates asymmetric value distribution across the bonus round. Early free spins have a low multiplier and produce relatively modest payouts even from strong symbol combinations. Later free spins carry the accumulated multiplier from all prior cascades and produce disproportionately large payouts from the same symbol combinations.

This means retriggers during free spins are particularly valuable: each additional spin added by a mine reel GOLD sequence during the bonus extends the high-multiplier portion of the round rather than adding spins at the beginning. A retrigger that adds 4 spins when the multiplier is already at 15x adds 4 spins at 15x and above rather than 4 spins at 1x to 5x. The relative value of late retriggers is higher than early retriggers.

Budget accordingly: long free spins sessions with multiple retriggers are the highest-value Bonanza outcomes. A 20-spin bonus with the multiplier reaching 25x by spin 18 produces the majority of its total output in the final 3 to 5 spins. Watching the multiplier counter in the bonus round is the most useful real-time information Bonanza provides about the current session’s win trajectory.

Megaways Count Distribution and Why 117,649 Is the Exception, Not the Norm

The 117,649 maximum ways-to-win figure in Bonanza is the number that appears on every review and in every marketing description. It is accurate, and it is misleading. Maximum ways require every one of the six main reels to show 7 symbols simultaneously on the same spin. The probability of that specific configuration is low: each reel independently generates its height from 2 to 7, and the chance of all six simultaneously landing at 7 is a small fraction of possible outcomes. In practice, full 117,649 ways occurs on fewer than 1% of spins.

The practical distribution of Megaways counts clusters between 15,000 and 60,000 ways on most spins. A typical spin might show reel heights of 4, 5, 6, 5, 4, 6, producing 4 x 5 x 6 x 5 x 4 x 6 = 14,400 ways, or reel heights of 5, 6, 7, 5, 6, 5 producing 5 x 6 x 7 x 5 x 6 x 5 = 31,500 ways. These are the ordinary outcomes. The 117,649 spin exists in the game, players do land it, but it is a distinct event rather than the baseline expectation. The ways counter displayed on screen during each spin shows the exact active ways for that specific spin, which is the most informative number available in real time.

This distribution matters because Bonanza is not a “117,649 ways every spin” game in practice. It is a game that varies constantly between lower counts and occasional high counts, with the free spins cascade multiplier providing the mechanism by which high-ways spins become valuable. A spin at 40,000 ways with a 12x accumulated multiplier is substantially more valuable than a 117,649-ways spin at 1x multiplier without cascades. Understanding the ways count as a variable rather than a fixed maximum changes how a player reads each spin: the active ways counter is more informative than the theoretical maximum.

How the Scatter Trigger Actually Works

Free spins in Bonanza require the four GOLD scatter letters to appear across the horizontal top reel strip. The top reel is a separate, fixed-width reel that runs above reels 2, 3, 4, and 5 of the main grid. It displays 4 symbols per spin. The scatter letters G, O, L, and D are exclusive to this top reel strip. They do not appear on the main six reels at all. When the top reel displays all four letters spelling G-O-L-D from left to right, the 12 free spins bonus triggers. Landing only one, two, or three of the letters does not trigger the bonus: all four must appear in sequence on the same spin.

This structure explains why Bonanza’s trigger frequency feels different from scatter-based Megaways games. In a standard scatter trigger, scatters can land across a 6-reel grid of many positions. In Bonanza, the trigger depends entirely on a single 4-symbol horizontal reel, and all four symbols must be the correct letters in the correct sequence. The result is a trigger frequency of approximately one bonus per 300 to 400 spins, which is notably longer than most scatter-triggered Megaways titles. A 200-spin session at Bonanza carries a meaningful probability of zero bonus triggers. A 400-spin session is more likely than not to produce one or two.

Cascade Mechanics: Symbols Fall from Above

The cascade mechanic in Bonanza, called Reactions by Big Time Gaming, works vertically. When a winning combination is removed from the grid, new symbols generate from above and fall downward into the vacated positions. This top-down symbol generation is the standard cascade direction in Megaways titles and differs from side-entry cascade mechanics found in some other games. Each cascade pays independently. Multiple cascades from a single spin’s initial bet pay out sequentially before the next spin begins.

During the free spins bonus, each cascade adds 1x to the running multiplier. The multiplier never resets within the bonus round, neither between individual free spins nor between cascade sequences within the same spin. A free spins round that generates 8 cascades across its first 4 spins carries a 9x multiplier (1 base plus 8 cascade increments) into spin 5. From that point forward, every cascade in the remaining spins occurs at 9x or higher. This asymmetric value distribution, where later spins in a high-cascade bonus are worth many times more than early spins, makes retriggers during the bonus particularly valuable: each additional spin added by a retrigger arrives when the multiplier is already elevated.

No Bonus Buy: Why It Was Never in the Original

Bonanza does not include a Feature Buy option. This is a deliberate structural choice made by Big Time Gaming at launch in 2016, before the Feature Buy mechanic had become standard in the slot industry. BTG subsequently introduced Feature Buy in later titles including Extra Chilli Megaways and White Rabbit Megaways, but has retained the original Bonanza in its launch configuration. The absence of Bonus Buy means every unit of session budget must be committed to organic base game play. There is no mechanism to purchase direct access to the free spins round. Players targeting the bonus must spin through the base game until the GOLD top reel sequence triggers naturally, however long that takes.

The practical consequence: Bonanza sessions require larger bankrolls than Feature Buy-enabled Megaways titles of equivalent RTP, because all session budget is exposed to base game variance before the bonus becomes accessible. At 300 to 400 spins per trigger on average, a session expecting two bonus rounds requires 600 to 800 base game spins of coverage before the second bonus is statistically likely to arrive. At a $0.50 per spin stake, that is $300 to $400 of base game wagering per two-trigger expectation. The Extreme volatility rating reflects this structure directly.
