Bonanza

Bonanza is Big Time Gaming's landmark Megaways slot, with up to 117,649 ways to win and a reel system that can change the number of symbols in view from spin to spin. Winning symbols trigger Dual Reactions, so new symbols can arrive from more than one direction. The bonus is built around spelling GOLD with Scatters, after which Free Spins use a win multiplier that increases as reaction wins continue.

Bonanza at a glance

Bonanza is easiest to understand through three ideas: Megaways means the number of symbols on the reels can change, so the number of ways to win changes with the reel heights. Dual Reactions remove winning symbols and refill the board, allowing more wins in the same paid round. Free Spins add a multiplier that increases as reaction wins continue.

Inside the game

How Bonanza works

Bonanza is easiest to understand through three ideas: Megaways means the number of symbols on the reels can change, so the number of ways to win changes with the reel heights. Dual Reactions remove winning symbols and refill the board, allowing more wins in the same paid round. Free Spins add a multiplier that increases as reaction wins continue.

Megaways and variable ways

The provider lists a maximum of 117,649 ways to win.

That is a ceiling, not a fixed number of ways on every spin.

The reels can show different numbers of symbols, and the current reel heights determine how many ways are active for that spin. This is the key distinction between Megaways and a normal fixed-ways slot.

Dual Reactions

When a win occurs, the winning symbols are removed and replaced.

Bonanza's provider material describes this as a Dual Reaction system, with replacement action coming through the main reels and the horizontal reel/cart structure above the centre reels.

The useful player-facing idea is simple: a winning spin can continue without another bet because the board reacts and new symbols enter.

A reaction sequence ends when no new win forms.

GOLD Scatters and Free Spins

The bonus is triggered by spelling GOLD with four Scatter symbols.

The saved Help page confirms twelve initial Free Spins for four GOLD Scatters. Each additional triggering Scatter adds five more spins.

Free Spins multiplier

The Free Spins multiplier starts at 1× and rises by one after each reaction. It is carried through the bonus rather than waiting for a separate multiplier symbol to land.

The important distinction from Gates of Olympus 1000 is that this is not a random multiplier symbol dropping onto the reels. It is a running feature multiplier tied to the reaction sequence.

That makes Bonanza a useful comparison for players trying to understand different types of accumulating bonus multipliers.

Retriggers and extra spins

During Free Spins, Scatter symbols can appear in the top carts. Three award five extra spins and four award ten. The original triggering stake remains in use throughout the feature.

Bonus Buy availability

The recorded Relax distribution did not expose a Bonus Buy in its menu or captured Help pages. This observation belongs to that distribution; it does not establish availability or absence in every version.

This is the recorded Relax distribution v2.97.0-Relax. Big Time Gaming lists 96.00% RTP; the captured Help page shows the same overall value. No Bonus Buy was exposed in this session. A claim that another distribution offers it has no usable cached first-party evidence in this wave and is withheld; no buy cost is inferred.

05 / The SlotsCollector take

The SlotsCollector take on Bonanza

Bonanza is Big Time Gaming's landmark Megaways slot, with up to 117,649 ways to win and a reel system that can change the number of symbols in view from spin to spin. Winning symbols trigger Dual Reactions, so new symbols can arrive from more than one direction. The bonus is built around spelling GOLD with Scatters, after which Free Spins use a win multiplier that increases as reaction wins continue.

Bonanza matters because its headline "117,649 ways" is easy to quote and easy to misunderstand. The number is the maximum number of active ways, not a promise that every spin is evaluated across 117,649 combinations.

Megaways changes the reel heights. That means the shape of the board is part of the math you see on every spin. A low-way spin and a high-way spin are visibly different states of the same game.

The reaction system is the second piece. Once a win lands, the game removes the winning symbols and refills the board. That gives a single stake the chance to produce a chain of results. You are not watching six static reels resolve once; you are watching the reel state rebuild until the reaction sequence stops.

Free Spins then add the mechanic that made Bonanza especially memorable: the running multiplier. The multiplier grows as reaction wins occur. This creates a clear tension inside the bonus because a long chain can improve the multiplier before the next paying combination.

It is worth distinguishing this from multiplier-symbol games. There is no need to wait for Zeus or another special multiplier icon to land. The bonus itself owns the multiplier state, and reaction wins advance it.

The GOLD trigger is also unusually readable. Four Scatter letters spell the word across the reels and open the bonus. The visual language makes the feature easier to follow than a bonus where several unrelated symbol types feed the same meter.

The checked demo identifies itself as v2.97.0-Relax. Its Help page gives 96.00% overall RTP, twelve initial Free Spins and the reaction-based multiplier. Those concrete rules describe the distribution used for this guide.

The menu and all captured Help pages did not expose a Bonus Buy. That observation is limited to this distribution; it does not establish absence across every casino version.

Buy availability in other distributions is unconfirmed here, so no price is inferred. That leaves the normal GOLD trigger as the fully described route into Free Spins. Follow the top-cart Scatters, the opening spin count and the running reaction multiplier when learning how that bonus develops.

Separating observed menu availability from a universal feature claim keeps the guide useful when you compare it with the version at your casino.

As a playing experience, Bonanza remains much simpler than modern Megaways slots that stack several modifiers, meters and bonus menus on top of the variable reels. Most of the interest comes from reel height, reactions and the Free Spins multiplier. That simplicity makes it a useful reference point for comparing what later Megaways games added.

Players who like changing reel states and cascading wins can understand Bonanza quickly. Players looking for constant modifiers in the base game may find it sparse compared with newer Megaways releases. That contrast is valuable editorial content because it explains why the original still feels structurally different from its descendants.

Bonanza FAQ

What is Megaways in Bonanza?

Megaways means the number of visible symbols on the reels can change. Those reel heights determine the number of active ways to win on that spin.

How many ways to win can Bonanza have?

The provider lists a maximum of 117,649 ways.

Are there always 117,649 ways?

No. That is the maximum. The active number changes with the reel heights.

What are Dual Reactions?

Winning symbols are removed and new symbols enter the reels, allowing another win to form within the same paid round.

How do you trigger Free Spins?

The bonus is triggered by landing the four GOLD Scatter symbols.

How does the Free Spins multiplier work?

It starts at 1× and increases by one after each reaction. During Free Spins, three Scatters in the top carts add five spins and four add ten; the running multiplier stays with the bonus.

Does Bonanza have Bonus Buy?

No Bonus Buy was exposed in the recorded v2.97.0-Relax distribution. Availability in other versions is unconfirmed here, so no purchase price is inferred. The normal GOLD Scatter trigger remains available.
