Volatility High

Big Time Gaming transformed the slots landscape in 2016 with Bonanza Megaways, the game that took their Megaways mechanic from concept to global phenomenon. While Dragon Born Megaways technically launched the mechanic first, Bonanza captured the streaming world and became the title that defined high-volatility slots for years to come.

Set in a gold rush mining theme, the game positions players in the 19th century hunt for riches. What started as a cult favourite on Twitch streams has maintained its status through consistent gameplay and that signature unlimited multiplier mechanic during free spins.

Big Time Gaming has since pushed beyond Bonanza’s boundaries, with titles like Outlaw, Wild Flower, and Golden Catch Megaways reaching up to 64,000x stake. The remastered Bonanza now sits at 26,000x maximum win potential, significantly improved from the original 12,000x cap, positioning it as a more competitive option within the developer’s portfolio.

Base Game & Features

Bonanza operates on a 6-reel grid with variable row heights of 2-7 symbols per reel, generating up to 117,649 ways to win through the Megaways mechanic. The grid changes on every spin, creating dynamic payline configurations rather than fixed lines.

Horizontal Mining Cart Mechanic

A unique feature sits above reels 2, 3, 4, and 5: a horizontal mining cart containing an extra symbol position per reel. These four additional positions feed into the Megaways calculation and are where wild symbols exclusively appear, creating a distinctive mechanic that sets Bonanza apart from standard grid slots.

Symbol Structure

The paytable consists of precious stones in ascending value: emeralds, rubies, sapphires, and diamonds as the premium symbol. Gold symbols and card values (9 through A) fill out the lower-paying positions. The dynamite stick acts as the wild, substituting for all symbols except the scatter.

Reactions Mechanic

Winning combinations trigger a cascading reaction system. Symbols involved in wins explode and disappear, allowing new symbols to drop from above whilst the horizontal cart simultaneously shifts symbols into the vacant reel positions. This creates consecutive winning opportunities on a single paid spin, with reactions continuing until no new wins form.

Base game payouts cap at 50x stake, relatively modest for high-volatility gameplay. The reactions system provides frequent smaller hits with a 37.47% hit frequency, meaning wins occur approximately every 2.66 spins. This creates enough base game activity to offset the high volatility, though the real potential sits firmly in the bonus round.

Betting Structure

Stakes range from 0.20 to £5.00 per spin, accommodating recreational players whilst the relatively low maximum bet may limit high-stake appeal. The 96% RTP sits at industry average, neither generous nor restrictive, with variance carrying the weight of the gameplay experience rather than theoretical return.

Bonanza Megaways Free Spins

Triggering the Bonus

Free spins activate when landing four scatter symbols spelling GOLD (individual letters G, O, L, D) anywhere on the reels during a single spin. Each scatter beyond the initial four awards 5 additional free spins, so landing five scatters grants 17 total spins (12 base + 5 bonus), and six scatters delivers 22 spins.

Research indicates bonus trigger frequency sits around 450-1,300+ base game spins, creating the feast-or-famine experience typical of high-volatility slots. Players report significant dry spells between bonus rounds, requiring mental preparation for extended sessions without features.

Bonus Buy Option

A 90x stake bonus buy allows direct access to free spins without waiting for natural triggers. At 90x cost, this sits competitively within the bonus buy market, though the high-volatility nature means even purchased bonuses can return less than the buy-in cost.

Unlimited Win Multiplier

The defining feature of Bonanza free spins is the unlimited progressive multiplier. Starting at 1x, the multiplier increases by 1 with every reaction win during the bonus round, with no cap on maximum height. Early consecutive wins can build substantial multipliers by mid-feature, and if reactions continue, multipliers reaching 20x, 30x, or beyond become possible.

This unlimited mechanic is what enables the 26,000x maximum win potential. Extended reaction chains with high multipliers applied to premium symbol wins create the explosive payouts that made Bonanza a streaming phenomenon. The multiplier resets only when free spins end, maintaining its value across all awarded spins including retriggers.

Retriggers

Landing 3 scatter symbols during free spins awards 5 additional spins. Landing 4 scatters grants 10 extra spins. Importantly, the multiplier does not reset on retrigger, continuing its progressive climb across all extended spins. Retriggers are unlimited, theoretically allowing indefinite free spin extension though probability makes extensive chains rare.

During the bonus round, the visual environment shifts to an underground mining setting with gold bars appearing in the horizontal mining carts, reinforcing the thematic coherence between game design and mechanics.

Our Honest Verdict

Bonanza Megaways remains a high-volatility benchmark nearly a decade after launch, though its position within Big Time Gaming’s portfolio has shifted. The remastered 26,000x maximum win (up from the original 12,000x) makes it more competitive against newer releases, though it still trails the developer’s 64,000x titles.

The unlimited multiplier mechanic during free spins is where Bonanza justifies its reputation. Extended reaction chains with climbing multipliers create genuine tension, and the lack of a multiplier cap means theoretical win potential remains unconstrained. However, the 450-1,300+ spin bonus trigger frequency demands patience and bankroll depth that won’t suit all players.

Base game pacing feels restrained with its 50x maximum payout, though the 37.47% hit frequency provides enough activity to maintain engagement between bonus rounds. The £5.00 maximum bet will disappoint high-stakes players, positioning this firmly in the recreational to mid-stakes space.

Who This Suits

High-volatility chasers who can weather extended dry spells for explosive bonus potential will find Bonanza delivers on its promise. Those seeking consistent base game action or frequent bonus triggers should look elsewhere. The 90x bonus buy provides an alternative entry point, though it doesn’t eliminate the variance inherent in the feature itself.

Final Positioning

Bonanza holds its ground through mechanical simplicity and proven bonus potential rather than innovation. It won’t satisfy players seeking cutting-edge features or massive 50,000x+ caps found in contemporary releases, but the unlimited multiplier system remains effective. For those familiar with the game’s rhythm and volatility profile, it continues to deliver what made it a streaming staple.

Rating: 7.5/10
