Big Time Gaming: Inventors of Megaways and High-Volatility Slots

Last updated: 2026-05-10

Quick take: Best suited to players who want high volatility, big multipliers, and huge max-win potential. Not ideal for short sessions or tight bankrolls.

Big Time Gaming (BTG) is an Australian studio founded in 2011. They built their reputation by creating mechanics that other developers now license and build on. Their games run high volatility, which means long dry spells are normal — but when a bonus lands, the payouts can be enormous. At Slottomat you can play the full BTG catalog in demo mode. No account. No deposit.

The Studio That Invented Megaways

BTG introduced the Megaways mechanic in 2016. Dragon Born was the world's first Megaways slot, released in February 2016. Later that year, Bonanza launched in December and became the title that put Megaways on the map. Both use a variable-reel system where the number of symbols on each reel changes every spin, creating up to 117,649 ways to win. The mechanic was so popular that BTG patented it and began licensing it to other studios. Today dozens of developers use it, but BTG created it.

Signature Mechanics

Most BTG games share a few core features. Cascading reels remove winning symbols and drop in new ones, chaining multiple wins from a single spin. Free spins rounds often include an unlimited multiplier that climbs with each cascade. Many titles also offer a Feature Drop (bonus buy), letting you pay to enter the bonus round directly. Beyond Megaways, BTG developed the Megaclusters engine — used in Diamond Fruits and Cyberslot Megaclusters — where symbols split into smaller ones to create cluster wins.

RTP across the catalog typically sits at 96–97%, which is at or above the 96% industry average. Volatility is consistently high. Plan for variance and set a session budget before you play.

RTP and Volatility: What to Expect

BTG games are built for high volatility. That means you can spin through a long stretch without a meaningful win, then land a free-spins round where multipliers climb into the hundreds. The max win in titles like Bonanza can exceed 10,000x your stake. For context, the 96% RTP on most BTG games is solid compared to the industry average — but the variance is the real story. Small bets and longer sessions give the bonus rounds time to land.

Beyond Megaways: Other BTG Engines

BTG didn't stop at Megaways. Megaclusters splits symbols into smaller versions each time a cluster lands, creating a grid that grows denser as wins chain. Megaquads divides the screen into four synced grids — see Slot Vegas Megaquads. The Megapays system, found in Bonanza Megapays, layers a four-tier progressive jackpot on top of the Megaways base. Each engine plays differently and is worth trying on its own terms.

The Pioneers Who Revolutionized Online Slots Forever

When Big Time Gaming (BTG) launched in 2011, few could have predicted that this Sydney-based studio would fundamentally transform the entire online slots industry. Founded by industry veterans Nik Robinson, Huw McIntosh, and Ian Schmidt—professionals with combined experience dating back to the late 1990s—BTG brought a fresh perspective to slot development. While other studios focused on volume, BTG concentrated on innovation, and in 2015, they released something that would change gaming history: the world's first Megaways slot, Dragon Born.

Though Dragon Born introduced the groundbreaking Megaways mechanic, it was the 2016 release of Bonanza that ignited a revolution. This mining-themed masterpiece didn't just popularize Megaways—it established an entirely new standard for what slots could achieve. Today, Big Time Gaming stands as one of the most influential forces in online gaming, with their Megaways engine licensed to over 20 major providers and featured in thousands of slots worldwide. In 2021, Evolution Gaming recognized BTG's extraordinary value, acquiring the studio for €450 million.

Understanding the Megaways Phenomenon

The Megaways mechanic represents the most significant innovation in slot gaming since the introduction of video slots themselves. Unlike traditional slots with fixed paylines, Megaways uses a random reel modifier system that changes the number of symbols appearing on each reel with every single spin. In the standard six-reel configuration, each reel can display between two and seven symbols, creating anywhere from 64 to an astounding 117,649 ways to win on any given spin.

This mathematical brilliance creates unprecedented variety and excitement. No two spins ever feel identical—one moment you might have a minimal number of ways to win, the next spin could explode with maximum Megaways and cascading reactions. The unpredictability keeps players genuinely engaged, transforming each spin into a unique event rather than a repetitive action.

Recognizing the mechanic's potential, BTG made the strategic decision to license Megaways to other developers in 2018, starting with Blueprint Gaming. This licensing program has proven phenomenally successful, with major providers including Pragmatic Play, NetEnt, Red Tiger, Blueprint Gaming, iSoftBet, and many others now creating their own Megaways titles. The mechanic has become the most widely adopted slot engine in the industry, generating substantial licensing revenue for BTG while giving players access to thousands of Megaways variations across countless themes.

Legendary Slots That Defined an Era

Bonanza remains the title that launched the Megaways revolution into the mainstream. Set in a gold mine with charming cartoon graphics, this 2016 release features up to 117,649 ways to win, cascading reels (which BTG calls Reactions), and an unlimited win multiplier during free spins. The multiplier increases by one with every cascade and has no cap, creating the potential for truly massive wins during extended reaction sequences. Bonanza's enduring popularity has made it one of the most-played slots globally, maintaining top-tier status years after release.

Extra Chilli took everything players loved about Bonanza and amplified it. This Mexican market-themed sequel introduced the innovative Feature Drop option, allowing players to purchase direct entry to the bonus round. The game's most distinctive feature is the free spins gamble, where players can risk their triggered spins for a chance at more—starting with eight free spins, you can gamble up to 24. The initial gamble offers a 50/50 chance, while subsequent gambles tilt 60/40 in your favor, creating genuine tension and strategy. With up to 117,649 Megaways and a maximum win potential of 50,000x your stake, Extra Chilli delivers extreme volatility and enormous payout possibilities.

White Rabbit transported players down the rabbit hole with an Alice in Wonderland theme and introduced the revolutionary Extending Reels mechanic. During the free spins feature, cupcake symbols can land and extend reels up to 12 symbols high, creating an incredible 248,832 ways to win—more than double the standard Megaways maximum. When any reel reaches the full 12 symbols, players receive additional free spins. With an RTP ranging from 97.24% to 97.77% depending on the Feature Drop option, White Rabbit offers exceptional return rates alongside innovative gameplay.

Who Wants to Be a Millionaire Megaways showcased BTG's ability to create compelling branded content. This officially licensed adaptation of the iconic TV game show successfully translates the program's format into slot mechanics, featuring lifelines like "Ask the Audience" and "Phone a Friend" as bonus features. The game maintains the tension and excitement of the original show while delivering up to 117,649 Megaways and multiple bonus rounds that mirror the show's progression format.

Danger High Voltage demonstrates BTG's range beyond Megaways. Inspired by the Electric Six rock song, this high-voltage slot features two distinct free spin variations—High Voltage Free Spins offering up to 15 spins, and Gates of Hell Free Spins providing seven spins with sticky wilds and multipliers up to 66x. The game's rock-and-roll theme and alternative gameplay mechanics prove BTG's innovation extends beyond their signature Megaways engine.

Signature Features and Game Design Philosophy

Big Time Gaming slots share several hallmark features that define the BTG experience. The Reactions feature—equivalent to cascading reels or avalanches—sees winning symbols removed from play, allowing new symbols to drop down and potentially create consecutive wins from a single spin. During bonus rounds, these reactions become even more powerful when combined with increasing multipliers.

Unlimited win multipliers during free spins represent another BTG trademark. Games like Bonanza and Extra Chilli feature multipliers that increase with every cascade and have absolutely no upper limit. This creates the mathematical possibility for astronomical wins during lucky streaks with extended reaction sequences. The combination of Megaways, cascading reactions, and unlimited multipliers generates BTG's characteristic extreme volatility and massive win potential.

The Feature Drop (also known as Feature Buy) option allows players to purchase direct entry to bonus rounds, typically costing between 50x and 100x the base bet. This feature appeals to players who prefer skipping the base game to access high-action free spins immediately. Importantly, games with Feature Drop often display different RTP percentages for base game versus purchased features, with the bonus buy sometimes offering slightly higher return rates.

Mathematics, RTP, and Volatility

Big Time Gaming has built its reputation on creating high to extreme volatility slots designed for players who appreciate substantial risk-reward dynamics. The high volatility profile means wins occur less frequently but arrive with significantly larger values when they hit. This mathematical approach attracts experienced players seeking the thrill of potentially life-changing payouts rather than frequent small wins.

Return to Player (RTP) percentages across BTG's portfolio typically range from 96% to well over 97%, competitive with or exceeding industry standards. White Rabbit leads with up to 97.77% RTP, while Extra Chilli offers 96.82%, and Bonanza sits at approximately 96%. These solid return rates combined with high volatility create games where maximum wins can reach 10,000x to 50,000x the stake or even higher, as seen in Extra Chilli's extraordinary 50,000x maximum win potential.

The mathematical models behind BTG games demonstrate sophisticated understanding of player psychology and engagement. The varying number of Megaways, cascading reactions, and escalating multipliers create constant anticipation and genuine excitement on every spin. When you add the possibility of triggering features that can deliver wins exceeding 10,000x or even 50,000x your stake, you understand why BTG slots maintain such devoted followings among slots enthusiasts worldwide.

Licensing, Regulation, and Fair Gaming

Big Time Gaming operates under strict regulatory oversight, holding licenses from multiple respected gambling authorities. The company maintains licenses from the UK () and the Alderney Gambling Control Commission, along with authorizations in Gibraltar and Canada. These licenses ensure BTG games meet the highest standards for fairness, player protection, and responsible gaming practices.

All Big Time Gaming slots undergo rigorous third-party testing and certification, with independently verified Random Number Generators (RNGs) ensuring completely fair and unpredictable outcomes. The mathematical models, RTP percentages, and game mechanics are thoroughly audited by accredited testing laboratories, guaranteeing that the games perform exactly as advertised and cannot be manipulated.

Universal Mobile Gaming Excellence

Every Big Time Gaming slot is built using HTML5 technology, ensuring seamless compatibility across all devices and platforms. Whether you're spinning on a desktop computer, laptop, tablet, or smartphone, you'll experience identical high-quality graphics, smooth animations, and engaging sound design. The mobile experience isn't a compromised version—it's fully optimized for touchscreen controls while maintaining all features and functionality.

The games perform flawlessly on both iOS and Android devices, with no downloads or apps required—simply access them through your mobile browser and start playing immediately.

Industry Impact and Evolution Acquisition

The influence of Big Time Gaming on the modern slots industry cannot be overstated. The Megaways mechanic has spawned thousands of games from dozens of developers, fundamentally altering player expectations and industry standards. Megaways has become such a powerful draw that it's now a primary search term and marketing feature for online casinos worldwide.

In April 2021, Evolution Gaming—the world's leading live casino provider—announced the acquisition of Big Time Gaming for up to €450 million, with €220 million paid upfront (€80 million in cash and the remainder in Evolution shares) and potential earnout payments up to €230 million based on performance through 2024. The acquisition was completed in June 2021 after receiving all regulatory approvals.

This acquisition united Evolution's live casino dominance with BTG's slots innovation, creating a powerhouse combination. The deal recognized BTG's extraordinary value—in 2020, the studio generated €33 million in revenue with €29 million in EBITDA, demonstrating remarkable profitability for a relatively small development team. The acquisition ensures BTG's continued innovation while providing resources and reach to expand their influence even further.

The Future of Innovation

Big Time Gaming continues pushing boundaries with new mechanics beyond the original Megaways concept. The studio has introduced Megaclusters (cluster pays combined with cascading mechanics) and Megapays (mystery symbol mechanics), both available through their licensing program. Recent releases demonstrate ongoing creativity while maintaining the high-volatility, high-reward gameplay that defines the BTG brand.

For players seeking innovative gameplay, sophisticated mathematics, extreme volatility, and massive win potential, Big Time Gaming slots remain essential destinations. From the legendary Bonanza that started it all, to modern releases that continue evolving the Megaways formula, BTG consistently delivers experiences that keep players on the edge of their seats. Whether you're chasing that elusive 50,000x win in Extra Chilli, extending reels to 248,832 ways in White Rabbit, or exploring any of BTG's compelling catalog, you're experiencing slots from the studio that genuinely revolutionized the entire industry.
