Big Time Gaming – The Founding Fathers Of Modern Slot Mechanics

Big Time Gaming Logo

With its roots in Australia, Big Time Gaming (BTG) was founded by a team of industry veterans with the goal of shaking up the online slots scene. Launching in 2011, BTG set out to push boundaries, blend tech with entertainment, and create something that felt fresh but still instantly playable for the average slot fan.

BTG’s true breakthrough came in 2016 with the launch of Bonanza, the game that popularised its now-iconic Megaways mechanic, a dynamic reel system that changes the number of ways to win on every spin. While many providers talk about creating the next big mechanic, BTG truly put their money was their mouth is, delivering a game engine that would change the course of online slots forever.

]Players couldn’t get enough of the feeling of unpredictability and excitement that Megaways brought. The Megaways engine went on to power countless hits, both from BTG and through collaborations with other top studios, making it arguably the most influential innovation in modern slot history. For our full breakdown of Megaways slots, read our comprehensive guide here.

Megaways might be its standout creation, but BTG didn’t stop there. Who Wants To Be A Millionaire is a branded slot that captures the tension of the show with exciting gameplay, White Rabbit brought in the Extending Reels mechanic, while titles like Danger High Voltage, Lil’ Devil, and The Final Countdown gained cult status for their bold themes, huge potential, and unforgettable soundtracks.

BTG keeps its catalogue sharp by steering clear of copy-paste releases. Each slot is carefully built to offer something different, which has earned the studio a loyal fan base that knows every release is worth checking out.

What sets BTG apart is not just its fresh ideas, but how well they connect with players. Its games have always walked the line between thrilling and accessible, offering excitement without alienating casual players.

Big Time Gaming – The Fruity Slots Edit

If you’re a seasoned BTG enthusiast or looking for the best places to start, we’ve compiled our standout slots from the provider below.

Snakebite Slot
Bonanza Megaways

Big Time Gaming’s most iconic creation, Bonanza wasn’t just another slot, it was one of the early pioneers of the now-famous Megaways mechanic. This thrilling gold-mining adventure boasts engaging 3D graphics, immersive sound effects, and a genuinely exciting quest for gold that unlocks free spins with an unlimited win multiplier, potentially reaching up to 10,000x. Furthermore, Bonanza stands out with its high RTP (96%), making it not only a fan favourite but also a potentially rewarding experience for players.

Bonanza was so popular that it inspired sequels, like Bonanza Megapays, Bonanza Falls and Christmas Bonanza.

Big Time Gaming fires up the grill with Burgers, a mouth-watering follow-up to fan-favourite Donuts. This 4-reel food-themed slot serves up 256 ways to win, high volatility, and a juicy max win of 101,640x. Packed with flavour and familiar mechanics, it brings back the multiplier-filled Bonus Reels and Free Spins fans love, along with a Win Exchange feature for added spice. With bold visuals, crisp sound design, and gameplay that echoes Donuts and Chocolates, Burgers is a tasty pick for players chasing big multipliers and even bigger wins.

Danger! High Voltage

Few slots have made a mark quite like Danger! High Voltage. This 6-reel hit from Big Time Gaming delivers 4,096 ways to win, a max win of 15,746x, and a wild mix of retro visuals, tacos, and a nod to the Electric Six anthem.

Wild West-themed online slots are nothing new, yet Outlaw stood out in a crowd. Drawing clear inspiration from BTG’s cult classics Lil’ Devil and Danger! High Voltage, this slot blends familiar elements with new mechanics that keep things feeling fresh.

It’s bold, fast-paced, and not afraid to get volatile — and with a staggering max win of 64,400x your stake, Outlaw easily ranks among Big Time Gaming’s most powerful releases to date. Whether you’re in it for the high-risk bonus rounds, gritty visuals, or that signature BTG tension, Outlaw delivers a wild ride from start to finish.

BTG – Mechanics That Pack A Punch

While many studios rely on familiar formats or adopt mechanics like Megaways through licensing, Big Time Gaming stands out as the originator of some of the most influential features on online slot sites. Known for pushing boundaries and setting industry standards, BTG continues to craft in-house mechanics that blend high volatility with smart, player-focused design.

BTG’s signature mechanics appear across its portfolio and often serve as the blueprint for others to follow. Below, we’ve broken down some of the standout features you’ll find in BTG slots:

Megaways – Introduced in 2015 with Dragon Born, Megaways was a game-changer for online slots. This mechanic randomises the number of symbols per reel on each spin, allowing up to 117,649 ways to win. Instead of fixed paylines, Megaways slots feature between 2 and 7 symbols on each reel, creating a constantly shifting and dynamic experience. It wasn’t until the launch of Bonanza that the mechanic truly exploded in popularity, going on to be licensed by dozens of developers and becoming a defining feature in modern slot design.

Reel Adventure – Debuting in Holy Diver, this mechanic blends slot gameplay with progression-based elements. As players spin, they help a character journey through a level-based map, unlocking loot chests and bonus features along the way.

Win Exchange – As seen in games like Max Megaways, this mechanic gives players the option to trade moderate wins for a shot at triggering the bonus round. For example, if a player wins 100x or more, they can choose to enter the Free Spins directly instead of collecting the win.

Dual Reaction – Found in games like Extra Chilli, this mechanic is tied to cascading reels. After a win, the winning symbols disappear and new ones fall into place from above. This cascade includes the horizontal row of symbols above the middle reels. This increases the chance of chaining wins and hitting those all-important bonus symbols.

Extended Reels – Showcased in White Rabbit, this mechanic increases reel height during free spins. Each reel can expand from the standard 5 symbols up to 12, drastically increasing the number of potential Megaways and boosting win potential. Combined with feature retriggers and multipliers, this mechanic pushes slot volatility to new heights.

Big Time Gaming – Our Verdict

Big Time Gaming remains a powerhouse in the slot industry. While it’s best known for its game-changing Megaways mechanic, it offers so much more. With innovations like cascading reels in Danger! High Voltage and expanding reels in White Rabbit, BTG continues to push the boundaries of slot design.

What sets them apart is their ability to stay true to their vision while evolving with fresh features and bold gameplay. BTG doesn’t follow trends – they set them. Their slots consistently captivate players, offering high volatility, massive win potential, and unique twists that keep things exciting.

Even as new studios rise, Big Time Gaming’s legacy as a creative and industry-leading provider is secure, and they continue to keep us on our toes with every release.
