About provider


If you've ever spun a slot with 100,000+ ways to win, there's a good chance Big Time Gaming (a.k.a. BTG) built the engine under the hood.
Founded in Australia, in 2011, BTG spent its early years building a solid reputation before dropping one of the most influential slot mechanics in the history, which is, Megaways. That single invention turned a small Australian studio into one of the most talked-about names in the industry.
Their breakout moment came in 2016 with Bonanza Megaways, a gold-rush themed slot with dynamic reels and up to 117,649 ways to win per spin. The player response was so strong that BTG licensed the mechanic out to other studios. Blueprint Gaming became the first to lease the mechanic, and others like iSoftBet, Pragmatic Play, and IGT have since followed.
In 2021, Big Time Gaming was acquired by Evolution Gaming for approximately €450 million. This brought the studio under the same roof as NetEnt, Red Tiger Gaming, and Nolimit City.

Big Time Gaming Products

BTG keeps a tight catalog. As of recent years, the studio has around 80 slot games, which is a fraction of what larger studios produce. That's a deliberate choice. BTG bets on quality and innovation over volume, and it shows in the mechanics packed into every release.

Video Slots

These make up the bulk of their catalog. These are not your classic three-reel machines. BTG slots tend to run on one of their proprietary engines, with dynamic reels, cascading wins, and bonus features that can stack multipliers into the thousands. Examples include Bonanza Megaways, White Rabbit, and Big Bad Bison.

Scratch Cards

Scratch cards are part of the portfolio too, offering quick, low-commitment play for people who want instant action without sitting through spin cycles.

Arcade Games

Arcade Games are round things out for players who want something a little different from traditional slots.
Fun fact: Bonanza Megaways became so popular after its 2016 launch that it essentially created its own slot genre. Over 50 other developers now license the Megaways mechanic from BTG.

Big Time Gaming Special Features

BTG's biggest contribution to the industry isn't any single game. It's the suite of mechanics they've built and licensed out. In this section, we will see what makes their games tick.

Megaways

Megaways is the big one. This feature changes the number of symbols on each reel with every spin, meaning the number of ways to win is different on every single round, adding a layer of unpredictability you don't get with standard paylines.
At its peak, Megaways games offer up to 117,649 ways to win. You can see it in action in Bonanza Megaways and Big Bad Bison, among many others.

Megaclusters

Megaclusters takes the cluster pays format and pushes it further. When a win happens, each symbol breaks into smaller icons, which then react. Winning icons disappear and new ones drop in from the top. Star Clusters Megaclusters was the game that introduced this mechanic to the world.

Megapays

Megapays adds a progressive jackpot layer to select titles. The feature triggers randomly on any spin. Getting at least one Megapays symbol triggers a respin, and landing four or more makes you eligible to win one of the progressive jackpots. The jackpot tiers go Mini, Midi, Major, and Mega. You can find this mechanic in games like Danger High Voltage Megapays.

Feature Drop

Feature Drop is BTG's version of a bonus buy. Rather than paying a flat fee for immediate access, the White Rabbit slot uses Feature Drop to increase the RTP from 96.24% to 97.77% and takes you directly to the free spins feature. Collect enough Feature Drop symbols during regular play and the cost goes down over time.

Win Exchange

Win Exchange gives players a choice when a decent win lands. If you win between 25x and 50x your bet, you can hold it or trade it for a shot at the free spins feature. Win 50x or more and you get guaranteed entry. This one shows up in Big Bad Bison, Max Megaways, and several others.

Megadozer

Megadozer is BTG's newest engine, that debuted in 2023 with Bonanza Falls. A dozer mechanism sits above the grid and drops silver and gold coins onto the reels after spins or reactions.

Best Big Time Gaming Games at SweepKing

In this section, we will be looking at some of the top games by BTG that are available on SweepKing. You can give these titles a try for free.

  1. Fireworks Megaways

When it comes to raw potential, nothing in BTG's catalog tops Fireworks Megaways. It holds the biggest reward of all Big Time Gaming slot games, sitting at a massive 150,335x your entry. The RTP clocks in at 96.44%, which is solid for a game with this kind of upside.
The Reaction feature pulls winning symbols off the grid so new ones can fall in, setting up chain wins that can snowball fast. If you're the type of player who chases the ceiling, this is your game. It's not for the faint-hearted, but the reward makes it worth it. Try Fireworks Megaways on SweepKing and see what all the noise is about.

  1. Big Bad Bison

Big Bad Bison brings a Native American wilderness setting to the Megaways engine, and it does it well. With six reels and up to 117,649 ways to win, the game features multiplier wilds and free spins with an unlimited win multiplier. Every retrigger during free spins increases the minimum number of Megaways and adds additional spins.
The RTP sits at 96.58% and the max win potential is 67,640x your total entry. The Win Exchange feature adds a strategic element, where you can trade it for free spins round. It's a game that rewards players who know when to take a shot. Spin Big Bad Bison on SweepKing for free today.

  1. White Rabbit

White Rabbit has held its place at the top of BTG's RTP rankings for years. With a 97.24% RTP rate, it sits among the highest RTP titles around. Plus, the Alice in Wonderland theme gives it a distinctive personality that most slots never bother trying for.
The Extending Reels mechanic is the real draw. The cupcakes appear during the bonus round and gradually expand the reels until you can have up to 248,832 ways to win.
If you care about long-term value and want a slot that gives back more than the average, White Rabbit belongs in your rotation. Play White Rabbit free on SweepKing and see the reels expand in real time.

  1. Star Clusters 2

Star Clusters 2 is the follow-up to the game that introduced Megaclusters to the world. The original broke new ground, and the sequel refines it. The first game features an above-average RTP of 96.54%, free spins triggered with five scatters, and wilds with multipliers. The sequel builds on that foundation with sharper visuals and expanded cluster mechanics.
If you've never tried a Megaclusters slot before, this series is the best introduction BTG offers. The gameplay and reward feels different here than in a standard Megaways game, and that variety is exactly what makes BTG stand out from the competition. Jump into Star Clusters 2 on SweepKing with a free demo.

  1. Bonanza Megaways

This is where it all started. Bonanza Megaways is one of the most legendary online slots ever made, carrying a 96% RTP and delivering up to 117,649 ways to win across just six reels. The mine shaft setting, the cascading wins, the free spins round with unlimited multipliers, all of it still holds up nearly a decade after launch.
The extra reel below the main six reels also features extra symbols to form more combinations, and landing HOT on that space triggers eight free spins with four more added for each additional scatter.
This is the slot that changed the industry. If you haven't played it, start here. Spin Bonanza Megaways on SweepKing and see why it's still talked about today.

Big Time Gaming Pros and Cons

In this section, we will weigh the pros and cons of Big Time Gaming to give you the complete picture.
Pros
  • Industry-leading mechanics: BTG didn't just make good slots. They invented the format that most modern high-volatility slots are built on. Megaways, Megaclusters, Megapays, and Megadozer are all original BTG creations that dozens of other studios now license.
  • Honest RTP across the board: Unlike many other providers, BTG offers only one RTP level per game regardless of where you play it. That's a commitment to transparency that not every developer makes.
  • Massive win potential: You can count the number of BTG games with maximum payouts below 10,000x on one hand. Most of their catalog falls between 10,000x and 50,000x, with Fireworks Megaways topping out at 150,335x.
  • Backed by Evolution: Since the 2021 acquisition, BTG has had the resources and distribution network of the world's largest iGaming company behind them. That means better availability across more platforms and more development firepower.
Cons
  • High volatility is not for everyone: BTG games are built for players who can handle long dry spells in exchange for big wins. These are feast-or-famine games, and that suits players who chase stories as much as payouts, but if you like steady, modest wins, most BTG titles will test your patience.
  • Bonus features steal the show: The bigger rewards are almost exclusively locked behind bonus features. If you rarely trigger the free spins round, you may not experience the full potential of a BTG game for a long time.

Final Thoughts

Big Time Gaming built a short catalog and a massive reputation. They created a mechanic that reshaped the entire slot industry, licensed it to over 50 other developers, got acquired by the biggest name in the business, and still kept putting out original ideas year after year. That track record doesn't happen by accident.
Their games are for players who want something with teeth. High volatility, big rewards, and mechanics that actually require you to think about features like Win Exchange and Feature Drop set BTG apart from slot studios that recycle the same five features across hundreds of titles.
If you’re new to BTG, start with Bonanza Megaways for the full origin story, then move to White Rabbit for the best RTP, and Fireworks Megaways when you're ready to chase the biggest number on the board. Try all three on SweepKing today, no purchase required.
