Big Time Gaming, often referred to as BTG, is a leading software provider in the online casino industry. Founded in Australia, Big Time Gaming Pty has built a proven track record by developing innovative slot games that push boundaries rather than follow trends.
The studio focuses on its own games rather than mass production, which means each release feels deliberate, polished, and designed for serious slot fans. Big Time Gaming games are now featured at top online casinos worldwide, including here at 21BetsCasino.
Their slots are especially popular with players who enjoy rewarding gameplay, thanks to huge multipliers, feature drops, and some of the biggest win potential available in online slots today.
Big Time Gaming slots are not any old spin-and-go games. They are built for players who enjoy mechanics, features, and elite game play.
Megaways Mechanic – BTG’s signature feature offers up to 117,649 ways to win on a single spin. Reel sizes change every spin, keeping gameplay dynamic and unpredictable.
Free Spins Feature – Most Big Time Gaming slots include free spins rounds. These often feature increasing multipliers, wild symbols, or reel modifiers that you should know about.
Unlimited Win Multipliers – Some BTG games allow win multipliers to climb without a cap. This is where truly huge wins become possible, especially during bonus rounds.
Feature Drop & Feature Buy – Instead of traditional autoplay, many BTG slots use feature drop mechanics. This lets you activate bonus features on a single spin, often for a higher total bet.
Big Time Gaming has produced a relatively small but powerful catalogue of slot games. Every release is built to stand out.
One of the most recognisable Megaways slots ever created. Bonanza Megaways combines the classic board game theme with six reels, massive ways to win, feature drops, and huge multipliers.
A modern Megaways classic that focuses on feature drop options, single spin bonuses, and max megaways potential. It is fast-paced and ideal for players who like control over volatility.
Sink your teeth into this slot, it’s a 6 reel game that offers up to 4096 ways to win. Plus you can’t beat win exchange features and bonus buy.
This Halloween themed slot is one of Big Time Gaming’s best. With a max win of 47,050x, a decent RTP of 96.54% and 256 ways to win – It fits perfectly into Big Time Gaming’s reputation for innovation.
It is impossible to talk about Big Time Gaming without mentioning its influence on the wider gaming industry. BTG introduced the Megaways mechanic, which completely reshaped how slot games work.
Instead of fixed paylines, Megaways slots use variable reels to create thousands of ways to win on every single spin. This innovation was later licensed to other providers, but Big Time Gaming remains the original creator and master of the mechanic.
Today, Big Time Gaming slots are considered premium content, often sitting alongside branded slots, high-volatility releases, and flagship games at top slot sites.
Big Time Gaming slots are often included in casino bonuses and active bonus offers at 21BetsCasino. Depending on the promotion, you may be able to use free spins or bonus funds on selected BTG games.
Always check wagering requirements before playing, especially with high-volatility slots. Because BTG games can produce large wins, bonus policies may include max bet limits or contribution rules.
Payment methods such as Skrill and Neteller deposits may be available, though certain bonuses may exclude specific deposit types.

Compared to studios like Pragmatic Play or traditional British casino developers, Big Time Gaming focuses less on volume and more on innovation.
You will not find hundreds of BTG slots, but every game released is designed to push mechanics forward. For players who enjoy Megaways slots, feature drops, and massive multipliers, BTG stands in a league of its own.
Big Time Gaming RTP varies by title, but most BTG slots sit around or above the 96% mark. That said, RTP alone does not tell the full story.
These games are high volatility, meaning wins can be less frequent but significantly larger. Big Time Gaming slots are built for players chasing big wins rather than steady balance growth.
Max bet levels vary by game, and some slots allow very high max cash outcomes thanks to unlimited multipliers and stacked features.
Big Time Gaming is not for everyone – and that is exactly the point. These slots are built for players who understand volatility, enjoy strategic bonus features, and chase serious win potential.
If you enjoy Megaways slots, free spins features with unlimited multipliers, and gameplay that keeps every spin exciting, Big Time Gaming delivers.
