Big Time Gaming RTP & Volatility Profile
Big Time Gaming has a reputation for developing high-volatility slots. This means that wins are not that frequent, but when luck smiles upon you, the rewards are generally high. The high-risk, high-reward setup makes their slots particularly appealing to experienced slot lovers who enjoy an adrenaline rush and don’t mind a few dry spells along the way.
The average Big Time Gaming RTP is between 95% and 96%, with it varying depending on the online casino. Many BTG titles also feature bonus buy mechanics, letting you buy your way into free spins or other exciting features. While this can speed up big wins, it also increases exposure to losses, so it’s a tool best used wisely.
Innovative Features & Mechanics
Big Time Gaming is constantly innovating to ensure each spin remains as exciting as the last. Below, I have highlighted the key features that make the best Big Time Gaming slots stick out like the proverbial sore thumb.
- Megaways: A dynamic reels system that offers thousands of ways to win.
- Megaclusters: With each winning combo, the symbols divide into four, increasing the grid and your chances of winning.
- Bonus Buy: Buy access to a slot’s bonus features. It’s expensive, so use it sparingly.
- Cascading Reels: Winning symbols disappear and are replaced with new ones. This allows multiple wins per spin.
- Expanding Symbols: Symbols grow to cover more of the reel to allow for bigger wins.
- Multiplier Ladders: A multiplier that increases with every consecutive win.
- Feature Gambles: Risk your winnings for a chance to earn more. You might need to guess the Suit or Color of a card or play a Higher/Lower game.
What is the Megaways Mechanic?
BTG Megaways is a reel system that transformed how modern slots work. Instead of there being fixed paylines, random reel modifiers are used, which means the number of symbols on the reels changes with every spin. This creates a staggering 117,649 ways to win.
With Big Time Gaming Megaways, wins are usually followed by cascading mechanics. If you have been paying attention, you’ll already know what this means. If not, like a disappointed father, I’m not going to repeat myself. Also, during bonus rounds, increasing multipliers can boost consecutive wins, dramatically raising payout potential.
What really helped reshape the slot industry was BTG’s licensing model. They licensed Megaways to other top software developers like Blueprint, Red Tiger, and Pragmatic Play, allowing them to also develop slots with this mechanic. As a result, Megaways is now a genre of its own.
Megaways became so popular that BTG started licensing the mechanic to other studios, so you'll see "Megaways" slots from dozens of different providers, all paying homage (and royalties) to BTG's original invention.
Partnerships & Megaways Licensing
As we already know, BTG didn’t just invent Megaways, it turned it into a staple of the iGaming industry. Instead of keeping the mechanic for themselves, BTG allowed other developers to use it in their own slots. Blueprint Gaming, Pragmatic Play, and Red Tiger have taken full advantage of this kindness.
Big Time Gaming’s willingness to share has helped the Megaways mechanic spread and reach slot lovers in regulated markets worldwide. Also, thanks to strict licensing requirements, these games are required to meet high regulatory and compliance standards. As a result, you can be certain that the slots you are spinning are secure and fair.
The advantages of Megaways licensing are clear: this fun mechanic is now available in loads of different themes and volatility. Being part of the Evolution ecosystem means any future innovations from BGT will have plenty of reach and influence.
Awards & Industry Recognition
When you single-handedly help shape the iGaming industry, plenty of rewards are likely to come your way. BTG has picked up numerous accolades over the years, and below are some of the most impressive ones.
- Casinomeister Awards: Bonanza named Best iGaming Software Experience (2017)
- EGR B2B Awards: Innovation in RNG Casino Software for the Megaways mechanic (2018)
- Global Gaming Awards: Digital Product of the Year (2020)
- GAM3 Awards: Big Time wins Game of the Year (2022)
If they keep on at the rate they’re going, I feel like they might need to get themselves a bigger trophy room.
Conclusion
BTG’s legacy is defined by its relentless innovation and its ability to change how people think about slots. Their famous Megaways mechanic helped to bring about a new category of high-volatility slots that deliver plenty of excitement and much winning potential.
Big Time Gaming’s reputation for developing thrilling, high-risk slots was strengthened by standout titles such as Bonanza Megaways, Extra Chilli Megaways, and White Rabbit Megaways. These slots push the boundaries with their dynamic reels, cascading wins, and expanding symbols. If you want to see whether they are truly worth the hype, I recommend testing the games in demo mode before spending real money.
This software developer has earned a strong reputation by constantly delivering innovative mechanics and memorable games that appeal to players and operators. Their titles are available in regulated markets worldwide, and earlier I highlighted the best platforms to play Big Time Gaming inventions.
I've had more than my fair share of spins on their titles. There have been plenty of happiness, groans, and sessions that have stretched way past my bedtime. Yet, I always come back for more, drawn in by the inventiveness and unpredictable thrills that only BGT can deliver.
