Slot Bonanza by BTG

Released in December 2016, the online slot “Bonanza” quickly gained traction in the casino community. What sets it apart? Its innovative Megaways game engine. This engine features six reels, each displaying up to seven symbols, offering a dynamic range of 64 to 117,649 potential winning combinations.

The number of ways to win varies with each spin, thanks to a system that randomly selects between two to seven symbols for each reel.

When you score a win, the winning symbols explode, allowing new ones to fall into place. If these new symbols form another win, the process repeats—continuing until no further wins are formed.

The real allure of Bonanza lies in its free spins round. Activate it by landing 4 scatters that spell “GOLD” in a single spin. This grants you 12 free spins, with each additional scatter adding 5 more. As an added twist, an unlimited multiplier increases by 1x after every win during these spins.

The game’s unique mechanics, especially the elusive “D” in “GOLD,” have sparked considerable chatter and memes in online casino player furums like Casinomeister.com.

About Big Time Gaming in Brief

Big Time Gaming (BTG) is an Australian-based online casino content creator that started in 2011. While it might seem smaller when compared to industry giants like Microgaming, NetEnt, and Play’n Go, there’s no denying BTG’s profound impact on the iGaming scene. Their groundbreaking Megaways mechanic—introduced in 2016—changed the way we experience online slots.

Big Time Gaming (BTG)

This innovation, combined with their distinctive range of online slots, has carved a niche for BTG in the iGaming world. Their commitment to quality and continuous innovation has made them a standout in the iGaming industry. This was further highlighted when Evolution Gaming acquired BTG in 2021.

  • Megaways Mechanic

    Launched in 2016, this feature acts as a random reel modifier, changing the number of symbols on each reel during spins. This offers players a myriad of winning ways, ranging from hundreds to hundreds of thousands. Due to its impact, BTG started licensing this mechanic to other casino game software developers in 2018.

  • Team and Leadership

    BTG’s rise isn’t by chance. Spearheaded by industry stalwarts like CEO Nik Robinson—with over a quarter-century in the iGaming sector—BTG’s foundation is solid. Robinson’s past endeavors include pioneering browser-based online gambling solutions and developing the inaugural platform for real-money wagers via a Flash interface.

  • Licenses and Certifications

    With licenses from top-tier gambling regulators such as the UK Gambling Commission, the Alderney Gambling Control Commission, and the Government of Gibraltar, BTG ensures it operates within the industry’s best practices.

  • Game Features

    BTG’s slots are known for their high volatility. Take “Bonanza” for example—it promises substantial returns but demands a player’s patience. Their games generally come with a set RTP, with many hovering around the 96% mark. However, some, like “White Rabbit Megaways”, boast an RTP as high as 97.7%.

  • Innovative Mechanics

    Megaways isn’t their only innovation. In 2020, BTG rolled out the Megaclusters system. Here, when players form a winning cluster, each symbol vanishes, replaced by newer, tinier symbols, paving the way for potential additional wins.

  • Diverse Portfolio

    From the allure of ancient Egypt to the glitz of modern-day Vegas, BTG’s game themes are varied. Prioritizing quality, each game shows their dedication to creativity and innovation. Sames such as “Danger High Voltage” and “Bonanza Megaways” are testament to their appeal among online casino slot enthusiasts.

  • Future Prospects

    BTG’s method in slot game creation has earned them both a loyal fanbase and admiration from iGaming industry counterparts. Their Megaways mechanic alone has fortified their reputation as a top-tier game developer, even if their game collection might seem modest in comparison to others like Play’n GO or Pragmatic Play.

Conclusion and Final Thoughts

Big Time Gaming has certainly carved a niche for itself in the online casino world, thanks to its innovative Megaways game engine. Their slot game repertoire, though not the most expansive, is undeniably engaging. While there’s room for a broader range of games, one can’t help but applaud what they’ve achieved so far.
