Big Time Gaming - Game Casino Software review

The developer Big Time Gaming
Logo provider Big Time Gaming

Big Time Gaming is a major innovator in online slots. Their catalogue is not as big as you’d expect, with just over 30+ games. But what they don’t have in quantity, they make up for in high quality. Bonanza won a major award for Best New Slot of 2017 and has topped the charts every year since.

After all, this is the developer that invented Megaways™ slots. And they introduce new mechanics and features regularly with releases like White Rabbit and Holy Diver.

It’s hard to believe that Big Time Gaming (BTG) was founded in 2011, less than 10 years ago. In that short time, this developer has managed to shake things up so much in the iGaming world, that their games have set new standards for their great design and innovation.

I know that I don’t even need to say it and you already know where this is going. That’s right: Megaways™!

Megaways slots have become a staple of modern mobile slots. So much so, that every other major developer has partnered with BTG to launch their own title.

Safety and regulation

Big Time Gaming’s reliability is beyond certified and guaranteed. The company holds licenses from no less than five major regulating bodies worldwide: United Kingdom Gambling Commission (UKGC), Malta Gaming Authority (MGA), Mauritius Gambling Regulatory Authority (GRA), Alderney Gambling Control Commission (AGCC), British Columbia Lottery Corporation (BCLC). This means their games are subject to rigorous testing for fairness and reliability.

Big Time Gaming slots

At first sight, BTG’s mobile slots catalogue appears limited: just over 30 slots.

That’s until you remember that many of these are among the best and post popular online casino games, beginning with their instant-classic Bonanza and big franchise hits like Monopoly Megaways™ and Who Wants To Be A Millionaire - Mystery Box™.

Bonanza won the 2017 Casinomeister Best New Slot Award.

Other major titles include The Final Countdown, Temple Quest Spinfinity and Queen of Riches.

Big Time Gaming’s slots are all developed using HTML5 technology, so they are fully mobile-optimised for iOS (iPad and iPhone) and Android devices. They can be played directly from your browser, as well as from your favourite online casino app.

Design and streaming

Design is not BTG’s strongest point. The graphics are not top-quality and the symbols tend to rely on simplistic concepts and design.

There may well be a reason for this.

Big Time Gaming’s slots are very popular among players who stream videos of their live play.

Live play streaming is also a type of publicity, and many developers try to make their games appealing to its audience. This usually means having symbols that are easy to recognise for people who aren’t experienced players. It also requires a particular kind of visual element also meant to be easily streamed.


Sadly, their games have fairly average payouts and winnings. Big Time Gaming’s slots payouts are never extremely high. As an example, Starquest can yield up to 15x your bet. And their return-to-player (RTP) rates aren’t exhilarating either, with games like Haunted House showing a miserly 91.9%.

But to be fair...

The highest-paying Big Time Gaming slots are not by the developer itself, but by other companies that partner with them to make Megaways™ titles, like iSoftBet’s Aztec Gold Megaways™.

BTG mechanics & features

By far, Big Time Gaming’s strongest point are slot mechanics.

The company made history in 2015 when it released its Megaways™ game engine. And they did it again in 2017, when they launched Bonanza. That year, the game went on to win a major award and was well on its way to becoming the classic we all know and love.

Megaways™ mechanic

Big Time Gaming’s Megaways™ mechanic consists of reels with changing numbers of rows.

This means that the number of ways to win change with every spin.

Add to this the fact that many Megaways™ slots use cascading reels, in which winning combinations explode to make way for new symbols to take their place, and the experience is just one big roller coaster of exciting possibilities.

Other features

Several recent Big Time Gaming slots introduced mechanics that are specific to those games themselves.

  • Feature Drop™: makes it possible to purchase in-game features, such as wilds, scatters and free spins. Introduced in the White Rabbit slot.
  • Reel Adventure™: mechanic where you follow the game’s character running along the bottom of the reels and triggering random features (e.g., free spins bonus round). Introduced in the 2019 Holy Diver slot.
  • Heartstopper™: enhanced free spins feature that lets you choose between two different free spins: Be My Angel or Dynamite Lover. Introduced in the Lil Devil slot.
  • TapCards™: flip cards to reveal different icons and try to match them. Can be played with a progressive jackpot . Introduced in the Starquest Tapcard™.
