    More About Big Time Gaming Slots

    BTG launched in 2011. They are based in Syndey, Australia. Founder and CEO Nik Robinson has years of experience breaking new ground in the gaming industry. In the 1990s his business, New Tech Media, was amongst the first software companies to introduce browser-based gaming and after being purchased by News Corp, merged with Orbis to become global online betting giant, OpenBet.

    So, it’s no surprise that BTG doesn’t just follow the herd when it comes to producing new slot games. Instead, their titles look to break new ground and create genuinely unique experiences. BTG are not the most prolific of studios – however, the new slots are always an instant hit in the UK – but they are becoming one of the most popular, and now with their links to the slot streaming community they have their fingers on the pulse of the industry.

    What Is Megaways™?

    The Megaways™ game engine is key to understanding what makes slot players love these games. It features five of the Big Time Gaming slots titles. It was given its first run out in the 2016 release, Dragon Born. The mechanic is based on a six-reel set-up where for every spin the size of each reel changes creating anywhere from two to seven symbols per reel.

    Winning paylines occur where identical symbols appear on adjacent reels, regardless of their position. This creates a maximum of 117,649 ways to win if all seven positions on all six reels are active for a spin (7x7x7x7x7x7).

    As you can see, even before any additional features come into play – the free spins, the multipliers, the extra bonus symbols and their functions – these games are already far more dynamic and exciting than your average 5 reel, 4 row and 20 fixed payline video slot.

    More Exciting Win Opportunities

    White Rabbit Slot by Big Time Gaming

    On top of the Megaways™ engine BTG add further features to these games to drive big, big wins if you can find a way to unlock them.

    Take the original Megaways™ game, Dragon Born, as an example. In this slot, on top of the 117,649 ways to win, you can also land Stacked Wilds on two reels simultaneously, and to add to the fun, your stacks can come with up to 7x multipliers. Where two are active, the total multiplier is calculated by multiplying those two numbers together – so where you have two wild stacks with 7x on each, your full multiplier is 49x (7×7).

    Oh – and in the bonus round you can get up to 50 free spins initially, with the opportunity for unlimited re-triggers. Wow!

    In short, the game model for Dragon Born is set up to create massive wins when all the features come together for you in the bonus round.

    The hard part of course, is getting there.

    The same can be said of the two most popular slot games built on the Megaways™ game engine, Bonanza and White Rabbit.

    In Bonanza, the big win sequences are loaded in the bonus round which itself involves a cache of at least 12 free spins which can be bumped up every time more scatters land. This is also a Rolling Reels game (also known as Avalanche or Cascading Reels)– after a winning spin, the winning symbols explode to be replaced by new ones. This continues until you land a dry spin.

    You get the picture? When you set up a bonus round with 20 or 30 free spins and rolling reels combined, you can see how things can get pretty tasty!

    Meanwhile, the Alice in Wonderland-inspired slot game, White Rabbit, features even bigger reels as its possible to extend those seven symbols right up to twelve, creating up to 248,832 ways to win (this is a 5 reel game).  But it’s the Free Spins round itself which is the highlight here, with those Expanding Reels, an Enhanced Red Queen Reel, and Bonus Wilds with Extra Multipliers.

    You can also find the Megaways™ engine and more exciting slot play on the games Queen of Riches and Starquest.


    As a variation to Megaways, BTG uses Megacluster as another unique mechanical technology to allow for big wins as opposed to using a single symbol when a winning cluster is created, Megacluster uses a bunch of matching symbols on cluster games like Star Cluster Megaclusters for example. With more symbols, Megacluster slots offer higher output and have a high RTP rate and are a popular choice amongst players.


    Yet another piece of impressive iGaming technology, BTG has created Megaquads as a way of multiplying the number of ways to win across 4 individual 4×4 grids. By triggering the Megaquads, reels connect to make 4 rows of 8 reels with 65,536 potential winning combinations.

    If that’s not enough, within the free spins feature a Rainbow Wild Bonus can be triggered summoning a new grid with 16,177,216 ways to win. Megaquads is found across a few online slot machines in Big Time Gaming Releases and is worth keeping an eye out for to make the most of the great bonus features hidden within the slot machines with this technology.

    Big Time Gaming and Slot Streaming

    BTG has positioned their games as the type of online slots that will appeal to the streaming community. Slot streamers broadcast their slot play live on sites like, allowing viewers to vicariously enjoy the thrill of a person gambling real money online, experiencing the high of a flurry of big wins on a super slot like Bonanza, whilst also learning about the game in real play mode.

    The slot streaming phenomenon is gathering pace – so much so that one of the scene’s most famous players, Kim Hultman (aka letsgiveitaspin) has partnered up with mobile casino, LeoVegas, to play exclusively through their site. And in 2017 Kim was given the world’s first spin on the new BTG game, White Rabbit, as part of the launch campaign.

    Speaking about slot streaming to the Calvin Ayre website at ICE 2018, Nik Robinson, CEO of Big Time Gaming said:

    “Twitch allows potential players to get a real emotional feel for a game without spending their hard-earned cash learning the game from scratch. Unlike demo-play, an interested punter can watch a stream and ride along with the streamer’s highs and lows; in playing the game they can then expect a similar experience”, explained Robinson.

    “Twitch streaming is live, no holds barred and a streamer is most likely to bust out on a bad run of luck. Occasionally, though, they can have a magnificent flurry of wins and build an amazing atmosphere on stream that’s shared with their viewers, akin to watching your team win a match!”

    “The fact that high volatility slots appeal to Kim and many other streamers is the reason why the majority of Twitch slot streamers play our games. There are no games in the marketplace today that can deliver wins like Megaways™ slots, which places BTG in a league of its own when it comes to sky-high volatility.”

    The next phase of this evolution is likely to be Slot Streaming Betting, where viewers of a Twitch Channel place bets on the outcome of a streamers play. That could be the next spin, or the next 100 spins. For example, a punter might bet on whether the streamer will hit a 1,000x payout any time in the next 500 spins.

    BTG Highlights

    The first real-money cluster pays game to hit the gambling market was Chain Reactors, created almost 20 years ago, the game remained extremely successful. In 2016, Megaways was demonstrated to a client in Vegas, after a few spins, the feedback was that the game, Bonanza, is too complicated and would never catch on.

    The slot was not only another first innovation in the world of online games but instantly build on the great success of the unique Megaway. patented by BTG. Bonanza Megaways™ introduced DuelReaction™, and combine two of the most popular themes, Wild West and Gold Mines. The addition of cascading symbols showed how far Big Time Gaming managed to push the boundaries.

    MegaWays™ First & Motivation Behind It

    When asked what was the motivation behind MegaWays™, Nik Robinson, Big Time Gaming’s Chief Executive Officer shared that being able to offer something fresh, surprising, entertaining and jaw-dropping is key.

    It all started with Dragon Born, the first slot to feature the unique Megaways™ system by Big Time Gaming. A unique system enabling each spin to provide up to 117,649 ways to win was about to unlock a megaways phenomenon many software developers would eagerly want to be a part of.

    A New Gaming Era

    Huge highlights included the backing of major brands and the creation of Who Wants to be a Millionaire MegaWays™ and Monopoly MegaWays™. The aim was to have more than 200 MegaWay-titles released by Big Time Gaming and its licensees, now way over 50 software developers, by the end of 2020. Many of the software providers including, Microgaming, Leander, NYX, Blueprint Gaming, iSoftBet, Red Tiger Gaming, and NetEnt, have added a variety of extra features.

    Big Time Gaming licensed MegaClusters™ next, this was after MegaWays™ proved that there are no borders when it comes to “new”. The one thing these patents ensured is that developers take innovation more seriously. Robinson feels one of the most intriguing of all is the engine used by ELK Studios for IO and Cygnus.

    Big Time Gaming – Awards Winners

    The release of White Rabbit and Bonanza in 2017 made it a ground-breaking year for BTG and their profile is now higher than ever. Indeed, for many slot players, Bonanza is one of the most exciting slot games of recent times. This was reflected in it being voted Best New Slot of 2017 in the annual Casinomesiter awards.

    BTG also took second place for Danger! High Voltage in this award.

    Casionmeister announced the award with the following comments:

    “Big Time Gaming released only three slots, a paltry amount compared to the big major developers and absolutely cleaned up the votes – in fact, they were so dominant it was nearly a whitewash for the rest.”
