History & Company Background

Big Time Gaming, headquartered in Sydney, Australia, has established itself in the upper echelons of the iGaming industry thanks to the creation of iconic slots and, more specifically, game-changing mechanics. No one could argue against BTG’s Megaways altering the face of the slots industry, with the studio consistently bringing new ideas to the table, whether it be through advanced gaming engines, tweaking existing in-play dynamics, or exciting features that have the potential to transform a base game or bonus round into thrilling gameplay.

Nik Robinson, the CEO and founder of Big Time Gaming, can take huge credit for pushing the boundaries of online slot gaming. He founded the company in 2011 and guided it to the very top of the industry, which in 2021 saw the company bought out by market leader Evolution. Currently, it seems as though little has changed since the acquisition, with it being business as usual regarding the content being released.

Only time will tell Whether we will be treated to more new and innovative gaming engines like Megaclusters and Megapays. But, if history has taught us one thing so far, it’s that BTG is always ahead of the game regarding online slot creation, and now they are powered by evolution, too; we could see something in the future that would eclipse Megaways’ success, which indeed would be something to shout about.

Global Presence

Since its inception, the team at Big Time Gaming has worked hard to expand its footprint across iGaming jurisdictions around the world. The success of Megaways has helped in this regard, gaining the studio increased exposure by putting it in the spotlight in many key markets. A recent example is BTG’s push into North America, with Megaways proving just as popular in Canada and US states like Delaware and New Jersey as they have elsewhere. 

BTG’s games are available in online casinos across Europe and the UK, and now, with Evolution’s backing, the brand is pushing further into North American markets. As for future plans, CEO Nik Robinson is on record saying that a move into LatAm markets, particularly Brazil, is in their sights.

Highest RTP Big Time Gaming Slots

You do have to give Big Time Gaming some kudos, as they are one of the few slot studios that have stuck to just one RTP model of their games, unlike other providers who offer multiple levels of RTP to online casinos. What does this leave us with? An entire catalogue of slots with some of the industry’s most impressive return to player percentages. If this is a significant factor for you when deciding which slots you’d like to play, use our data table to find the best offerings within the BTG portfolio.

Big Time Gaming Product Portfolio

BTG’s primary focus has always been to create online slots featuring cutting-edge and engaging mechanics primarily developed in-house. You’ll not find virtual, live table, or any other type of casino game in their portfolio. The only exception would be a handful of progressive jackpot slots – which you’ll learn about later in this review. 

Online Slot Games

Compared to other studios, you’d hardly class Big Time Gaming as prolific, considering their portfolio only contains 80+ slots, with half featuring the Megaways mechanic. That said, the slow and steady approach is one we admire at Demoslot, and it is probably a significant factor in why the studio has released so many popular titles. 

We’ve listed a few of those slots below, and if any catch your eye, why not read more about them and try a free demo?

  • Bonanza: If there’s one slot that solidified BTG’s place at the top, it’s Bonanza Megaways. While it wasn’t the first to introduce the Megaways mechanic, it was the first featuring it to really catch people’s attention. Offering up to 117,649 ways to win coupled with cascading reels and a free spins bonus with an unlimited win multiplier, Bonanza remains one of the best Megaways slots around. 

  • Extra Chilli Megaways: A spicy follow-up to Bonanza, this title ramped up the intensity and added a free spins gamble feature. The slot’s high volatility, electrifying soundtrack, and massive win potential have kept Extra Chilli Megaways relevant even now. 

  • Rasputin Megaways: The reason Rasputin Megaways shocked the slots sphere? It was the first slot to give players the potential to spin with up to 1 million ways to win. BTG, as always, thinks big, and this slot, with its high volatility and those potential winways, has gone on to become a bigger classic than most. 

  • Danger High Voltage: Before Megaways, BTG was already making waves with releases like Danger High Voltage. Known for its quirky theme and explosive gameplay, DHV features expanding wild reels, sticky wilds, and a 66x multiplier that can trigger some shocking wins. Even without the Megaways mechanic, this game remains a classic in the BTG catalogue.

  • Holy Diver Megaways: The music-themed Holy Diver Megaways stands out for blending BTG’s Megaways mechanic with a unique Reel Adventure™ system. Set in a medieval world with knights and mythical creatures, the slot features up to 586,971 ways to win, expanding wilds, multipliers, and a free spins bonus you’re given the choice to trigger or upgrade.

Game Mechanics & How They Work

If there’s one thing we can say about Big Time Gaming, it’s that they love to innovate. We all know that no other mechanic has taken the slot space by storm nearly as much as Megaways”, but BTG hasn’t stopped there. The software provider has also given us the MegaPays Jackpots mechanic, Megacluseters”, Megaquads”, and more recently, MegaDozer”. 

Megaways

It goes without saying that we’ll start with Big Time Gaming’s jewel in the crown. Of course, that’s the Megaways mechanic that propelled Big Time Gaming to the top table in the iGaming industry and simultaneously revolutionised the slot gaming landscape.   

Equally as genius as creating the mechanic in the first place was the decision to lease it out to other online software developers. While BTG is responsible for over 40 releases containing Megaways, another 500+ have come from those who have leased it, including Blueprint Gaming, Relax Gaming, BGaming, and Red Tiger Gaming.

As for the engine, it is a random reel modifier that allows for a random number (usually between 2 and 7) of symbols to appear on each slot reel. Combinations are created when matching symbols line up across successive reels, eliminating the need for paylines. Depending on the slot, the mechanic can produce spins with up to 117,649 or even as many as millions of ways to win. 

Some of Big Time Gaming’s Best Megaways slots;

  • Bonanza (Up to 117,649 Ways to Win)
  • Extra Chilli (Up to 117,649 Ways to Win)
  • Golden Catch (Up to 117,649 Ways to Win)
  • Gold Megaways (Up to 1 Million Ways to Win in the Bonus Game)
  • Rasputin Megaways (Up to 2,985,984 Ways to Win)

Megaclusters

It can be challenging trying to follow up on the monumental success of something like Megaways, but trailblazers as they are, BTG, have come up with several other mechanics over the years. One is MegaClusters, which offers a twist on the regular cluster pays mechanic developed by NetEnt. Making its debut on the Star Cluster Megaclusters in 2020, it works by splitting up each winning symbol in a cluster into four smaller random symbols.

The studio has released a handful of Megacluster slots, with the best of them listed below:

  • Star Clusters Megaclusters
  • Millionaire Rush Megaclusters
  • Cyberslot Megaclusters
  • Diamond Fruits Megaclusters
  • Vegas Rush

Megaquads

Another mechanic that Big Time Gaming debuted in 2021 is Megaquads, which again has struggled to replicate the success of Megaways. Whether it catches on or not, it’s undoubtedly dynamic, as it involves players spinning four individual sets of reels that can merge during bonus features to offer a staggering 16,777,216 ways to win. 

The mechanic has been used in two slots to date, with those listed below:

  • Slot Vegas Megaquads
  • Slot Vegas Fully Loaded Megaquads

Megapays

If you’ve come across our Megapays page here at Demoslot, you’ll probably know that MegaPays is Big Time Gaming’s answer to progressive jackpot networks from other developers. Many of you will have seen the likes of Blueprint Gaming’s Jackpot King, Relax Gaming’s Dream Drop, and, of course, the big two, the Mega Mollah and WowPot from Microgaming. 

BTG designed the network, which contains four (Mini, Midi, Major, and Mega) progressive jackpots for implementation on select Megaways slots. The RTP on these versions of the slots would take a hit due to the chance of winning 6-7 figure sums when playing, but ultimately, players can choose to play the regular version or one that contributes to the Megapays jackpot pool.  

The Jackpot game can trigger on any spin, and which of the four you win will come down to how many instances of a randomly selected symbol appear as a result of a Jackpot spin. Those lucky enough to win the Mega will scoop a minimum of €300,000, but up to millions depending on how long the jackpot has continued to grow without being won.  

The four BTG MegaPays slots currently available are: 

  • Bonanza MegaPays
  • Danger High Voltage MegaPays
  • Star Clusters MegaPays
  • Who Wants to be a Millionaire? MegaPays

Megadozer

The most recent Big Time Gaming creation is still in its infancy, with MegaDozer featured on just two slots. The mechanic debuted in the Bonanza Falls release at the end of 2023, a slot developed in collaboration with Light & Wonder, and in Danger High Voltage 2 in 2024.

MegaDozer takes inspiration from the coin-pusher games you’ll come across in arcades. For instance, in Bonanza Falls, as you spin, more coins drop into the chamber above the reels, and the Dozer will continue to push them until the coins drop into the reels to reveal bonus features and modifiers.  

Expect future BTG releases to feature this mechanic, with demos available right here at Demoslot.

Our Conclusion:

Danger High Voltage is still very much one of our favourite online slots. The two bonus rounds bring their own levels of excitement to the table, and the base game has massive potential by being able to roll in three x6 wild multipliers for an epic win that can eclipse anything either of the features is capable of.

Slot Stats: RTP: 96.00% | Max Win: 10000x | Review & Demo

Our Conclusion: Bonanza Megaways is quite possibly the best online slot ever to be created. Not only was it the first of its kind in the Megaways series, but it would go on to inspire hundreds of new games that featured the combo of an unlimited win multiplier and cascading reels.Such was the success of Bonanza that Big Time Gaming even added their Megapays Jackpot Engine to it, so players could enjoy all the thrills they had experienced before, but with Bonanza Megapays, they now had the chance to win a life-changing amount of money too.To conclude, Bonanza Megaways is rated so highly at Demoslot that it is currently the only slot ever to receive the MAX WIN rating and a perfect score of 10. Simply put, this is a sensational slot that every player must try at least once.;

Commitment to Player Safety & Fariness

Licensing & Regulation

It stands to reason that Big Time Gaming, particularly now that it’s part of the Evolution group, has earned the licenses necessary to operate in some of the world’s key iGaming markets. 

Partnerships & Collaborations

Big Time Gaming has formed countless partnerships over the years, but some stand out more than others for various reasons. One mutually beneficial cooperation was formed in 2018 when BTG joined forces with Relax Gaming. Relax Gaming distributed Big Time’s slots across major European iGaming markets, and in return, the studio gained initial intellectual property rights to BTG’s infamous Megaways mechanic. In the same year, Blueprint Gaming became the first to lease the mechanic and remains one of the most prolific Megaways slot creators, with others since following suit, such as iSoftBet, Pragmatic Play, and IGT, among those that have secured leases for the mechanic.  

The most significant collaboration to date, however, is Evolution’s €450 acquisition. Joining a group that already includes Red Tiger Gaming and NetEnt, with Nolimit City added more recently, marked one of the biggest deals in iGaming history and was a major milestone in BTG’s history. 

Spin Gifts

All bundled under the same Evolution umbrella, a partnership between Big Time Gaming, NetEnt, Red Tiger, and Nolimit City was always likely to happen, and it has. The quartet have collaborated to create the Spin Gifts promotion, which rewards players with up to 100 free spins when playing selected titles from the studios. 

Final Summary

Thanks to the revolutionary Megaways mechanic, Big Time Gaming has been rubbing shoulders with game providers at the top table since around 2018. Now, with Evolution backing them, the studio is perfectly positioned to continue breaking new ground in slot development. Will we ever get anything as game-changing as Megaways again? Only time will tell, but it’s sure to be exciting following their journey. Be sure to check back here regularly to discover and play all of BTG’s latest releases!
