Big Time Gaming Slots & Online Casinos

Big Time Gaming, also known as BTG, is one of the rare providers that can boast international success thanks to innovative and original payout systems that enable players to walk away with huge prizes.

In fact, one of their innovations has its own dedicated category in online casinos. It’s called Megaways. Players in US casinos, both sweepstakes and online casinos, can choose from dozens of titles under the famed trademark label.

Our guide on Big Time Gaming slots and casinos will point you to some of the best online casino games that you can play to win cash prizes. With plenty of deposit bonuses to choose from, your adventure on the best BTG slots can start right here.

Legal & Safe Big Time Gaming Casinos in the US

BTG holds four government-issued licenses from European authorities which lend the provider the credibility that is recognized by international players.

A good share of Megaways games are available in US casinos and gambling sites, thanks to licensing that is extended by Evolution Gaming. The latter is an important player in the iGaming world who purchased Big Time Gaming in 2021.

Evolution has been present in US online casinos through its partnership with land casinos since 2019. These credentials make BTG part of a limited range of truly international software providers whose unique features and payout mechanics can be experienced at US casinos. Currently, NJ, PA, MI, WV, CT, and DE allow online casinos, so if you are based there you can hop on the Megaways bandwagon. Elsewhere, you can try sweepstakes casino Megaways slots.

With licenses being acquired in multiple US states and games that are independently audited, we can say that BTG via Evolution is a sure-shot developer of slots that offers some of the biggest win maximums in the world.

Big Time Gaming Slots and Games Features

Golden Nugget Megaways Slots

Big Time Gaming was founded in 2011 but released its first game in 2014. We can’t say for sure why all the waiting, but we have one solid guess: Its team has been working on something big since day one – the Megaways. Indeed this is the main landmark but it isn’t the only thing that makes BTG slots stand apart from the competition.


The company’s first release, Lucky Streak, contains BTG’s signature dab on the graphic design that you see throughout its catalog. Make no mistake, every single game that gets released is as original as they get, yet there is a common visual element that binds them all under the same logo. The graphics are only the start.

Cascading Megaways

Paired with lots of moving parts on the reels and rows, the mechanic of choice for BTG is cascading wins. As a matter of fact, it is impossible to imagine a Megaways game without subsequent wins arising from the same spin. This permits win multipliers to add up or cross-multiply, depending on the game.

Big Win Maximums

As for the Megaways mechanic itself, sure you’ll find it licensed out on more than a hundred online slots out there, however, BTG is the originator and its native games are the archetypal host. Which speaks for another common feature of this company and its famed payout system: big win maximums. Choose any Megaways game and you’ll be playing for a chance to hit at least 10,000x your bet.

Megaclusters, Megaquads, Megapays

Well now you know BTG’s favorite word. If not sure, it’s Mega! All of these are signature mechanics that are imbued with an algorithmic potential to trigger nosebleed sequences leading to insane winnings. The last one, Megapays, is just another word for progressive jackpots.

7 Best Big Time Gaming Online Slots

With a reputation for action-packed slots games, there’s no shortage of Big Time Gaming slots to recommend. There are 39 Megaways slots available at US online casinos, with the Megaways functionality one of the main draws. We’ve narrowed down the field to bring you our top 7 games you should take for a spin.

  1. Bonanza
  2. Wheel of Fortune Megaways
  3. Extra Chilli
  4. Kingmaker Megaways
  5. Danger High Voltage
  6. Gonzo’s Quest Megaways
  7. Monopoly Megaways


Bonanza Slot

This is the second Megaways title in the history of the “genre”. The premise is a bucolic mining town from a low-tech era where you’ll be in the company of gold bullions, dynamite Wilds and precious gems.

Bonanza embodies all of the usual components of Megaways slots: high volatility engine, 96% RTP, max Megaways potential and $0.20 spin minimum. The reason for Bonanza’s popularity is because Big Time Gaming has created one of the most interesting probability engines.

The game is famous for its rising win multipliers that don’t reset. Getting a winning streak to start early in the bonus game is your key to the big loot. Landing huge wins isn’t unheard of on Bonanza, but to get near the max 26,000x bet you’ll need several retriggering events.

Bonanza is available on BetMGM alongside 30 other Megaways games. You can claim a competitive welcome bonus to start playing today.

Wheel of Fortune Megaways

Wheel of Fortune Megaways Slot

It is safe to say that Wheel Of Fortune is the epitome of US game show culture and the show’s whimsy for prizes is deserving of a slot game. The “problem” is, there are close to a dozen Wheel of Fortune slots. The solution: there is only one WOF Megaways slot and its single-spin winning cap is 80,150x your bet.

Like all true Megaways slots, the layout has six reels that can host 117,649 possible win combinations. The volatility level is expectedly high and the RTP is a solid 96.46%. Its top bonus feature is a free spins bonus that comes with a twist – you get to spin the Wheel of Fortune to determine the number of guaranteed win-ways for the duration of the free rounds.

If the wedge stops on the max Megaways field, you’ll be in for a crazy ride on a layout of six reels and at least seven rows. So, the maximum win combination will expand likewise, to up to 1,000,000.

Wheel of Fortune Megaways is part of the exclusive Wheel of Fortune Casino, alongside several other BTG titles.

Extra Chilli

Extra Chilli Slot

Extra Chilli is another BTG game that ranks high on international best slots lists. Players will find sparking stained glass chillies on a six-reel layout that can bring out the best of its high volatility engine. RTP is another solid entry for the BTG catalog, with 96.82%. $0.20 per spin minimum lets you let the game in cruise control and discover its whims.

Players should pace their bets for the lowbrow moments of the highly volatile engine. Winning outcomes come at a smaller frequency but the balancing act comes in the shape of lucrative win cascades.

One approach to playing Extra Chilli Megaways is to switch up your bets on intervals in order to maintain your bankroll afloat. The idea is to make it to the free spins bonus or wait for a discount bonus buy on the Feature Drop display, as the prices can change between each spin.

Overall, BTG has created a well-rounded game with a 20,000x bet win potential which you can play at Borgata Online.

Kingmaker Megaways

Kingmaker Megaways Slot

Kingmaker is one of the rare Megaways slots by BTG that doesn’t offer the full 117,649 win-ways. The game at hand can go up to 16,807 combinations, but that doesn’t make it any less fun or lucrative.

You can win up to 10,000x your stake during the free spins bonus but the big win potential is also there in base game. The element that defines Kingmaker Megaways are the so-called Gem Multipliers.

You’ll notice there is a dedicated meter for each of the high-paying symbols. This is the multiplier value, which goes up by +1 for every combination of five or more gems of the same kind. The value of the multiplier stays locked until you trigger the free spins bonus.

Don’t worry about the reset as there is a kicker. Before the free rounds begin, all of the multiplier values are added together and remain in play. This figure gets higher by landing additional sets of five gems.

Kingmaker Megaways is available at another BTG casino: Golden Nugget, where you can play this and other games in demo mode for free.

Danger High Voltage

Danger High Voltage Slot

Big Time Gaming can master other payout mechanics too. This is the first game on our list of top BTG slots that does mighty fine without the Megaways system. Danger High Voltage has gained a cult-like following due to more than one reason, that is, feature.

First off, the highest multiplier value can reach 86x your win and there are two full Wild reel possibilities with a default multiplier of 6x. From the get-go of every Wild reel win, each combination gets its multiplied individually.

Unfortunately, BTG Megaways slots don’t offer the free spins bonuses that Danger High Voltage does. You can choose to play 7 FS with sticky wilds or 15 FS with Wild reels that can set random multipliers between 11x and 66x.

The game at hand packs heat for specs: 15,746x max wins; 95.67% RTP and 4096 win-ways. Wandering already which bonus to claim in order to play? 888 Casino US has Danger High Voltage – just use the search button to look it up.

Gonzo’s Quest Megaways

Gonzo's Quest Megaways Slot

If you are a slots pro please don’t be a snob. We know this is not a BTG release, but it is powered by BTG’s Megaways so we’ll put it on the list. Just because Gonzo’s Quest is such a classic. But this game, it blows to pieces the former’s max win with 21,000x your stake.

Gonzo’s Quest Megaways was released by Red Tiger with a medium to high volatility engine and average RTP value of 94.66%. The best features from the original games are still available – the cascading wins mechanic and win multipliers that can reach 5x for the fifth cascade in the base game and 15x during the free spins bonus.

What’s more, the game has Wilds that don’t disappear following a winning cascade. In fact, they remain in the game for as long as there are other cascades. Another kicker is the Earthquake modifier in the bonus game: it destroys all low-paying tiles. And it all clicks together marvelously under the Megaways system.

If you are ready to join Gonzo on his Quest you can turn to BetRivers, another excellent US online casino.

Monopoly Megaways

Monopoly Megaways Slot

We are wrapping up our top 7 BTG slots with the best board game ever that’s been rendered through the Megaways system. Again, BTG is treating distinguishing players to industry-solid RTP of 96.50%, but on the other hand of the equation is a highly volatile engine which justifies a max win potential of 14,700x.

The thrill of playing Monopoly is in the board-game nature of this Megaways slot. Each cascading win makes the Monopoly man move a number of fields. Properties can be owned, houses and hotels built – all automated by the impeccable random number generator.

Utility and railroad cards are collected, the GO field awards you with guaranteed 117,649 win-ways for that spin, and the Chance and Community cards also add their own positive twist to the game. Who needs a FS bonus when the base game can be so much fun, right?

Well, BTG did add bonus spins where your win multiplier can increase for each house that you own across the board. Further, train stations add free spins and Utilities add multipliers. It really is a game of Monopoly where you can win real big cash.

One of the venues where you can play Monopoly Megaways is DraftKings Casino.

Highest RTP Slot Games by Big Time Gaming

Each bet accounts for 100% against the average RTP%. Return to Player is an estimate for what percentage of all bets the player can win over a longer period of time. The remainder is the house edge which is required by casinos to be able to provide their services. If there is a big win, the RTP percentage is blown off so the player makes more money on that spin. In other words, your winning outcomes can vary and are always random.

Another metric is volatility which helps set your expectations. Low volatility slots award smaller prizes but at a greater frequency. Highly volatile slots can take you through dry spells while leaving room for massive payouts. BTG casino games are known to be highly volatile with huge payout potential.

Although there are never guarantees with slot machines, it doesn’t hurt knowing the best paying BTG slots in the US:

Big Time Gaming Company Information & Background

Big Time Gaming Story

BTG had its launch in 2011 in New South Wales, Australia where its headquarters remain to this day. The company is run by a core team consisting of five people, led by CEO Nik Robinson. We can safely assume that Nik and team did 110% on every release to earn BTG international recognition.

The company released its first Megaways game (Dragon Born) in 2015. Word of the upgraded mechanic spread like a hot rumor and five years later, BTG released more than 15 games, proving Megaways isn’t just a fad. Danger High Voltage and Bonanza were awarded Best iGaming Experience in 2017, among other highlights for the company.

All of this earned Big Time Gaming the attention of bigger fish in the game. In 2021, Evolution Gaming acquired BTG and by doing so, it paved the way for Megaways slots entering the US. Big Time Gaming had acquired the most important operating licenses even before the purchase. The company is licensed by:

  • United Kingdom Gambling Commission
  • Malta Gaming Authority
  • Alderney Gambling Control Commission

However, thanks to the Evolution purchase, BTG slots appear in the best online casinos in the US, owing to their being licensed by the following state bodies:

  • State of Connecticut Department of Consumer Protection
  • New Jersey Division of Gaming Enforcement
  • Pennsylvania Gaming Control Board
  • Michigan Gaming Control Board
  • West Virginia State Lottery

BTG’s catalog isn’t huge. The company prefers having a quality over quantity approach, so when a new slot game is announced, everybody is paying attention – both the players and the casinos.

In summary, we can expect even more Big Time Gaming titles to appear across online and sweepstakes casinos in the US in the near future.
