Max Megaways By The Numbers

• RTP: 96.64%
• Variance: High
• Top Win: 147,620 x
• Reels: 6
• Rows: Up to 7
• Paylines: Up to 117,649
• Release Date: July 2023

Less than a year after the release of Max Megaways, Big Time Gaming launched Max Megaways 2. The familiar theme music and reel layout return from the popular original title, but the location has moved. No longer taking place in an evil villain’s underground lair, this highly volatile sequel is set in outer space.

Since the reel setup is identical to the original, there’s still a maximum possible 117,649 ways to win. However, the RTP of 96.65% is slightly bigger than its predecessor, as is the maximum possible win of 147,620x. Not only is this figure an improvement on the original, it actually catapults Max Megaways 2 straight to the top of the BTG max payout chart.

The game’s features remain largely the same, with a few minor tweaks. Gone is the Wild Bomb, for instance, replaced by Symbol To Wild. Here, a symbol is randomly selected, and if any matches appear on reels 2 through 6, they’re replaced to create wins. Both games are fun to play, leaning more towards the Austin Powers vibe than James Bond.

Max Megaways By The Numbers

• RTP: 96.37%
• Variance: High
• Top Win: 139,200 x
• Reels: 6
• Rows: Up to 7
• Paylines: Up to 117,649
• Release Date: September 2022

Launched in September 2022, Max Megaways is an innovative, action-packed, spy-themed slot. The layout hosts 6 reels, with anywhere from two to seven symbols on each row. Plus there’s an extra horizontal reel above columns 2, 3, 4 and 5. 

Max Megaways is highly volatile, with a solid 96.37% RTP and up to 117,649 ways to win. You’ll encounter colourful gems, a couple of triggering scatters, regular wilds and wild bombs on the reels. Betting options are on the low side, with minimum stakes starting at £0.20 and rising to just £20.00 per play. 

However, the potential to win big comes from the game’s free spins round, where a 139,200x max win is up for grabs. Look out too for double multipliers, duplicating wilds, scatter retriggers and increased ways to win. During the base game, any prize of at least 100x can be exchanged for 10 free spins.

Wild Flower By The Numbers

• RTP: 96.52%
• Variance: High
• Top Win: 114,100x
• Reels: 6
• Rows: 4
• Paylines: 4,096
• Release Date: April 2021

Break the curse of eternal frost in this highly volatile slot. Released in April 2022, Wild Flower features 6 reels with up to 4,096 ways to win. Another game suitable for lower-staking players, its betting options range from £0.10 to £20 per play. Further, the game’s RTP of 96.52% is more than reasonable. 

Reminiscent of Little Red Riding Hood, the biggest rewards come from a mystical purple wolf and a red-cloaked lady. And like older BTG releases The Final Countdown and Lil’ Devil, there are familiar features such as full reel wilds. Wild Ice and Wild Flowers only land on reels 2 to 5, but substitute for regular symbols. What’s more, you’ll receive 8x the payout whenever Wild Flowers create a win.

Triggering either free spins bonus puts you in line for the 114,100x max payout. The first awards seven free spins and sticky wilds, with 12 free spins and multipliers of up to 80x in the second. However, trigger enhanced mode and you could bank multipliers of up to 800x!

Lil Devil By The Numbers

• RTP: 96.43%
• Variance: High
• Top Win: 50,000x
• Reels: 6
• Rows: 4
• Paylines: 4,096
• Release Date: September 2019

This highly volatile slot is a September 2019 release. Pitting good against evil, Lil’ Devil has an edgy feel and plays out on a 6×4 setup with 4,096 possible ways to win. The game’s RTP is decent at 96.31%, while betting begins at £0.10 per spin.

Purple hearts, fiery scorpions, lizards in a jar and smiling alligators all feature on the reels, along with Devil and Angel wilds. The latter will land with multipliers ranging from 4x to 12x, meaning up to 144x should two appear.

Hit two scatters to gain a heart, collecting 40 in total to trigger the highly rewarding Heartstopper Enhanced Free Spins game. However, three scatters is enough to trigger a standard free spins round, where you can choose one of two options. Whether you opt for the Be My Angel or Dynamite Lover free spins game all depends on your mood. Are you feeling naughty or nice?

Wheel of Fortune Megaways By The Numbers

• RTP: 96.46%
• Variance: High
• Top Win: 80,150x
• Reels: 6
• Rows: Up to 10
• Paylines: Up to 1,000,000
• Release Date: February 2021

Flash cars, speedboats and diamond rings are among the glitzy and glamorous symbols to grace the Wheel of Fortune Megaways reels. Released in January 2021, the stakes range from £0.20 to a whopping £500 maximum bet. This highly volatile game offers up to 117,649 ways to win, with a solid 96.46% RTP. 

Spin the wheel of fortune to reveal the starting number of ways to win. Every time an Expansion symbol lands, the reels swell to a maximum of 10, similar to the likes of White Rabbit. Hit the maximum number of symbols for retriggers, where the wheel spins again, awarding up to 12 additional plays. 

If spins retrigger, wilds can transform into mega stacks of 10. And with extending reels, the number of ways to win grows to a massive 1,000,000. Naturally, this offers the best chance of hitting that 80,000x maximum payout.

Rasputin Megaways By The Numbers

• RTP: 96.68%
• Variance: High
• Top Win: 68,180x
• Reels: 6
• Rows: 2 or more
• Paylines: Up to 2,985,984
• Release Date: December 2022

In Rasputin Megaways, you’ll spin six reels to the sounds of Boney M’s disco classic. Launched in December 2022, this highly volatile slot features an array of what looks like priceless Faberge eggs in purple, red, blue and green.

With a relatively high RTP of 96.68% and bets ranging from £0.10 to £20, Rasputin Megaways provides up to 1,000,000 ways to win in the base game. However, trigger the free spins with extending reels for an incredible 2,985,984 ways and a shot at the 68,180x top payout. Ra, ra, massive win!

Rasputin wilds can grow reels up to 10 symbols in the base game, and 12 symbols high during free spins. In fact, there are two different free spins modes to explore. One offers unlimited multipliers, with the other providing extra free spins every time a reel extends.

Pop By The Numbers

• RTP: 96.54%
• Variance: High
• Top Win: 66,960x
• Reels: 4
• Rows: 4
• Paylines: 256
• Release Date: March 2021

In this March 2021 release, it’s time to have some fun at the amusement arcades on the pier. Pop features a slightly unusual 4×4 slot grid, with a decent 96.54% RTP and 256 potential ways to win. Bets start as low as £0.10 per play, with an upper stake of £20. 

This highly volatile game is the third in a series of slots which began with Donuts, followed by the sequel Chocolates. It features a collection of balloons, in addition to the standard playing card icons on the reels. Wilds land with multiplier values of up to 4x in the base game. Three scatters will trigger 12 free spins, where each position has a persistent multiplier attached. 

Following every win involving balloons or wilds, the multipliers involved increase. It’s also possible to retrigger free spins during this bonus game, which gives you the best shot at hitting the 66,960x maximum win.

Chocolates By The Numbers

• RTP: 96.6%
• Variance: High
• Top Win: 65,536x
• Reels: 4
• Rows: 4
• Paylines: Up to 65,536
• Release Date: January 2022

Released in October 2020, Chocolates is a 4-reel slot featuring luxury chocs wrapped in purple, red, blue and green foil. Another highly volatile game, this one boasts 2,401 ways to win in the base game. However, during the free spins feature, this can spike to 65,536. 

The second title in the aforementioned series, the game’s RTP of 96.60% is fairly similar to the subsequent release, Pop. Betting limits are identical, and the maximum possible payout is only marginally less. You can spin the reels from anywhere between £0.10 and £20, just like other slots in the collection. 

Golden Ticket wilds don’t just substitute to create new wins, but multiply such payouts by 6x. But the keys to success here are the clock scatter and the yellow chocolate boxes. The former award up to 10 free spins and make all chocolate boxes sticky. In turn, these boxes reveal up to four rewarding chocolate symbols.

Outlaw By The Numbers

• RTP: 96.1%
• Variance: High
• Top Win: 64,400x
• Reels: 6
• Rows: Up to 7
• Paylines: Up to 117,649
• Release Date: November 2022

Head to the wild west for a classic showdown in BTG’s Outlaw. As you might expect, it’s also a highly volatile game, with a respectable 96.10% RTP. The 6-reel slot setup also features rows with varying numbers of symbols, ranging from two to seven. This provides up to 117,649 ways to win.

Outlaw first appeared in November 2022. Its higher-paying symbols include a purple skull, red flower, blue bottle and green cactus. Further, there are two full reel wilds that substitute for regular symbols, a Wild Outlaw and a Wild Sheriff. Find the latter to secure a 7x win multiplier. Scatters trigger the free spins bonus, where you’ll select one of two options. 

The first game, Fallen Angel, awards 7 free spins and sticky wilds. Dizzy in the Head offers 8 free spins with multipliers up to 77x and retriggers. For the best shot at nabbing the 64,400x maximum win though, trigger the Enhanced Free Spins game with a Megascatter. Here you’ll receive either a transforming sticky wild or up to 777x win multipliers.

Beef Lightning By The Numbers

• RTP: 96.43%
• Variance: High
• Top Win: 56,000x
• Reels: 6
• Rows: Up To 7
• Paylines: Up to 117,649
• Release Date: June 2021

The Beef Lightning playing grid is located on a cartoon farm. Six reels hold up to seven symbols at a time, supplying as many as 117,649 potential ways to win. Launched in June 2021, the slot initially won fans with its pleasing graphics, solid 96.43% RTP, fun bonus feature and 56,000x maximum win.

The game’s star quality is undoubtedly the unique free spins game. Landing three MOO scatters awards 12 free spins, with a further four available per extra scatter. Duplicating wilds can occur at random, replacing all of the symbols found on the reel with wilds. All fairly standard so far, but here’s where the fun begins.

This game is a cattle auction, where you start the round with one cow and no bids. At the end of the free spins period, the number of cows is multiplied by the final bid. This figure is awarded as your prize. The Bonus symbol can also appear during free spins. It can reveal an auction bid, an increased number of cows, a retrigger or cash prize up to 2,500x. 

King of Cats Megaways By The Numbers

• RTP: 96.72%
• Variance: High
• Top Win:  56,620x
• Reels: 6
• Rows: Up to 7
• Paylines: Up to 117,649
• Release Date: May 2021

Switch between the African Savanna and the jungles of darkest Peru in this May 2021 release. Featuring the highly innovative Playerselect mechanic, King of Cats Megaways effectively provides players with two entirely different base games. It’s up to you whether you spin the Lion or the Puma.

The slot is highly volatile, with six reels and up to 117,649 ways to win, plus an RTP of 96.70%. As with so many of these BTG titles, your best chance of triggering the 56,000x max win comes in the free spins round. Scatters in either game trigger up to 20 Lion free spins or 24 Puma free spins. 

Every time a Lion or Puma wild lands, the multipliers on that reel will increase. Playing the Lion Game activates 2×2, 3×3 and 4×4 wilds, with multipliers reaching 16x. However, in the Puma Game, there are as many as three full reel Puma wilds, with multipliers up to 4x.

So, how can we be sure that BTG slots are capable or producing these massive payouts?

For the UK market, under the watchful eye of the UK Gambling Commission, the integrity of Random Number Generator (RNG) software that is integral to the game engines, and maximum win values, is always verified by approved third-party auditors like eCorga, prior to release. As part of the process, millions of spins are simulated. These spins are also used to verify the Return to Player (RTP) value of all slots.

So, yes, you really can win that much and it has been proved in tests. But you should also bear in mind that the odds of hitting those max payouts are outrageous – in the millions to 1 every time. And on top of that, these are also highly volatile games and the win patterns are very irregular, so expect a rough ride. No one said it would be easy to score a 100,00ox win!

Compared to other industry leading providers, Big Time Gaming is up there with the best. For instance, Max Megaways, with its huge 139,200x potential payout, follows in the footsteps of Pragmatic Play’s Peking Luck (180,000x) and Push Gaming’s Razor Returns (100,000x). We have profiled the top paying games from both these studios in further articles. Check out Pragmatic Play’s highest paying slots here, and Push Gaming’s best payers here.

Of course, all of these are a long way off catching Nolimit City’s incredible Tombstone RIP, which boasts a top payout of 300,000x. You can read our run down of NLC’s highest paying games here.

Big Time Gaming’s rapid ascent to the highest ranks of slots developers over the past decade has come from dedication to innovative design. The company’s trademarked Megaways game engine is the best example of that and it has changed the face of slots gameplay forever. But, as you can tell from our list, it is by mixing thrilling features with excellent potential, that BTG has become the number one studio of choice for so many slots enthusiasts.
