Big Time Gaming is an industry leader when it comes to slot machines, as the renowned game provider hasn't stopped churning out absolute classics since it was founded and burst onto the scene back in 2011.

The company hails from Australia, and of course specializes in online slot machines, with over 80 games in its portfolio. They are also known for their Scratch Cards.

But why does Big Time Gaming stand out above the rest?

Online players primarily know of Big Time Gaming Slots for their high volatility, colorful graphics, and their high Return to Player (RTP) index. What's more, each and every game by Big Time Gaming comes with a unique theme or a angle and is accompanied by high-quality soundtracks and generous bonuses.

In this article, you can find our top five picks of the most popular slots in the Big Time Gaming catalogue.

Best Big Time Gaming Slots - At a Glance

1. Who Wants to Be a Millionaire?

The title of this Big Time Gaming Slot is just perfect for a casino game, as it's of course based on the hugely popular TV game show that goes by the same name.

The slot features both the iconic logo and the music that glued millions to the TV screen back in the day. However, nostalgia is not the only reason to play it. Here are a few more:

1. The game features a whopping 117,649 paylines.
2. The $1,000,000 jackpot can be hit at any time
3. The slot offers tumbling wins, as winning combinations explode to make new ones.

2. Bonanza

Much like Who Wants to Be a Millionaire slot, Bonanza does not offer set paylines in the traditional sense. Instead, it uses the megaways system to give you up to 117,649 ways to win with every single spin.

This Big Time Gaming slot has some great features that draw players to it time after time, most of all the scatter symbols. Hitting four of these gives players 12 free spins, and each additional scatter hit during the bonus round tops that total up by another five. 

Not only that, but the free spins come with an unlimited win multiplier, meaning players can score massive payouts from the slot. But don't just take my word for it, try it yourself!

3. Extra Chilli

Extra Chilli is a great slot for those looking to have an enjoyable user experience, as its solid graphics and vibrant theme transport you straight to the hustle and bustle of a Mexican market.

Not only that, but its RTP of 95.72% and max win of 12,000x means the game has plenty to offer beyond its theme. Be cautious when playing, however, as the slot's high volatility means wins may be fewer and farther between than other slots. 

4. Big Bass Vegas Double Down Deluxe

Do you enjoy slots featuring the bright lights of Vegas? How about the classic fishing variety that we now see so often? Well look no further for a combination of the two, as Big Bass Vegas Double Down Deluxe does what it says on the tin: doubles down.

The slot is slightly more relaxing for players in terms of swings, as this one features medium volatility, rather than the high volatility that is so prevalent across Big Time Gaming slots.

The slot is packed with features, including but not limited to wild symbols, scatter symbols, multipliers, as well as free spins. Each feature serves a specific purpose and can significantly boost your potential winnings.

5. Danger High Voltage

Anybody familiar with the song by Electric Six will know exactly what to expect from a slot that has been inspired by it: adrenaline-packed funk.

Danger High Voltage whisks players away to a neon world, filled with disco balls and upbeat music. If the gameplay somehow isn't enough to entice you, surely its in-game features will be:

1. The game features a huge 4,096 ways to win.
2. Scatter symbols can trigger a bonus game at any time.
3. The High Voltage and Gates of Hell bonuses can make for big instant wins.

Big Time Gaming is one of the biggest names in online slots for a reason: time after time they knock it out of the park with their games, each of which is seemingly better than the last.

Their trademark high volatility offers the chance for huge wins, and their adoption of the megaways system into their slots, again, gives players more and more ways to win every time.

Top 5 Highest RTP Slots from Big Time Gaming 

Although the main goal of most slot providers it to create elegant, detailed games with intricate features and unique dynamics, that's often not the key factor that draws people in. Now matter how fun the game might be to play, the RTP (return to player) undoubtedly takes precedent.

Big Time Gaming repeatedly produces slots that feature a high RTP that's above the industry standard. Across their large array of slots, the return to player is often very high and even reaches the heights of 97% in some cases. This is not all that common for online slots, and goes to show that Big Time Gaming have earned their reputation.

Here's a quick overview of the highest RTP slots from the provider. 

White Rabbit Megaways - Big Time Gaming's Highest RTP Slot (97.72%) 

White Rabbit Megaways isn't just any slot. The Alice in Wonderland theme transports you to the magical world created by Lewis Carroll, and that isn't even the best part.

The 97.72% RTP offered by the slot isn't just Big Time Gaming's highest, but it's one of the highest among any game on the market. Of course, with any casino game you play, you will on average lose money over time - otherwise casinos wouldn't be in business! But a high RTP like this means those losses should theoretically be lower in the long run. 

As for the gameplay, there are the classic 5 reels that spin, however slightly more than the 20 paylines that was the industry standard for so long. The game, as is in the name, adopts the Megaways feature, meaning that each spin has a dynamic number of paylines, which can be up to a whopping 248,832, which is even more than the average Megaways slot!

The game also features plenty of bonus features, including wild symbols, scatters, and free spins once a bonus game has been triggered.

For its RTP alone, it's worth trying out White Rabbit Megaways, but its other features ensure it's not just another generic classic slot, and a max win of 13,000x doesn't go unnoticed.
