Big Time Gaming is an Australian casino software developer founded in 2011. The company is based in Sydney.
I first noticed Big Time Gaming when a lot of slot Twitch streamers and Youtubers talked about and played BTG’s slot Danger High Voltage. Also my friend seemed to like this slot game a lot. Danger High Voltage has a reputation of a game where you can win big time.

This is Big Time Gaming’s hit slot: Danger High Voltage. It is a mixture of everything and the result is a bit crazy.
Big Time Gaming has also acquired a lot of licenses to create slot games of famous TV shows and franchises. The selection has slot games of names like Who wants to be a Millionaire or Monopoly Megaways.
So Big Time Gaming seems to have the ability to create slot game hits. Let’s find about more about BTG’s slot games!
Big Time Gaming Slot Game Features
Here are some features of Big Time Gaming slot games.
- Megaways (TM) slots bring a huge number of different ways to win. If you want to know more about Megaways, scroll down a little to the slot Who Wants To Be a Millionaire review where it is explained more closely.
- Other Big Time Gaming’s Megaways slots are for example: Bonanza, Extra Chilli, Dragon Horn, Vikings Unleashed, Queen of Riches, Genie Jackpots, Temple Tumble, Diamond Mine and Irish Riches.
- Some older slots are running with Adobe Flash “technology” which is not the best in security and needs clumsy drivers to be downloaded. Avoid these slots if they ask to install Flash, rather pick some other.
- In general all the games have great quality in animations and graphics. Also most of the games have at least a decent soundtrack. The game mechanics in many BTG’s games is interesting with a lot of features in the bonus games.
New Big Time Gaming Slots
Here are some of the newest Big Time Gaming slot games.
1. Who wants to be a Millionaire Megaways
Who wants to be a Millionaire Megaways is a quite new slot game released at the end of 2018 with the official theme of the famous TV-quiz. The slot is basically a six reel with Big Time Gaming’s unique Megaways structure.
The symbols are also reactive or collapsing. This means that the winning lines disappear and more symbols drop from the top of the reels. This can trigger more wins.
The extra reel adds a symbol to the reels 2 – 5.

Who Wants To Be a Millionaire slot is really true to the original TV show with great graphics, animations and of course – the original theme music!

An explanation what the Megaways (TM) means. Basically you just have to have the same symbol starting from the left to right on adjacent reels. The symbol position on the reel doesn’t matter. This creates a lot of ways to win, 117 649 on this slot to be specific. This number comes from 7 x 7 x 7 x 7 x 7 x 7 = 117 649 as each reel can have up to 7 symbols on this slot.
Wild symbols substitute all symbols except Scatter. Wilds are only present in the extra reel.
The Millionaire Scatter symbol can appear in any of the six regular reels. If you get 3 Scatter symbols, you win 8 Free Spins and start the Hot Seat Free Spins Gamble bonus game.
Each additional Scatter above 3 Scatters will move you up a rung in the Hot Seat prize ladder. The Free Spin Scatter symbol can appear in the extra reel during Free Spins.
If you get 3 or 4 Scatters in the bonus game to the bonus reel, you will be granted 4 or 8 extra Free Spins respectively.
The Hot Seat Free Spins Gamble gives you the chance to win up to 50 Free Spins. The gamble prize ladder has 12 steps. The values are 8, 10, 12, 14, 16, 18, 20, 22, 25, 30, 40 and 50 Free Spins depending on the step.

This is how the Hot Seat Free Spins Gamble looks like. You have to choose how high up on the ladder you dare to go. The Lifelines come automatically into the play.
If you got the Hot Seat with 3 Scatters, you will start at Step 1. If you got 4 Scatters, you will start on Step 2 and so on.
Steps 2 and 7 are safety net steps. Reaching these rungs guarantee at least 10 and 20 Free Spins respectively.
Walk Away feature: To start Free Spins without gambling press Walk Away. To gamble, select an answer from A, B, C or D and press Final Answer. A successful gamble moves you up in the steps of the prize ladder. You cannot Walk Away from step 2 and 7, because these are risk free and safe gambles.
Like in the real Who wants to be a Millionaire TV show you also have Lifelines. These come automatically into play to make your choice easier.
During the Free Spins there is an unlimited win multiplier which starts at 1 and is increased by 1 after each win.

This is the Bonus Game of Who Wants To Be a Millionaire slot. Each win will increase the win multiplier by 1, now being x2 in the test game.
In conclusion the slot Who Wants To Be a Millionaire was a big surprise. The TV show spirit has been captured perfectly to the slot and the only thing is missing is the TV host. The music, graphics and animations are really high quality and well made.
Also the game mechanic is interesting with Big Time Gaming’s special Megaways. And the bonus game rounds are also true to the original TV show with climbing the ladders like in the real Hot Seat.
This is just an awesome slot with no flaws in my opinion.

Most Popular Big Time Gaming Slots
Here are some of the most popular Big Time Gaming slots introduced.
1. Danger High Voltage
Big Time Gaming’s Danger High Voltage is somewhat of a slot legend. Many slot streamers in Twitch or tubers in Youtube play this game a lot. The reason might be that Danger High Voltage has a high variance and you can win extremely high winnings from the bonus game or full reel wilds from this slot.

The gameplay of Danger High Voltage slot from Big Time Gaming.
The theme of the game is a bit unclear for me. The name of the slot comes from the song Danger! High Voltage from the band Electric Six.
(Check the song here from Youtube if you like. Here’s some more info about the band from Wikipedia. The song is from 2003 and is a combination of garage, disco and punk rock. Funny song nevertheless!)
So there is a garage rock song involved in the slot. But there is also some Mexican style slot symbols with a little of the Day of the Dead style with decorated and colorful skulls. And tacos?! And Tattoos, Disco Balls symbols and disco lights?!
And the High Voltage tells that there is some electricity and lightning somewhere. So I am totally confused with the theme…but maybe that is the key to this slot’s success! Nobody knows what it is about, but it can give you huge wins if you are lucky. And it is fun to play. Maybe that’s just enough for a great slot!
Something about the slot game mechanics here. Wild Fire is a full reel wild symbol that substitutes all symbols except Scatter.
Wild Electricity is also a full reel wild symbol that works the same way, but all wins are multiplied by 6 for every Wild Electricity substitutes in the win. If you get 2 Wild Electricity symbols, the multiplication happens two times and is x36. This is a quite great feature.

Here you can see the two different Wild Reels: Wild Electricity on the left and Wild Fire on the right. The Wild Electricity gives you x6 the winnings for every substitute in the win. You can also get multiple x6 Wilds.
Both of these Wild symbols occur on reels 2 to 5 only.
Three or more Scatter symbols (The tattoo symbols with My Desire text) triggers the Bonus Game. Also the 2 Scatters and the bonus game will trigger the slot’s theme song: Danger! High Voltage. The Bonus game enables a choice between two features.
- Choice 1 – High Voltage Free Spins. This option awards you 15 Free Spins plus full reel High Voltage Wilds that can pay up to x66 on adjacent wins. The 15 free spins can be re-triggered with three or more Scatters. Wild multiplies all pays except Scatter.
- Choice 2 – Gates of Hell Free Spins. This bonus game gets you 7 Free Spins. A random symbol is selected to become a Sticky Wild for the duration of the bonus on reels 2, 3, 4 and 5. Four Sticky Wilds in a reel awards 3 extra Free Spins up to a total of 19 Free Spins.

Here are the two choices of the Bonus Game in Danger High Voltage.
In my tests you can really see that the variance of this slot is set to very high. The bonus games were really hard to get, but the bonus games gave a lot when I hit them. The first bonus game (High Voltage Free Spins) gave a prize of x144 times my bet.

Here is the Bonus Game called High Voltage Free Spins with the spinning High Voltage Wild with up to x66 multiplication.
Hitting the second bonus game took some time, but that time I chose the Gates of Hell Free Spins. The total win was x87 this time. I found the first bonus game (High Voltage Free Spins) a bit more fun with the changing wild reel that can pay up to x66 the winning line.

This is the second bonus game Gates of Hell Free Spins. In this game a random symbol is selected for a Sticky Wild. Here I got the 9’s as Sticky Wilds, already 3 in the game.
After my testing I now understand why Danger High Voltage slot is so popular slot game. It hasn’t got the best graphics, animations or sounds. It feels quite a mess of many ideas and themes mixed together, but the whole package just works.
There is some mysterious charm or magic in Danger High Voltage. You can somehow feel the “danger” of big wins with really high variance. If you don’t believe, go and test for yourself with real or play money. In overall, I really liked this slot!

2. Bonanza
Big Time Gaming’s Bonanza is a gold rush themed slot with the Megaways slot feature like the Millionaire-slot.
The slot features 6 reels which each can have from 2 to 7 symbols. There is also a bonus reel in the top (the Carts) that add up symbols to reels 2 – 5.

This is the gold rush themed Bonanza slot from Big Time Gaming.
The Wild symbol substitute every symbol except Scatter. The Wilds are only present in the extra reel (the Carts above).
The Scatter symbols can appear in any of the reels. If you get four GOLD Scatters you win 12 Free Spins in the bonus game. Any extra Scatter adds 5 Free Spins to the bonus game.

G-O-L is not enough for the bonus game, you need the D!
In the Bonus Game, 3 Scatters will get you 5 extra Free Spins and 4 Scatters 10 extra Free Spins. The Scatters only appear in the bonus reel (the Carts above).

Bonanza bonus game looks like this.
During the bonus game, after each win on the reels the multiplier increases by 1.

Every win in the bonus game will increase the multiplier, here x3.
In conclusion Bonanza was quite interesting slot game with the cool Megaways reel structure. The bonus game was quite basic with just free spins and the increasing multiplier, but that was ok too. The bonus game was really hard to get this time which can relate to the high variance of the slot.
The graphics and animations are on a very high level like on all Big Time Gaming slots. The country style music started to get a little annoying at the end of the testing, but maybe that’s a matter of taste. Bonanza is a really cool slot worth trying out.
Game released: December 2016
RTP (Return to player): 95.98 %
Variance: High
Layout: 6 x 7 + Extra reel
Betting lines: 117 649 (Megaways)
3. Extra Chilli
Extra Chilli is a Mexican themed chilli-slot game established in April 2018. The graphics are very colorful and the background music is happy trumpet-rich Mexican Mariachi type music.
This game also features the Big Time Gaming’s famous Megaways game mechanics with 117 649 betways. So there are 6 reels with 2 – 7 symbols on each reel. Plus there is also a bonus reel under reels 2 – 5.

This is Big Time Gaming’s Extra Chilli slot game. With the Scatter symbols H-O-T you can trigger the Free Spins Bonus Game.
The symbol structure is “collapsing” which means that after each win, the winning symbols disappear and more symbols will drop from the above. This can trigger more wins in the reels.
Wild symbols substitute all symbols except Scatters and Feature Drop symbols. Wilds are only present in the extra reel under reels 2 – 5.
If you get 3 HOT Scatters in any position, you will trigger 8 Free Spins. Any extra Scatter symbol will add an extra 4 Free Spins.
In the Bonus Game you will be taken to Free Spins Gamble. In this feature, you have a chance to win up to 24 Free Spins. You can choose either to Collect or Gamble.

In the Bonus Game you can gamble for more free spins. This is the first round: you can either Collect the 8 free spins. Or you can Gamble for 12 or zero free spins. Mathematically the best choice in the long term is always to Collect the 8 Free Spins. But this is gambling, so I totally understand if you try to hunt for the 24 Free Spins!

Here I managed to hit the maximum 24 Free Spins in the Bonus Game Gamble. Not recommended however! In the long term it’s always best to stick to the 8 Free Spins in this slot game.
If you Collect, the free spins will start right away. If you Gamble, there is a spin of the wheel. A successful gamble will award you 4 extra Free Spins. An unsuccessful gamble awards the number of Free Spins displayed in black. If the number is in black, the feature ends.
In the Bonus Game Free Spins there is an unlimited multiplier which starts at 1 and is increased after each win on the reels.

The Bonus Game multiplier is indeed unlimited! Here I managed to get x19 multiplier in my testing.
Free Spin Scatter symbol can appear in the extra reel and trigger more free spins. With 3 Scatters you will get 4 extra free spins and with 4 Scattters 8 extra free spins.
With the Feature Drop you can buy the bonus games that start instantly. The price of a bonus game is 50x the bet. A small feature is if you get BTG (Big Time Gaming) symbols. They will decrease the Feature Drop prize with small increments.
In conclusion Extra Chilli is a really fun slot game with happy atmosphere. The RTP (Return to Player) percentage is also quite high with 96.82 %, which is always a good thing for players.
Game released: April 2018
