Play Danger! High Voltage Megapays™ At These Slot Sites
About This Slot
Danger! High Voltage, released in 2017, was a slot game that helped put Big Time Gaming on the map. Blending super high variance with a trademark mix of sticky wilds, free spins and multipliers, and a classic rock-dance soundtrack from Electric Six (something else BTG do very well) it quickly became a huge hit across UK online slot sites. And remains so even now.
In August 2022, Big Time Gaming chose the game as the next to add to their growing Megapays™ series which started with Bonanza Megapays™. With four Megapays™ jackpots to play for, slots fans can now enjoy Danger! High Voltage with its super-volatile Gates of Hell and High Voltage Free Spins rounds, with the chance to win a life-changing jackpot of over £1,000,000 on top!
Who could say no to that? Here we review the game, explain the features, the maths model behind the reels and how those massive progressive jackpots can be unlocked.
RTP, Variance and Top Payout
Understanding RTP is important in progressive jackpot slots. Here, the main game RTP is 93.39%. However, an additional 9.44% goes to the progressive pool, bringing the actual RTP down to 86.59%. You will feel this in the game over a long session, but this is off set by the chance to bag a Megapays™ jackpot of course.
As we expect, the variance here is super-high, rated 5/5 by Big Time Gaming. That means long spells with little return before explosive big wins sequences (if you are lucky) mixing up those sticky wilds, multipliers and free spins. Interestingly, the hit frequency is 43.47% which implies one win in nearly every two spins.
Finally, the top payout in the main game 39,620x. This puts Danger! High Voltage above other Megapays™ games like Bonanza and The Great Pigsby, but lower than Who Wants To Be A Millionaire Megapays™ (top win, 72,310x).
Spins start at 20p per play.
Symbols and Graphics
Danger! High Voltage utilises imagery from the song lyrics on its paytable to good affect. It’s a stunning looking slot and no surprise that it helped put BTG on the map. Here are the highlights of the paytable.
- The reels set is 6 reels by 4 rows, with 4,096 paylines in play at all times. Wins are triggered by landing 3 or more identical symbols on adjacent reels, regardless of position, from left to right.
- Low payers are the cards, 9 through to Ace. 9s give you 0.1x to 0.4x for 3 to 6 on a payline. Aces give you 0.15x to 1.25x for 3 to 6 on a payline.
- The premiums are the Taco, the Disco Ball, the Gold Bell and the Day of the Dead Skull. The latter gets you 25x for six on a payline.
- In the base game, both Wilds – Wild Fire and Wild Electricity – expand to full reel height. And the Wild Electricity symbol also comes with a 6x multiplier!
- Finally, look for the My Desire Scatter which is needed to unlock free spins, in which a new Sticky Wild is active too!

Gameplay and Features
The same insane mix of free spins, huge multipliers and sticky wilds is evident in the Megapays™ version of Danger! High Voltage as you find in the original. It’s what made the game such a hit first time around. For those who need a reminder, here are those features:
Wilds and Expanding Wilds
The two wild symbols are your only enhancements in the base game. Wild Fire and Wild Electricity will both expand to full reel size, and the Wild Electricity brings a 6x multiplier to the table too.NOTE: if more than one Wild Electricity is in play and covering a win, then the multipliers are MULTIPLIED (not added). So a 3x and a 3x gets you a 9x multiplier.
Two Free Spins Rounds With 100x Multipliers
Look out for the My Desire Scatter symbols. These unlock free spins with superb win multipliers values as follows:
- 3 scatters = 6x multiplier
- 4 scatters = 20x multiplier
- 5 scatters = 50x multiplier
- 6 scatters = 100x multiplier
There is a choice of two free spins formats. You can choose either:
Gates of Hell Free Spins – get 7 free spins with one standard paytable symbol chosen as the sticky wild. It drops on reels 2 to 5 ONLY. And if you fill an entire reel with sticky wilds, you’ll be credited 3 more free spins.
Up to 19 free spins can be triggered this way … and this is where Danger! High Voltage can get really exciting … imagine 19 free spins with sticky wild reels and a 100x multiplier!
High Voltage Free Spins – this alternative free spins round has 15 free spins and a High Voltage Wild reel that can drop at any time on reels 2 to 5. This wild reel comes with a multiplier of 11x to 66x and applies to any win when the multiplier value is lit up.
During High Voltage free spins, you can earn an extra 15 free spins every time 3 scatters land. And there is no limit on the number of free spins that can be awarded.
The Megapays™ feature now gives you the chance to play for the multi-million pound Mega Jackpot. This can trigger at any time and at any stake level, though higher stakes give you higher odds of triggering the feature.
The standard reel set is removed and a Megapays™ game appears. This happens in front of a luxurious hotel setting. One low value symbols is chosen as the Megapays™ one and then the game begins.
There are FOUR jackpots available.
Your objective is to land as many Megapays™ symbols as possible. Each one that lands gets you another rung on the Megapays™ ladder. You need at least 4 to trigger a prize, and 15 to hit the Mega Jackpot. When no more Megapays™ symbols land then the round ends.
Here are the levels required to unlock each jackpot:
- Mini Jackpot (from £100) – 4 to 7 rungs on ladder
- Midi Jackpot (from £1,500) – 8 to 11 rungs on ladder
- Major Jackpot (from £20,000) – 12 to 14 rungs on ladder
- Mega Jackpot (from £300,000) – 15+ rungs on ladder
NOTE: If you land less than 4 symbols you win nothing – there are NO GUARANTEES!

Danger! High Voltage is one of the all-time great 4,096 payline slots. That magical soundtrack, disco floor backdrop and the seriously volatile reel action get the blood pumping every time. The chance to land 6 My Desire scatters and enter the free spins round with 100x multipliers is phenomenal. Our favourite of the two free spins rounds is the High Voltage format due to the higher number of plays available, and the chance to add 66x multiplier to your wins.
The only downside to this game is that spins in the base game can run for a long time with little return, which can be tough. However, keep in mind that once you get into that free spins round things heat up very quicky. And with the Megapays™ feature a possibility at all times (and at any stake level) it’s worth sticking with it if you can.
Good luck and have fun!
