BetMGM online casino and Borgata Casino are two of the most reputable gambling sites in the US, and they consistently score highly when reviewed by our experts.

In this case, we picked them because they all offer a large selection of Big Time Gaming slots, besides offering all the other major software providers. We also like their generous online casino bonuses (BetMGM even offers a $25 no-deposit casino bonus) and good terms and conditions, which give players a great experience playing Danger High Voltage slot.

Danger High Voltage slot RTP and volatility

Danger High Voltage slot has an RTP of 96.22%, which is in line with other Big Time Gaming slots. The average RTP for this software provider typically hovers between 96.20% and 96.50%. Volatility is medium to high and the highest win on a base spin will land you 10800x your stake.

Payout facts

Maximum win10800x
Highest-paying symbolDay of the Dead skull

Danger High Voltage slot machine’s medium to high volatility means bigger wins than slots like China Shores. Your biggest wins will come when the bonus features are activated, so look for the wilds. The highest-paying symbols are the expanding wilds, which can reward you with up to 15746x your stake.

70/100 Waiting for the big hit
  • Medium to high volatility
  • Max win 15746x on wilds
  • Expanding wilds
  • Low RTP
  • No jackpot

If there’s one thing that slots like NetEnt’s classic Gonzo’s Quest have taught me, this is that I should always give a game with a lower RTP a chance. There’s a lot more to the world of online slots than the payout percentage – or so everyone keeps telling me.

Me, I’m a bit more difficult to convince. This is one of the reasons I’m not that into BTG slots – the RTP is always mediocre. Seriously, what’s up with that! Not gonna lie, knowing that they make a habit of this approach doesn’t make me look at them favorably. I mean, I know I can simply head over to something like Bloodsuckers slot and enjoy an instant extra 2% chance of winning. So what’s to stop me from doing exactly that?

I’ll tell you what. The volatility. Wins may be infrequent, but truth be said the max base payouts for Danger High Voltage slot machine aren’t too bad, and I’m enough of a sucker to be reeled in waiting for the next big hit.

Danger High Voltage game stake limits

Danger High Voltage slot machine has six reels and four rows which offers you 4,096 ways to win starting with a min bet of 0.2 and a max bet of 40. That translates into anything from very low-level bets of $0.20 to high-stake $40 per spin.

Danger High Voltage slot comes with the option of setting loss limits and single win limits for those players who want to keep a close eye on their bankroll. The maximum win on a base spin is $102,400.

Stake limits rating

70/100 Low entry stakes
  • 4,096 paylines
  • Low minimum stake
  • Not much going on for high-rollers

I quite like the fact that the betting range is quite generous, following the lead of similar games like Butterfly Staxx slot. Most of us will only ever play at the shallow end of the $0.20 stake. But given that this can potentially lead a max win of $512 in cash, it makes me feel that even on a low bankroll I can get my payday. To be fair, I didn’t once land the maximum win on a minimum stake, but it’s hope that keeps me spinning. 

Every time I played Danger High Voltage slot machine I counted a win with every three spins, give or take. Just enough to keep me interested without turning it into a snoozefest. But for me the slot’s attraction doesn’t like in the base stakes and payout but in its many features.

Danger High Voltage slot bonus features

Danger High Voltage slot machine has rolled out the red carpet of bonuses. The game comes with two free spins features, multipliers and sticky wilds and all of these can increase the payout big time.

Considering the lack of jackpot, Danger High Voltage slot still has the capability of wreaking havoc with its bonus features, which can increase the max win from 10800x your stake to 15746x.

  • Frequent free spins
  • Respins
  • High paying wilds
  • No jackpot

Aha, now we’re talking baby. I forget technicalities like RTP% very fast when presented with Danger High Voltage slot machine’s fun bonus features. Let me get straight to the point – BTG are on fire with this one. 

Where do I start? The two different Danger High Voltage free spins are as good a place as any. I get free spins when I land sticky wilds, and more free spins with High Voltage wild reels. This is a trademark move on the part of Big Time Gaming. Some of their other slots, like Bonanza Megaways, also have two different free spin options. It’s a trademark that gets my full approval. By the way, the free spins can be retriggered for a potentially endless stream of free spins. What’s not to like? The free spins features are where I can really max out my wins if I get lucky, so the damn right I’m getting excited about them.

My second favorite feature of this game is the Wild Electricity Feature, because it leads to x6 multipliers. Maybe not a stellar push, but one that can make a real difference if your stake is on the higher side. When playing for real money, I’d opt for PayPal, because I’d want the withdrawal speed on my side when stacking up Wild Electricity wins.

Bonus features

Wild Fire

When the Wild Fire wild symbol appears, it covers all four positions of the reel, replacing all the other symbols but the scatter symbol. The Wild Fire symbol can land on reels two to five.

Wild Electricity

Similar to the previous wild, it also covers all four positions of the reel, replacing all the other symbols except the scatter symbol. It also multiplies your win by 6x.

Sticky Wild

This Wild symbol only appears in the Gates of Hell Free Spins. A sticky wild substitutes all symbols during the free spin; it stays in its position until the spins round is finished.

Gates of Hell Free Spins

This is the first of the two free spins features in the Danger High Voltage game. It offers you seven free spins. This one is activated when you succeed in landing three or more scatter symbols at any place on the slot. With this free spins round, you are awarded three new spins whenever all 4 positions on a reel are covered in sticky wilds.

High Voltage Free Spins

When you choose the High Voltage free spins, you get 15 free spins. This free spin has the potential of multiplying your wins on the side by 11x and 66x. The wild symbols can appear on reels two to five. This Danger High Voltage free spin is called such because it literally sparks up with blue lights.

Danger High Voltage audiovisuals

No prizes for guessing what the audio-visuals for Danger High Voltage slot machine are based on. The game has a disco, retro look with flashing lights serving as backdrop for the reels. The high-value symbols are the tacos, disco balls, bells and Day of the Dead skulls. The scatter is the My Desire symbol and the lower-value symbols are number and letters.

Audiovisuals facts

ThemeRock n’ Roll Disco
Sound qualityImpeccable
Mobile compatibilityNot compatible

The symbols are bright and colorful and the disco vibe is real. If it’s fun and light-hearted you’re after, it doesn’t come much better than Danger High Voltage slot. The audio is based on the song, and when you land two scatters you’ll hear the ‘fired in the disco’ lyric.

Funky soundtrack that will get you singing along, plus bright colors and disco balls make the Danger High Voltage game a winner in terms of audiovisuals.

Audiovisuals rating

90/100 Take me to the dancefloor
  • Cool visuals
  • Upbeat theme music
  • Other songs included
  • You might end up buying an Electric 6 album

Look here, I won’t beat around the bush. I’m a sucker for a good, trashy, early-noughties indie anthem. So of course, Danger High Voltage slot machine’s audiovisuals are putting a huge grin on my face. I almost put on the Electric 6 original while playing this but guess what – I didn’t even need it. Because the audio totally brings it, and I want that emotional high of having the lyrics complement my spinning reels. 

Thank you, Big Time Gaming. You gave me a piece of my youth back while indulging me in one of my favorite pastimes. All else is forgiven. 

Danger High Voltage game layout

Six reels, four rows and 4,096 ways to win. Wins are awarded when you land adjacent symbols from left to right beginning from reel 1. The only exception is the scatter, which can land anywhere.

Layout facts

Reel layoutEg: 5×3
Turbo modeNo
Ease of useVery easy
Game historyYes

Danger High Voltage slot comes with an autoplay function that can be set between five and 100 spins. If you’re the wary sort, you can also set a limit to your losses. Useful for when you’re skimming towards the end of your bankroll.

Game layout rating

90/100 It’s my desire
  • Easy-to-use
  • Autoplay function
  • Good mobile layout
  • Max bet button not clearly marked

Ok I promise. That’s the last music pun on my side. While Danger High Voltage slot machine may not really be everything I desire in terms of layout, truth to tell it comes damn close. The design is just wacky enough to keep me entertained without interfering with the game functionality.

The control area to the right of the reels is as simple as I could ask for, with nice large buttons that do exactly what they promise. One button to set your bet value, a nice and obvious auto-spin and a manual play function. Not rocket science, but serves its purpose well, though I’d prefer it if the max bet button was a bit clearer. I also tried it on my lower-end phone (quite a small screen) and the 6×4 format adjusted beautifully, so no complaints there.

Expert verdict: would we play this slot again?

There’s fire in the gates of hell, so open up and let me in. Just in cars that wasn’t clear enough, yes. I’ll happily come back to give this game another few spins. Now, I know that I’ve been taking shots at the rather unattractive RTP% in this Danger High Voltage slot review. But even this is not enough to keep me away. 

Why? Because clearly this game was created by someone who knows how to have fun. This slot is the closest thing to a noughties disco that you’re gonna find away from the dancefloor, so I’m happy to put the volume up and spin those reels a bit more. I like the layout, I like the music, I like the colors… this slot just makes me happy.

If all this isn’t enough for you, let me remind you about the funky Danger High Voltage free spins. I’m living for that moment when the game throws the song’s iconic lyrics at me, because I know that I’m about to enter the zone of ace payouts.

  • Great mobile interface
  • Good bonus payouts
  • Funky music
  • Low RTP
  • No jackpot
