About Game

Danger High Voltage Slot

A Question Before the First Spin

Hit 3 scatters, and the Danger High Voltage slot stops to ask which round you want. High Voltage offers 15 free spins and a wild reel that multiplies an adjacent win by anything from x11 to x66. Gates of Hell runs 7 spins and turns one symbol sticky, locking it into reels 2 to 5 every time it lands. We gave a different one each time to try out both. Four wild types run through this game, and two of them turn up in normal play.

Inside The Demo

Wild Fire and Wild Electricity

Wild reels only ever land on reels 2 to 5, so reels 1 and 6 never carry one. Each type covers a reel top to bottom and substitutes for everything but the scatter.

  • Wild Fire spells its name down the reel in flames and leaves a win exactly where it found it.
  • Wild Electricity appears as as storm with a lit x6 at its foot, and the rules multiply a win by 6 for every one of them that substitutes into it.

Danger High Voltage base game with one Wild Electricity reel and two Wild Fire reels

The bar names one way at a time, so a $32.10 spin arrives in pieces. This one is $2.40, with the x6 already in it.

My Desire and the Feature Selection

The scatter is a crowned heart with My Desire inked on it, and it pays wherever it drops, with no need to start at reel 1. Land 3 and it pays 6x the stake, rising to 20x, 50x and 100x for a full 6, and whatever it pays is added to the free spins it opens.

Three or more also pause the game while you choose. Take one and the round plays itself out at the stake you triggered on.

Danger High Voltage feature choice screen, High Voltage 15 free spins with x66 wilds beside Gates of Hell 7 free spins.

High Voltage Free Spins

Pick this and 15 free spins begin with the High Voltage Wild loose on reels 2 to 5. It fills a reel like the two in normal play, but it comes with a column printed x11, x22, x33, x44, x55 and x66, one of them already lit. Every free spins win the wild touches then takes whatever is lit. Hit 3 more scatters mid-round and another 15 spins are added, with no cap on how often that can happen.

High Voltage free spins wild reel with the x44 multiplier lit, 2 free spins played and 13 remaining. x44 lit, $0.00 paid. Wins start at reel 1, so the wild only counts when reel 1 hands it something to extend.

Gates of Hell Free Spins

Seven free spins, and before a spin runs, the game reveals a symbol from the paytable at random. From then on, that symbol becomes a Sticky Wild on reels 2 to 5, takes the place of any symbol it meets, and stays where it settles. Fill one of the 4 reels with 4 sticky wilds and 3 extra spins arrive. Filling all 4 is how the round reaches the 19 spins the game advertises as its most.

Whichever symbol lands here decides the round that follows, though not by what it pays. Once it turns wild, it can complete any line, so a low symbol is no worse a draw than a top one. What counts is how often it drops, and neither screen puts a number on that.

Gates of Hell bonus reveal showing the Q chosen as the sticky wild symbol for the round. The round is chosen and locked before the game says what it is made of. Ours drew the Q.

How to Play

Demo Setup

Six reels stand 4 symbols tall, and any symbol in a column can partner any symbol in the next one, which is where 4,096 comes from. A win needs matching symbols on consecutive reels starting at reel 1, the scatter aside, and every route through them counts separately. The bar below the grid names each one as it pays.

You can play this from $0.20 a spin up to $30.00, the return is 95.67%, and volatility sits in medium-high territory with a top payout of 15,746x the stake on any one spin.

The wilds are locked out of reel 1, so a grid full of wild reels pays nothing until an ordinary symbol there gives them something to match. In High Voltage, the values are printed down the wild reel itself, so they only ever appear on reels 2 to 5.

How The Symbols Pay

Symbol 6 5 4 3 2
Sugar skull 25.00 10.00 3.75 1.25 0.50
Bell 5.00 2.50 0.75 0.30
Disco ball 1.50 1.00 0.60 0.20
Taco 1.50 1.00 0.50 0.20
A 1.25 1.00 0.40 0.15
K 1.25 1.00 0.40 0.15
Q 0.75 0.60 0.25 0.10
J 0.75 0.60 0.25 0.10
10 0.50 0.40 0.20 0.10
9 0.40 0.30 0.20 0.10
My Desire scatter 100.00 50.00 20.00 6.00

Multiply any row by your stake. Ours was $1.00.

Ultimate Slots Verdict

Danger High Voltage names itself after the round that gave us least. Fifteen spins, a column of six values with one lit at a time, and x66 arriving once in 30 spins to catch two ways at the paytable floor for $13.20. Gates of Hell promises less and paid $209.10 in 7. Behind both sits the same restriction. Wilds fill reels 2 to 5, wins start at reel 1, so a screen of wilds waits on the one reel that can never carry one. The room strobes from every wall and the grid stays legible through all of it, which is the most careful work here.

4/5 Excellent

What We Like

  • You pick your own free spins round, 15 spins with a multiplier column or 7 with a sticky wild
  • The skull pays from 2 symbols at 0.50x, the only symbol on the paytable that does
  • A sticky Q paid us $209.10 in 7 spins, off a symbol worth 0.10x for 3
  • The reels sit in a plain steel frame that the light show never crosses, so the symbols stay readable

What Could Be Better

  • One route into a bonus, 3 scatters and nothing else, so a dry run has nothing else in it. Ours went past 350 spins
  • Wilds fill reels 2 to 5 and wins start at reel 1, so a screen of wilds can still pay nothing
  • Both wild types fill a reel, but only Wild Electricity adds to the win, so the same ways completed by a Wild Fire reel pay a sixth as much

Detailed Review

Fire in the Disco, and Everywhere Else

The studio builds the reels into a disco and points the entire room at them. Walls of coloured dot-matrix panels rake in from the sides, green on the left and blue on the right, beneath a red ceiling grid, with beams crossing from top centre in purple and yellow. It ought to be unreadable. It isn’t, since the grid sits in a plain brushed steel frame that the light show never crosses, and the symbols stay legible while everything else flashes.

The symbol set looks like a list somebody lost control of. A sugar skull, a church bell, a disco ball, a taco. Big Time Gaming’s own page for the game explains it, and the explanation is a line from the Electric Six single the slot is named after: fire in the disco, fire in the Taco Bell, fire in the gates of hell. The disco ball, the taco, the bell and the name of the second free spins round all come out of one lyric.

What the audio does with that record is smarter than playing it. Two scatters on the grid and the song cuts in, properly, mid-verse. Miss the third and the music dies with the spin. It happened to us about 10 times before a bonus finally opened, and each one lands as a small, exact disappointment that no reel animation could deliver. Underneath sits a crowd cheering and applauding almost constantly, a faint techno pulse, and jolts of electricity like a tattoo gun. During the spin the bed drops away to a hush, the way the lights go down on a game show contestant.

Each round gets its own dressing. High Voltage wraps the reels in lightning arcs and round bulbs and turns the room white. Gates of Hell grows stone columns up the sides with a ram skull at each corner and vine hanging off the top. You always know which one you are in at a glance.

Where Almost 400 Spins Went

Normal play has one event worth waiting for, and it is the electric wild. Our best spin outside the free spins came to $32.10 from a single one of them, on a grid that also held two Wild Fire reels, which completed the ways without adding to them. The bar cycled them one at a time, 1 WAY X6 = $22.50 among them, which is 4 skulls in a row at 3.75x carried up by that x6. Wins in the $3 to $12 bracket came often enough to keep the balance moving.

Then High Voltage, and the round the panel sells hardest had the least to work with. It ran 15 spins, took 3 more scatters on spin 6 for 15 on top, and lit x66 exactly once in all 30. That spin paid $13.20. Two routes at 0.10x the stake apiece is all that x66 landed on, and 0.10x is where 4 of this paytable’s 10 symbols bottom out. Every winning spin we captured in that round showed 1, 2 or 3 ways on the bar.

High Voltage free spins wild reel with x66 lit and the win bar reading 2 WAYS = $13.20. $38.40 after 7 spins, and this is the one that lit. The 23 that followed did not.

Gates of Hell drew us the Q, and the Q is everywhere. By the fourth spin the bar read 36 WAYS. The last 3 spins paid $67.50, $44.40 and $68.70, and the round closed without once earning the spins it advertises on top. A sticky symbol keeps working every spin it survives, where a lit multiplier only pays on the spin it lights for. Seven spins of Gates of Hell paid $209.10. Thirty of High Voltage paid $63.80.

24 ways paying $36.00, and that is one piece of this spin rather than the whole of it.

Frequently Asked Questions

You don't until it lands. The wild carries all 6 of its values, with one of them already lit, and the rules screen does not say how that one is chosen. Over our 30 free spins we saw x22, x44 and x66 light.
The studio later built a Megapays edition with a jackpot attached, and a full sequel after that. This review covers the 2017 original, which has neither.
The bar cycles through each winning combination in turn, so a spin can print 1 WAY = $0.75 and then 2 WAYS = $0.30. Those are separate wins on the one set of reels. The corner of the grid holds the total, which for that spin was $1.05.
