Danger High Voltage Slot Review, RTP & Free Play

Danger High Voltage Review

Danger High Voltage is one of those slots that once played, sticks with you and keeps you coming back for more. The theme is this one is a bit harder to determine, but as the name suggests, it is based on the dangers that come when playing with high voltage, only in this slot, that high voltage relates to big wins. Designed with six reels and offering 4,096 ways to win, this high-energy impact slot offers an electrifying background that changes colour as the game heats up and of course, with two different free spin features and wild symbols to help boost wins, it is one not easily forgotten.

Looks & Feel:

The look and feel of Danger High Voltage is classic in many ways, with it almost taking on a disco-like appearances. Symbols wise, there are disco balls, a gold bell, and a taco (not sure how that fits into its theme). The balance of symbols are letters and numbers, and while these generally are lower paying, in this game and its free spin feature, it is those smaller symbols that can bring the biggest wins.

As one would expect, there are two features to mention; this includes the Full Reel Wilds and free spins. What is nice is that each has huge potential to deliver big wins, and as such, you quickly realise why this slot is ranked high in popularity and has helped to make Blueprint Gaming a household name.

Bonus Features:

Full Reel Wilds: Full reel wilds come in two ways; the first is when it appears as a stacked wild on the reel. This will see it help to complete win by matching all other symbols except the free spin bonus symbol. The other is when it becomes electrified, which then takes that stacked wild, and adds a multiplier of six to all wins. Considering the wild can appear simultaneously on reels 2, 3 and 5, the wins this wild can deliver are almost unimaginable!

Free Spin Feature: The free spins are triggered when three or more of the free spin bonus symbol stops on the reels. When this occurs, you have two choices, select either the High Voltage Free Spins or the Gates of Hell Free Spins.

In Gates of Hell: seven free spins are awarded, and before the free spins begin, one symbol is chosen to act as a sticky wild. Anytime a full reel is sticky wilds is achieved; an additional three free spins will be added to the remaining free spins.

In High Voltage Free Spins: fifteen free spins are awarded, and with those, the High Voltage wild can appear to multiply wins up to 66x! If three additional free spin symbols appear, fifteen additional free spins will be added to those remaining, and with this feature, the big wins can really add up to something special.

Danger High Voltage RTP

The RTP for Danger High Voltage is 95.67%, which is more than acceptable and well within acceptable standards.


Make no mistake; Danger High Voltage is a high variance slot machine that can take its time to trigger the free spins, which is its main feature. However, it is one that can also deliver huge wins as a result of its increasing multiplier when the free spins are active. It allows for smaller bets, so a reasonable bankroll and time spent playing it can really payout. The graphics are nice, as are its sounds, but it is that anticipation of a big win that really makes this one special.
