Danger! High Voltage 2 (Big Time Gaming) Slot Review

Danger High Voltage 2: Slot Overview 

Seven years after the release of the cult classic Danger High Voltage, Big Time Gaming returns to the dance floor with a flashy, amplified sequel—Danger High Voltage 2. Retaining the wild spirit and disco-inspired chaos of the original, this sequel cranks up both the spectacle and the winning potential. Featuring music from Electric Six, a high-energy light show, and two revamped bonus rounds, the game delivers an even more eccentric take on the retro-disco slot formula. 

At its core, Danger High Voltage 2 is a Megaways slot, boasting up to 117,649 ways to win and powered by a slew of advanced mechanics including the Coin Dozer feature, Bonus Coins, persistent wilds, and unlimited multipliers. While it shares its thematic DNA with the first game, it’s far from a reskin—the mechanics are more involved, and the gameplay, while still unpredictable, feels both more structured and more explosive.

Design and Graphics 

Danger High Voltage 2 trades the gaudy grid-box of its predecessor for a steampunk disco-mech hybrid. The game is set within a pulsating contraption of pistons, chrome coils, and flashing LEDs, wrapped in a chaotic energy that combines industrial grit with rave culture aesthetics. The spinning grid sits center stage, surrounded by animated metallic arms and buzzing electricity, giving the sensation that this machine might just take off if it gets too excited. The reel symbols stay true to the eccentric spirit of the original: 9-A card royals, tacos, bells, disco balls, and a jeweled skull inspired by Damien Hirst’s “For the Love of God”. These symbols burst with bright colors and quirky animations. In short, everything about the visual style screams retro excess with a high-tech upgrade. 

The Coin Dozer, sitting above the reels, drops bonus coins that affect nearly every part of the gameplay, adding a fresh interactive element to the visual presentation.

Gameplay Mechanics 

Powered by the Megaways engine, each spin offers a variable grid layout of 6 reels with 2 to 7 symbols per reel, leading to a maximum of 117,649 ways to win. Winning symbols must appear on adjacent reels starting from the leftmost reel. After each win, the reaction mechanic kicks in—removing winning symbols and allowing new ones to tumble down, potentially triggering additional wins. 

A central innovation in Danger High Voltage 2 is the Coin Dozer system. Resembling the Megadozer used in Bonanza Falls, this machine may drop one or more Bonus Coins on any spin or reaction. These coins can: 

Increase the win multiplier by +1 

Add scatter symbols to the reels 

Add wild symbols with multipliers of x2, x3, or x5 

This system integrates tightly with both the base game and bonus rounds, creating a sense of anticipation and dynamism on every spin.

Sound and Music 

The Electric Six soundtrack returns in full force, adding an energetic pulse that fuels the action. Familiar anthems like Danger! High Voltage! and Gay Bar blast through the speakers, perfectly synced with win animations and bonus round triggers. The bass drops harder in free spins, and the increasing tempo of the background score reflects the rising tension and win potential. 

Sound effects also play a big role—electric zaps, bass pulses, robotic thumps, and rhythmic jingles amplify the disco-science fusion of the game. BTG has always excelled in blending sound with gameplay, and this sequel is no exception.

Bonus Features 

Fire In The Disco! 

One of the two selectable bonus rounds, Fire In The Disco! awards 6 free spins. Here, Bonus Coins from the Coin Dozer drop onto the reels, revealing: Wilds, which persist for the next two wins 

Or additional free spins 

This feature focuses on building momentum, as the persistent wilds help chain together reaction wins, while extra spins extend the sequence. It’s a volatile ride, with big hits possible if the right symbols stick early. 

Danger Danger!! 

In the second feature, Danger Danger!!, players receive 12 free spins, and Bonus Coins dropped on reels 3 and 4 either: 

Add a wild with a multiplier matching the current Feature Wild Multiplier 

Or increase the Feature Wild Multiplier by +1 

The multiplier starts at x2 and has no cap. This creates the potential for increasingly massive wins with each Coin Dozer drop, making this feature ideal for players who love the thrill of progressive multipliers. 

Scatters and Retiggers 

Landing 3 or more scatter symbols anywhere on the reels triggers the bonus round. Players then choose between the two features. Retiggers are available: 

+2 extra free spins for 3 scatters 

+2 extra spins per scatter beyond the third 

These can lead to extended sessions, especially when paired with Bonus Coins that deliver more wilds or multipliers. 

Bonus Buy Impatient players can trigger the bonus round using the Bonus Buy option for 100x the bet. This provides immediate access to the feature, with the choice between Fire In The Disco! or Danger Danger!!. It’s a high-risk but potentially high-reward shortcut to the heart of the slot’s volatility.

Betting Options and Payouts 

Min/Max Bet: €0.20 – €20 

RTP: 96.66% (base) / 96.77% (free spins purchase) 

Hit Frequency: 32.59% 

Max Win: 52,980x your stake 

Volatility: High 

The hit frequency ensures a fair number of smaller base game wins, but the slot’s true power is unleashed in the bonus rounds. The max win potential of 52,980x dwarfs the original game’s 15,746x—though it’s worth noting that this top-end number has not yet been observed in public gameplay. 

High-paying symbols award up to 2.5x the stake for 6 of a kind, while lower pays give up to 0.5x. Multiplier wilds and the progressive bonus mechanics are essential for reaching higher payouts.

Conclusion 

Danger High Voltage 2 is a brilliant follow-up to one of Big Time Gaming’s most iconic releases. It manages to retain the energy, humor, and music-driven madness of the original while introducing a range of fresh mechanics—most notably the Coin Dozer, Bonus Coins, and customizable free spin features. 

With two excellent bonus rounds, an innovative wild multiplier system, and huge win potential, the game rewards players who enjoy fast-paced gameplay, loud visuals, and electrifying volatility. While it may not hit the revolutionary status of its predecessor—largely because of how far the industry has come—it succeeds as a fun, feature-rich, and highly playable slot. 

The Fire In The Disco feature will appeal to fans of persistent wilds and chain wins, while Danger Danger!! suits players who want to stack huge multipliers with the potential for exponential wins. Either way, there’s massive win potential and entertainment value on offer. 

Whether you’re a fan of the first installment or just love BTG’s unique blend of music, math, and madness, Danger High Voltage 2 is absolutely worth a spin. Throw on your platform boots, crank up the volume, and get ready to light up the disco with 52,980x worth of high-voltage fun.
