Danger! High Voltage 2 (Big Time Gaming) – Review & Demo Play

Danger! High Voltage 2: Overview

Big Time Gaming brings the disco back with a Megaways setup, 6 reels, and 2–7 symbols per reel for up to 117,649 ways. Reactions remove winning symbols and new ones drop in. The Megadozer above the grid pushes Bonus Coins that can change the flow of a spin. Trigger three or more scatters and you pick between Fire In The Disco! or Danger Danger!! free spins. I came for the soundtrack again and stayed for the coin drops and multipliers.

Slot Details for Danger! High Voltage 2

Stakes start at 20p and go up to £20, though some UK sites cap the max at £5. Volatility is very high. RTP sits around 96.64–96.66% depending on setup, with alternative lower settings in the wild. Hit frequency is 32.59%, which is roughly one win in a bit over three spins. The base game can push up to 15,730x, while the overall max is a hefty 52,980x if everything lines up.

Bonus Buy costs 100x and raises RTP to 96.77%, though that option is not available in the UK. The engine feels familiar if you played the first outing, but the coin pusher adds a fresh layer. I found the pace can vary: some rounds rattle along with rapid cascades, then the Megadozer slows things as coins teeter before dropping. It suits session play when you want swings and a shot at progressive multipliers.

Theme, Audio + Symbols in Danger! High Voltage 2

It’s a disco machine buzzing with lights, pipes and a spinning disco ball under the reels. Electric Six sets the tone and the presentation has more polish this time. Symbols match the first game: 9–A royals, a taco, disco ball, bell, and the jewelled skull. Six-of-a-kind royals pay 0.3x to 0.5x, premiums pay 0.6x to 2.5x, with the skull top at 2.5x for six. Wilds appear on reels 2–5 and substitutes for pays.

The My Desire Heart scatter triggers the bonus when three or more land. In the base game, Bonus Coins can add multiplier wilds at x2, x3 or x5, so even modest lines can climb. That, paired with Reactions, keeps small chains alive between the bigger hits. The symbol set is tight, payouts are clear, and the wild positions mirror the original. It’s easy to read the reels and spot where the next drop might pay.

Bonus Features in Danger! High Voltage 2

Reactions clear out wins and let more symbols drop in. The Megadozer can push one or more coins on any spin or during a reaction. In the base, a coin can add a scatter, increase the current spin win multiplier by +1, or place a multiplier wild of x2, x3, or x5. It feels balanced: sometimes you get a quick +1, other times a coin lands at the right height and flips a line into something tidy.

Three or more scatters launches the choice: Fire In The Disco! or Danger Danger!!. Both lean on the Coin Dozer, but they play very differently. Fire In The Disco! grants persistent wilds for two wins or +1 spin per coin. Danger Danger!! starts a Feature Wild Multiplier and scales it during the round, with coins adding wilds that match the current value. Retriggers vary by mode, so the spin maths shifts a lot.

From my sessions, Fire In The Disco! drops more wilds across more reels and can feel busy. Danger Danger!! builds the multiplier and then looks for a timely coin on reels 3 or 4 to land a big connect. I tend to split time across both. If coins rain nicely, either can pop. When coins are shy, Fire In The Disco! keeps you nudging along; when the multiplier climbs, Danger Danger!! is the one that can break out.

Fire In The Disco! Free Spins – Danger! High Voltage 2

You start with 6 free spins. Each Bonus Coin either adds a persistent wild that remains for the next two wins or gives +1 spin. Scatters retrigger from the ends only: reels 1 and 6. Two scatters add +2 spins, and you get +2 more for each scatter beyond the second. This mode spaces wilds well and can stack wins over several reactions. When coins are dropping, the screen gets busy fast and totals climb in steps.

Danger Danger!! Free Spins – Danger! High Voltage 2

You start with 12 free spins and a Feature Wild Multiplier set at x2. Coins can increase that multiplier by +1, and coins landing on reels 3 or 4 place a wild with the current multiplier on the grid. Retriggers need three or more scatters for +2 spins, plus +2 for each extra scatter. This mode is all about timing and the ramp. When the multiplier grows and a coin hits a central reel at the right moment, it can jump.

Expert Verdict on Danger! High Voltage 2

The first game had a freaky charm with its wild reels and sticky play. Here, the Megadozer brings a modern twist and a different rhythm. Features might not feel as off-the-wall, but the ceiling is higher at 52,980x, and the base can throw a surprise with multipliers stacking in a single spin. I rate it a proper sequel: familiar vibe, tightened presentation, and two bonuses that reward different moods.

When I want length and a climb, I take Danger Danger!! and let the multiplier cook. If I’m chasing quick momentum, Fire In The Disco! does the job with persistent wilds and regular coin action. Volatility is very high, RTP sits well for this style, and the hit rate keeps things ticking over. It’s a solid return to the dancefloor and a good shout when you fancy Megaways with coin-led modifiers.
