Danger High Voltage is Big Time Gaming's disco-rock slot trilogy, built entirely around the Electric Six song of the same name. If you're hunting for slots like Danger High Voltage, know this first: only one of the three entries is actually a Megaways game — we sort out which is which below, along with where the figures genuinely disagree between sources.
Where to Play Danger High Voltage Slots
All three Danger High Voltage games at a glance
All three genuine Big Time Gaming entries — figures checked 6 July 2026:
| Game | Year | Layout | RTP | Max win |
|---|---|---|---|---|
| Danger High Voltage | 2017 | 6x4, 4,096 ways | ~95.7-96.2% | 15,746x |
| Danger High Voltage Megapays | 2022 | 6x4, 4,096 ways | 96.39% (single-sourced) | 39,620x (single-sourced) |
| Danger High Voltage 2 | 2024 | 6 reels, up to 117,649 ways (Megaways) | 96.66% standard | 52,980x |
The original's RTP and max win are genuinely disputed between sources rather than simple rounding — we're showing the best-supported range rather than a single false-precise figure. Megapays' figures come from a single aggregator each and couldn't be confirmed against Big Time Gaming's own page, so treat them as indicative. Danger High Voltage 2's RTP has real operator-configurable tiers (96.66% standard, 96.77% with bonus-buy, plus reduced tiers down to 86.30%) rather than one fixed number.
Every game, reviewed
1. Danger High Voltage (2017)
The original runs 6 reels and 4 rows for 4,096 ways to win, built entirely around Electric Six's 2003 disco-rock single "Danger! High Voltage" — tacos, disco balls, Day-of-the-Dead skulls and bells all reference the song's own lyrics. Two wild types appear in the base game: Wild Fire, and Wild Electricity carrying a 6x multiplier. Landing 3 or more scatters lets the player choose between two free-spins modes: High Voltage Free Spins (15 spins with a Wild Reel paying 11x-66x multipliers) or Gates of Hell Free Spins (7 spins with a sticky wild, retriggerable up to roughly 19 spins). Published RTP sits somewhere in a 95.7-96.2% range depending on source and feature choice, with a best-supported max win of 15,746x stake.
2. Danger High Voltage Megapays (2022)
Released 27 July 2022, Megapays keeps the exact same 6x4, 4,096-ways base game and both free-spins modes from the original, bolting on a Megapays(TM) jackpot feature: four progressive jackpots, the top one seeding at $300,000 and reported to climb past $1,000,000 between hits. We could only find single-sourced figures for its RTP (96.39%) and max win (39,620x), neither confirmed against Big Time Gaming's own page, so we're treating both as indicative rather than settled.
3. Danger High Voltage 2 (2024)
Released 23 October 2024, the true sequel switches to a genuine Megaways(TM) engine offering up to 117,649 ways to win — a real mechanical change, not just a bigger version of the original's 4,096-ways format. A new "Megadozer(TM)" coin-dozer machine sits in the base game, dropping Scatter, Wild and Multiplier Wild symbols, and feeds a choice of two free-spins modes: "Fire In The Disco!" (6 spins with semi-sticky wilds) or "Danger Danger!!" (12 spins with an escalating progressive multiplier wild starting at 2x). Standard RTP is 96.66%, rising to 96.77% with the confirmed 100x-stake bonus-buy engaged (not available to UK players), with reduced operator tiers down to 86.30% also in circulation. High volatility, "bordering on extreme" by one reviewer's account, with a consistently-cited 52,980x max win.
Not Every Slot Like Danger High Voltage Runs Megaways
It's easy to assume this whole family runs on Big Time Gaming's famous Megaways engine, since BTG invented it. That's not accurate here: the original Danger High Voltage and its Megapays follow-up both use a separate, proprietary "4,096 ways to win" dual-grid mechanic, not Megaways. Only Danger High Voltage 2, the 2024 sequel, actually carries the Megaways(TM) branding and mechanic, with its reel heights varying spin to spin for up to 117,649 ways — the same ways-count ceiling Big Time Gaming already used in Extra Chilli. If you're specifically looking for a Megaways experience in this franchise, the sequel is the only genuine option.

The maths: a genuine mechanical leap, not just a bigger number
What a hundred £1 spins costs at each game's confirmed published RTP:
| Game | House edge | £1 × 100 spins |
|---|---|---|
| Danger High Voltage (~96%) | ~4.0% | ~£4.00 |

✓ Calculated from the published RTPs — checked 6 July 2026
Danger High Voltage 2 edges out the original on both RTP and max win, but the more meaningful jump is mechanical: swapping the 4,096-ways dual grid for a true Megaways engine changes the game's rhythm far more than the numbers alone suggest. Session tools on our Responsible Gambling page.
History and legacy
Danger High Voltage arrived from Big Time Gaming in 2017 as a full licensed tribute to Electric Six's 2003 single, translating the song's lyrics directly into reel symbols rather than just borrowing its title. Five years later, Megapays kept the same core game intact and simply added a four-jackpot progressive layer for players chasing a bigger single hit. The real evolution came in 2024, when Danger High Voltage 2 dropped the original's proprietary ways mechanic entirely in favour of BTG's own Megaways engine — the same engine that put the studio on the map with Bonanza back in 2016 — alongside a new coin-dozer feature that changes how the bonus is actually triggered.
Why this family still matters
Few licensed-song slots have earned a genuine mechanical sequel seven years on; the jump from a bespoke 4,096-ways format to a full Megaways rebuild in Danger High Voltage 2 shows Big Time Gaming treating the theme as worth reinventing rather than just re-skinning it, the kind of format overhaul we track across our full slot series index.
Beyond the reels
Big Time Gaming doesn't hold its own separate UK Gambling Commission entry — its games reach UK players under owner Evolution's own licence. Evolution Malta Holding Limited holds active Gambling Software (Remote) and Game Host (Casino) (Remote) licences, confirmed via the UKGC public register. The original Danger High Voltage is confirmed live at a wide range of UK-facing operators including PlayOJO, William Hill, Sky Vegas, 888casino, BetVictor, Coral, Grosvenor and Ladbrokes.
What players say
Long-time BTG fans tend to rate the original as the purest expression of the theme, valuing its choice of two distinct free-spins modes over a single fixed bonus. Megapays draws interest mainly from progressive-jackpot chasers rather than players comparing base-game RTP, while Danger High Voltage 2 has won over players specifically looking for a proper Megaways sequel rather than a reskin of the 2017 original.
Big wins: what we found instead
We couldn't pin down a single documented big win — the kind tied to a named player, a specific site and a verified date — for any Danger High Voltage game, despite checking general searches, streamer-specific searches and casino big-win writeups. What does exist is a community-aggregated statistic from SlotTracker.com, drawn from over 34,000 tracked spins across 108 players, showing a headline tracked win of €47,760 at 2,388x. That's a crowd-sourced average-of-many-sessions figure rather than a single verified event, so we're citing it with that caveat rather than presenting it as a documented record.
The best Danger High Voltage slot, Megaways or not
| If you want… | Play | Why |
|---|---|---|
| The original licensed-song classic | Danger High Voltage | Two distinct free-spins modes and the game that started it |
| A shot at a life-changing jackpot | Danger High Voltage Megapays | Four linked progressive jackpots on the same base game |
| A genuine Megaways experience | Danger High Voltage 2 | 117,649 ways, a new Megadozer feature, and the highest max win |
Our verdict on Danger High Voltage
Sister Slots score: 7/10 — a genuinely distinct licensed-song trilogy that earned its sequel rather than just extending the brand.
| Features | 7/10 — the switch to a true Megaways engine in DHV2 is a real structural change, not a coat of paint |
|---|---|
| Win potential | 7/10 — a confirmed, if source-disputed, climb from 15,746x to 52,980x across the family |
| Design | 8/10 — the Electric Six tie-in still feels distinctive nearly a decade on |
| Playability | 7/10 — the original's dual free-spins choice gives it more replay variety than most fixed-bonus slots |
Play here if you want a licensed-theme slot that actually earned a mechanically different sequel. Look elsewhere if you assumed the whole trilogy runs on Megaways — only the 2024 sequel does.
