Danger High Voltage: Original, Megapays and Megaways Sequel
Danger High Voltage has three Big Time Gaming editions. The original and Megapays use 4,096 ways with a choice of two free-spin features; Danger High Voltage 2 changes to Megaways and adds a Megadozer coin machine. The useful comparison is held wild positions versus growing wild multipliers, with a separate progressive layer in Megapays.

All three Danger High Voltage games at a glance
Compare the two 4,096-ways editions with the Megaways sequel. The progressive layer, reel multiplier and persistent wild are separate features:
| Game | Year | Layout | RTP | Max win |
|---|---|---|---|---|
| Danger High Voltage | 2017 | 6×4, 4,096 ways | 95.67% supplier listing | Read installed original cap |
| Danger High Voltage Megapays | 2022 | 6×4, 4,096 ways | 96.18–96.39% supplier range | 39,620x excluding jackpots |
| Danger High Voltage 2 | 2024 | 6 reels, up to 117,649 ways (Megaways) | 96.77% supplier graphic | 52,980x supplier graphic |
The original’s supplier page lists 95.67%. Directly inspected supplier stat graphics give Megapays 96.18–96.39% and a 39,620x limit excluding jackpots, and the sequel 96.77% and 52,980x. Megapays has a separate progressive system, and Danger High Voltage 2 changes the reel engine to Megaways. The sequel’s old 96.66% comparison figure should not be treated as the return or cap of every installed version. Match the full title, selected stake option and any progressive contribution in the actual help. The distinctions below concern identifiable mechanics rather than a supposed universal ranking by RTP.
Every game, reviewed
1. Danger High Voltage (2017)
The original is a six-reel, four-row game with 4,096 ways, rather than Megaways. Its feature identity is the choice between High Voltage and Gates of Hell. The former centres on enhanced wild effects, while the latter holds designated wild symbols during its feature. The board’s height stays fixed; the two choices do not create two separately staked grids. Its Electric Six setting ties music and flashing symbols together, but the way a wild behaves is the useful basis for comparison with the later releases.
2. Danger High Voltage Megapays (2022)
Megapays keeps the 4,096-ways structure and adds progressive pools. Its supplier description gives High Voltage fifteen free spins with enhanced wild multipliers on the middle four reels, while Gates of Hell begins with seven spins and a chosen sticky-wild symbol. The progressive system is separately funded by part of wagers and can be triggered at any permitted stake. A linked pool’s cash display does not make every ordinary reel win progressive. Compare this edition for that additional prize layer while keeping the underlying two feature choices distinct.
3. Danger High Voltage 2 (2024)
Danger High Voltage 2 switches to Megaways and adds the Megadozer above the reels. Coins can change the current base-round multiplier, add a scatter or place a multiplier wild. Three scatters offer Fire in the Disco or Danger Danger. Disco starts with six spins; a coin can add a wild lasting for the next two wins or an extra spin. Danger Danger starts with twelve spins and a feature wild multiplier of 2, which coins can increase or use for a newly added wild. Count wins, not spins, when reading Disco’s persistent-wild lifetime.
Not Every Slot Like Danger High Voltage Runs Megaways
A fixed 6×4 arrangement gives 4⁶ = 4,096 full-length ways. Megaways changes the symbol counts, so the displayed number varies within its stated limit. Neither engine has two independent reel sets here. For a true two-set comparison, Da Vinci Diamonds Dual Play connects upper and lower boards. A ways count measures possible symbol routes, not the number of prizes that must be paid on that spin.

Return settings and complete wagers
Theoretical expected loss per £100 wagered at an identified original setting:
| Game | House edge | Per £100 wagered |
|---|---|---|
| Danger High Voltage (95.67%) | 4.33% | £4.33 |
| Danger High Voltage 2 (96.77% supplier graphic) | 3.23% | £3.23 |
Expected loss is calculated on total wagers, not a prediction for a session.
At 95.67%, £100 × 4.33% gives £4.33 theoretical expected loss; at the sequel’s supplier-shown 96.77%, the equivalent is £3.23. That is a long-run calculation of wagers, not a budget for an individual hundred-spin session. A progressive version also needs its complete return and contribution; a standalone reel percentage is insufficient. An extra stake changes turnover, so compare total cash wagers rather than just the percentage. See the Responsible Gambling guide for limits and support.
Two wins is a different lifetime from two spins
Suppose a persistent wild is added during Disco and the next paid feature spin has no qualifying win. The supplier’s “next two wins” wording does not describe a two-spin countdown. Conversely, if a sequence produces several evaluated wins, reading only the spin number can conceal how much of that lifetime has been used. Follow the actual wild indicator and the win sequence. This explains the duration unit without inventing a promise about when a qualifying win arrives.
A chosen sticky symbol in Gates of Hell follows a different instruction: its held position belongs to that feature’s rules. A reel-level count and a win-level counter are therefore not interchangeable. The screenshot’s coin dozer belongs to the sequel; copying its coin awards into the original would describe a feature the earlier game does not have.
A growing multiplier changes the award, not the stake
As an illustrative calculation, a qualifying £2 reel award at 3x pays £6. If a later award is £1 at 4x, that adds £4, producing £10 across those evaluations. Applying the final 4x to both underlying awards would give £12 and misread the progression. Each award needs the multiplier applicable under that feature’s rules. Wild combinations also need the exact paytable treatment; do not assume that every visible multiplier simply adds together.
The Megadozer’s display is separate from the qualifying reel combination. A coin may modify the board or counter, while the reel award is calculated from the symbols that actually qualify. A large coin animation therefore does not itself establish a cash prize. Read the credited round total after its effects resolve, and distinguish an added scatter, an extra feature spin and an awarded wild.
History and legacy
The original brought the Electric Six setting to a fixed-ways game in 2017. Megapays followed in 2022 with a progressive layer, while the 2024 sequel introduced Megaways and the coin dozer. This sequence separates an added award system from a changed reel engine. Bonanza provides BTG’s earlier reacting-Megaways comparison, with its own multiplier and trigger rules.
Why this family still matters
The retained feature choice gives the family a recognisable structure, but the names and state change in the sequel. A held symbol, a wild counted through two wins and a wild whose multiplier grows are different instructions. Those differences matter more than treating each new release as the same game with a larger theoretical maximum.
Beyond the reels
Big Time Gaming’s site identifies its British supplier status; the UK Gambling Commission provides the relevant public record. It is incorrect to claim that BTG lacks a supplier licence simply because a historical ownership description changes. The casino’s authorisation and installed configuration remain separate questions. Availability of a worldwide supplier feature does not establish that it appears at every UK operator.
Compare wild positions, lifetimes and values
Choose Original for the earlier fixed-ways feature choice, Megapays for a separate progressive layer, or Danger High Voltage 2 for changing reel heights and Megadozer state. Someone comparing retained wild positions should read Gates of Hell; someone comparing wild lifetimes and increasing values should read the sequel’s two choices. These distinctions do not promise a particular win frequency, session duration or better next outcome.
Recorded awards need the exact edition
An aggregator’s reported award total or sample return is not a largest independently established player payout. A credible result needs the exact title, stake, configuration and award type. A progressive pot must also be identified separately from ordinary reel wins. This comparison does not use an unexplained “average win” figure to rank the family, since a sample average cannot establish the paytable ceiling or a likely individual result.
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 separate progressive prize layer | Danger High Voltage Megapays | Four linked progressive jackpots on the same base game |
| A genuine Megaways experience | Danger High Voltage 2 | Changing reel heights and the Megadozer feature |
Our verdict on Danger High Voltage
Editorial assessment: the strongest comparison is fixed ways versus Megaways, then held wilds versus wild lifetimes and growing multipliers. Megapays adds a separately linked prize system.
| Features | Two feature choices retained across different engines |
|---|---|
| Win potential | RTP and cap belong to the exact configuration, not a title family |
| Design | Electric Six provides the shared musical setting |
| Playability | A progressive display and a base-game multiplier are different units |
Compare the fixed-ways original first, then choose Megapays for its linked pools or the sequel for Megadozer and changing reel heights. Read the wild’s duration before assuming it remains throughout the bonus. The SlotsLike archive gives wider family navigation.
