Separate media session at FUN 1: High Voltage Free Spins from media spin 32, 15 spins and FUN 41.75. Recorded in a separate browser session, outside the statistical samples.

Across the whole run the 57 natural bonuses split into 20 under 20x, 16 between 20x and 50x, 13 between 50x and 100x and 8 at 100x or more, and together they made up 39% of everything the game returned. The wait between two triggers ran from 8 to 904 spins. Payout figures here are FS-only, in ordinary stakes; the trigger payout is excluded.

High Voltage Free Spins start with 15 spins, and three or more Scatters during the feature add 15 more. The share shown counts features that went past 15 spins: 2 of the 57, round 226 with 162.0x and round 2088 with 158.3x, both 30 spins long.

How it plays

7 rules screens from the game

Danger High Voltage runs on six reels of four rows, 4,096 ways counted from the leftmost reel to the right, while the Scatter pays anywhere. At FUN 1 six sugar skulls, the top symbol, pay 25.00, six bells 5.00 and six 9s 0.40.

Two Wilds fill a whole reel and appear only on reels 2 to 5: Wild Fire, a plain substitute, and Wild Electricity, which multiplies every win it takes part in by 6, so two of them in one win mean x36. Neither replaces the Scatter.

Scatters pay in any position, 6, 20, 50 or 100 times the stake for three to six of them, and three or more open a choice between two features played at the triggering stake. High Voltage Free Spins give 15 spins in which a High Voltage Wild on any of the middle four reels lights one multiplier from x11 to x66 for the wins it touches, and three more Scatters add another 15. Gates of Hell Free Spins give 7 spins in which one symbol becomes a Sticky Wild on reels 2 to 5, and every reel filled with four of them adds 3 spins.

Declared RTP on this demo server is 96.22%, the client configuration lists a 28,190x ceiling, the stake range is FUN 0.20 to FUN 20, and no bonus purchase is offered. Every feature in this series was played as High Voltage Free Spins, so Gates of Hell has no measurements here.

Verdict

The lit Wild is the feature

The series of 10,000 FUN 1 spins returned 87.05% against the declared 96.22%; the approximate 95% CI spans 71.63% to 102.47%. Spins paid often, 42.09% of the time, but the median hit was 0.4x the stake, and the best round, a 424.2x feature at round 3815, lifted the total; without it the rest came to 82.81%.

Away from the feature, the multiplier Wild does most of the work. Spins that showed a Wild Electricity reel were 7.53% of the series yet paid 54.0% of base money, 3.81x on average, while Wild Fire spins without it, 24.00% of the series, paid 22.0%, and the 68.47% of spins with no Wild reel returned 24.0%. No base spin went past 61.2x.

High Voltage Free Spins came 57 times, once per 175.4 spins, and averaged 59.59x the stake with a 34.6x median; two of them retriggered to 30 spins. Inside them the lit multiplier decided everything: 574 of 915 spins had no High Voltage Wild and paid 2.8% of the feature money, spins at x33 and x44 paid 62.6% between them, and in the record feature the 14th spin alone brought 330.0 of its 418.2.

Measured upsides
  • Wild Electricity spins, 7.53% of the series, paid 54.0% of base-game money.
  • Once per 175.4 spins the free spins arrived, averaging 59.59x the stake.
  • Something was paid on 42.09% of spins, and no dry run went beyond 20 spins.
  • The record feature at round 3815 paid 424.2x the stake.
Measured downsides
  • At 87.05% the series finished well under the declared 96.22%.
  • Most wins were small: the median hit came to 0.4x the stake.
  • 574 of 915 free spins had no lit High Voltage Wild and paid 2.8% of feature money.
  • Its worst slide cost 1,564.9 bets; a 100-bet budget would have lasted 177 spins.

FAQ

6 questions · answered from the log
Why did Danger High Voltage return 87.05% instead of 96.22%?
Lab answer

The approximate 95% CI of this 10,000-spin FUN 1 series, 71.63% to 102.47%, still covers the declared 96.22%. The best round, a 424.2x feature at round 3815, carried much of the total; take it away and the remaining rounds come to 82.81%.

What does Wild Electricity do?
Lab answer

Lab answer

The whole log, 57 features, was played as High Voltage Free Spins, 15 spins with a High Voltage Wild worth x11 to x66. Gates of Hell, 7 spins with a Sticky Wild, was never chosen, so the page has no figures for it.
