Fire in the Disco opens with 6 free spins, and two different events add more: a Megadozer coin that reveals one extra spin, and two or more Scatters at the end of a spin, worth 2 spins plus 2 per Scatter beyond the second. A feature enters the retrigger figure once it has played more than its 6 starting spins, whichever event added the spin. In run one coins added 156 spins across 26 of 29 natural features and Scatter awards 10 spins in 3, and among the 50 bought features coins added 279 spins in 45 and Scatter awards 14 in 6; in run two coins added 145 spins in 25 of 28 natural features and 253 in 43 of 50 bought ones, Scatter awards 6 spins in 3 and 18 in 8.

How it plays

8 rules screens from the game

Six reels hold up to seven symbols each on every spin, which gives up to 117,649 ways. A way pays when matching symbols sit on adjacent reels starting from the leftmost one, and every winning symbol except a Scatter then drops out in a Reaction, with new symbols falling in from above. Only the jewelled skull pays for a pair, and six of them are worth 2.5x the stake.

The Megadozer, a coin pusher mounted over the reels, can shove Bonus Coins onto the grid during any spin or Reaction. In the base game each coin turns into one of three things: +1 on the win multiplier of the current spin, an extra Scatter, or a Wild that is plain or carries x2, x3 or x5.

A choice opens when three or more Scatters land. Fire in the Disco gives 6 free spins in which a coin becomes either a Wild that stays on screen for the next two wins or one more free spin. Danger Danger gives 12 free spins in which coins raise a Feature Wild Multiplier that starts at 2, or drop a Wild carrying the current value.

Extra spins inside the feature also come from Scatters: two or more at the end of a Fire in the Disco spin add 2, plus 2 for every Scatter beyond the second, while Danger Danger needs three for the same award. The Bonus Buy costs 100 times the stake and leads to the same choice screen. The game data declares 96.77% RTP for both the base game and the buy; the demo stake runs from FUN 0.20 to FUN 15.

Verdict

Coins stretch, Scatters barely

Danger High Voltage 2 has returned 101.38% and 93.78% in its two demo runs at FUN 1, 97.58% pooled over 20,000 spins and 483.9 bets short of even money, the declared figure being 96.77%, and all 57 natural features plus all 100 bought ones were played as Fire in the Disco, so Danger Danger remains unmeasured. The extra spins came from coins in both runs: +1 coins added 156 and then 145 spins to the natural features, end-of-spin Scatter awards 10 and then 6, and the longest features, 55 spins on round 6370 of run one and 34 on round 6948 of run two, paid 421.2x and 358x; features that reached ten spins took 75.9% and 70.9% of the bonus-round money.

Fifty-seven natural features came over the two runs, 29 and then 28, one per 350.9 spins or 2.85 bHz, and the full feature rounds, trigger spins counted, paid 99.82x the stake on average, 86.05x at the median, 29.2% of everything returned; 26 of them cleared 100x and seven ended under 20x, while round 606 of run two paid nothing from its six spins, the first empty feature on this page. Waits ran to 1,369 spins in run one and 1,531 in run two, and run two's last feature, round 8868, was followed by 1,132 spins without one; the bought features behaved much like the natural ones, 253 extra spins from coins in run two against 18 from Scatters, and seven of run two's fifty tickets never grew past six spins.

The FUN 100 ticket has returned 1.007x of price over 100 buys, 1.0002x and then 1.0138x, with 65 tickets below their price, a FUN 84.55 median, nine tickets over 2x and none over 5x, the best FUN 490.30 on ticket 36 of run one and FUN 400.55 on ticket 25 of run two, the worst FUN 2.25 on ticket 1 of run two. In the base game the Megadozer's multiplier rounds, 8.65% and then 8.02% of spins, earned 41.92% and 44.91% of base-game money, and run two produced six base rounds above 100x against two, led by 245.2x on round 4034 from a single reaction at x4; wins showed on 33.34% and 32.4% of spins, the longest dry stretches were 20 and 21 spins, and the balance closed 138.1 bets up and then 622.1 down, the pooled low of 602.9 bets falling on run two's spin 3959.

Measured upsides
  • Twenty-six of 57 natural features cleared 100x, and the pooled average is 99.82x per feature
  • A single x4 reaction on round 4034 of run two paid FUN 240, a 245.2x base round
  • Coins added 156 and 145 extra spins to the natural features, stretching one to 55 spins and one to 34
  • The FUN 100 ticket came back at 1.007x of price over 100 buys, nine of them past 2x
Measured downsides
  • Triggers without a buy came once per 350.9 spins, with waits of 1,369 and 1,531
  • Seven of 57 features stayed under 20x, and round 606 of run two paid nothing from its six spins
  • Sixty-five tickets in a hundred paid less than FUN 100, seven of run two's after only six spins
  • Danger Danger was never chosen: 157 features across two runs, all Fire in the Disco
Verdict by run · 2 runs · tap a run to read it
Run 01·2026-09-27·101.38% Every feature in this log, 29 natural and 50 bought, was played as Fire in the Disco, so Danger Danger has no figures here.

Every feature in this log, 29 natural and 50 bought, was played as Fire in the Disco, so Danger Danger has no figures here. In those features the extra spins came mostly from Megadozer coins: across the 29 natural features +1 coins added 156 spins and end-of-spin Scatter awards only 10, and the 15 features that reached 10 spins or more collected 75.9% of the bonus-round money. The 55-spin record took 45 of its extra spins from coins and paid 421.2x the stake, 420.0x of it in free spins wins.

Over 10,000 ordinary spins at FUN 1 the series ended at 101.38%. In the base game the Megadozer works mostly through the win multiplier: the 865 spins that reached x2 or higher, 8.65% of the series, paid 41.92% of base-game money. The single best base spin, 293.9x at round 3380, did not need the multiplier at all; one Reaction dropped Wilds marked x3, x2 and x2 and paid 289.35 FUN by itself.

The fifty FUN 100 purchases broke even on average, 1.0002x the price, with a median of 0.8555x and 33 of 50 short of the cost. Longer tickets tended to pay more, but not reliably: five never left the 6 starting spins, the longest ran 23 and paid 240.35 FUN, and the best, FUN 490.30, took 20.

Run 02·2026-09-30·93.78% Round 4034 needed no free spins and no Wild: the Megadozer pushed three +1 coins onto the first reaction, the spin multiplier reached x4, and that one reaction paid FUN 240 of a 245.2x round.

Round 4034 needed no free spins and no Wild: the Megadozer pushed three +1 coins onto the first reaction, the spin multiplier reached x4, and that one reaction paid FUN 240 of a 245.2x round. Six base rounds passed 100x in all, 210.6x on round 7224 from a Wild-covered first screen among them, against two in the first run; rounds whose win multiplier reached x2 or more were 8.02% of the series and took 44.91% of the base-game money, x1 rounds FUN 3,796.45, x2 rounds FUN 2,049.05, x3 FUN 651.35, x4 FUN 319.90 and the three x5 rounds FUN 74.15, and the coins themselves arrived 8,401 times, 6,542 of them Wilds, 1,127 of those carrying x2, x3 or x5.

Twenty-eight Fire in the Disco features opened one per 357.1 spins, 2.8 bHz, and every one of them was the lab's choice again, so Danger Danger still has no figures; the features paid FUN 2,597.05 over their whole rounds, 27.7% of the return, 92.75x on average and 74.88x at the median, with twelve over 100x, four under 20x and round 606 paying nothing from its six spins. Coins did the stretching once more, 145 extra spins across 25 features against six from end-of-spin Scatters in three: round 6948 grew from 6 spins to 34 on coins alone and paid 358x, its eighth spin worth FUN 81.70, rounds 5709 and 7735 ran 25 and 22 spins for 157.65x and 190.35x, and the 13 features with ten spins or more earned 70.9% of the bonus-round money, while round 4831 made 160.7x in eight. The waits were uneven, 1,531 spins after round 606 and 939 after round 2583, and nothing came after round 8868.

Tickets at FUN 100, fifty of them, returned FUN 5,069.10, 1.0138x of price, with 18 covering the price and five passing 2x, ticket 25 at FUN 400.55 from 15 spins with FUN 216.65 on its twelfth; seven tickets never left the six starting spins and three of them paid under FUN 6, ticket 1 FUN 2.25, the median came back at FUN 84.55, and ticket 50 ran longest at 29 spins for FUN 181.75. In the ordinary series something paid on 32.4% of spins at a 0.625x median, 6,760 spins paid nothing, and 21 spins from round 1116 made the longest blank stretch; the balance first went ahead on spin 56, peaked 265.4 bets up on spin 593 and was ahead on 2,200 spins in all, the last of them 8634, but bottomed 741 bets down on spin 3959 and closed 622.1 short, 93.78% of FUN 10,000 at FUN 1, the 2,000-spin blocks returning 88.9%, 78.8%, 109.3%, 126.3% and 65.7%.

lab note · 2026-09-28

Corrected 28 September 2026: the free spins figures were recomputed after a fix in how the rig reads Big Time Gaming responses. The first win of a spin that triggers the feature had been counted twice in the base game, so 16 of the 29 features looked smaller than they were. Free spins money went from FUN 2,950.90 to FUN 3,000.10 (mean 103.45x the stake, median 92.45x); round wins, the 101.38% RTP, the trigger count and all 50 purchases are unchanged.

Does the second run change the Danger High Voltage 2 RTP picture?
Lab answer

Yes, it lowers it: 93.78% after 101.38%, 97.58% pooled over 20,000 FUN 1 spins, still above the declared 96.77%. Natural bonus rounds supplied 30.5% and then 27.7% of each run's return, and the base game's multiplier rounds 41.92% and 44.91% of its money.

Why is there still nothing about Danger Danger?
Lab answer

Because all 157 features on this page, 57 natural and 100 bought, were played as Fire in the Disco at the choice screen. Danger Danger, 12 spins with a rising Feature Wild Multiplier, was offered every time and never taken, so its figures remain unmeasured.

Still break-even, the 100x buy?
Lab answer

Yes: FUN 10,070.15 back for FUN 10,000 over 100 tickets, 1.0002x in run one and 1.0138x in run two; the median ticket paid FUN 84.55, 65 of the hundred fell short of the price, nine cleared 2x and none 5x; the best were FUN 490.30 on ticket 36 of run one and FUN 400.55 on ticket 25 of run two, the worst FUN 2.25 on run two's ticket 1.

What adds the extra free spins?
Lab answer

From Megadozer coins almost entirely: +1 coins added 156 spins to run one's 29 natural features and 145 to run two's 28, end-of-spin Scatter awards only 10 and 6. Run one's round 6370 reached 55 spins and run two's round 6948 34, both on coins alone; three features per run never left the six starting spins.

Which base spins paid most, and did they need the multiplier?
Lab answer

It did on round 4034, run two's best at 245.2x: three +1 coins on the first reaction set the spin multiplier to x4 and that reaction paid FUN 240. Run one's 293.9x on round 3380 came from Wild coins marked x3, x2 and x2 instead; across both runs eight base rounds passed 100x, and the multiplier reached x7 once in run one and x5 three times in run two.
