REC · NATURAL TRIGGER

On 243 ways at a EUR 1.00 stake, a natural ten-spin bonus mixes stacked Wilds with Cerberus Emblems and ends on TOTAL WIN 37.50. Recorded in a separate browser session, outside the statistical samples.

Across the whole run the 43 natural bonuses split into 6 under 20x, 14 between 20x and 50x, 13 between 50x and 100x and 10 at 100x or more, and together they made up 39% of everything the game returned. The wait between two triggers ran from 8 to 782 spins. Payout figures here are FS-only, in ordinary stakes; the trigger payout is excluded.

Three or more Cerberus Emblems inside the bonus would add ten spins, but none of the 43 natural bonuses in this test retriggered; all of them ran exactly ten spins.

Nine fixed lines run across a five-by-three grid in the base game, counted from the left, with EUR 1.00 riding on every test spin. Five Cerberus symbols pay 150.00 and two already pay 1.50; then come the Golden Lion at 50.00, the amphora at 25.00, the helmet at 22.50 and the mace at 20.00, with A and K at 10.00 and Q, J and 10 at 7.50.

The Cerberus Emblem works as both Scatter and Wild in the base game and the bonus, and wherever they land, three of them return double the bet, four return twenty times it and five two hundred times. Separate Wild symbols only ever land stacked, covering a whole reel; this test saw them only on the second, third and fourth reels.

An Emblem count of three or more opens a ten-spin bonus, and the same count inside the bonus adds ten again. For the bonus the nine lines give way to 243 ways, so like symbols that reach at least the third reel from reel one win in every combination they form. Nothing can be bought, the rules list 96.15%, and the cap is 6,666 times the stake.

Verdict

Three Wild reels, two spins

Only two free spins in the whole test showed Wilds on reels two, three and four together. The opening spin of round 2213 paid EUR 459.00, and the tenth spin of round 8765 paid EUR 675.00 as amphoras, aces and queens each paid on 27 ways; together those two spins brought in 30.0% of the EUR 3,777.50 that 430 free spins returned.

One Wild reel was the ordinary help. It showed up on 106 free spins, which averaged EUR 13.42, and the 11 spins with two Wild reels averaged EUR 51.82, while the 311 spins with none paid EUR 650.50 between them, EUR 2.09 apiece.

Base rounds lined up by Wild reels too. The 9,150 rounds without a Wild reel averaged 0.34x, the 682 with one 1.96x and the 123 with two 9.37x, and the two that managed three averaged 92.0x; round 1865, at 151.5x, was the best of the lot without a bonus.

Every one of the 43 natural bonuses ran exactly ten spins, and half of them stopped at 54.5x or less.

Measured upsides
  • Two free spins with three Wild reels paid EUR 1,134.00 between them
  • Natural bonuses averaged 87.85x the stake on 243 ways, 43 in all
  • Base rounds with two Wild reels, 123 of them, averaged 9.37x
  • 29.61% of all rounds paid something
Measured downsides
  • Free spins without a Wild reel, 311 of 430, averaged EUR 2.09
  • Every bonus stopped after ten spins, 43 of 43 without a retrigger
  • Base rounds without a Wild reel, 9,150 of them, averaged 0.34x
  • 7,039 of 10,000 rounds returned nothing

FAQ

5 questions · answered from the log
Why do stacked Wilds matter so much in Beat the Beast: Cerberus’ Inferno?
Lab answer

They cover a full reel and substitute on every row of it. A single Wild reel lifted a free spin to EUR 13.42 on average against EUR 2.09 without one, and in the base game rounds with two Wild reels averaged 9.37x.

What did free spins pay when every middle reel was Wild?
Lab answer

EUR 1,134.00 from just two spins, 30.0% of all bonus money in the test. Round 2213 got EUR 459.00 on its first free spin, round 8765 EUR 675.00 on its tenth.

Can the Cerberus’ Inferno bonus retrigger?
Lab answer

Yes, in principle: three or more Emblems during the bonus add ten spins. In 10,000 rounds it never happened, and all 43 natural bonuses finished after ten spins.

Did the demo pay more than the listed 96.15%?
Lab answer

Yes, slightly: 97.88% over 10,000 rounds, and the approximate 95% band for this sample spans 77.12% to 118.64%. Without round 8765 the remaining 9,999 rounds would have returned 90.76%.

How frequent was the free spins bonus over 10,000 rounds?
Lab answer

Forty-three times in 10,000 rounds at EUR 1.00, about once per 232.56 rounds. The waits were uneven, and the longest ran 781 rounds before round 6581.
