How it plays
7 rules screens from the gameZombie Carnival runs six reels of four rows with 4,096 ways to win: three or more of a kind pay once they sit on neighbouring reels counted from the left, once for every way they form, and diagonal or gapped positions count for nothing. At USD 2 the zombie clown is the top symbol, USD 2.00 for three and USD 10.00 for a full six-reel way, ahead of the ringmaster at USD 6.00, the blue ogre at USD 4.00 and the helmeted zombie at USD 3.00; the four royals pay USD 0.40 to USD 1.40. A gift-box Mystery symbol turns into one random paying symbol at the end of the spin, in ordinary play and in the feature alike.
The brain Scatter appears only on reels two to five, and two of them anywhere start 6 free spins. The Scatters that opened the round become bear Wilds and stay on the reels for the whole feature; every Scatter that lands afterwards is consumed by the nearest Wild, which walks over to it and raises its multiplier by 1x, and if more Scatters land than there are Wilds, the spare Scatters become new Wilds. A Wild multiplies every way it completes, two Wilds in one way multiply each other, and each Scatter also adds one free spin.
Buying the feature costs 80x the stake, USD 160 at USD 2, and the opening spin of a bought round can hold two, three or four Scatters; all fifty purchases and all 56 natural features of this first run opened with exactly two Wilds. There is no Ante option.
Ordinary play and the purchase share one printed figure, 96.50%; volatility is marked high, and a 5,000x ceiling closes any feature that reaches it. The demo accepts bets between USD 0.20 and USD 240.

Verdict
Two bears, one of them at x4Across 10,000 ordinary spins the demo returned 95.90% of stake against the 96.50% in the rules, the approximate 95% band spans 77.3–114.5%, and the balance finished 410 bets down after touching 1,068.8 bets below the start. Fifty-six natural features arrived one per 179 spins, 5.6 bHz, and paid 43.3% of everything the series returned; strip out the best of them, round 7359 at 428.8 bets, and 9,999 rounds are left at 91.63%. Ordinary play itself is thin: no tumbles, 25.96% of spins paying, and only two rounds past 100 bets, both single spins of stacked clowns.
Buying was worse. Fifty tickets at USD 160 returned 0.693x their price, 39 of them below price, median 0.3975x or USD 63.60, best ticket 5.98x; 47 tickets earned at least one extra spin, but the 33 that finished at nine spins or fewer averaged 0.33x, while the 17 that reached ten averaged 1.40x.
The mechanism this log isolates is the Wild multiplier, nothing else. Every round starts with two bear Wilds at x1; in the seven natural features where neither Wild grew, the payout averaged 11.3 bets, and in the 25 where a Wild reached x4 or more it averaged 126.4 bets. Round 7359 is the whole mechanism in one place: five spins of small change, then six Scatters in a row that walked the Wilds up to x4 and x4, and spins eight, nine and ten paid USD 99.60, USD 256.00 and USD 481.20, 97.6% of the round, with the last of those three coming from x3 and x4 Wilds sharing a single way.
- One natural feature per 179 spins on average, 5.6 bHz, and 49 of the 56 extended by at least one Scatter
- Wild multipliers stack fast: 25 features reached x4 or more and averaged 126.4 bets
- Round 7359 paid 428.8 bets, with USD 481.20 on one spin from x3 and x4 Wilds in the same way
- The 80x price is the lowest in the lab's Pragmatic set, USD 160 at the USD 2 stake
- The 80x tickets returned 0.693x their price across 50 tries, 39 of them losing
- Seven natural features never lifted a Wild past x1 and averaged 11.3 bets
- Ordinary play has no tumbles and paid only two rounds above 100 bets in 10,000
- The balance sat 1,068.8 bets under the start at its lowest, on round 6162

FAQ
6 questions · answered from the logZombie Carnival RTP: what did 10,000 demo spins return?
95.90% of stake against the 96.50% printed for ordinary play and the purchase, inside an approximate 95% band of 77.3–114.5%, with the balance 410 bets down at the end. Without the best natural feature, round 7359 at 428.8 bets, the remaining 9,999 rounds returned 91.63%.
Roaming Wilds and multipliers: how do they work?
The two Scatters that start the round become Wilds at x1, and each later Scatter is eaten by the nearest Wild, which gains 1x and adds one free spin. Two Wilds in the same way multiply each other: on spin ten of round 7359 a x3 and a x4 Wild shared a way and the spin paid USD 481.20, 240 bets.
At 80x, did the USD 160 tickets come back?
No: 50 tickets returned 0.693x their price, 39 finished below USD 160, and the median ticket paid USD 63.60. The 17 tickets that reached ten spins or more averaged 1.40x, the 33 that stopped at nine or fewer averaged 0.33x, and the best ticket, number 19, paid USD 956.80.
Natural trigger rate: how many spins between features?
Fifty-six features in 10,000 rounds, one per 179 on average, which is 5.6 bHz; the longest wait was 472 rounds between rounds 3571 and 4044. The median feature paid 35.6 bets and the mean 74.2, and 13 of the 56 passed 100 bets.
Some free spins rounds paid almost nothing: why?
Because no Scatter landed to grow the Wilds: seven of the 56 natural features ended with both Wilds still at x1, and those seven averaged 11.3 bets. The smallest feature of the run, round 8715, paid 3.0 bets across seven spins.
Biggest win outside the feature?
180 bets in round 6344, USD 360 on a single spin: thirteen clowns spread over all six reels formed 36 six-of-a-kind ways at USD 10.00 each. The only other ordinary round above 100 bets was 5524 at 108 bets, and ordinary play has no tumbles to build on a hit.
