How it plays

13 rules screens from the game

Reel heights change on every spin, two to seven symbols on each of six reels, for up to 117,649 Megaways, and a win needs matching symbols on consecutive reels starting from the leftmost one. Winning symbols are removed and the empty positions refill from above, with any new win added to the round. Six Wolves pay 50x the bet, and a pair of Wolves already pays 2x, something no other symbol does.

Three pigs sit among the regular symbols, and every second tumble turns them into Piggy Wilds. A Piggy Wild substitutes for everything except the Wild and the Moon Bonus scatter, and the plain Wild covers all symbols except Piggy Wilds and scatters.

Three Moon Bonus scatters in the base game start the Blow Down the House bonus with 11 free spins. The win multiplier starts at x1 and climbs with every win, and collected Moon scatters blow down the houses: three add 3 spins and +5 to the multiplier, six add another 3 spins and +10, and every scatter past six adds one spin.

Skipping the wait costs 90x the bet through the Buy Feature, which opens the same bonus. The demo runs the 96.05% model; the official game sheet also lists 94.11% and 90.19% versions, rates volatility 5 out of 5 and records a top payout of 30,540.35x in 100 billion simulated spins. The demo stake goes from EUR 0.20 to EUR 20.

Verdict

The multiplier needs spins to grow

At EUR 1 a spin, the 10,000-spin series returned 87.58% against the declared 96.05%; the approximate 95% CI stretches from 76.47% to 98.68%. The best round was a 323.75x free spins round at 4341, and the 9,999 spins without it add up to 84.35%. Hits arrived on 37.62% of spins, once every 2.66, with a median hit of 0.8x.

The game sheet splits its 96.05% into 74.70 points from the base game and its features and 21.35 from free spins. This series matched the first part, 75.57% of the stake outside free spins, but the free spins brought back only 12.01%. Seventeen triggers in 10,000 spins, one per 588.2, is a thin sample, and 13 of the 17 stopped at the opening 11 spins.

Tickets for the bonus cost EUR 90, and the 50 bought here averaged 0.6461x the price, the median ticket paid 0.5242x and 39 of 50 fell short. No ticket reached twice the price: the best, EUR 128.35 or 1.4261x, and the worst, EUR 11.00. Thirteen tickets ran past 11 spins, one of them to 19.

The bonus pays late because the multiplier does the work. In the natural features the multiplier averaged x1.00 on the first free spin and x10.35 on the last, and spins played at x5 or higher collected 92.9% of that money. The best feature, 323.5x at round 4341, took EUR 293.60 of it on the 14th and last spin, played at x17.

Measured upsides
  • Everything outside free spins returned 75.57% of the stake, close to the 74.70 points the game sheet gives to the base game.
  • The best natural feature paid 323.5x the stake in free spins wins, and the best base spin paid 167.35x.
  • Hits came on 37.62% of spins, and the longest run without a win was 17 spins.
  • Late free spins can pay big: spins at x5 or higher collected 92.9% of the natural free spins money.
Measured downsides
  • Triggers without buying were rare, one per 588.2 spins, with a 1,366-spin wait between rounds 2838 and 4205.
  • No bought feature reached twice the 90x price, and 39 of 50 paid back less than EUR 90.
  • Free spins returned 12.01% of the stake against 21.35% on the game sheet.
  • Drawdown from the best point hit 1,280 bets, and a 100-bet bankroll ran out by spin 318.

FAQ

6 questions · answered from the log
Big Bad Wolf Megaways RTP: why 87.58% instead of 96.05%?
Lab answer

The demo returned 87.58% over 10,000 spins at EUR 1, and its approximate 95% CI runs from 76.47% to 98.68%. The whole gap sits in the free spins, which returned 12.01% of the stake against the 21.35 points the game sheet assigns to them, while the rest of the game returned 75.57% against 74.70.

Free spins trigger rate: how many spins per bonus?
Lab answer

Free spins started 17 times on their own over 10,000 spins, on average every 588.2 spins or 1.7 bHz. The longest wait was 1,366 spins, from round 2838 to round 4205, and 13 of the 17 features ended at the opening 11 spins.

90x for the bonus: did it pay back?
Lab answer

Each of the 50 bonuses cost EUR 90 and returned 0.6461x the price on average, and the median ticket paid 0.5242x. Only 11 of 50 got back the EUR 90, and the best ticket paid EUR 128.35, 1.4261x.

Free spins multiplier: how far does it climb?
Lab answer

It starts at x1 and climbs with every win, and blowing down a house adds +5 or +10. In the 17 natural features the last spin played at x10.35 on average, and spins at x5 or higher paid 92.9% of the free spins money.

Piggy Wilds: when do the pigs turn Wild?
Lab answer

Every second tumble turns the three pig symbols into Piggy Wilds, so they appear only inside a chain of wins. Tumbles followed 37.62% of the 10,000 spins, since every win starts one, and the best base spin, 167.35x at round 6226, ran 11 steps.

Max win of Big Bad Wolf Megaways: how big can a round get?
Lab answer

The official game sheet records a top payout of 30,540.35x the bet in 100 billion simulated spins for the 96.05% model. The biggest round in this series paid 323.75x, a natural feature at round 4341.
