Big Bad Wolf: Pigs of Steel

Which Free Spins tier a player reaches in Big Bad Wolf: Pigs of Steel decides its starting multiplier outright — a 1x, 2x, or 3x head start depending on how many Scatters land. Quickspin's high-volatility sequel to the original Big Bad Wolf keeps the same 5-reel, 3-row, 25-payline frame as its predecessor, running at 96.14% RTP, an 18,173x win ceiling, and a bet range of 0.20 to 100.

Base game wins run on Tumbling Reels: a winning combination clears from the grid, new symbols drop in to fill the empty spaces, and the process keeps going until a spin stops producing new wins. Two systems build up alongside those tumbles. Piggy Wilds convert the red pig symbol into a Wild after two consecutive tumbles, the green pig after four, and the blue pig after six. Separately, the Pigs of Steel mechanic tracks how many pig symbols have been cleared from the reels during those wins — three removed grants pig symbols level 1 protection, and six removed grants level 2, with protected pigs shedding a layer of protection rather than disappearing each time they'd otherwise be cleared, until every layer is gone.

Scatters decide which of three Free Spins variants gets triggered. Three Scatters open the Bonus Game with a 1x starting multiplier and keep the base game's features running as normal. Four Scatters step up to the Super Bonus Game, starting at 2x, where any Pigs of Steel protection already built stays locked in between spins. Five Scatters unlock the Ultra Bonus Game, opening at 3x, in which both the Pigs of Steel protection and the Piggy Wild progress persist across every spin of the round rather than resetting.

Visually, the game keeps the same storybook setting as the earlier entries in the series but gives the three pigs a more armoured, empowered look to match the tougher premise, backed by a lively soundtrack and animation that swings between whimsical and intense. A bonus buy is available in supported regions for direct entry into one of the three rounds, though the specific costs aren't published.

With protection and Wild progress that can carry over between spins in the higher tiers, and starting multipliers that scale from 1x up to 3x depending on the trigger, Big Bad Wolf: Pigs of Steel is built around extending its Tumbling Reels sequences for as long as possible rather than relying on a single big hit.
