Dr. Porcus

Dr. Porcus is a steampunk and alchemy-themed slot by NOTDED with an RTP of 96.5%, high volatility and a maximum win of 15,000x. The game uses a 5×3 grid with 15 paylines.

The Wild Symbol substitutes for other symbols to complete winning combinations. The Scatter Symbol triggers the bonus modes when three or more land on the reels. Expanding Wilds grow to fill entire reels during certain features, applying their multiplier across the full column. Sticky Wilds remain locked in place throughout a bonus round, retaining their individual multipliers. Multipliers are applied to winning lines, with Sticky Wilds adding their multipliers together only on lines where they contribute to a win. Wild Multipliers enhance payouts on reels where Wilds expand or stay fixed.

Sticky Formula activates when 3 Scatters land, awarding 8 Free Spins with a single Wild that sticks in place for the entire bonus round. Each sticky Wild carries its own multiplier, and multipliers combine only on winning lines containing them.

Wild Chaos triggers with 4 Scatters and grants 8 Free Spins. On each spin, the Wild expands to cover the full reel and applies a multiplier, then resets before the next spin for continuous movement through the feature.

Mad Spins begins when 5 Scatters land, providing 10 Free Spins. The Wild expands across the full reel and remains sticky throughout the bonus, with its multiplier building continuously. No Scatter retriggers occur during this mode.

Scatter Boost increases Scatter frequency before each spin at an adjusted cost, making it easier to trigger bonus features without changing the base symbol set or bonus rules.
