LeadStone

LeadStone is a fantasy steampunk alchemy slot by Superflip Gaming with an RTP of 96.05%, high volatility and a maximum win of 20,000x. The game uses a 6x6 grid with cluster pays and pay anywhere mechanics, landing winning combinations when matching symbols touch horizontally or vertically.

The SuperFlip system activates each round, flipping the win multiplier, symbol layout or board state without ever lowering results. Giant symbols appear at the start or end of rounds in 2x2, 3x3 or 4x4 sizes, appearing as either Reagent or Wild types and feeding the Win Multiplier.

The Golden Rose lands with 2 to 5 petals, triggering a multiplier up to x1000. Each avalanche removes one petal and adds to the multiplier value. The Philosophical Egg requires 2, 3 or 5 cascades to mature, with its shell opening progressively per avalanche until a phoenix emerges and transfers the accumulated multiplier to the Win Multiplier. An unprogressed Philosophical Egg pays nothing.

Three Bonus Ravens trigger 10 Free Spins, while two Bonus Ravens plus a Super Bonus trigger 10 Super Free Spins. The Win Multiplier carries across all spins in both modes. Extra ravens landing during Free Spins add additional spins or upgrade the active feature.

Flip Boost mode increases the chance of triggering flips and feature symbols, remaining active until manually switched off. Giant Reagent mode guarantees a giant reagent block that adds to the multiplier before wins are calculated, staying sticky until the avalanche ends. Giant Wild mode guarantees a giant wild with a multiplier up to x1000, with wild cells counting towards every reagent cluster simultaneously.

Mystery mode resolves before reagents land, offering a 50% chance of Super Free Spins or 50% chance of nothing. Super Free Spins begin each spin with either a Giant Reagent or Giant Wild, with the Win Multiplier carrying across all ten spins.
