Lab Rat

Lab Rat is an alchemy and sci-fi themed slot by LUDEXA INTERACTIVE with an RTP of 96%, high volatility and a maximum win of 10,000x. The game uses a 6×5 grid with cluster pays, where five or more matching symbols connected horizontally or vertically form a win. Cascading reels drop new symbols after each win, keeping the action flowing across consecutive cascade chains.

The Mutation feature triggers when the X symbol lands in base play. It upgrades the lowest winning cluster on the grid, transforming those symbols into higher-value tiers before the cascade continues. This mechanic can activate multiple times during a single spin's cascade sequence.

Free Spins activate when four or more Scatter symbols land in a single spin, awarding 12 spins. During the feature, multiplier symbols can appear on the reels, and winning squares build multipliers across the board over time. Landing three or more Scatter symbols during Free Spins grants 5 additional spins, allowing the feature to extend and accumulate more multiplier coverage.

Super Free Spins costs 250x the bet and maintains the cascading multiplier active without resetting between individual spins. The grid begins boosted, with every column starting at 2x multiplier, enabling repeated hits to build stronger board positions throughout the feature.

Mutation Mayhem costs 3x the bet and makes the X symbol appear on every spin without being consumed. Instead of upgrading only the lowest winning cluster, it upgrades all winning clusters in a single spin, delivering broader mutation coverage and a faster pace.
