Slot Summary

Dr. Walter Prescott's secret laboratory gives Madder Scientist a reason for every mechanical interruption: experiments become pick bonuses, switches create temporary Wild behavior, and individual reels can be respun for a price. Betsoft ties those choices to a 30-payline, medium-volatility game with 95.18% RTP, making this less a simple Science skin than a sequence of optional interventions around the base spin.

How It Plays

Regular wins use thirty selectable paylines. After the reels stop, the player may pay to respin one selected reel, creating a targeted decision rather than repeating the entire result.

Several special symbols lead to different outcomes, so the laboratory format is split among instant selections, Free Spins, and a separate Bonus Game instead of one dominant trigger.

Theme & Atmosphere

Science supplies the secret laboratory, experimental serum, and eccentric inventor. Betsoft names Walter Prescott as the figure attempting to turn ordinary objects into gold.

The Fantastic treatment pushes the experiments beyond conventional chemistry, while Action & Adventure and Exploration emerge through the repeated tests and unpredictable results of Prescott's inventions.

Action & Adventure Science Fantastic Exploration

Features & Win Potential

Paid Respins allow one reel to be spun again after a regular result. The additional cost depends on the chance that the selected reel can improve the outcome.

Wild and Scatter symbols lead into different feature paths. One special event creates temporary Wild behavior during Free Spins, while another symbol set activates the Bonus Game.

Free Spins Scatter Symbol Wild Symbol Respins Medium volatility 5 Reels Bonus Game RTP range 30 Paylines Paid respin 3D

Bonus & Free Spins

The Bonus Game can be triggered by beakers appearing on the first, third, and fifth reels. The player selects beakers until a collect result ends the sequence.

Free Spins begin when three Switch Scatter symbols appear. One reel then becomes Wild for a predetermined number of spins, changing substitution coverage during the feature.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (95.18%), with wins capped at its top multiplier (1,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
