Features that amplify the terror and the wins

Cascading Reels

Winning symbols disappear and new ones drop into place, generating chain reactions for continuous wins.

Expanding Multiplier Wilds

The mad scientist wild only appears on reels 2 and 4. Once triggered, it expands across the reel and carries three random multipliers, ranging from combinations like ×1/×2/×3 up to ×10/×15/×25. Each cascade collects the next multiplier sequentially, adding to a global win multiplier that persists until the cascade ends.

Free Spins Feature

Landing 3+ Scatter symbols triggers 15 Free Spins, with +2 spins added per extra Scatter. In Free Spins, the global multiplier continues to grow without resetting, delivering a powerful escalation of win potential. Retriggers are also available by landing additional Scatters.

Bonus Buy Option

Available in many regions. Players can instantly enter the Free Spins mode by purchasing it for 75× their bet.
