Meet the Cast of Characters and Components

The lab is filled with quirky icons that follow a strict left-to-right pay structure, requiring combinations of two or three or more matching symbols. Low-paying symbols include a danger sign, tall beakers, a carrot, and a clipboard—yielding 1.2x to 1.6x the bet for five matches. Premium symbols are represented by an electric orb container, a jittery rabbit, a savvy lab assistant, and the professor himself, paying up to 20x your bet.

Wilds take the form of electric switches, appearing only on reels 2 to 4 and expanding vertically to maximize win potential. Beaker symbols—filled with glowing liquids—trigger the slot’s main feature.

Experimental Features: What Powers the Wins

Here are the mechanics behind this high-voltage experiment:

1. Expanding Wilds
   Wilds not only substitute for regular symbols but also expand to cover entire reels when they land. These only appear on reels 2, 3, and 4, amplifying your chances for reaction chain wins.
   
2. Mystery Symbols
   At the start of every spin, mystery positions are selected on each reel and replaced with a random paying symbol (excluding Beaker and Wild). These symbols sync across all reels, creating consistent possibilities for uniform wins.
   
3. Hold & Win Bonus
   Land 6 or more Beakers anywhere on the grid to initiate this scientific frenzy. You’ll receive 3 respins, and the only symbols that can land are full or empty Beakers.
   
   • Full Beakers: Contain instant cash prizes (1x–400x) or one of four jackpots:
     
     • Mini Jackpot: 10x
       
     • Minor Jackpot: 30x
       
     • Major Jackpot: 100x
       
     • Grand Jackpot: 500x
       
   • Empty Beakers: Still contribute—when the bottom row fills with any combination of Beakers, all their values are instantly collected.
     
   • Each time a new Beaker lands, the respin count resets to 3.
     

Special Beakers: Lab Enhancers in the Bonus Round

During the Hold & Win round, three special types of Beakers may appear to intensify the reaction:

• All Beaker: Absorbs the total value of every visible Beaker on the grid.
  
• Cross Beaker: Collects all values from the Beakers positioned vertically and horizontally in line with it.
  
• Extra Beaker: Boosts every visible Beaker’s value by 1x–5x the bet (excluding empty Beakers).
