This critical phase establishes the mathematical foundation and operational parameters for your slot simulation. Proper configuration ensures accurate results and meaningful analysis.

1.1 Reel Strips Configuration (Mathematical Foundation)​

Core Mathematical Parameters:

  • Number Of Unique Symbols (Recommended: 8-12)

    • Purpose: Defines the symbol set size, directly impacting game volatility and mathematical complexity
    • Low Values (3-6): Creates high volatility with frequent large wins but lower hit frequency
    • Medium Values (7-10): Provides balanced gameplay with moderate volatility and consistent hit rates
    • High Values (11-15): Results in low volatility with frequent small wins and high hit frequency
    • Mathematical Impact: Affects RTP calculations, win frequency, and overall game balance

  • Weight Formula (Default: "exp(-x / 15)")

    • Purpose: Mathematical expression controlling symbol probability distribution
    • Common Formulas:
      • exp(-x / 10): High volatility, exponential decay favoring low symbols
      • exp(-x / 15): Balanced volatility, moderate exponential decay
      • exp(-x / 20): Lower volatility, gentle exponential decay
      • 1 / (x + 1): Linear decay, very predictable distribution
      • x^(-1.5): Power law distribution, mathematical elegance
    • Custom Formulas: Support for complex expressions with multiple variables and functions

  • Column Size (Standard: 5, Range: 3-10)

    • 3 Columns: Classic slot configuration, simple mathematics, limited winning potential
