How It Works

The Hero Roulette calculator uses probability theory to estimate your rewards:

  • Expected Value: The average number of items you'll receive over many attempts
  • 95% Confidence Range: In 95% of cases, your actual results will fall within this range
  • Standard Deviation: Measures how much variation to expect from the average

Note: These are statistical estimates. Actual results may vary due to random chance.
