ComboStats

Estimate the probability of drawing success from a population (without replacement) using ComboStats! Instead of using formulas, this app draws A LOT of samples to estimate the probability of success.

This website is ideal when the probability formula for calculating success becomes very intricate. Thus this webiste is perfect for calculating the probability of complex starting hands in TCGs like Yu-Gi-Oh! and Magic: The Gathering. Therefore it uses terms like "Deck“ instead of "Population“, "Combos“ instead of "Successes“ and "Bricks“ instead of "Failures“ to better suit the intended use case.

Follow these steps to use the app:

  1. Build the population/deck.
  2. Assign the scenarios/combos that make success occur.
  3. If you want you can add scenarios that make a failure occur.
  4. Estimate the probability of success!
