Frequently Asked Questions

Find Quick Answers

What formula does this calculator use?

It uses the hypergeometric distribution formula, which is the mathematically correct way to calculate drawing probabilities from a finite deck without replacement.

What's a typical Yu-Gi-Oh! deck size?

Most competitive Yu-Gi-Oh! decks are 40 cards (minimum), but some run up to 60 cards. The calculator works with any deck size from 1 to 100 cards.

How many copies of a card can I have in my deck?

In Yu-Gi-Oh!, you can have up to 3 copies of most cards in your Main Deck, Extra Deck, and Side Deck combined (with some banned/limited exceptions).

Why is the probability different from simple percentage?

Because cards aren't replaced after drawing, the probability changes with each draw. The hypergeometric formula accounts for this, unlike simple percentage calculations.
