How this Yu-Gi-Oh! Opening Hand Probability Calculator works
The hypergeometric distribution samples cards without replacement from the deck. Probability depends on deck size, copies of the target, hand size and selected target-count rule.
Important: This calculator assumes a random, well-shuffled deck and does not model mulligans, search effects, drawing first/second rules beyond the entered hand size, or card dependencies.
What assumptions should I verify?
Verify every entered quantity, rate, unit, product specification and local requirement before relying on the estimate. U.S. conventions are primary where location matters.
Is information sent anywhere?
No. Calculations run locally in the browser and this calculator sends no entered information to a remote service.
