How accurate is the Riftbound Deck Probability calculator?

The exact mode uses hypergeometric distribution for mathematically precise results. The Monte Carlo simulation runs 10,000 iterations with a 95% confidence interval.

Does the calculator account for Riftbound's mulligan rules?

Yes. Riftbound allows swapping 0-2 cards. The calculator supports selective mulligan simulation across thousands of Monte Carlo iterations.

Can I calculate rune color probability separately?

Yes. The 12-card rune deck is modeled independently using multivariate hypergeometric distribution for dual-color joint probability.

What is the difference between exact and simulated probability?

Exact uses the hypergeometric formula for guaranteed-correct results. Simulated uses Monte Carlo sampling for complex multi-condition scenarios. Both are shown when available.

How does the Yu-Gi-Oh Deck Probability calculator work?

Enter your deck composition with card names, types, and quantities. Set win conditions (e.g., draw at least 1 Starter by turn 1), and the engine computes exact probability using hypergeometric distribution. For complex scenarios with pot cards, Monte Carlo simulation runs 10,000 iterations.

Does the calculator support pot card effects like Pot of Desires?

Yes. Mark any card in your deck as a pot card and select its effect type. Pot of Desires (banish 10, draw 2), Pot of Prosperity (draw 2), Pot of Extravagance (draw 2), and Pot of Duality (look 3, pick 1) are all supported with accurate Monte Carlo simulation.

What is the difference between going first and going second in the calculator?

Going first means you start with 5 cards and skip your first draw phase. Going second means you draw on turn 1, effectively seeing 6 cards by T1. The calculator adjusts all probabilities accordingly.

Can I calculate the probability of opening multiple specific cards at once?

Yes. Add multiple win conditions — for example, 'at least 1 Starter AND at least 2 Hand Traps'. Each condition is calculated independently, showing the exact probability for each.

What is Yu-Gi-Oh Deck Probability?

Yu-Gi-Oh Deck Probability is a free online calculator for competitive Yu-Gi-Oh! TCG players. Compute the exact probability of drawing specific cards or card types in your opening hand, analyze Yu-Gi-Oh opening hand odds across multiple conditions, and optimize your deck composition with data-driven decisions.

Unlike basic Yu-Gi-Oh draw calculators, our tool supports multi-condition analysis — calculate the odds of opening both a Starter and a Hand Trap simultaneously. The Yu-Gi-Oh probability engine uses hypergeometric distribution for exact math and Monte Carlo simulation for complex scenarios involving pot card effects.

How Yu-Gi-Oh Deck Probability Works

Enter your deck list in the Yu-Gi-Oh Deck Probability card builder. Assign each card a type — Hand Trap, Starter, Extender, Spell, or any custom label. Set your win conditions: for example, "draw at least 1 Starter AND at least 2 Hand Traps by turn 1". The Yu-Gi-Oh TCG probability engine computes each condition independently.

Toggle between going first (5 cards, no T1 draw) and going second (6 cards with T1 draw) to see how Yu-Gi-Oh draw probability changes. The turn-by-turn timeline visualizes how your Yu-Gi-Oh opening hand odds improve from T1 through T6.

Mark pot cards in your deck — Pot of Desires, Pot of Prosperity, Pot of Extravagance, or Pot of Duality — and the Monte Carlo engine simulates their actual effects: banishing, extra draws, or filtering. No more guessing how pots affect your Yu-Gi-Oh deck probability.

Yu-Gi-Oh Deck Probability FAQ

How accurate is the Yu-Gi-Oh Deck Probability calculator?

For single-condition queries without pot cards, the result is mathematically exact using the hypergeometric formula. For multi-condition or pot card scenarios, Monte Carlo simulation runs 10,000 iterations with a 95% confidence interval.

Does going first or second affect Yu-Gi-Oh draw probability?

Yes significantly. Going first means 5 cards with no turn 1 draw. Going second gives you 6 cards by T1. For a card at 3 copies in a 40-card deck, going second improves your opening odds from about 33% to 39%.

How do pot cards affect Yu-Gi-Oh Deck Probability?

Pot cards are simulated realistically via Monte Carlo. Pot of Desires banishes 10 cards face-down (your targets might be banished) then draws 2. Pot of Duality looks at 3 and picks 1 (filter effect, not raw draw). The calculator models these mechanics accurately.

Can I calculate probability for multiple conditions simultaneously?

Yes. Add multiple win conditions — each is calculated independently. For example, see the probability of opening at least 1 Starter alongside the probability of opening at least 2 Hand Traps, side by side.
