Draw a Card
Choose a deck and tap Draw a card – cards come from a fairly shuffled deck and are not put back. Below you see how likely red, an ace or a face card is next.
How it is calculated
How drawing cards works
- Choose a deck: 52 cards (ace, 2–10, jack, queen, king in four suits), 32 cards (7 to ace, as in piquet) or 54 cards with two jokers.
- Set how many cards per draw you want, e.g. 5 for a poker hand.
- Tap Draw a card. Drawn cards stay out – just like a real deck, without replacement. Reshuffle puts all cards back.
How is the deck shuffled?
The whole deck is shuffled with the Fisher–Yates algorithm. The random numbers come from the browser’s crypto.getRandomValues() (W3C Web Cryptography API) without modulo bias. Every order of the cards is therefore equally likely – unlike shuffling by hand, where cards often stay together in clumps.
The odds table
Without replacement the probability changes with every card: chance = matching cards left ÷ cards left. In a full 52-card deck the chance of an ace is 4/52 ≈ 7.7%; if two aces are already out and 40 cards remain, it is 2/40 = 5%. The table recalculates after every draw – handy for practising probability.
Notes
- For magic tricks, party games, classroom probability or making a draw when no deck is at hand.
- The deck is not saved and nothing is sent; reloading the page reshuffles.
- The tool is not intended for gambling for money.
Frequently asked questions
How do I draw a random playing card online?
Choose a deck and tap “Draw a card”. The card comes from a fairly shuffled deck; further cards follow without replacement until you reshuffle.
What are the odds of drawing an ace?
From a full 52-card deck 4 in 52, about 7.7%. From a 32-card deck 4 in 32 = 12.5%. After each draw the table shows the current odds.
Is the shuffle really random?
Yes. The deck is shuffled with the Fisher–Yates algorithm and the browser’s cryptographic random numbers – every order is equally likely.
Can I draw several cards at once?
Yes, 2, 3, 5 or 7 cards per draw, e.g. for a poker hand or dealing. If fewer cards are left, the rest are drawn.
What is in a 32-card deck?
Each suit has 7, 8, 9, 10, jack, queen, king and ace – the deck used for piquet, belote and skat. The 52-card deck adds 2 to 6.
