How random is this card generator?
Every shuffle runs the Fisher–Yates algorithm fed by your browser’s cryptographic random source (crypto.getRandomValues), not the weaker Math.random. Fisher–Yates walks the deck from the last card to the first, swapping each position with a uniformly chosen earlier position — a classic result proves this gives every one of the 52! possible orders exactly the same probability. And 52! is enormous:
52! = 80,658,175,170,943,878,571,660,636,856,403,766,975,289,505,440,883,277,824,000,000,000,000 (about 8.07 × 1067).
For perspective, that is far more than the number of atoms in the observable universe. Every time you press “Shuffle deck”, you almost certainly create an ordering of cards that has never existed before in the history of the world — and drawing “without replacement” then deals from that unique order exactly like a physical deck.
Single-draw probabilities
On a fresh 52-card deck, every card is equally likely. These are the odds the live panel starts from before any card is drawn:
| Event | Fraction | Probability |
|---|---|---|
| One specific card (e.g. Ace of Spades) | 1 / 52 | 1.9231% |
| Any Ace | 4 / 52 | 7.6923% |
| Any Heart ♥ | 13 / 52 | 25.0000% |
| Any face card (J, Q, K) | 12 / 52 | 23.0769% |
| Any red card | 26 / 52 | 50.0000% |
| Any black card | 26 / 52 | 50.0000% |
5-card hand odds (poker reference)
There are C(52,5) = 2,598,960 possible 5-card hands. Deal yourself five cards with this generator and these are the exact odds of what you are holding:
| Hand | Combinations | Reduced odds | Probability |
|---|---|---|---|
| Royal flush | 4 | 1 / 649,740 | 0.000154% |
| Straight flush | 36 | 3 / 216,580 | 0.001385% |
| Four of a kind | 624 | 1 / 4,165 | 0.024010% |
| Full house | 3,744 | 6 / 4,165 | 0.144058% |
| Flush | 5,108 | 1,277 / 649,740 | 0.196540% |
| Straight | 10,200 | 5 / 1,274 | 0.392465% |
| Three of a kind | 54,912 | 88 / 4,165 | 2.112845% |
| Two pair | 123,552 | 198 / 4,165 | 4.753902% |
| One pair | 1,098,240 | 352 / 833 | 42.256903% |
| High card (nothing) | 1,302,540 | 1,277 / 2,548 | 50.117739% |
Worked examples
Example 1 — Drawing the Ace of Spades. A fresh deck has 52 equally likely cards and exactly 1 is the Ace of Spades, so P = 1/52 ≈ 1.9231%. After you draw it (without replacement), the chance of drawing it again from the same deck drops to 0 — which is why the live odds panel updates after every draw.
Example 2 — Being dealt a flush. Choose the suit (4 ways), then choose 5 ranks from its 13: 4 × C(13,5) = 4 × 1,287 = 5,148 same-suit hands. Subtract the 40 straight flushes (10 sequences × 4 suits, royal included) to avoid double counting: 5,148 − 40 = 5,108. Divide by all possible hands: 5,108 / 2,598,960 ≈ 0.196540%, about 1 in 509 deals.
Example 3 — At least one Ace in 5 cards. Count the complement (no aces): choose all 5 from the 48 non-aces, C(48,5) = 1,712,304. So P(no ace) = 1,712,304 / 2,598,960 ≈ 65.8842%, and P(at least one ace) = 1 − 0.658842 = 886,656 / 2,598,960 ≈ 34.1158%. More than a third of 5-card hands contain an ace — try dealing a few hands above and see.
What people use it for
- Magic tricks — prediction effects and “name any card” reveals; use the seed box to rehearse a fixed sequence before performing.
- Board-game nights — no physical deck at hand? Draw roles, turn order, or random events from a virtual deck.
- Teaching probability — demonstrate without-replacement draws live: deal 5 cards, watch the odds panel move, then verify the class’s hand against the reference table.
- Decisions and draws — settle “who goes first” or pick a random winner fairly, with the history log as the audit trail.
- Game prototyping — designers testing card mechanics can exclude suits or ranks to simulate custom decks before printing anything.
Note: this is a playing-card generator — ranks 2 through Ace across hearts, diamonds, clubs, and spades, plus optional jokers. If you are looking for random passwords, PINs, or coupon codes, that is a different kind of generator (a random string/code tool), not this one.

Practical tips
- Keep without replacement on for anything imitating a real deck — it is the only mode where “the Ace of Spades already came out” is true.
- Dealing a full 52-card sequence? Draw 52 at once, or draw in chunks — the deck only reshuffles when you press the button.
- For classroom demos, set a seed (e.g. 42), deal the “surprising” hand once, then re-enter the seed to replay it exactly while you explain the math.
- Excluded a suit and the odds look wrong? Check the deck-size indicator — the panel always divides by the cards actually in your custom deck.
- Jokers dilute every rank probability: with 2 jokers, the Ace of Spades is 1/54 ≈ 1.8519%, not 1/52.
Random card generator — FAQs
How random is this card generator, really?
Every draw uses your browser’s cryptographic random number generator (crypto.getRandomValues) feeding the Fisher–Yates shuffle — the same algorithm casinos and statistical software use because it gives every permutation of the deck exactly equal probability. A 52-card deck has 52! = 80,658,175,170,943,878,571,660,636,856,403,766,975,289,505,440,883,277,824,000,000,000,000 possible orders (about 8.07 × 10⁶⁷), so no two shuffles in human history have ever repeated, and yours will not either.
Can I draw several cards without getting duplicates?
Yes — that is the default “without replacement” mode, which works exactly like a physical deck: each drawn card is removed, so the same card can never appear twice in one deck. Set “Draw how many” to 5 and you get a genuine 5-card hand. Switch to “with replacement” only if you want every draw to come from a full 52-card deck, where repeats are possible.
How do I exclude a suit, or remove the face cards?
Use the Custom deck panel above the draw button. Toggle any of the four suits off (for example, play with hearts and diamonds only) and toggle the Number cards (2–10), Face cards (J/Q/K), and Aces groups independently. The deck-size indicator updates live — hearts plus diamonds with aces only is a 20-card deck — and the probability panel recalculates every odd against the deck you actually built.
Can I add jokers to the deck?
Yes. The joker selector adds 0, 1, or 2 jokers (one red ★, one black ★) to whatever custom deck you configured, exactly like slipping jokers into a physical pack. A standard deck with 2 jokers becomes a 54-card deck, and the live odds panel accounts for them: jokers are neither red nor black for suit odds, and they dilute every rank probability slightly.
What is the probability of drawing a specific card, like the Ace of Spades?
Exactly 1 in 52, about 1.9231%. All 52 cards are equally likely on a fresh shuffle: one favorable outcome out of 52 possible. Related single-draw odds from a full deck: any Ace 4/52 ≈ 7.6923%, any Heart 13/52 = 25%, any face card (J/Q/K) 12/52 ≈ 23.0769%, and any red card 26/52 = 50%. Watch these numbers change live in the odds panel as cards leave the deck.
What are the odds of being dealt a flush or a royal flush in 5 cards?
Out of C(52,5) = 2,598,960 possible 5-card hands: a royal flush has 4 combinations (1 in 649,740, ≈ 0.000154%), a straight flush 36 (≈ 0.001385%), four of a kind 624 (≈ 0.024010%), a full house 3,744 (≈ 0.144058%), a flush 5,108 (≈ 0.196540%, about 1 in 509), a straight 10,200 (≈ 0.392465%), three of a kind 54,912 (≈ 2.112845%), two pair 123,552 (≈ 4.753902%), one pair 1,098,240 (≈ 42.256903%), and high card 1,302,540 (≈ 50.117739%). The full table with reduced fractions is in the reference section above.
What is the difference between drawing with and without replacement?
Without replacement, drawn cards stay out of the deck — like dealing from a real pack — so probabilities shift after every draw (after the Ace of Spades leaves, no Ace of Spades can come next). With replacement, each drawn card is conceptually returned and the deck reshuffled, so every draw faces identical odds (the Ace of Spades is always 1/52). Use without replacement for card games and realism; use with replacement for repeated independent trials.
Can I use this generator for magic tricks?
Absolutely — magicians use random draws for prediction effects, “think of a card” reveals, and forcing setups. Draw with replacement when a spectator names a card freely (every card stays possible every time), and use without replacement when the trick needs each card to appear at most once. The flip animation reads well on stage or on camera, and the optional seed box lets you rehearse a trick with a fixed, repeatable sequence before performing it live.
Can I reproduce the same draw sequence, for example when teaching?
Yes. Enter any whole number in the Seed box before shuffling and the generator switches from cryptographic randomness to a seeded stream, so the same seed plus the same deck settings always produces the identical shuffle and draw order. Teachers use this to replay a “surprising” draw in front of a class, and developers use it to verify game logic against a fixed deck.
Is this a random code or password generator?
No — this tool draws playing cards (ranks 2–A across hearts, diamonds, clubs, and spades, plus optional jokers). If you need random passwords, PINs, or coupon codes, you want a random string/code generator instead, which is a different kind of tool with a different alphabet. Everything here is about decks, suits, and draw odds.
Does the deck reshuffle automatically when it runs out?
No, deliberately. When fewer cards remain than you asked to draw, the tool tells you exactly how many are left instead of silently reshuffling — a silent reshuffle would corrupt the without-replacement odds the probability panel is showing you. Press “Shuffle deck” whenever you want a fresh, fully random deck; your draw history is kept so the session stays auditable.
Is my draw history sent to a server?
No. Everything runs 100% in your browser with JavaScript: the shuffle, the draws, the odds math, and the history log never leave your device. There is no account, no signup, and nothing to download. You can disconnect from the internet after the page loads and keep drawing cards.
Fair-play note. Every shuffle is equally likely and no card is luckier than another — that is the whole point of uniform randomness. Use the history log to settle disputes about what was drawn. Probabilities computed from exact combinatorics (C(52,5) = 2,598,960). 100% client-side: no data leaves your browser.
