How to use this random number generator

On a phone the result sits above the settings, and the main button is in the bar at the bottom of the screen.

Saved wheel lists stay in this browser, so they are there next time

1
Numbers
Set Min, Max and How many (up to 10,000). Turn on No repeats for a draw like names from a hat, and sort if you want them in order.
2
Decimals
Switch Numbers to Decimal and pick 1 to 6 places. Every value at that precision, both ends included, is equally likely.
3
Spin the wheel
Paste up to 100 names or options, one per line. Spin, and turn on Remove the winner to draw a running order.
4
Save and share
Name and save a list in this browser, or copy a share link that opens the wheel with the same list for someone else.

How it works

Why the results are fair

Three rules keep every pick unbiased: a strong source, no modulo bias, and a wheel that never decides by where it stops.

A cryptographic source

Every draw uses crypto.getRandomValues. MDN describes it as giving "cryptographically strong random values", while Math.random "does not provide cryptographically secure random numbers".

Built into every modern browser
Not Math.random
No server, nothing logged

No modulo bias

A 32-bit random value has 4,294,967,296 possibilities. That does not split evenly into 6, so plain "value mod 6" makes some faces slightly likelier. The tool throws away the last 4 values and draws again.

Keep values below 4,294,967,292
Each face then has the same count
A redraw is very rare

Winner first, then the spin

The wheel's winner is drawn with the same unbiased method before it moves. The animation is then aimed to stop inside that slice, so speed or timing can't change the result.

Every slice the same size
Every entry the same chance
Reduced motion: no long spin

For no repeats, the tool shuffles the range with a Fisher-Yates shuffle (or, for huge ranges, draws again on a repeat), so every set of numbers is equally likely. If you ask for more unique numbers than the range holds, it says so instead of guessing.

Turns and teams

Draw a full running order

Turn on Remove the winner and spin until one name is left. Each winner leaves the wheel before the next spin, so nobody is picked twice.

Share and save

Same list, any device

Save a list by name in this browser, or copy a share link. The link holds the list itself in the address, so nothing is stored on a server.

Dice odds

Odds of each total with two six-sided dice

Each die is fair, but totals are not: there are 36 equally likely pairs, and 6 of them make 7.

Total	Ways (of 36)	Chance
2	1	2.8%
3	2	5.6%
4	3	8.3%
5	4	11.1%
6	5	13.9%
7	6	16.7%
8	5	13.9%
9	4	11.1%
10	3	8.3%
11	2	5.6%
12	1	2.8%

A single die of any size gives each face the same chance: 1 in 4 on a d4, 1 in 20 on a d20. A fair coin is 1 in 2 for heads on every flip, whatever came before.

Repeats or not

With repeats vs without repeats

Ten numbers from 1 to 10, two ways. Both are fair; they answer different questions.

Like rolling a die again

10¹⁰possible results

Repeats allowed

Every number is drawn on its own, so 7 can come up twice. Use it for dice-style rolls, simulations and sampling.

Like names from a hat

10!orders, each number once

No repeats

Each number appears once, so ten from 1 to 10 is a shuffled order of all ten. Use it for raffles, seating and turn order.

Verdict: for prizes and turns, turn No repeats on. For anything that models dice or repeated trials, leave it off.

Pro tips

Pro tips for random picks

Small habits that make a draw easy to trust.

Draw in public

Share your screen or project the wheel, so everyone sees the same spin and the same result.

Check the list

Remove duplicates first: a name typed twice gets two slices and twice the chance.

Number the entries

For big raffles, number the tickets and draw numbers with No repeats instead of a giant wheel.

Save regular lists

Save your class or team once, then load it in one tap next time.

Share the setup

Send the share link before a draw so people can check their names are on the wheel.

Copy the result

Copy numbers with commas or one per line, ready for a spreadsheet.

Best of three

Flip three coins at once and go with the majority for a quick, fair call.

Keep it fun

Spin again for the next prize; recent picks stay listed so nobody loses track.

Fun and fair, not a regulated draw

The randomness is cryptographic strength, but this page keeps no audit record. For a prize draw with legal rules, such as a sweepstakes or a lottery, follow the rules and any record-keeping that apply where you run it.

Use cases

Everyday things it decides

One page, four ways to pick.

Giveaway winner

Draw an entry number or spin the wheel of entrants.

Classroom picker

Call on a student or set the presentation order.

Random teams

Spin with Remove the winner on and split as names come out.

What's for dinner

Put the options on the wheel and settle it in seconds.

Game night

Roll any mix of dice from d4 to d20 with the total.

Heads or tails

Flip a coin for kickoff, or ten for a quick experiment.

FAQ

Frequently asked questions

Quick answers on fairness, no repeats, the wheel, sharing lists, coins and dice.

Is this random number generator truly random?

It uses your browser's crypto.getRandomValues, which MDN describes as giving cryptographically strong random values from a generator seeded with enough entropy. That is far stronger than Math.random, and more than enough for games, raffles and picks.

What is modulo bias, and how does this avoid it?

A random 32-bit value has 4,294,967,296 possibilities, which don't split evenly into most ranges, so taking the remainder makes some numbers slightly likelier. This tool throws away the few leftover values and draws again (rejection sampling), so every number in your range has exactly the same chance.

How do I pick random numbers without repeats?

Turn on No repeats. Each number then appears at most once, like drawing from a hat: 10 numbers from 1 to 10 gives all ten in a random order. If you ask for more numbers than the range holds, the tool tells you it can't be done.

Is the spin the wheel result fair?

Yes. Every entry gets an equal slice. The winner is drawn with the same unbiased method before the wheel moves, and the spin is aimed to stop on that slice, so speed or timing can't change it. With reduced motion turned on, the result shows without a long spin.

Can I remove the winner from the wheel?

Yes. Turn on Remove the winner and each winner leaves the wheel before the next spin, so you can draw a full order or several prizes without picking anyone twice.

How do I save or share a wheel list?

Name and save a list to keep it in this browser (up to 12 lists). Share link copies an address that holds the list itself, so anyone who opens it gets the same wheel. Very long lists are trimmed to fit in a link.

Can it flip a coin or roll dice?

Yes. Coin flips 1 to 10 coins and counts heads and tails. Dice rolls 1 to 10 dice with 4, 6, 8, 10, 12 or 20 sides and adds up the total.

Is anything uploaded or stored?

Nothing is uploaded: every draw happens in your browser. Saved wheel lists are kept in this browser's local storage, and recent picks last for this visit only.
