Random Number Generator and Number Wheel

How to generate a random number

1. Set the range. Type the lowest and highest number, or press a quick button such as 1-10, 1-13 or 1-100. Both ends count, so 1 to 13 can give 1 or 13.
2. Choose how many. One number is the default. For several, type how many you need.
3. Press Generate. The result appears in large figures and goes into the history below it, newest first.

Once the first number is drawn, the range, the quantity and No repeats are locked so the draw stays the same from start to finish; press New draw to change them. With No repeats on, numbers drawn earlier in the same draw never come up again, just like tickets taken out of a box.

Keep No repeats on when every number must be different, as with raffle tickets or lottery-style picks. Turn it off when each number is drawn on its own, like rolling the same die again. Sort the results lists several numbers from lowest to highest, which makes them easier to read out.

The number wheel

With Spin the number wheel on, the page draws a wheel with one slice for every number in your range, up to 100 numbers, and spins it to each result. When you ask for several numbers, the wheel spins once for each of them, up to 20 spins, and the numbers appear underneath one by one. It is far more fun to watch on a projector or a stream than a figure appearing on its own. The number is drawn first and the wheel is then turned to it, so the animation never changes the result.

Turn the switch off when you want the numbers straight away, or when the range is larger than 100 numbers; then the results appear instantly without the wheel.

Prefer names to numbers? The spin wheel takes any list of names and can pick a prize in the same spin, and the random name picker chooses names from a list in one click.

Common ranges and what they are for

• 1 to 6: a single die. For more dice and totals, the dice roller handles any combination such as 3d6.
• 1 to 10: rating something, choosing a question from a list of ten, or a quick guessing game.
• 1 to 13: one card value from ace to king, or picking a player in a group of thirteen.
• 1 to 100: percentages, classroom numbers and giveaways where entrants have numbered tickets.
• 1 to 1000 and beyond: large raffles. Type any range you need, including negative numbers.

For two outcomes it is quicker to flip a coin or spin the yes or no wheel than to pick from 1 to 2.

Is it really random?

Yes. Every number comes from your browser's cryptographically secure random generator, the same source browsers use for encryption keys. The page uses rejection sampling, which throws away the few raw values that would otherwise make low numbers slightly more likely, so each number in the range has exactly the same chance. Nothing is sent to a server and nobody can tilt the result. Our fairness page explains the method.

Questions

How do I get a random number between 1 and 100?

Press 1-100 and then Generate. Each whole number from 1 to 100 has a one in a hundred chance.

Can I pick 6 numbers from 1 to 49 with no repeats?

Yes. Type 1 and 49 as the range, 6 in How many, keep No repeats on and press Generate. Turn on Sort the results to read them in order.

How is this different from Google's random number generator?

Google shows a quick tool for one number in its search results. This page adds several numbers at once, no repeats, sorting, a history and the number wheel.

Does it work with negative numbers or large ranges?

Yes. Any whole numbers between minus one billion and one billion work, and you can draw up to 1,000 numbers at a time.
