A random number from 1 to 10
Pressing Generate picks one of ten numbers (1, 2, 3, 4, 5, 6, 7, 8, 9 or 10) with an equal 1 in 10 chance each. The page draws a number when it opens, so you already have one; press Generate for the next. Want more than one? Set How many, and tick No repeats to get different numbers, for example three different numbers from 1 to 10.
Common uses for 1 to 10
- Guessing games. Think of a number from 1 to 10: the tool picks one and you guess.
- Ratings and tasks. Pick a random question number, chapter, line or student number from a short list.
- Turn order. Ask for as many numbers as there are players with No repeats on to get a random order.
- Dice stand-in. A ten-sided die numbered 1 to 10 behaves the same way. For a d6 or a d20, use the dice roller.
Repeats in a short range
With only ten possibilities, repeats arrive quickly when they are allowed. The chance that at least two of three picks match is 28%, and for five picks it is about 69.8%. Because the range is small, most people are surprised how soon a repeat shows up; it is normal for a fair generator. Turn on No repeats when you need different numbers.
For another range, use the full random number generator, or jump to 1 to 100 or 1 to 1000.
Frequently asked questions
What is the chance of each number from 1 to 10?
Exactly 1 in 10, or 10%, for every number. The generator uses rejection sampling so that no number is favoured.
Can I pick several different numbers from 1 to 10?
Yes. Set How many and tick "No repeats". You can ask for up to 10 different numbers.
How likely is a repeat in a few picks from 1 to 10?
With repeats allowed, three picks contain at least one repeat 28% of the time, and five picks about 69.8% of the time.
Is a random number from 1 to 10 the same as rolling a ten-sided die?
The odds are the same if the die is numbered 1 to 10. Some ten-sided dice are numbered 0 to 9, which is a different range.
Can I change the range?
Use the full random number generator to set any minimum and maximum, decimals and sorting.

Method notes: MDN describes crypto.getRandomValues() as returning cryptographically strong random values and says Math.random() does not provide cryptographically secure numbers. The W3C Web Cryptography API says the implementation, not the page, selects the seed. Range mapping uses rejection sampling and the Fisher-Yates shuffle, and both are unit-tested. Repeat-chance figures use the standard birthday-problem formula and are unit-tested. Everything runs in your browser. Nothing you enter or generate is sent anywhere or stored.
