About random numbers from 1 to 10
Need someone to “pick a number between 1 and 10”? This generator does it fairly and instantly. Every number from 1 to 10 has exactly a 1 in 10 (10%) chance on each roll, and because results come from your browser’s cryptographically secure crypto.getRandomValues(), there is no pattern to guess and no bias toward 7 — the number people pick most often when asked to choose “randomly” themselves.
A 1–10 range is ideal for quick decisions and small groups: choosing which of ten tasks to tackle first, assigning a speaking order to ten team members, scoring something on a 1–10 scale for a blind test, or running a guessing game with kids. Each roll is independent, so the same number can come up twice in a row with a 10% chance — that is randomness working correctly, not a glitch.
Repeats show up faster than most people expect. After just 5 rolls there is about a 70% chance at least one number has already appeared twice. If you need every number exactly once — for example to set a turn order for 10 players — switch on Draw mode (no repeats), which deals 1 through 10 in a random order until all ten are used.
Frequently Asked Questions
What is the probability of getting a specific number from 1 to 10?↓
Exactly 10% (1 in 10) on every roll. Rolls are independent, so previous results do not change the odds of the next one.
Why does the same number sometimes come up twice in a row?↓
Each roll is independent, so there is a 10% chance the next number matches the last one. Use Draw mode if you want no repeats until all ten numbers have been drawn.
How do I get a random order of the numbers 1 to 10?↓
Use Draw mode and press Draw (or Space) ten times, or use Multiple numbers with Count 10 and “No duplicates” switched on to get a full shuffled list at once.
