Random Number Generator – Spin a Number Wheel
A random number generator picks a number from a range you choose, with every number equally likely. Set the minimum and maximum (for example 1 to 100), press "Generate & apply", and spin the number wheel to get your random number.
Quick presets cover the most common ranges – 1–10, 1–20, 1–50, 1–100, dice 1–6, digits 0–9, even numbers and tambola 1–90. Turn on Auto-remove to draw numbers without repeats, like a lottery-style draw for a class or a raffle ticket.
The Results tab keeps every number you generated, so you can copy the list when you are done. Just need 1 to 6? Use the 1–6 number wheel.
How to Generate a Random Number
Set the range
Type Min and Max in "Number generator config", or tap a preset such as 1 - 100.
Apply
Press "Generate & apply numbers". The wheel fills with every number in the range (use Interval to skip, e.g. 5, 10, 15…).
Spin
Spin the wheel to pick a number. Auto-remove gives unique numbers with no repeats.
Popular Ranges
| Range | Chance of each number | Used for |
|---|---|---|
| Random number 1–10 | 10% | Guessing games, quick choices, rating |
| Random number 1–20 | 5% | Class roll numbers, D20 rolls |
| Random number 1–50 | 2% | Seat numbers, small raffles |
| Random number 1–100 | 1% | Raffle tickets, percentages, quizzes |
| 1–90 | 1.1% | Tambola / housie |
| 0–9 | 10% | Random digits, PINs for games |
Random Numbers Without Repeats
Turn on Auto-remove winner in Customize. Each number leaves the wheel after it is picked, so the next spin can only land on numbers that have not come up yet. This is how you draw raffle tickets, assign presentation order, or pick unique questions from a numbered list. Press the reset button to put all numbers back.
How Random Are the Numbers?
Numbers come from crypto.getRandomValues with rejection sampling – the same approach used for security software – so every number in your range has exactly the same chance. Unlike Math.random(), it is not predictable from earlier results. For a large range such as 1–1,000,000 a wheel has too many slices to read, but every number still has an equal chance; the wheel simply shows a selection of labels.
