Frequently asked questions
Are the numbers truly random?
They are made with your browser’s cryptographic random generator (crypto.getRandomValues) and a method that gives every number in the range exactly the same chance, without the small bias that a simple remainder calculation causes. Nothing is sent to a server.
Can the same number appear twice?
Yes, by default every number is drawn independently, so repeats can happen, just like rolling a die several times. Tick “No repeats” to get different numbers; then you cannot ask for more numbers than the range contains.
What are the limits?
Whole numbers from −1,000,000,000 to 1,000,000,000, and up to 1,000 numbers at once. The minimum must not be larger than the maximum.
Can I use it for a raffle or lottery draw?
Yes, for example to draw a ticket number between 1 and 500. To pick a name from a list instead, use Spin the Wheel.
