Dice and a number range producing a random number

How the numbers are chosen

Each number is drawn uniformly from the whole range, including both ends, using your browser’s cryptographic random generator with rejection sampling, which avoids the slight bias of the common “modulo” shortcut. With “No repeats” on, numbers already drawn are skipped, like drawing balls from a bag.

Handy uses

  • Pick a raffle winner by numbering entries and drawing one number.
  • Roll dice or choose a random item: set 1 to 6 or 1 to the number of items.
  • Draw several unique numbers for a lottery-style pick (for example 6 numbers from 1 to 49).

Frequently asked questions

Are the numbers truly random?

They come from your browser’s cryptographically secure generator, which is suitable for draws and games. It is not a physical random source, but it is unpredictable for all practical purposes.

Are the minimum and maximum included?

Yes, both ends of the range can be drawn.

How do I pick unique numbers?

Tick “No repeats”. The count cannot exceed the number of values in the range.

Can I use negative numbers?

Yes. Enter a negative minimum such as -50.
