Your result will appear here.

Example ranges

  • Single pick: Draw one number between 1 and 100.
  • Classroom activity: Draw several numbers without repeats to assign turn order.
  • Numbered tickets: Generate a batch from the range printed on your tickets.

How the draw works

When available, the tool uses the browser’s cryptographic random number generator; otherwise it falls back to the standard pseudorandom generator. This is for everyday draws, not an auditable lottery or security-sensitive selection.

Limits and privacy

The tool runs locally in your browser and does not send the range or results to the server. The range may span at most 1,000,000 integers; a draw can return up to 10,000 numbers. With repeats disabled, the requested quantity cannot exceed the range.

Frequently asked questions

Can I draw several numbers?

Yes. Set the quantity and choose whether repeated values are allowed.

Why did the tool swap my range?

If the minimum is larger than the maximum, the values are reversed to form a valid range.

Is this suitable for a lottery?

It is a simple browser tool, not a certified or independently audited lottery system.
