How random are these numbers?

Numbers are generated using your browser's random number source, providing a uniform distribution across your chosen range.

Can I generate negative numbers?

Yes — set a negative minimum value to include negative numbers in the range.

What happens if I disallow duplicates but the range is too small?

If the range can't provide enough unique values for the requested quantity, the tool falls back to allowing duplicates for that batch.

Is my generated data sent anywhere?

No — everything is generated entirely in your browser.

Can I generate more than 100 numbers at once?

The tool is capped at 100 per generation — run it again for more.

Is this suitable for a real lottery drawing?

It provides a fair, unbiased random draw, but check any applicable rules or regulations for official lottery or raffle drawings.
