Frequently Asked Questions

Are the numbers truly random?+

They're generated by your browser's random source — statistically uniform and unpredictable for draws, games and sampling. For cryptographic keys, use dedicated security tools.

Can duplicates appear in a batch?+

Yes, each number is drawn independently by default — like rolling dice repeatedly. That's the mathematically honest behavior for most uses.

What are common uses?+

Prize draws and giveaways, random team assignment, generating test data, lottery-style picks and classroom activities.

Is there a range limit?+

Any practical range works — from coin-flip 0/1 to millions.
