Example Uses
- Raffles & Competitions: Set the min to 1 and the max to the total number of tickets. Turn off "Allow Duplicates" to pick multiple distinct winners without replacement.
- Random Audits: Enter your total number of employees or transactions and generate a subset of unique numbers for a random quality check.
- Seeded Giveaways: Use a publicly announced time seed (e.g., "Giveaway_2026") so your audience can independently verify the results are fair.
Frequently asked questions
How does the random number generator work?
If you don't provide a seed, we use true randomness generated by the browser to ensure unpredictable results. This is perfect for everyday use like selecting a raffle winner.
What is a seed and why would I use it?
A seed is a starting point for the random number generator. If you use the same seed with the same settings, you will always get the exact same sequence of random numbers. This is useful for verifiable giveaways or testing.
Can I generate numbers without duplicates?
Yes. By default, the generator allows duplicates. If you turn off 'Allow Duplicates', every generated number will be unique. Note that your range (Maximum - Minimum) must be large enough to provide the requested count of unique numbers.
