About Random Number Generator

Use a random number generator for a quick choice, classroom example or non-critical selection. Enter the range boundaries and understand that this utility is not a certified lottery or security randomness service.

How to use Random Number Generator

  1. Enter the smallest allowed number.
  2. Enter the largest allowed number.
  3. Generate a value and check that it falls within the requested range.
  4. Generate again if you need another independent choice.
  5. For prizes, regulated draws or security tasks, use a trusted audited system instead.

Fairness and limits

The numbers are random enough for classroom use, games, picking a turn or choosing a sample. Do not use the tool for gambling, for regulated prize draws or for anything that needs a record that others can audit. For a public giveaway, say the rules first and keep a screenshot of the result.

Frequently asked questions

Can I get several random numbers without repeats?

Yes. Set the smallest and largest number, choose how many numbers you want (1 to 10), tick No repeated numbers and press Generate numbers. The range must hold enough different numbers.

Can the same number appear twice?

Yes. Generate a fresh result does not automatically exclude numbers previously produced.

Is this suitable for a lottery drawing?

No. Use an audited and transparent process designed for regulated or prize-based draws.

How do I pick 3 different numbers from 1 to 50?

Set Minimum 1, Maximum 50, How many numbers 3, and tick No repeated numbers.
