A random number generator picks a whole number from a range you specify, with every value in that range equally likely to appear.
This generator produces one or more random whole numbers between a minimum and maximum value you choose.
How it works
Enter a minimum value, a maximum value, and how many numbers you want. The generator uses a cryptographically secure random number source to pick each number independently and uniformly from that range.
- Enter minimum value.
- Enter maximum value.
- Enter how many numbers.

Examples
Picking a raffle winner
Generating one random number between 1 and 100 gives every ticket in that range an equal chance of being picked.
Simulating dice rolls
Generating 10 random numbers between 1 and 6 simulates rolling a six-sided die ten times.
Who should use it
- Picking a random winner from a numbered list of entries.
- Generating sample data or simulating random events like dice rolls.
Industry applications
- Games, raffles, and giveaways
- Statistics education and simulations
Advantages
- Uses a cryptographically secure random source for genuinely unpredictable results.
- Supports any range, including negative numbers, and up to 100 numbers at once.
Limitations
- Does not offer a "no duplicates" mode — numbers are generated independently.
Common mistakes to avoid
- Setting the minimum value higher than the maximum value, which isn't a valid range.
- Expecting no repeats when generating multiple numbers, when duplicates are possible by design.
Best practices
- If you need unique numbers with no repeats, generate a few extra and discard any duplicates.
Tips
- For a fair raffle or lottery draw, generate exactly one number at a time rather than a batch, to keep the process simple to verify.
