About this tool
Set a minimum, a maximum and how many numbers you want. Numbers come from the browser's cryptographic random source, and you can require every draw to be unique — useful for prize draws, sampling and picking a starting player.
Questions & answers
- Is the result really random?
- It uses the browser's cryptographic random generator with rejection sampling, so every value in the range is equally likely and the results are not predictable from earlier draws.
- Can I draw without repeats?
- Yes. Turn on unique values and the tool draws distinct numbers, as long as the range is large enough for the count you asked for.
- Does this tool send my data to a server?
- Runs entirely in your browser. Nothing you type is uploaded.
