Random Number Generator Online for Tests and Games

Raffles, A/B sampling, and QA fixtures all need unbiased random integers. A browser random number generator beats “pick a number in my head” and keeps the range explicit.

How to generate random numbers

Set the minimum and maximum in ToolVera’s Random Number Generator, generate, and copy the result into your sheet, script, or game rules.

1. Open Random Number Generator.
2. Set the inclusive minimum and maximum.
3. Generate one or more random integers.
4. Copy results into your workflow.
5. For unique IDs instead of small integers, use UUID Generator.

Tips for fair draws and tests

Publish the range before drawing so participants trust the process. Avoid reusing a single draw for multiple decisions. Seed large test datasets with UUIDs or passwords when integers are not enough — see UUID Generator and Password Generator.
