How this tool works
Each draw uses Math.random() to select an integer uniformly from the inclusive range. Unique mode rejects values already selected.
Example
Generate five unique integers from 1 through 100 for a classroom draw or test-data sample.
Common questions
Is this cryptographically secure randomness?
No. Math.random() is suitable for casual selection and test data, not keys, lotteries with legal requirements or security-sensitive use.
Why can unique mode fail?
You cannot request more unique integers than exist in the selected inclusive range.
