Free Random Number Picker

Useful for raffles, picking a winner from a numbered list, choosing a random sample, or any situation needing an unbiased random pick from a range. The "no duplicates" option is essential when picking multiple winners from the same pool.

Worked Example

Example: Range 1-100, pick 5 unique numbers: 23, 67, 8, 91, 45.

Method

Uses Math.random() scaled to your range; for unique picks, generated numbers are tracked in a Set and re-rolled on collision.
