Random Number Generator

How This Random Number Generator Works

The generator uses your browser's built-in random number source to pick whole numbers uniformly between the minimum and maximum you enter (both included). If you ask for more than one number and turn off repeats, it keeps generating until it has that many unique values, so the count you request can't exceed the number of whole numbers available in your chosen range.

Common Uses

• Picking a winner from a numbered list of entries
• Choosing lottery-style number sets
• Randomly sampling data for statistics or testing
• Games, dice rolls, and classroom activities
