How Random Number Generators Work

A Random Number Generator (RNG) is a system designed to produce a sequence of numbers that lack any pattern. This tool uses the cryptographic random generator built into your browser.

Common Uses

Lotteries & Raffles: Picking winners fairly from a pool of ticket numbers.
Research: Selecting random participants for surveys or clinical trials.
Education: Generating math problems or creating randomized seating charts.
Gaming: Rolling dice, shuffling cards, or determining loot drops.

Frequently Asked Questions

Can I generate negative numbers?

Yes! Simply enter a negative value in the "Min Value" field (e.g., -100) and set your "Max Value" accordingly.

Is it truly random?

For everyday purposes, yes. We use the cryptographic capabilities of modern web browsers when available to ensure high-quality randomness.

Is there a limit to how many numbers I can generate?

To keep the browser responsive, we recommend generating up to 1,000 numbers at a time. For larger datasets, it's better to generate in batches.

HOW TO USE

Choose random numbers

Set integer minimum, maximum and quantity. Enable unique values or sorting when needed.

Example

Unique sorted values from 1 to 10 with quantity 10 produce each integer 1 through 10 once.

Before you use the result

The range must fit the supported 32-bit span. This is not an audited lottery or gambling system.
