How it works

Each number is drawn uniformly at random from [Minimum, Maximum] using the browser's cryptographically secure random source
Example

Generating 5 unique numbers between 1 and 100 might produce something like: 7, 23, 45, 68, 91 - a different result every time you click generate.

Step-by-step guide

  1. Set your minimum and maximum range.
  2. Choose how many numbers you want, and whether repeats are allowed.
  3. Click "Generate" for a fresh result.

When to allow repeats, and when not to

Allowing repeats makes sense when each number represents an independent event, like simulating multiple dice rolls or lottery-style number draws that could plausibly repeat. Disallowing repeats is the right choice when you're picking distinct items from a set - like randomly selecting a handful of unique raffle winners from a numbered pool, or shuffling a specific range of values where each number should appear at most once.

Common mistakes

Requesting more unique numbers than the range can hold - asking for 20 unique numbers between 1 and 10 is mathematically impossible, and the tool will flag this rather than give a misleading result.
Using "allow repeats" when you actually needed distinct results, like drawing multiple different raffle winners - double check the repeat setting matches what you actually need.

Frequently asked questions

Is this suitable for a real drawing or giveaway?

It uses a cryptographically secure random source, suitable for informal drawings and giveaways. For a legally regulated sweepstakes or contest with significant prizes, check your specific jurisdiction's requirements, which may call for additional documentation or a specific certified process.

Can the minimum or maximum be negative?

Yes - enter a negative minimum (like -50) to generate numbers that can fall below zero, useful for certain simulations or games.

What's the maximum count of numbers I can generate at once?

This tool caps at 50 numbers per generation to keep the display manageable - run it again if you need more.
