Frequently Asked Questions

Are these numbers truly random?

Our generator uses JavaScript's Math.random() function, which produces pseudo-random numbers. While not cryptographically secure, these numbers are sufficiently random for games, simulations, and general use. For cryptographic applications, use a dedicated crypto library.

What does "unique numbers only" mean?

When enabled, the generator ensures no number appears more than once in the results. This is useful for lottery numbers, random selections without replacement, or when you need distinct values. Note that this limits the maximum count to the range size.

Can I generate negative numbers?

Yes! Simply set a negative minimum value. For example, set minimum to -100 and maximum to 100 to generate random numbers between -100 and 100.

What's the maximum number of values I can generate?

You can generate up to 1000 numbers at once. If you need more, generate multiple batches. The unique numbers option is limited by the range size (e.g., if range is 1-100, you can only generate 100 unique numbers).

How can I use this for lottery numbers?

Set the range to match your lottery (e.g., 1-49 for UK National Lottery), enable "unique numbers only", and set the count to the number of balls drawn. Generate multiple sets to increase your options!
