Frequently asked questions
Is this random number generator truly random?
It uses your browser's built-in Math.random(), which is pseudo-random and suitable for games, giveaways, and everyday decisions - but not for cryptographic or security purposes.
Is this the same as asking Google to generate a random number?
Yes, functionally - Google's search results include a built-in random number generator for quick use, and this calculator does the same thing with a dedicated page, plus the option to set a custom range and generate multiple numbers at once.
Can I generate multiple random numbers at once?
Yes - set 'how many numbers' to any value up to 50 to generate a list of random numbers within your chosen range in one click.
Can I exclude specific numbers from the random range?
This calculator generates uniformly from the full range you specify (minimum to maximum); to exclude specific values, generate a number and simply re-roll if it matches an excluded value, or narrow the range if the excluded values are all at one end.
Is a 'randomness generator' the same as this random number generator?
Yes - "randomness generator" is just another way of describing a tool that produces random numbers, which is exactly what this calculator does within whatever range and count you set.
Is an 'integer random generator' different from this tool?
No - this calculator already generates whole numbers (integers) within your chosen range by default, so an "integer random generator" search is asking for exactly what this tool provides.
Can I use this for a raffle or giveaway drawing?
Yes - this generator is well-suited for informal drawings like picking a raffle winner or random giveaway entry from a numbered list. For anything with legal or regulatory requirements around fairness (like a licensed lottery), use a certified random number source instead.
