Frequently Asked Questions
Are the generated numbers truly random?
Yes! We use your browser's crypto.getRandomValues() API. This is cryptographically secure randomness, not pseudo-random. Every number in the range has equal probability.
How is it different from Math.random()?
Math.random() is a pseudo-random (PRNG) algorithm whose output is theoretically predictable. crypto.getRandomValues() is fed by the OS hardware entropy source — the same security level used in banking and military systems.
Can the same number appear more than once?
Yes, in batch generation the same number can repeat. Each generation is independent and unaffected by previous results. This is a natural property of true randomness.
What's the maximum number I can generate at once?
Up to 50 numbers per click. Click again if you need more. There is no usage limit.
Can I generate negative numbers?
Yes! Enter a negative minimum value. For example, you can generate random numbers between -100 and 100.
Can I use this to pick lottery numbers?
Yes! Set Min: 1, Max: 49 (for numeric lottery) or 1–90 and generate 6 numbers. You may need to check for duplicates manually. Alternatively, use WheelSpinGo to put your numbers on a wheel and spin them in order.
