Frequently Asked Questions
Are the numbers truly random?
Yes, our generator uses JavaScript's cryptographically secure random number generator (crypto.getRandomValues()), which produces statistically random results suitable for most applications including security-sensitive uses. These are not predictable or reproducible, ensuring genuine randomness.
What's the difference between unique and non-unique numbers?
Unique numbers (no duplicates) means each generated number is different - perfect for lottery picks or raffles. Non-unique allows the same number to appear multiple times - useful for simulations or when repetition doesn't matter. For unique numbers, your range must be large enough to accommodate the quantity requested.
Can I generate negative random numbers?
Yes, simply set your minimum value to a negative number. For example, minimum -100 and maximum 100 will generate random numbers in that range including negative values, zero, and positive values.
What's the maximum range I can use?
You can use any integer range from negative to positive billions. However, for unique numbers, the range must be at least as large as the quantity of numbers you're generating. For example, you can't generate 10 unique numbers in a range of only 5 numbers.
How do I use this for lottery number generation?
Set your range to match your lottery (e.g., 1-49 for many lotteries), set quantity to how many numbers needed (usually 6), enable unique numbers so you don't get duplicates, and click generate. Remember, lottery odds don't improve with truly random selection!
Can I see my previous random number generations?
Yes, the history feature tracks your recent generations including range, quantity, and results. This is useful for record-keeping in raffles, verifying selections, or reviewing past generations for audit purposes.
Why Use a Random Number Generator?
Human-chosen numbers aren't truly random - we subconsciously favor certain patterns and avoid others. A true random number generator eliminates bias, provides verifiable randomness, and offers instant results for any range. Whether selecting lottery numbers, conducting fair raffles, making impartial decisions, or developing games, computerized random generation ensures statistical randomness that manual selection cannot achieve. The history feature also provides transparency and accountability for random selections.
