Frequently Asked Questions
What is a random number generator?
A random number generator (RNG) is a tool that produces random numbers within a specified range. Our generator uses a pseudo-random number generator (PRNG) algorithm to create statistically random numbers. You can set minimum and maximum values (0-10,000), control duplicates, and sort results in ascending, descending, or random order.
How do I generate random numbers online?
To generate random numbers: (1) Set your minimum and maximum values between 0-10,000, (2) Choose how many numbers to generate (1-1,000), (3) Toggle whether to allow duplicate numbers, (4) Select sorting preference (ascending, descending, or unsorted), (5) Click Generate. Your random numbers appear instantly and can be copied in multiple formats.
Can I generate unique random numbers without duplicates?
Yes! Toggle the "Allow Duplicates" option to "No" to generate only unique numbers. When duplicates are disabled, the maximum quantity you can generate is limited by your range size. For example, a range of 1-100 allows up to 100 unique numbers.
What output formats are available for copying?
You can copy generated numbers in four formats: (1) Comma-separated: "1, 2, 3, 4", (2) Space-separated: "1 2 3 4", (3) Spreadsheet Row: tab-separated for pasting into Excel/Google Sheets rows, (4) Spreadsheet Column: one number per line for pasting into columns.
Is this random number generator really free?
Yes, completely free! RandomHub's random number generator requires no registration, no credit card, no subscriptions, and has no usage limits. Generate unlimited random numbers for lottery picks, PIN codes, statistical sampling, gaming, education, or any other purpose—forever free.
How can I use random numbers for lottery or PIN generation?
For lottery numbers: Set your range (e.g., 1-49 for many lotteries), set quantity to match your lottery (e.g., 6 numbers), disable duplicates, and generate. For PIN codes: Set range 0-9, set quantity (e.g., 4 or 6 digits), allow duplicates, and generate. You can sort ascending if you prefer organized numbers.
Are these numbers truly random or pseudo-random?
Our generator uses a pseudo-random number generator (PRNG) algorithm, which produces statistically random numbers suitable for most applications including games, education, statistical sampling, and general purposes. PRNG numbers are not suitable for high-security cryptographic applications, but are perfect for everyday randomization needs.
What is the maximum range and quantity I can generate?
You can generate random numbers in a range from 0 to 10,000 (both minimum and maximum can be set anywhere within this range). You can generate up to 1,000 numbers in a single generation. When duplicates are not allowed, the maximum quantity equals your range size (max minus min plus one).

About Random Number Generators
A random number generator (RNG) is a computational tool that produces sequences of numbers with no predictable pattern. There are two main types: pseudo-random number generators (PRNGs) use mathematical algorithms to generate statistically random numbers quickly and efficiently, while true random number generators (TRNGs) rely on physical phenomena like atmospheric noise or radioactive decay for genuine unpredictability.
Our generator uses a PRNG algorithm, which is perfect for most everyday applications including gaming, education, statistical sampling, lottery number selection, prize drawings, and general randomization needs. PRNG algorithms are fast, efficient, and repeatable for testing purposes, while still providing the statistical randomness required for fair, unbiased number generation. For high-security cryptographic applications requiring true randomness, specialized TRNGs should be used instead.
Random number generation has countless applications across industries: cryptography for generating encryption keys, scientific research for Monte Carlo simulations, gaming for damage calculations and loot drops, statistics for sampling and hypothesis testing, education for creating practice problems, and entertainment for lottery picks and prize drawings. Our tool brings professional-grade RNG capabilities to everyone—free, fast, and accessible from any device.
