How to use
Choose an inclusive range, quantity, duplicates and sorting, then generate a batch.
Choose how many numbers
Choose 1 to 1,000 results. For unique numbers, the requested count must fit in the range; invalid requests show an error instead of a partial result. These are application guardrails.
Copy your results

Frequently asked questions
- How are the random values generated?
- The browser's Crypto.getRandomValues supplies cryptographically strong pseudorandom bytes. Rejection sampling avoids modulo bias within the supported range. This is not a physical true-random source or a lottery prediction tool.
- Can the random number generator be used for lottery number selection?
- Yes, the random number generator is perfect for lottery number picks. Set the range to match your lottery's number pool (e.g., 1-69), enable unique numbers, and generate your set of random picks instantly.
