Random Number Generator
Generate random numbers within any range
Frequently Asked Questions
Are online random number generators truly random?
Most online generators use pseudorandom algorithms (PRNG), which are deterministic but produce statistically random sequences. For everyday use like games, raffles, or sampling, PRNGs are perfectly adequate. Cryptographic applications require hardware-based true random number generators.
What is a seed in random number generation?
A seed is the initial value used to start a pseudorandom sequence. The same seed always produces the same sequence, which is useful for reproducibility in simulations and testing. Most generators use the current time as a default seed.
Can I use this for lotteries or giveaways?
This generator is suitable for casual draws and classroom activities. For official lotteries or legally binding giveaways, use a certified random number generator and document the process for transparency.
