Random.org – Website that Produces “True” Random Numbers

Random.org is a website that produces “true” random numbers based on atmospheric noise. In addition to generating random numbers, it has free tools to do things such as flip coins, shuffle cards, and roll dice. It also offers paid services to generate sequences of random numbers and act as a third-party arbiter for raffles, sweepstakes, and promotions.

Random numbers are generated based on atmospheric noise captured by several radios tuned between stations. People use RANDOM.ORG for holding drawings, lotteries and sweepstakes, to drive games and gambling sites, for scientific applications and for art and music.
