|RANDOM.ORG offers true random numbers to anyone on the Internet. People use RANDOM.ORG for holding drawings, lotteries, and sweepstakes, to drive games and gambling sites, for scientific applications, and for art and music. RANDOM.ORG’s randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.
