True Random Number Service
Nevertheless, the best data security practice is not to let anyone but yourself generate your most important passwords. Our flagship solution for holding verified drawings with up to 10 million entries. It is not always easy to decide what is heads and tails on a given coin.
What’s the fuss about true randomness?
Get inspired by how people are using our services for all sorts incredible things. From folks have found very creative uses for true random numbers. Random scales to help students of jazz guitar practice improvisation.
What’s this fuss about true randomness?
RANDOM.ORG offers true random numbers to anyone on the Internet. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs. People use RANDOM.ORG for holding drawings, lotteries and sweepstakes, to drive online games, for scientific applications and for art and music. The service has existed since 1998 and was built by Prof. Mads Haahr of the School of Computer Science and Statistics at Trinity College, Dublin in Ireland. Today, RANDOM.ORG is operated by Randomness and Integrity Services Ltd.

Perhaps you have wondered how predictable machines like computers can generate randomness. In reality, most random numbers used in computer programs are pseudo-random, which means they are generated in a predictable fashion using a mathematical formula. This is fine for many purposes, but it may not be random in the way you expect if you’re used to dice rolls and lottery drawings.

Coin Flipper
Numismatics (the scientific study of money) defines the obverse and reverse of a coin rather than heads and tails. The obverse (principal side) of a coin typically features a symbol intended to be evocative of stately power, such as the head of a monarch or well-known state representative. In the case of coins that do not have royalty or state representatives on them, the side that features the name of the country is usually considered the obverse.
