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.
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. RANDOM.ORG produces true random numbers from atmospheric noise, which for many purposes are better than pseudo-random numbers.
These pages contain real-time and historical statistics that measure various aspects of the true random number generator's operation. All random numbers generated by RANDOM.ORG are subjected to the tests below.
This page allows you to quick pick lottery tickets using true randomness, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.
RANDOM.ORG is a true random number service that generates randomness via atmospheric noise. This page explains why it's hard (and interesting) to get a computer to generate proper random numbers.
RANDOM.ORG is a true random number service that generates randomness via atmospheric noise. This page describes the statistical analyses that have been conducted of the service.
This page allows you to generate randomized sequences of integers using true randomness, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.
Our Core API lets your applications use true randomness from RANDOM.ORG's trusted technology. The Basic API gives you random values of many types and is useful for applications that require high-quality randomness, such as games and simulations.
Paste your list of up to 10,000 participants into our form and select the number of rounds you want, or simply roll the dice for a random number of rounds. Then randomize the rounds one at a time until you have your winner.
