Instead of using a formula to generate ‘fake’ randomness, Random.org uses an external data source as an input, and applies some fearsome maths to produce a truly random sequence.
  • More widely used are so-called "Pseudo" Random Number Generators (PRNGs). These produce a sequence of numbers using a method (usually a software algorithm) which is sufficiently complex and variable to prevent the sequence being predicted. Our Random Number Generator uses this method.
  • The random number generator also lets you choose how many random numbers you can generate and their length so you can customize your desired result. The maximum number of random numbers that the generator can return at once is up to 500 which is probably more than you can ever need all at once.
