Want to help shape RANDOM.ORG in the future? Take our 3-minute anonymous survey.
I use Random.org to generate numbers for questions I am going to ask the kids at school. I'm a maths teacher and often have trouble devising questions (especially for data handling!). It's great to be able to specify what kind of numbers I want, and how many. Thanks for taking a load of work off me!
