I am a pilot studying for my instrument rating (complicated procedures used for flying in clouds and low visibility) and I use your random number generator to generate simulated Air Traffic Control clearances. I substitute the numbers in for headings and bearings. It's great practice and I hope I'll ace the exam this way.

Thank you for offering the random number generator. I have used it for a research on the effects of target specific communications in a N=2000 population of Dutch War Veterans. In the experimental setting it was necessary to randomise the research population and to divide them over four sub-groups, similar in size. The only acceptable way was to do so by adding a randomised variable in SPSS. Afterwards it was possible to assign the subjects to one of the groups by sorting on the randomized variable. Of course I gave due credit in the report by mentioning your service and revealing the URL.

I just wanted to say thanks for the site. We use 5 digit long distance codes for our Osceola County phone system. Your site has made creating a random list of codes to issue to employees a breeze.

Dr. Haahr, I have attached an article about how the U.S. Army used your website to successfully seat random court-martial panels in Germany. I credited you for establishing and maintaining Random.org at footnote 56.

I just wanted to learn more about the world. I use numbers from your site to randomly pick 5 countries to pay a little extra attention to for the year. I also use the random numbers to come up with an age and sex for an imaginary citizen in that country and try to think about the country's recent history from their point of view.

Hi,

I'm just writing to say a big thank you for creating your lovely sequence generator. It has helped me so much in my area of psychological research, very simply by creating a sequence for me to administer experimental tasks. But without it, my job would have been a lot more difficult.

Thank you very much.

I found your RNG under ‘Google – I feel lucky’ search and used the integer generator for picking 3 sets of lottery numbers and won on one of them. What the heck, it worked! Thanks for the generator, it's fun.

I use Random.org to generate random attribute numbers for sports video games when creating new players. Useful for putting my friends in the game without being tempted to make them really good. Most of the time they wind up as an average to good player, and every now and then they wind up as a superstar.

Hi, I'm using Random.org to seed the PRNG Mersenne Twister to create random passwords at goodpassword.com.

I use Random.org to generate a random order for multiple stimuli used in human psychophysical testing. It's a welcome improvement over the book of random number tables I used in my youth, long ago.

A group of seniors at my high-school decided to hold a ‘Random Gift Exchange’ on a day that held no religious or political significance, for no reason other than it would be fun! I used the random integer generator (along with my list of gifters) to match people up with their ‘secret-santa’ partners, totally randomly! To make things even more interesting, each gift must cost an exact and random amount, and our price this time is $8.27, which was also randomly selected thanks to the random integer generator. I know our Random Gift Exchange will be a success thanks to Random.org!!

I'm a professional cellist, and I have a study book of about a thousand short technical exercises. I use your site like the sax player, Jeff, to pick a few at random to work on when I practise, so that I'm always working on a different aspect of my playing. It helps keep my music fresh.
