We found Random.org through audiophile channels but have found so many other uses. We've turned hedge fund managers on to some of the tools. We've sent our staff acoustician the ‘white noise’ files which he seemingly uses. On a more simplistic level, we are using the random number generator to settle small bets in the office.

I play the Fantasy 5 which is part of the Florida lottery and I figured out that if I play 35 of the 36 numbers in 7 games without repeating that my odds of winning are 1:19518 instead of 1:376992. The only problem was that I need to play those numbers randomly in each game. Your random number generator has been helping ever since I've found it. Thank you very much!

I am a person who loves stats. I do a lot of bingo cards and games. I use Random.org for …

1. Bingo Game No. 1–75 for my 18,000 cards, 90 bingo variations
2. The game of Racko No. 1–60
3. Memory using the 0–9 numbers each game I use 10K numbers
4. Now with the deck of cards I can study card games more often, I play cards on paper, any game using a deck of cards
5. maybe you can do a shuffler using Uno or Skip Bo or other card games

I thank you for making the site. It saves me time. I used to do the old fashion way of making game numbers, using a bingo cage and balls.

6. I also use the lottery and Keno Numbers too…

Dr. Haahr,

I used a list of your new random numbers in your new set generator for the dog races on Friday March 14, 2008. Using your sets on the last 4 of 13 races generated 2 trifectas. The sets I use are chosen by calculating over and over until the sets generated line up with the previous winning numbers. In this particular case I used races 1 through 9 and matched them with the sets generated. Of course there is not a 100% match for all numbers. However, the way the races are set up, the 1st three finishing positions are the ones to key on.

I wanted to both thank you for your random number generator and apologize for hogging the numbers today (I used up my quota and then went to my coworker's computer to get more numbers). I had to generate 50,000 random numbers for a project at work with only a couple hours' notice—we’re producing cards for a client as part of an instant win game, and each one needs a unique code—and your generator saved the day.

Plus, my coworkers already think I have mystical intellectual powers, and when I can come up with a solution like this in 15 minutes, it boggles their minds.

By the way, I love the user interface and the design of your site—it's simple and easy to use for non-mathematicians, and it has a nice clean, elegant feel to it.

Thanks again!

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.

Just thought I would let you know that I use Random.org to generate Lotto numbers for my Clan (Drake Knights) on Mech Crusaders. It's perfect for a small lotto situation, great site, thanks.

Hello! I am an admirer of the Random.org web site! I have implemented a Virtual Coin Toss web page that allows multiple parties in different locations to perform a virtual coin toss which they all can verify separately. On this site, a virtual coin toss (ie, a zero or one) is fetched from random.org once every minute, is stored for some number of days, and can be looked up through a simple form. So, for instance, two individuals can agree to use the toss that will occur at some particular, approaching time; they can then separately view the coin toss as it occurs or look it up later.

My original reason to look for a random integer generator was to obtain some numbers for a lottery. However, independent of this specific intention, I wanted to use a ‘good and nice’ generator. Then I found yours and I like the principle on which it is based very much. Also it is very convenient because it offers many options. It was just the perfect generator for which I was looking for! I appreciate your work very much to establish this random integer generator.
