What can I say? Random.org is one of the most useful websites I've used in a long time. The website I run uses this service on a regular basis using it to select the winners of competitions and it's proved to be a very useful tool in doing so. Random.org is undoubtedly one of the unsung heroes of the internet. Thank you very much!

I recently ran a contest, and I quickly realized I would need an easy way to randomly pick a winner, something more random than closing my eyes and picking off of a screen. Upon some searching, I found the Random Integer Generator. With the program's help, I was able to input the amount of entries, and simply have it pick one for me... no work involved, and no chance of the results being "un-shuffled". It worked like a charm, and I had a winner picked in less than a minute! Needless to say, I will be using the Integer Generator for all of my future giveaway contests, as it's the single best resource I've found for this task. Thanks so much for making it freely available, and I will always link back to it (For anyone else who may be in the same situation) when I run contests!

After years of relying on your site, a random impulse has finally led me to say thank you. We've been relying on the Integer Generator for years. It helps us select the winner of our space trivia contest, a weekly feature of the "What Up!" segment of "Planetary Radio." PlanRad is the public radio series I produce and host for the Planetary Society, based in Pasadena, California. It is aired by about 150 stations in North America and beyond, along with XM Satellite Radio. Our podcast pulls in thousands of additional listeners. I can't say we promote random.org every week, but when the site is mentioned it is always in admiration. We are grateful. Best of luck in your business and other efforts.

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!

Thank you very much for your random number generator! I use it all the time. I have a monthly drawing on my site, so I use it to pick the two winners. So, thank you! I see you are visiting Georgia. Have a great time!

I help out with a internet poetry workshop and community called Neopoet. We elect members every three months to a board which governs the site. I discovered Random.org while stranded in an airport lounge on the eve of our first election. I was waiting for my delayed flight while I realized I'd forgotten to randomize the ballot order. I pulled out my Blackberry and started searching for a way to generate random numbers. I quickly found your Random Sequence Generator. I wrote down the candidates on a slip of paper, then the assigned sequences from your site. I was able to update the ballot just as the election was about to begin, and just a moment before the final boarding call was announced.

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!

As part of the classes I teach, I task my students with preparing a lot of presentations. To save time & reduce boredom, I occasionally have only a portion of the student teams give their presentations. I use your Sequence Generator to pick who presents (& in what order), after they're ready to present (to keep them focused & accountable). Great website; please keep up the good work!

Mr. Haahr, I thought I would drop you a line to say 'thank you' for your random.org pages. I am currently running a contest to celebrate the 10th anniversary of my website, and need an honest way to select winners from among the entrants. This evening I will have to make the first selection of winners and your tools will provide an excellent way of doing this ... thank you!

I produce 4 weekly booked open mics for stand-up comics in Manhattan. A typical show is only able to put up 24 comics in the two hour length of the show, and usually over 50 comics will reply to each week's invite to perform. How best to determine who gets on and who gets mad? You and your site have saved my bacon repeatedly. Thank you!

I am the founder and administrator of 911Lifeline.org, We are a forum, support, and resource center for public safety professionals who work as telecommunicators at 9-1-1 emergency dispatch centers. We provide our services via our Yahoo group, and our web site. We recently started drawings to recognize and reward our members. In particular, we are holding our first drawing to celebrate National Public Safety Telecommunicators Week. NPSTW is an annual event that takes place during the first full week in April. It was officially created by a proclamation signed in 1994 by former U.S. president Bill Clinton. If you are interested, you can read the proclamation at http://www.presidency.ucsb.edu/ws/print.php?pid=49952 Our members enter the drawings via email. At first, it was not clear how to fairly pick the winners, but then I became aware of Random.org. Each email is assigned a sequential number as it is received. Your random sequence generator is then used to randomize the entries. The first N numbers in the sequence, typically three, determine the winners. Thank you for your fine resource, and public service. Sincerely, Michael Wallach

Mr. Wizard is a monthly contest based on a pretty neat on-line card trick. A $50 cash prize is awarded each month to both the winner and person who referred the winner to our site. The winner is chosen by first sequentially numbering each entry as it arrives then using the Web interface at random.org to select one of the numbers.

I produce a high school quiz show in Dayton Ohio (USA). Each year we can only choose 36 high schools, & we typically get about 70 schools who wish to play. I assign a number to each school, then use random.org to generate the field of teams that will compete. It's a completely fair way to choose the schools.

Dear Mads, This is an expression of thanks for making your random number generator available. We use it to randomly draw winners in sweepstakes to promote Australian wine in Denmark! These sweepstakes will usually attract thousands of participants and we have found the generator, in addition to being extremely simple and quick to use, is a good reference if participants wish to know the method with which we draw winners.

USS CONSTITUTION, known better as "Old Ironsides". The oldest commissioned warship afloat in the entire world. We use your program to choose winners for our July 4th lottery. We get thousands of entries from across the world each year and only choose 150 winners. Winners receive an invitation to be onboard the ship during our Turnaround Cruise in Boston Harbor. Thank you for a great program.

We used it to generate the winner of 105,000 frequent flyer miles in a draw for an on-line survey conducted for a major international airline. That will get someone from Europe to Asia in Economy or Business Class to the Middle East/North Africa. Someone is pretty happy now! We normally do it internally on our own computer generator but the person who does that is on compassionate leave. So thanks for the use of your random.org. I'll make sure I credit you to our client..... Best regards from sunny Sydney

Greeting Mads, I'd like to thank you for having shared your random sequencer with the world and with me today! I am part of a statewide committee that is organizing the Secondary Literacy Summit IV, California's only conference for teachers and school principals dealing with literacy issues for middle schools and high schools. Finding your random sequencer was great today, and it will come in handy to create a raffle for our 410 participants. Visiting your website, I really enjoyed reading about your Smart Couch and wish you and your team luck in finding needed uses for this very unique concept.

We are a charter high school in Chesterfield, Virginia, USA. I use random.org to assign numbers to student applications. We always have more applicants than positions available, so the most fair way to determine who gets offered a position at our school is using random.org to generate random sequences for a lottery. Thank you for making this process so easy for me; no one can question the fairness of your truly random numbers.

Hello and thank you. You have provided an easy, unbiased and scientific format for me to pick sweepstakes winners. We are a full service direct marketing and promotions company in Chicago and often have the need to handle a sweepstake pick. We've used your site to pick sweepstakes winners of airline travel, baseball games, pool tables, and various other prizes. So for all those lucky winners - you really are randomly selected! Thanks again.

I am a medical librarian and yesterday I hosted an open house at the library to celebrate all the changes we have made recently. As part of our celebration (and for incentive to drop in) I offered door prizes. A friend in our tech dept helped me set up and configure an extra time clock so that all visitors had to do to register was swipe their employee badge. After downloading this to excel, I used your generator to generate 3 numbers to determine winners of our door prizes. Easy peasie, one two three-sie!

I just came upon your website while trying to generate random numbers on a spreadsheet. I hadn't installed the feature and I was too lazy to look for the CD! My purpose is rather lame, I suppose, but I'm in a monthly contest to win yarn from PT Yarn and I have to choose 15 of 31 yarn names for a lottery every month. Your number generator made it quick and simple.

Dr. Haahr, just a quick thank-you for your random.org website. I run a weekly contest for elderly residents of retirement homes in the US, and I have to select a prize winner from all the people who submit correct answers. So every week I assign sequential numbers to all the correct entries, and use your website to select the winner! Just thought you'd like to know your website is a valuable resource for us. Thanks again.

Channel 4 Interactive uses random.org to generate winners of the regular competitions we run on the site. As there can be anything up to 15,000 entries, it helps to have something genuinely random, so we don't get accused of bias.

Thank you for your website. We run a youth ministry program that has about 110 teens involved. During the month of March we decided to do a calendar, with prizes for each day, as a fund raiser. We sold 600 calendars. Instead of the traditional pulling numbers from a hat we decided to use your website to draw the daily winners. It is working out wonderfully. In a letter that we sent out with each calendar we mentioned your website and included a link. Thanks again for providing this service and may God Bless You.
