Testimonials

Hi, I just wanted to tell you thank you for the die roller on your site. I am a 5th grade math teacher. I developed a lesson on comparing decimals around a game, but I forgot to bring the dice to school. Your website saved my lesson! I was able to project the die roller on my Smartboard and we were able to play as a whole class. Thanks!

Just a quick note to say thanks for providing the service. I use a lot of things on the internet that almost do what you want, but Random.org saved me lots of time and gave me just what I wanted. I used it to generate lengths for some fibre optic lighting I'm having installed, just went through after and modified any adjacent numbers the same and it gave me exactly what I wanted. Easy to set the limits and size and shape of number results—great.

I just wanted to say thanks for the free services rendered from Random.org. I learned a lot from the site, including how truly inferior computer generated pseudo-randomness is. After learning all about random numbers, I updated my musical note generation program to use Random.org, instead of the Rnd() function in Visual Studio. Basically, I use the program when I am stuck in songwriting to help inspire/write parts of songs, and I feel that much more confident knowing that the notes are, in fact, truly random.

I have never been a very decisive person especially when it came to the more important decisions in life. Just recently I was shopping an online retailer in hopes of finding a wolf shirt, and ran into a decision making dilemma. You see, I am a huge fan of wolf shirts for the obvious reason that they speak volumes about a person from a single glance, personality (lone wolf), social habits (enjoys the night life), special talents (casting/bow staff handling). Said shirts, however, have a variable number of wolves howling at the moon, and I was not about to commit the major fashion faux pas of donning the wrong number this late in my 30's.

My first thought was to graph the number of wolves vs my percieved irresistibility but that ended up with a 2-way tie between 4 and 5 wolves. Neither my mother (who has always said that I am fairly handsome) nor my WOW guild were able to provide a convincing argument one way or the other, but I lucked out, and stumbled across your website which guaranteed me unparalleled randomness for breaking these kinds of deadlocks.

With a click the decision was made and at that point I took a deep breath of musty basement and literally jumped for joy at the new prospects that lay ahead of me in my life rattling my cat elf-fire. To make a long story short your site enabled me to buy the optimal wolf shirt, and my social life has blossomed ever since.

I am using the List Randomizer to randomize lists of music chords so as to improve my skill at sight-reading music by practicing moving quickly from one chord to another on my musical instrument (upright bass) without either mind memory or ‘finger memory’ interfering by allowing me to increasingly do the exercise without actually having to read the chords. (I have found this to be a major fault with books supposedly designed to improve sight-reading.)

While I am sure that for this rather pedestrian purpose, a PRNG would serve as well as a TRNG, yours was the first List Randomizer I found after long web sessions of searching, and it's perfect for what I need. The nondeterministic feature of your TRNG—while perhaps overkill for my purpose—is definitely appealing.

I'm tracking down high school classmates so we can notify them about our 35th reunion using internet searches. A fellow classmate created a spreadsheet with the 237 ‘missing’ classmates. After working on it for about a week, I realized I was just looking for people I knew and ignoring the rest. In order to do a fairer job searching for classmates, I decided to use your random number generator. Whatever number it generates, that's the row I do next in the spreadsheet. It also actually makes the process more fun, because I never know who I'll be looking for next.

Thanks for having this on the internet!

Many thanks for your interesting and useful site. The various interfaces are nice and clean, direct to the point. I recently used the list randomizer and integer generator (over the secure connection, of course) to create a truly random password. Once I had it memorized and had to dispose of the slip it was written on, I went through a fairly rigorous obfuscation process to obscure the data on the paper, then cut it up into pieces, and used your random value generators to decide which pieces were going to go into which garbage cans.

—Brian Mearns

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!

I want to thank you very much for your random number generator! We teachers are supposed to check for understanding with all of our students. I am sure you are aware of all the stumbling blocks to actually calling on students randomly. I hope that your random number generator, with its ability to generate integers within the range that I specify, will help me to better sample my students for their understanding. More important to the students is the classroom jobs like setting up the technology each day, passing out folders, etc. (I teach 6th Grade in the USA.)

The most important feature of your generator is the ability to set the range/limits!

I tried popsicle sticks in a can but found that method to be ‘uncannily’ unfair! It seemed like I kept getting the same sticks!

I tried writing numbers on index cards, but I can't shuffle cards to save my life! (Besides, when I pick the cards without looking, you know there is bias in that as well … somewhere in my brain.)

I finally purchased some dice from the net that have various numbers of sides. But that didn't work either because the number of students in my class changes throughout the year as the students in our area have a somewhat high transiency rate.

I was at a loss, and the students have been getting upset with me.

In the past I have Googled for something like this, but I guess I never quite put in the correct words to arrive at your site, but I THANK GOD THAT I FOUND YOUR SITE TODAY! And, yes, you may use this testimonial!

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.

—Mat Kaplan

Thank you for this valuable service. We hold prize and community event drawings for our employees and the convenience of your site is fantastic (and fair).

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!

—Cedrick Catalan

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!
