Excluding duplicate numbers
This option is appreciated by many users as it makes it possible to generate sequences of random numbers from a given range without repeatition.
We sometimes get feedback on Random Number Generator about getting duplicate numbers even if the "Remove duplicates" option is checked. It is not a bug. It could happen if the number of unique numbers exceeds the selected range. E.g. if you create 30 random numbers between 1 and 10, the range of numbers does not allow to generate 30 numbers without repetition. In this case you will receive a warning about duplicate numbers. In order to generate a set of random numbers without repetition, you can change either the amount of numbers or the range.
How you can use the Random Number Generator app
Random number generator is a must-have app when you need one or several random numbers. It produces random numbers based on your criteria and provides a range of useful options, which makes the app useful in a variety of situations.
With Random Number Generator

Random Number Generator is a great app for researchers, students and anyone who needs a quick way to generate random integers. There are many uses of random numbers in statistics. For example, the Random Number Generator app can be used to select a random sample from a finite population. Suppose there are 25 students in a class and you want to select two students at random.
Lists of random numbers for memory training
Due to the possibility of creating numbers of a certain length, you can create lists of random numbers for memory training. So, you can start with lists of 2-digit numbers, for example you can create a list of 10 numbers from 10 to 100, and then, increase the amount and the length numbers, creating lists of repeating or non-repeating 3-digit and 4-digit numbers.
If you need to generate a sequence of random numbers of a specified length, select "Random Number length" and enter the desired length. The maximum length is 100 digits. You may optionally select the 'Different adjacent digits' option in the Settings windows.
Simulating coin tossing
This generator can be used as the random coin flipper to simulate random coin tosses. It's very simple - assign one answer to "0" and the other one to "1", set the range from 0 to 1, enter the amount of generated numbers as "1" and press "Generate".
How to use Random Number Generator
To generate random numbers in a selected range:
- Select "Random numbers between" or "Two ranges".
- Choose the range of numbers - type the lowest and highest values. The lowest and the highest numbers should be selected from the range 1 - 999999999 and should have integer values. E.g. if you would like a random number between 1 - 100, enter '1' in the first field and '100' in the second one.
- Enter how many number you wish to generate. With the RNG app, you can create up to 200 random numbers. In the Settings window, you can choose if you want to display results in several columns or in a row.
- If you want to generate a set of random numbers without duplicates, so each number appears in the list only once, select the "Remove duplicates" option in the Settings windows.
- Click "Generate" to get random numbers based on the specified criteria.
How to save generated numbers
The online number generator
stores results until you close the page in the browser. Therefore, if you need to save generated numbers, copy and paste them in a file or send them via e-mail.
The mobile or computer version of Random Number Generator stores results until the application is closed. In the new version, we are planning to add the option that will allow users to choose whether generated numbers will be deleted from the history or not.
Generate passwords and sequences of random characters
As of version 3.0.0, the mobile version of the app for iOS also allows you to generate passwords and create random strings. You can generate up to 200 passwords or random strings. Each string should be up to 100 characters long and could contain uppercase and lowercase letters, digits and special symbols.

For example, if there are 50 participants, specify the range from 1 to 50.
The amount of numbers for generation should correspond to the number of winners in the contest.
Click the Generate button. Now you can make a screenshot of the result and place it on your webpage.
