Create a random sequence

Here is your chance to create a random sequence of one hundred zeroes and ones. Simply type your sequence in the text box below. There is no need to count: the text box will accept no more characters once you have reached one hundred.

When you have created your sequence and pressed the Test button, five tests described in the article will be performed on your sequence to determine if it is suitably random. The results of the tests are displayed by the lengths of the bars, colored red when the sequence fails the test and green when the sequence passes. More information about these tests and the pass/fail criteria is given in the main article.
