How this test works

This test measures your digit span: how many digits you can hold in mind for a few seconds. A number appears on screen, then disappears. Type it back. The first number has 3 digits, and each right answer adds one digit. You get two tries at each length, and two misses at the same length end the test. Your score is the longest number you typed back exactly right. Psychologists have measured digit span since 1887.
