A run of digits appears for a few seconds, then disappears. Type it back from memory. Each successful round adds another digit, so you find your digit span in the same way a memory researcher would.

How it works
- A number appears and stays for a few seconds.
- When it vanishes, type it back.
- Get it right and the next number is one digit longer.
- One miss ends the run.
Worth knowing
Chunking digits into groups, such as 4-7-2 instead of 472, is a normal memory trick and usually helps.
