What it trains

Why practice remembering numbers

This exercise works your short-term memory: you catch a row of digits in a second and hold on to it while you type the answer. A short number is easy to repeat to yourself. With seven or eight digits you have to split them into chunks, the way you do with a phone number.

The difficulty adapts to you: five correct answers in a row add a digit, three mistakes in a row take one away. Once you sign up, every game is saved and you can see a chart in your account.

Short-term memory

Hold a row of digits until you’ve typed all of it.

Order

It’s not just which digits, but where each one goes.

Chunking

A long number is easier to remember in groups of two or three digits.

Perception speed

The number shows for about a second, so there’s no time to study it.

Method

What the exercise is based on

The task is close to the classic digit span test that psychologists use to measure short-term memory capacity: a person repeats a row of digits, and the row gradually gets longer. In the test the digits are usually read aloud; here the number appears on the screen.

If you’d like to train memory for order without digits, try Corsi Blocks: there you repeat the sequence in which the blocks light up.

1 s4–5 digitsYou start with four digits, shown for about a second.

≈1 s6–7 digitsDisplay time ranges from 0.9 to 1.4 seconds depending on length.

0.8 s8 digitsThe longest number and the shortest display.

Questions

Frequently asked questions

What counts as a good result?

Compare yourself with yourself. At the end of a game you’ll see how many answers were right, how many mistakes you made and how long a number you remembered. Your account shows how this changes from game to game.

Why did the number get shorter?

Three mistakes in a row remove one digit. That’s how the game finds the length you can handle with confidence. Five correct answers in a row add a digit again.

Can I type on the keyboard?

Yes, you can type digits on your computer keyboard; Backspace deletes the last one. On phones and tablets there are on-screen buttons.

How do I remember long numbers?

Split them into groups of two or three digits, like a phone number, and say them to yourself. Long numbers are the perfect place to practice this trick.
