Corsi test: repeat the order in which the blocks lit up

Also known as: Corsi block-tapping test, Corsi test, spatial memory test

The blocks on the board light up one at a time. Tap them in the same order. The sequence grows after every correct answer, and the game goes on until two mistakes in a row. You can play 10 minutes a day without signing up. You get your result for free after entering your email: we’ll show it to you and send it to your inbox.

What it trains

What Corsi Blocks train

The exercise works your visuospatial working memory: you remember not only which blocks lit up but also in what order. There are no words or numbers here, only places on the board.

Your score is the longest sequence you repeated without a mistake. Once you sign up, it’s saved and you can see a chart in your account.

You forget the way you cameThe turns get mixed up on the way back
You can’t repeat steps you were shownSomeone showed you where to click in an app, and the order is gone
You mix up the order of actionsYou have to ask again what comes after what
You want to find your limitThe sequence keeps growing until you slip up twice

Spatial memory

Remember where on the board each block was.

Order

Hold a sequence, not just a set of places.

Memory span

Each correct answer makes the sequence one block longer.

Focus

Miss a single flash and you won’t be able to repeat it.

Rules

How to play

Watch
Press “Start”. The blocks light up one at a time, with a “Watch carefully” hint at the top.
Repeat
When the demo ends, tap the blocks in the same order.
Correct

Method

What the exercise is based on

The test was created by Canadian psychologist Philip Corsi in the early 1970s. In the classic version nine blocks are fixed to a board, the examiner taps them one by one, and the person repeats the sequence. It’s still used to assess visuospatial memory. Our version also has nine blocks; they just light up on the screen.

A similar order task, but with digits, is Remember the Number. And if you’d like to load your working memory in a different way, try N-back.

2→3Start with two blocksEach correct answer adds one block.

up to 9No repeatsWhile the length is nine or less, each block lights up only once.

10+With repeatsBlocks can light up again, but never twice in a row.

Who it’s for

Which ages

Adults

A quick check of your visuospatial memory: an easy way to follow how your best length changes.

Kids

It starts with just two blocks, and the rules make sense without words. It’s in the “Kids” collection. Suitable from age 6. Kids set

60+

Not part of the “60+” collection: the demo runs at a set pace, and the sequence grows quickly. A calmer memory task from the collection: What’s Missing?

Questions

Frequently asked questions

What counts as a good result?

Compare yourself with yourself. At the end of a game you’ll see your best length and the number of rounds, and your account shows how they change over time.

Is there a time limit?

No, there’s no timer. The game goes on until you make two mistakes in a row. A correct answer resets the mistake counter.

Why aren’t the blocks in a neat grid?

That’s how the classic Corsi test works: the blocks are placed unevenly, so the sequence is harder to reduce to a simple pattern.

Do I need to sign up?

No, you can play 10 minutes a day right away. A free account lets you keep playing, save your results, track your progress and unlock the daily workout.

Does it work on a phone?
