See how it works

Blocks appear one at a time in random positions — remember the order, then tap them back.

How it works

Blocks appear one by one

Blocks appear at random, non-overlapping positions on screen, one at a time, building a sequence.

Tap them back

Once the sequence ends, tap the blocks in the order they appeared — or in reverse, depending on the mode.

Difficulty adapts

Tap a set correctly and the sequence grows by one block; struggle and it eases back down.

Four ways to play

Classic

Tap back in the same order they appeared. Each block disappears once tapped correctly.

Reverse

Tap back starting from the last block shown — recall runs backward.

Sticky Classic

Same forward order, but every correctly-tapped block stays visible, leaving a trail.

Sticky Reverse

Reverse order, with the same sticky trail of correctly-tapped blocks.

What is the Corsi Block Tapping Test?

The Corsi Block Tapping Test is a visuospatial memory span task — the spatial counterpart to a digit span test. Instead of remembering numbers, you remember positions: a sequence of blocks appears on screen, one at a time, in random non-overlapping spots, and you reproduce the sequence by tapping the blocks in order.

How the exercise works

Each round shows a sequence of blocks, one at a time; the sequence length equals your current level
Blocks appear in randomized positions that don't overlap, so no two rounds look the same
Depending on the mode, you tap them back in the same order (Classic) or in reverse order (Reverse), starting from the last block shown
In the Sticky variants, a block you tap correctly stays visible instead of disappearing, leaving a visible trail through the sequence you've completed
Tap a set of rounds accurately enough and the level rises, adding one more block to the sequence; several weak sets in a row eases it back down

Why train visuospatial memory?

Trains visuospatial short-term memory — remembering positions and paths rather than symbols or words
Reverse mode adds mental manipulation on top of plain recall, the same way reverse digit span does for verbal memory
A well-known task in cognitive research, since visuospatial span often behaves differently from verbal span in the same person
Adapts automatically so every session stays at the edge of your current span

Short, frequent sessions beat occasional long ones — consistency is what moves your level.

Who it's for

Anyone who wants to test visual and spatial memory, not just verbal recall
People who found Memory Span too "verbal" and want the spatial equivalent
Students and professionals whose work leans on remembering layouts, paths, or positions
Anyone building a daily training habit — pair it with streaks

Frequently asked questions

What is the Corsi Block Tapping Test?

The Corsi Block Tapping Test is a visuospatial memory span task on BrainScale. A sequence of blocks appears on screen, one at a time, in random positions, and once it ends you tap the blocks back in order. It's the spatial counterpart to a digit span test — you're remembering positions instead of numbers.

Is Corsi Block Tapping free to play?

Yes. Corsi Block Tapping is free to play with no signup required to start. Creating a free account adds progress tracking and streaks; a premium plan removes free-tier session limits.

What's the difference between Classic, Reverse, and Sticky modes?

Classic has you tap the blocks back in the order they appeared, and each block disappears once you tap it correctly. Reverse has you tap starting from the last block shown. The Sticky variants of each keep every correctly-tapped block visible instead of hiding it, leaving a trail through the sequence.

How does the difficulty level adapt?

Your level sets the sequence length — how many blocks you need to remember. Tap a set of rounds accurately enough and the level rises, adding one more block; fall below the accuracy threshold across several rounds in a row and the level eases back down.

How is this different from Memory Span?

Memory Span tests verbal and numeric short-term memory — sequences of digits or letters. Corsi Block Tapping tests the visuospatial equivalent — sequences of positions on screen instead of symbols. The two often don't correlate perfectly in the same person, so training both gives a fuller picture.
