Sequence memory test:
how long a sequence can you reproduce?
Tiles light up in a sequence on a 3-by-3 grid. The sequence ends; you tap the tiles in the same order. Each cleared round adds one more tile.
Press Start. Tiles will light up in a sequence; reproduce the sequence in the same order. Each cleared round adds one more tile.
Want to actually improve the score?
Sequence memory responds well to daily practice. Blanked\'s Sequence mode runs this exact task across 36 levels at scaling difficulty.

This is a simplified visuospatial sequence-memory task. It is closely related to the Corsi block-tapping test, which has been used in cognitive psychology research since Phillip Corsi\'s 1972 doctoral thesis. The task: you see a sequence of positions briefly lit, then have to reproduce the same sequence in the same order. The longest sequence you can reproduce before making a mistake gives you a "span" (your level), which is a rough proxy for visuospatial working-memory capacity.
Typical adult span on Corsi-like tasks tops out around 5 to 7. The score depends on a combination of innate ability, attention at the moment of testing, and prior practice. The percentile labels on the result screen are calibrated to typical adult performance; they are approximate, not clinical.
What your score means
The result is more useful as a baseline to compare against yourself in a few weeks than as a leaderboard score. If you intend to improve, take the test now, write down your level, do daily practice for three weeks, then re-take. Trust the change in your own score more than any percentile bar.
For the full visual memory test (a parallel format that asks you to reproduce a set of positions all at once rather than in sequence), see the main visual memory test. For the number-recall version, the number memory test covers digit span.
Frequently asked questions
What does this test measure?
Visuospatial span: how long a sequence of locations you can hold in mind and reproduce in order. It is a simplified version of the Corsi block-tapping task used in cognitive psychology research since 1972.
What is a good score?
Typical adult span on Corsi-like tasks tops out around 5 to 7. Levels 8 to 10 put you in the top quartile. Levels 11+ are unusual and usually mean either prior practice or unusual visuospatial ability.
Can I improve my score?
Yes, this is one of the more trainable cognitive tasks (Klingberg, 2010). Daily focused practice produces measurable improvement within a few weeks. The Sequence mode in Blanked is built around exactly this paradigm at scaling difficulty.
Is this the same as Human Benchmark sequence memory?
The task structure is the same family (visuospatial span). The grid is 3x3 here rather than 3x3 with the same icon, and the result interpretation cites Corsi-task norms rather than visitor percentile bars. Both tests measure essentially the same cognitive function.
How do I get better?
Daily practice on the same task. Blanked's Sequence mode is the most direct route; it scales difficulty automatically across 36 levels in three worlds. Other practice options: try to memorise phone numbers without writing them down, practice the classical Simon-Says toy, or use mental rotation exercises.
