What this measures
Your visuospatial sequence span — the length of an ordered sequence of positions you can hold and reproduce. It is not an intelligence test and does not predict anything away from this game.
It grows by one each level — how far can you go?
Where this task comes from
Repeating a sequence of lit positions that grows by one each round is the shape of the Corsi block-tapping task, a spatial span measure that has been in use since the nineteen-seventies; Kessels and colleagues (2000) published the standardisation most laboratories cite. This page is a browser version of that shape rather than that measure: the tiles are on a screen you supply, the pacing is ours, and nothing here is administered or interpreted the way a laboratory instrument is.
How to read your number
Your number is the longest order you gave back before the run ended — a span on this grid, on this device, today. There is no norming sample behind it, so it carries no percentile and places you against nobody. The only comparison it supports is with your own earlier runs, and even that moves: a span is one of the easier things to lose to a bad night or a noisy room.
What changes your number
Sleep and time of day move it. The device moves it — a phone’s smaller grid and a thumb’s travel are not a mouse and a monitor. Plain practice at this task moves it, because the second run of anything is partly a run at a format you have already learned. And an interruption costs a span outright: a sequence you are holding does not survive a notification, which is a fact about how holding works and not about you.
Questions
- What does this measure?
- Your visuospatial sequence span — how long an ordered sequence of positions you can hold and reproduce. The level you reach is that span. It is not an intelligence test and does not predict anything away from this game.
- What is a good level?
- We do not publish one — there is no norming sample behind any number here, so any level we named would be invented. The sequence grows by one every level, so the run gets harder until it ends; the level you reached last time is the thing to beat.
- How is my score decided?
- By the longest sequence you reproduce correctly, in order. One wrong tile ends the run — the level you had completed is your score.
- Does practising make me smarter?
- No — you get better at this task, which is a real and honest thing to get better at. We do not tell you it transfers to work, school, or IQ.
