What this test measures
Most people reach level 7 to 10 in this sequence memory test, meaning they can repeat a pattern of 7 to 10 flashes in the right order. Level 12 or more is well above average; level 15 or more is exceptional and usually comes from grouping the steps into chunks.
This is a version of the Corsi block-tapping task, used in psychology since the 1970s to measure visuospatial working memory: how much location-and-order information you can hold in mind for a few seconds. It is related to how you remember routes, gestures and layouts.
How it works
- Press Start and watch: tiles light up one at a time.
- When the flashes stop, tap the tiles in the same order.
- Each correct answer adds one step. The first mistake ends the test.
Your score is the last level you completed, which equals the length of the longest sequence you repeated without a mistake (higher is better).
How to do your best
- Group the steps into chunks of three or four, like a phone number.
- Watch the whole grid, not each tile separately: patterns are easier than single points.
- Answer at your own pace; there is no time limit for repeating.
