Measure visual short-term memory capacity
Your result has two parts. Points show the total number of correct sequence steps completed during the whole session, so they reflect overall performance and consistency. Level shows the longest sequence you were able to complete correctly, so it is the clearest indicator of your current memory span. In practice, level is the most direct measure of sequence length, while points give a broader view of how well you performed across the entire run.
This test measures visual working memory, sequence recall, and short-term attentional control. You must hold a growing pattern in mind, keep the correct order, and reproduce it accurately.
Repeated practice can support sequence recall, visual chunking, and steadier short-term concentration. For a broader memory profile, compare it with Number Memory and N-back.
Sleep quality, stress, distraction, device differences, and strategy all affect performance. Distractor mode adds extra interference, so drops there often reflect attention control as much as pure memory span.
Visual sequence tasks are often used as compact measures of working memory and short-term control. For broader context, see our article on working memory and N-back, tracking cognitive progress, and the open-access review on the structure of working-memory span abilities across adulthood.
No. This is a simple cognitive task for self-tracking and comparison. It is not a medical tool and does not diagnose any condition.
Working memory is sensitive to sleep, stress, attention, and distractions. Look at several sessions to estimate your baseline.
It adds interference: you must remember only the target tile and ignore the distractor. That increases selective-attention demands while keeping the same response rule.

You can often improve consistency and reduce errors with regular, short sessions. Improvements are usually gradual, so tracking over weeks is more meaningful than one day.

For training and self-tracking only; not a clinical or diagnostic instrument.
